DEBATE ON GLOBAL WARMING!!!!!!!!!!!!!!

By: Fshhead , 6:19 AM GMT on February 22, 2007

This is my continuing blog on global warming. If you are new visitor, please look at last couple of blog entrys also on global warming!!!!







"There are so many arguments proving & disputing global warming that people can't seem to agree completly on it. But for all the preperations that we make for hurricanes & other disasters, what do we have to lose if we prepare for global warming as if the worst might come true?
The answer is pure common sense. We should try to eliminate the variables that cause global warming instead of just arguing about it. It's like a hurricane- if we prepare for the worst, it can only save lives & money. If it does not come, no one will have been hurt & we may even have a healthier Earth."

Changes on Neptune Link Sun and Global Warming

Skeptics of manmade global warming have found further support in research linking solar output with the planet Neptune’s brightness and temperatures on Earth.

The findings appeared in a recent issue of Geophysical Research Letters. The authors of the article, H.B. Hammel and G.W. Lockwood from the Space Science Institute in Colorado and the Lowell Observatory in Arizona, note that measurements of visible light from Neptune have been taken at the Observatory since 1950.

Those measurements indicate that Neptune has been getting brighter since around 1980. And infrared measurements of the planet since 1980 show that Neptune has been warming steadily as well.

The researchers plotted on a graph the changes in visible light from Neptune over the past half-century, changes in temperatures on Earth during that period, and changes in total solar irradiance.

The results: The correlation between solar irradiance and Neptune’s brightness was nearly perfect; so was the correlation between changes on Earth and solar output, according to a report on the research appearing on World Climate Report, a climate change blog.

“When the sun is more energetic and putting out more energy, the Earth tends to warm up, and when the sun cools down, so does the Earth,” World Climate Report notes. “The Hammel and Lockwood article reveals that the same is true out at Neptune — when the sun’s energy increases, Neptune seems to warm up and get brighter . . .

“How is it possible that the Earth’s temperature is so highly correlated with brightness variations from Neptune? The news from Neptune comes to us just weeks after an article was published showing that Mars has warmed recently as well.

“If nothing else, we have certainly learned recently that planets undergo changes in their mean temperature, and while we can easily blame human activity here on the Earth, blaming humans for the recent warming on Mars and Neptune would be an astronomical stretch, to say the least.”

As I see it, the impact of global warming on the FREQUENCY of hurricanes is still unknown. It may be that a global warming world will shift towards a permanent or semi-permanent El Nino situation, which may surpress tropical cyclone formation

Well Simon, this is the way I understand it. They said that FREQUENCY of hurricanes would not increase due to GW BUT, they did say that the storms that do form would be stronger & more intense. They also said the frequency could actually DECREASE due to the fact that El-Nino events would happen more frequently!
As far as the fires here in Fla. Well this is a natural process that has to happen. The fires clear out the lower brush, exposing the soil.Then the pines release their seeds due to it & settle in the fresh dirt. Fires ARE a necessary evil here unfortunately. As far as Cal. not really sure & I am not sure if they are increasing or not.

The hurricane issue is one that I have had many spirited "debates" with here. This I believe is one of the biggest signs of global warming. It's just common sense to me. Higher temps. & higher Sea Surface Tempuratures lead to more powerful hurricanes. Just look at how some of these hurricanes have just totally bombed in a short amount of time (Wilma, Katrina etc..). Then you throw in the anomolies like the storm off Brazil & typhoon Loke(which nearly tracked the Pacific from side to side as a cat. 5 typhoon)along with all the other anomolies. If you ask me it's pretty much a no brainer, the storms ARE being influenced by global warming.

Warming linked to stronger hurricanes
SETH BORENSTEIN
Associated Press
PARIS - Global warming has made stronger hurricanes, including those in the Atlantic such as Katrina, an authoritative panel on climate change has concluded for the first time, participants in the deliberations said Thursday.

During marathon meetings in Paris, the Intergovernmental Panel on Climate Change approved language that said an increase in hurricane and tropical cyclone strength since 1970 "more likely than not" can be attributed to man-made global warming, according to Leonard Fields of Barbados and Cedric Nelom of Surinam.

In its last report in 2001, the same panel had said there was not enough evidence to make such a conclusion.

"It is very important" that the language is so strong this time, said Fields, whose country is on the path of many hurricanes. "Insurance companies watch the language, too."
The panel did note that the increase in stronger storms differs in various parts of the globe, but that the storms that strike the Americas are global warming-influenced, according to another participant.
Fields said that the report notes that most of the changes have been seen in the North Atlantic.
The report - scheduled to be released Friday morning - is also a marked departure from a November 2006 statement by the World Meteorological Organization, which helped found the IPPC.

The meteorological organization, after contentious debate, said it could not link past stronger storms to global warming. The debate about whether stronger hurricanes can be linked to global warming has been dividing a scientific community that is otherwise largely united in agreeing that global warming is human-made and a problem.

Massachusetts Institute of Technology professor Kerry Emanuel, who pioneered much of the research linking global warming to an uptick in hurricane strength, looked at the original language in an IPCC draft and called it "a pretty strong statement."

"I think we've seen a pretty clear signal in the Atlantic," Emanuel said. The increase in Atlantic hurricane strength "is so beautifully correlated with sea surface there can't be much doubt that there's a relationship with sea surface temperature."

But U.S. National Hurricane Center scientist Christopher Landsea has long disagreed with that premise. While he would not comment on the IPCC decision, Landsea pointed to the meteorological organization's statement last fall.

That was taken right from the report!!!!!
I also believe that is the reason the Pacific typhoon season has been especially rough for a few years now.

cruc, nothing in the study about storms, just hotter summertime heat waves.

A study released by Nasa's Goddard Institute for Space Studies at Columbia University finds that by 2080 average summer high temperatures in parts of the east will be about 10F higher than now, pushing them from the low to mid-80s to the low to mid-90s.

A study was done and the results were released. I don't see anyone staking their reputation on it. As a matter of fact the language seems appropriately cautious.

"Our analysis shows that there is the potential for extremely hot summertime temperatures, especially during summers with less-than-average rainfall," confirmed the Nasa researcher Barry Lynn, who is also a lead author of the new report.

A repeat here ALSO!!

Not so fast Crucilandia, ahhhh as far as the hurricanes that is NOT what they are saying. The report even said that the Atlantic seasons ARE influenced by AGW. I don't have time now but, if needed I know I posted that earlier, right from the report. As far as the tornadoes & such, well we will see in a few years when more data comes in. The only thing I see is that more tornadoes would form cause of higher temps. clashing with existing cold fronts. Makes sense to me that there would be more but, thats my theory!

A repeat here.

In the IPCC report there is a footnote on the issue of global warming and extreme weather: "Magnitude of anthropogenic contributions not assessed. Attribution for these phenomena based on expert judgment rather than formal attribution studies."
In other words, the link between stronger hurricanes and global warming is a theory (expert judgment) and is not a conclusion of the IPCC. it is difficult to make a strong statement saying that global warming is responsible for stronger hurricanes, due to the high natural variability of these storms and the poor observational record: "multi-decadal variability and the quality of the tropical cyclone records prior to routine satellite observations in about 1970 complicate the detection of long-term trends in tropical cyclone activity

Here's the relevant statement in the 2007 IPCC report:

There is insufficient evidence to determine whether trends exist in small scale phenomena such as tornadoes, hail, lighting, and dust storms.

Hurricanes, tornadoes and thunderstorms are analogous to those occurred in the past

US 'bids to water down global warming declaration'


Peter Walker and agencies
Friday May 11, 2007
Guardian Unlimited


The US is fighting to water down a declaration on global warming being prepared for next month's G8 summit, it was reported today.
Reuters said Washington was objecting to specific targets and arguing against significant UN involvement.

The US stance risks provoking a major rift with Germany, which hosts the annual summit of the G8 industrialised nations in the Baltic Sea resort of Heligendamm between June 6 and 8.

Reuters reported that Washington was objecting to pledges to limit global temperature rises by 2C this century and to reduce total world greenhouse gas emissions to 50% below their 1990 levels by 2050.

The US has also questioned whether the UN is the best forum to tackle the issue, and has rejected a section of the declaration saying that carbon trading markets are a way of developing alternative technologies.
"They have rejected any mention of targets and timetables, don't want the UN to get more involved and refuse to endorse carbon trading because it must by definition involve targets," Reuters quoted a "well placed" source as saying.

The German chancellor, Angela Merkel - whose country holds the rotating G8 presidency - will host the leaders of fellow members Britain, the US, Russia, Canada, Japan, Italy and France.

Leaders from China, India, South Africa, Mexico and Brazil will also attend the meeting.

Ms Merkel has spoken of her determination to push through an ambitious plan to combat global warming following an EU-wide deal agreed in March. However, she faces resistance from the US and Canada.

"There is a very serious game of poker being played, which is very disappointing at this late stage and given the scale of the problem," Reuters quoted another source as saying.

"It is an open question whether Merkel will be prepared to accept a watered down declaration or break with G8 tradition and declare a failure on climate change. Either way, the ink will still be wet when the final declaration is made."

The only current international agreement on the issue, the Kyoto protocol - which has never been signed by the US - effectively expires in 2012, and negotiations to find a successor have so far proved extremely sluggish.

It is hoped that a strong declaration at the G8 meeting could prompt progress at a major UN-arranged summit of world environment ministers in Bali in December.

why people from NASA are putting their reputation on the line stating that storms extremes are related to 'anthropogenic' global warming, and that they will increase to no end until 2080? Nobody can predict for sure what the weather will be in the next 7 days. Models can be twitched to show what they want.

I do't know but my figures are not uploading, but I have graphs showing that F3-5 tornado numbers is invariable since 1950, actually is decreasing the number since the 1970's

... broaden the hybrid and alt-fuel rebates, and make them results-oriented ...

Zaphod, that's an excellent idea! I hope you have written or called your congressional representatives to express this regardless of their political affiliation. I will also and I urge everyone else who likes the idea to do the same.

I am starting to really like the Prius. If they incorporate the lithium-ion batteries along with plug-in capability then use ethanol as the "liquid" fuel I think they could be on to something. Very versatile & extremely efficient. I would really like to see some solar power used in future models. One things for sure, they are the company that can bring all this technology to largescale production!!

Toyota's lithium-ion battery, under development with Matsushita Electric Industrial Co., was technically ready to be mounted on hybrid cars "any time".

More great news. If I'm not mistaken those batteries are significantly lighter and should improve mpg even more.


Well like I pointed out, the Tesla batteries are lithium-ion & Tesla Motors says that they will get OVER 200 miles to a charge. WOW, you match that with the already impressive mileage that a Prius gets & NOW you are on to something. THAT will reduce our oil consumption for sure. I sure am glad that in the past year ALOT of advances have been made & it "looks" like we are on our way to energy independence. That is such a GOOD thing!!!

Do CFLs contain mercury?
CFLs contain a very small amount of mercury sealed within the glass tubing – an average of 5 milligrams, which is roughly equivalent to an amount that would cover the tip of a ball-point pen. No mercury is released when the bulbs are intact or in use. By comparison, older thermometers contain about 500 milligrams of mercury. It would take 100 CFLs to equal that amount.

Thanx for the link LowerCal, found this little tidbit while looking at it!!!!

Scuttlebutt is mid-90's EPA MPG for the next Prius, with an optional plug-in charger feature.

If those wonderful liberal Dem's were serious about mileage, they would broaden the hybrid and alt-fuel rebates, and make them results-oriented, not corporate welfare. The existing mechanism is skewed toward getting every brand to sell something barely acceptable, rather then incenting the buyer to pick the best vehicle available.

Let's listen to the liberals as they chortle gleefully as the gas prices go up to match Europe, negatively affecting all but the gov't tax stream and the oil company investors. No new refineries in 30 years plus growth in consumption equals shortages, which generates price spikes. No magic at work here!

... the second-generation Prius ... sales began to suffer late last year after US tax credits whittled down for the model, prompting Toyota to offer incentives of up to US$2,000 on each Prius.

Pundits said that was pressuring already-tough margins on the hybrid. But Takimoto said he saw little impact on profitability before and after the incentives appeared ...


Great news but somewhat embarassing to me as an American since the tax breaks for heavy duty SUVs was kept in place when the Prius incentives where thrown out. (Write your congressional representative and tell them how you feel about that!)

... Toyota's lithium-ion battery, under development with Matsushita Electric Industrial Co., was technically ready to be mounted on hybrid cars "any time".

cruc, here's an excellent resource for finding out which CFLs are suitable for various needs, Find an Energy-Saving Light Bulb - Environmental Defense.

Fish, there's one sentence in that Wal-Mart article that needs clarification.

The bulbs are not supposed to be thrown away with household waste but as yet there is no system for collecting and recycling them.

While there may be no national system in place I think many communities do have a system in place similar to my own. Household hazardous was waste can be taken to a central collection point for a large area. There are also "roving" collection stations that set up a couple weekends a year for neighborhoods within the larger area.

Here's a great link for info on CFLs, Compact Fluorescent Light Bulbs : ENERGY STAR. At the bottom it contains a link, Information on Proper Disposal of Compact Fluorescent Light Bulbs (CFLs), that includes the safe procedure to follow if you accidentally break one in your home. The first step is

1. Open a window and leave the room (restrict access) for at least 15 minutes.

and the remaining steps are just as simple. At no point is the house declared a biohazard, LOL.

Stifling summers forecast by Nasa for US east coast
Source: Copyright 2007, Independent (UK)
Date: May 11, 2007
Byline: David Usborne
Original URL



Researchers at Nasa have warned that unless growth in greenhouse gas emissions can be successfully curbed, large areas of the eastern United States, from Washington DC to Florida, can expect to suffer through catastrophically hotter summers within just a couple of generations.

A study released by Nasa's Goddard Institute for Space Studies at Columbia University finds that by 2080 average summer high temperatures in parts of the east will be about 10F higher than now, pushing them from the low to mid-80s to the low to mid-90s.

Moreover, in particularly dry years with only limited rainfall to cool conditions, average high temperatures in cities as far apart as Atlanta, Washington DC and even Chicago to the north could peak at a baking 110F roughly the kinds of readings seen today only in the desert south-west.The institute made its projections after studying data from the past 30 years and using computer models to predict future trends. The study is unusual because it attempts to draw conclusions for a limited geographical area including individual metropolitan areas.

"Our analysis shows that there is the potential for extremely hot summertime temperatures, especially during summers with less-than-average rainfall," confirmed the Nasa researcher Barry Lynn, who is also a lead author of the new report. "Using high resolution weather prediction models, we showed how greenhouse gases enhance feedbacks between precipitation, radiation, and atmospheric circulation that will likely lead to extreme temperatures in our not-so-distant future," he added.

Such a dramatic jump in thermometer readings could have a devastating impact on health in America's largest cities as well as on agriculture and general economic conditions. It would also put significant extra demand on electricity producers for air-conditioning, raising emissions further.

The study is based on the "business-as-usual" premise which assumes that carbon dioxide emissions will continue to increase in the US at a rate of 2 per cent a year. But the scorching of the eastern US would intensify if those emissions grow.
Highlighted in the study is the role played by the eastern Pacific Ocean in determining summer conditions on the eastern seaboard of the continent. "Relatively cool waters in the eastern Pacific often result in stubborn summer high-pressure systems over the eastern states that block storms, reducing the frequency of precipitation below normal," said the study's co-author Richard Healy of the Woods Hole Oceanographic Institution in Massachusetts. "Less frequent storms result in higher surface and atmospheric temperatures that then feed back on the atmospheric circulation to further reduce storm frequency and raise surface temperatures even more."

The report was published too late to be included in the findings of the Intergovernmental Panel on Climate Change recently submitted to the United Nations. But it will be seized upon by those pressing governments to take more urgent steps to curb emissions.

It also comes days before the opening on Monday of the Large Cities Climate Summit in New York, a forum at which mayors from 30 of the largest metropolises, including London, Paris, Tokyo and Istanbul, will discuss plans for combating global warming.

Ken Livingstone, the Mayor of London, is also due to tour New York's emergency response centre which was built after 9/11 to co-ordinate the handling not just of terror-related incidents but also of climate-induced events such as hurricanes and flooding.

Toyota Says Hybrid Cost Premium to Disappear

TOYOTA CITY, Japan - Toyota Motor Corp. expects to cut costs for hybrid cars enough to be able to make as much money on them as it does on conventional gasoline cars by around 2010, a top executive said on Thursday.


Japan's top automaker has been keen to see the fuel-saving powertrain enter the mainstream since launching the Prius, the world's first hybrid car, in 1997, but sales have come at the expense of profitability given their high production costs.
But Masatami Takimoto, executive vice president in charge of powertrain development, said cost-cutting efforts on the system's motor, battery and inverter were bearing fruit, and the cost structure would improve drastically by the time Toyota reaches its sales goal of one million hybrids annually in 2010 or soon after.

"By then, we expect margins to be equal to gasoline cars," he told Reuters in an interview at Toyota's headquarters in Toyota City, central Japan.

If it succeeds, Toyota, on its way to becoming the world's biggest carmaker(already is!!), will be removing the main hurdle to cost-competitiveness for the hybrid -- the expense of the powertrain, which twins a conventional engine with an electric motor. It will also likely widen its sales lead as more consumers seek better mileage amid rising fuel costs.

Data this week showed US gasoline prices at an all-time high above US$3 a gallon, and Takimoto said he expected energy prices to continue rising.

Toyota likely achieved cumulative hybrid sales of one million units this month, having moved 998,900 by the end of April. By 2020, Takimoto said he expected hybrids to become the standard drivetrain and account for "100 percent" of Toyota's vehicles.
In 2006, it sold 313,000 units, accounting for the majority of the world's hybrid cars, and aims to lift that to 430,000 units this year with ramped-up production of the popular Prius.

With endorsement from Hollywood stars such as George Clooney, Toyota struggled for years to keep up with demand for the second-generation Prius. But sales began to suffer late last year after US tax credits whittled down for the model, prompting Toyota to offer incentives of up to US$2,000 on each Prius.

Pundits said that was pressuring already-tough margins on the hybrid. But Takimoto said he saw little impact on profitability before and after the incentives appeared, mainly thanks to larger volumes -- Prius production will rise by 40 percent to 280,000 units this year -- and the ongoing efforts to shave costs.

"There really hasn't been that much of a difference in margins," he said, adding: "In a sense, you could say things are finally normalising now. The Prius will soon enter its fifth year, and all this time we had no incentives on it."
Toyota does not disclose its costs or margins on its cars.

Industry watchers expect the current Prius to be remodelled late next year or in early 2009, using a lithium-ion battery (the battery in the Tesla) for the first time. Takimoto declined to confirm the speculation, but added that Toyota's lithium-ion battery, under development with Matsushita Electric Industrial Co., was technically ready to be mounted on hybrid cars "any time".

Wal-Mart cuts mercury in compact fluorescent light bulbs
The Associated PressPublished: May 10, 2007

BENTONVILLE, Arkansas: Wal-Mart Stores Inc. will lower the amount of mercury in high-efficiency compact fluorescent light bulbs it sells, a move to reduce an environmental downside to a technology widely touted by green groups as a way for ordinary consumers to help reduce global warming.

The world's largest retailer, part of a coalition pushing the so-called CFL bulbs as an alternative to traditional incandescent lights, said Thursday it has worked with its suppliers to reduce the amount of mercury in CFLs by as much as a third this year.

Wal-Mart is the biggest corporate member of a coalition launched in February of companies and government agencies to persuade more Americans to use the swirly shaped CFL bulbs. The coalition dubbed "18Seconds" says by using the bulbs, consumers will require less energy from coal-burning power plants and thus reduce greenhouse gas emissions.

Wal-Mart said in a statement it worked with manufacturers GE, Royal Philips, Osram Sylvania and Lights of America to reduce the amount of mercury in the bulbs. The reduction will cut an average of 360 pounds (163 kilograms) of mercury per 100 million compact fluorescent light bulbs sold, or 33 percent.

"According to the U.S. Environmental Protection Agency, coal-fired power plants emit four times more mercury to power an incandescent bulb than to power a CFL, emitting 13.6 mg (milligrams) of mercury compared to just 3.3 mg for a CFL," Wal-Mart said.
Wal-Mart has a goal of selling 100 million CFLs this year and has increased shelf space for the bulbs and the variety it sells.

Amid praise for the energy efficiency of CFLs, some environmentalists have been concerned that — unlike traditional bulbs — they contain small amounts of mercury that could escape if bulbs are tossed away with the trash. The bulbs are not supposed to be thrown away with household waste but as yet there is no system for collecting and recycling them.

However, green groups including the Sierra Club have said the mercury in CFLs is still less than the amount that would be produced by burning the amount of coal needed to power less efficient bulbs.

Wal-Mart and another environmental group, the Natural Resources Defense Council, said the retailer's move to reduce mercury to less than 5 milligrams per bulb would alleviate mercury concerns about CFLs.

Since the topic is about the bulbs, found this also!!!! Well it seems like the "debate" is over with the bulbs not unlike the "debate" over Anthropogenic global warming LOL So like I said I encourage everyone to get these bulbs!

The sizes of CFL's have continued to decrease too. You can now find CFL replacements for a 100 watt incandescent bulb that are so close in size that they can replace an incandescent in almost any fixture.

fluorescent lights.

They were bulky. They were expensive, as much as $25 each. They had an annoying flicker and hum. They cast an icky, cold-white light that made people look pale, wrinkly and old. . . A new breed of bulbs solves most, if not all, of the old gripes. The bulbs are smaller and much cheaper -- often selling for as little as $1.50 each at big-box stores. . . The hum and flicker are long gone, and many bulbs are designed to mimic the soothing, yellowish warmth of incandescent bulbs. (Most, though, still do not work on dimmers.)

Harmful Effects of Standard Fluorescent Lighting

Few doubt the advantages of newer lighting technology over standard fluorescent lighting developed decades ago. Standard technology’s focus was on efficiency—how to produce the most light for the least cost. The problem was that this technology produced lighting with a green or purplish hue. Worse yet, the cheaper magnetic ballasts cycle at a frequency which is perceptible by the brain, and caused many people to become sick or nauseated. Those prone to epileptic seizures were more susceptible when in this light, and some people would get migraine headaches. In Europe, Germany went so far as to ban cool-white fluorescent lights from government offices.

don't forget natural emissions are a significant source for bioaccumulation of mercury

One disadvantage of compact fluorescents is that each bulb contains a small amount of mercury, roughly one-fifth the amount in a watch battery. This mercury is only a small fraction of that released into the atmosphere by the additional coal burned to power an incandescent.

That article was a great find Fish! I'd like to call attention to the following also ...

Mercury released by coal-fired power plants is the principal reason why 44 of the 50 states in the United States have issued mercury intake advisories limiting the consumption of fish from freshwater streams and lakes. Nonetheless, worn-out compact fluorescents, watch batteries, and other items that contain mercury still need to be recycled properly. Fortunately, this is possible, whereas the mercury spewing from coal smokestacks blankets the countryside, ending up in the water and food supply.

crucilandia evryy bit helps to reduce your emissions for as you become aware, you talk about it with other people which inspires and motivates them to make changes towards green and sustainability.

These are the bulbs being referred to..
I posted earlier that everyone should try to get these. They save ALOT of electricity & they hardly ever have to be replaced. That is the reason I got them awhile ago. Freakin' incadescent bulbs used to die all the time on the porches. Replaced them with flourescent's & they are STILL good. It's been a few years now lol

If the rest of the world joins Australia in this simple step to sharply cut carbon emissions, the worldwide drop in electricity use would permit the closing of more than 270 coal-fired (500 megawatt) power plants. For the United States, this bulb switch would facilitate shutting down 80 coal-fired plants.

This is the BIGGEST reason to switch to them. I forget the statistic but, it's equivalent to taking many many cars off the road!

Oh come on..... This is the reason everyone was making such a big stink, ie: the ladys house was a bio-hazard after breaking one????
You have got to be kidding me!!! Also when I read that article I started thinking of all the flourescent tubes that get shattered ALL the time by kids lol TOO MUCH!!!!!

Climate change issue need to be solved at global level: UN

United Nations, May 10 (PTI): Climate change is no longer a matter of science but has become an issue which can be resolved only at an international political level, senior UN officials said.

United Nations Secretary-General Ban Ki-moon's three new special envoys pledged to use their experience from previous posts and their contacts with national leaders and other senior figures to galvanize more concerted environmental action.

The three envoys -- former Norwegian Prime Minister Gro Harlem Brundtland, former South Korean Foreign Minister and General Assembly President Han Seung-soo and former Chilean President Ricardo Lagos Escobar -- held a working luncheon yesterday with the world body chief.

In their first press conference since taking up the assignment, the three envoys said their brief from Ban was to discuss the issue with the world's major political figures, especially national leaders, and to formulate proposals ahead of the next high-level international meeting, scheduled for September with a follow-up conference in Bali this December.

"The scientific basis is now clear. Nobody needs to question the diagnosis," Brundtland said. "We know that the world is warming up, and we know that the issue is to be able to act quickly enough so that we can avoid the types of dramatic consequences that are also irreversible without sufficient action."
Echoing similar remarks, former Chilean President said, "The time for diagnosis is over. The time for action is now."

Ahhhh Crucilandia you kinda missed the point...NEVER MIND!!!!!!
I posted that to show how lame the fuel-efficiency standards ARE & going to be. My opinion the mileage should be much much higher!!

even if all US fleet were 35 mpg, it would make no difference to the CO2 in the atm.

Nothing below 50 mpg works to solve this problem.

trucks need to improve

a semi-truck gets 6 mpg (sounds like pretty good mileage to me). A load driven across the country will travel 3000 miles at 6 miles per gallon, using 500 gallons of diesel

Senate bill urges auto fuel efficiency
Published: May 9, 2007

WASHINGTON: The Senate Commerce Committee has approved a bill that would make automakers sharply increase fuel efficiency of vehicles to help cut American dependence on imported oil by the end of the next decade.

But senior Republicans said the plan was unfair to struggling U.S.-based auto companies that depend on sales of less-efficient sport utility vehicles and pickups."We need to make sure we are fair across the board to all manufacturers. There are some inherent disadvantages, especially on the truck issue," said Senator Trent Lott, Republican of Mississippi.

The proposal to reform the 30-year-old Corporate Average Fuel Economy program would require that the U.S. fleet of passenger cars and light trucks - SUVs, minivans and pickups - improve fuel efficiency by 4 percent annually. Changes would begin in 2011 and the fleet would have to average 35 miles per gallon, or 15 kilometers per liter, by 2020.

Four percent gains would be expected annually after that, but no longer-term target was set.

Light trucks must currently get 24 miles per gallon by 2011, while cars must average 27.5 miles per gallon. The truck standard was changed last year. The passenger car standard has been the same since 1990.

Members of the Commerce Committee approved an amendment barring excessive fuel price increases during a federal emergency, like a hurricane. Leading oil companies said the provision would curtail markets and harm consumers.

In the House of Representatives, the Energy and Commerce Committee is working on a similar bill, which is expected to emphasize reduced greenhouse gases and alternative fuels.

Momentum has been building in Congress for lawmakers to respond to soaring gas prices - over $3 a gallon in some areas - and address U.S. dependence on imported oil and the impact of carbon emissions on global warming.

Environmental and consumer organizations, as well as some powerful lawmakers in the Democratic-controlled Congress, say that reducing gasoline use is the quickest way to cut fuel use.

Gasoline demand accounts for nearly half of the average daily U.S. consumption of 20.9 million barrels of oil. The Senate bill, proponents say, would save 2.1 million barrels of gasoline and other auto fuel per day by 2025. That is roughly the amount of refined products the U.S. imports now.Automakers called the Senate plan unworkable, saying compliance costs alone could exceed $114 billion.

General Motors, Ford and Chrysler would bear the brunt of the costs, since their fleets have more SUVs, pickups and minivans, which get far lower gas mileage than popular sedans made by Japanese rivals like Toyota.

Ahhhh, here we go. The U.S. automakers have been pumping out these gas-guzzlers all these years while watching Toyota & Honda lead the way in efficiency. Now that they are going to have to follow, they are going to start crying poor-mouth. lol Well it's their own stupid faults if you ask me!!!!!!!!!

Well said Papis, the more companies that jump in the better, more money for research= cheaper, more efficient battery packs!!!
