Save the Keeling Curve!

Climate change's most iconic research project is in danger--a victim of budget cuts in an era of increased government belt-tightening. The Keeling Curve is a measurement of the concentration of carbon dioxide in the atmosphere made atop Hawaii’s Mauna Loa, begun in 1958 by Dr. Charles Keeling. It is the longest-running such measurement in the world. The curve was instrumental in showing how human emissions of carbon dioxide were steadily accumulating in Earth's atmosphere, and raised awareness that human-caused climate change was an ever-increasing threat to the stability of our climate. After Keeling's death in 2005, the measurements were continued by his son, Ralph F. Keeling. Support from NSF, NOAA and NASA is being diminished or withdrawn, and Keeling has turned to crowd-funding to help raise funds to continue these important measurements. I hope you can join me in making a donation.


Figure 1. The Keeling Curve: climate change's most iconic image. The curve's steady year-by-year increase in CO2 due to burning of coal, oil, and natural gas has wriggles on top of it, due to the natural seasonal cycle in CO2--plants suck in CO2 during the Northern Hemisphere growing season, then release it during the winter.

CO2 Levels Hit 401 ppm
The latest data from the Keeling curve website shows that atmospheric carbon dioxide levels are surging upwards in their usual late winter push, as plants return CO2 to the atmosphere before the Northern Hemisphere spring growing season hits. CO2 levels reached 401 ppm (parts per million) last week on top of Mauna Loa, setting a new record. CO2 levels were at 280 ppm in 1870, increased less than 1 ppm per year in the 1960s, then accelerated to 2 ppm per year during the 2000s. Less than 1% of the increase since 1870 has been due to natural sources, such as volcanoes. The last time carbon dioxide levels reached 400 ppm—between 2.5 and 5 million years ago during the Pliocene Era—the Earth was 3.5 to 9° F warmer (2 to 5° C), and sea levels were 65 to 80 feet higher.

Senate holds all-nighter on climate change
A group of 31 U.S. Senators pulled an all-nighter last night on the floor of the U.S. Senate, taking turns from 9 pm Monday night until 9 am Tuesday morning to promote policy actions on climate change. Many of the Senators involved issued tweets using the hashtag #Up4Climate. The all-nighter was another indication that politicians are becoming increasingly bold about speaking up on climate change.

Latest Version of our WunderMap App Now Includes WunderPhotos
Weather Underground has released today a new version of our WunderMap app for iPhone and iPad. The main new feature that we'd like to highlight is the WunderPhotos layer--now users can view, share, and submit photos all from within the app. Here are a few of the features of the new version of the WunderMap app:

◦ Improved Weather Station display, and both station size and station spacing are now adjustable (Weather Stations Layer ⇒ Settings).
◦ New WunderPhotos layer! View, share, and submit beautiful weather photos.
◦ Fixed incorrect elevation for some Personal Weather Stations.
◦ Swipe-to-delete search history items.
◦ "Terrain/Satellite” and other map options made more prominent.
◦ Bug fixes (crashes, visual glitches, and usability enhancements).
◦ Optimized performance across all devices.


The latest version is available to download for iPhone and iPad at https://itunes.apple.com/app/wundermap/id364884105?mt=8.

Good morning everyone, I was just wondering about people thoughts on the up coming Hurricane Season. Does it seem like it's going to be a quite one? I've been sitting back reading all winter like usual and just wondering about everyones opinion.

Thank you,

I'm thinking it is going to be less active than normal, due to the el nino that is forecast to come during the summer, which causes strong upper level winds to head across the Caribbean. This causes unfavorable wind shear that limits tropical cyclone development.


My numbers this year?

I'm going for about 10-2-1.

To illustrate, the long-term trend in carbon isotope ratio (13C/12C) of the CO2 is absolutely diagnostic of the atmospheric combustion of 12C-rich fossil biological carbon:

This is exactly why climate scientists have no credibility. The Keeling curve does NOT demonstrate the rise in global CO2 levels due to humans. It ONLY shows the rise in global CO2. There's a distinct difference.

Global CO2 levels can rise for a variety of reasons unrelated to humans. Volcanoes and fires come to mind as two. Before you can pin it on humans you have to subtract out naturally occuring sources.

Geez!

It rises and falls in an annual cycle, and volcanoes contribute negligible amounts. At least get acquainted with the subject before you make your ham fisted attempts at trolling.

The most interesting piece of the puzzle on the Malaysia flight per a expert on TV last night (and if this verifies) is his initial information that the transponder was "turned off" manually at some point even though military tracking indicated that the plane turned around.%uFFFD That means that someone in the cockpit (whether crew or third party) did not want the plane tracked for whatever reason.%uFFFD Only way to confirm what happened in the cockpit will be to recover the flight recorders at some point.

This is going to take a very long time if the wreckage is ever found.


You saw the samething I did on MSNBC at about 11pm last night. Also the guy said that the plane possibly went hundreds of miles off course possibly over the Indian Ocean.

Quoting 520. StormWx:


There are lots of possibilities Scott, one of them being a hijacking. Others being a mechanical malfunction where all the onboard systems failed, to even being hit by a meteor as silly as it sounds. The fact that they dont even know where to looks means that all possibilities are open and that nobody knows for sure what happened. If the plane went off course the pilots could have very well tried to go back to land at a location where they have knowledge. We may never know unless we find that little box at the bottom of what appears to be the ocean...somewhere.

Meanwhile, same story for next week, temperature wise across the US.

or it could be just a pilot gone apes. he could of locked himself in and took them for a ride almost like forecasting the upcoming hurricane season. no clue

I think they (Malaysia) don't have a clue....

- Mystery object -
Malaysian air force chief General Rodzali Daud attempted to explain why the search zone had been expanded, telling the press conference that military radar detected an unidentified object early Saturday north of the Malacca Strait off Malaysia's west coast.
He said that the reading, taken less than an hour after the plane lost contact over the South China Sea, was still being investigated and they were not able to confirm it was MH370.

Woke to rain and heavy fog this AM mile south of Oneida Lake, NY. Last half hour has turned to large wet snowflakes. Seems the snow has started a little earlier than was thought here, so mayhap we end up on the higher end of the expected range. Peace out Friends.

If it did turn around, it had enough fuel to make it to Antarctica. Just sayin'.

Good Morning. Snowing at the moment around the Eastern Great Lakes and extreme NE portions of the US. Here are the current temps. Not as strong polar-votexy as recent systems (we are going into March) but most of the mid-sections of Conus are still in the grips of Winter:

Interesting information coming out over the last 24hrs in regards to this missing plane. Apparently all communication was cut off inside the cockpit long before the plane went missing leading to the possibility that the cockpit was taken over. What is strange though if this indeed is terrorism then why hasn't anybody taken claim for this.

LOL! I feel kinda bad for inland regions stuck in fog...big storms cease and then oh great, fog! I got the back garden cleaned up from all the storms yesterday and house tidied a bit (big deal for me as I have a great aversion to housework LOL) so today will be for getting some photos and hopefully do some star trails tonight. Too bright of a Moon for Milky Way sadly though.

Largo, all the best and hope no problems with the surgery!

Looking at towering cumulus clouds coming in from the west right now. Looks like it is going to get stormy here soon. I hope my buddy Largo is OK and I made sure to pray for a speedy recovery for him.



Looks like a few thundershowers will come through your area this morning. There's been a few lightning strikes off to your West. I think it should be cleared before any daytime heating can energize the storms to a strong or severe level.

We got only light rain here in the Tampa area. Heavier stuff to our north.
