The first new all-time national temperature record of 2012 belongs to Morocco, thanks to the 121.3°F (49.6°C) temperature measured at Marrakech on July 17, 2012. According to the Wunderground International Records data base maintained by our weather historian, Christopher C. Burt, the previous record was 120.4°F (49.1°C) at Agadir on July 30, 2009. A hotter temperature of 51.7°C (125.1°F) was reported from Aghadir (Agadir) Souss Massa Dra region on 17 August 1940 during a chergui wind event. However, this reading is considered unreliable by weather records researcher Maximiliano Herrera, since the temperature was 6°C higher than that measured at nearby stations.

Seven nations set all time heat records in 2011. Nineteen nations (plus the the U.K.'s Ascension Island) set all-time extreme heat records in 2010. One nation (Zambia, in 2011) set an all-time cold record during the period 2010 - 2012. With a very hot airmass in place over much of North Africa, the Middle East, and Western Asia the remainder of this week, more all-time national heat records may fall.


Figure 1. A sample image of what the new Fire Risk layer on our wundermap looks like. This is the Keetch-Byram Drought Index, one of several indices that can be used to measure fire risk. Blue and green colors represent lower risks, while yellow and orange colors show higher risk. The highest risk is shown in dark red. The legend for the Fire Risk layer explains that these highest risk areas are often associated with more severe drought with increased wildfire occurrence. Intense, deep burning fires with significant downwind spotting can be expected. Live fuels can also be expected to burn actively at these levels.

Wunderground releases new fire risk layer on its wundermap
Our interactive wundermap, which allows one to overlay multiple meteorological data sets, has a new layer: a Fire Risk layer. Using data from the U.S. Forest Service's Wildland Fire Assessment System, we give you option to plot up U.S. fire danger using a variety of options: Fire Danger Rating, Lower Atmosphere Stability (Haines Index), Keetch-Byram Drought Index, 10-hr Dead Fuel Moisture, 100-hr Dead Fuel Moisture, and 1000-hr Dead Fuel Moisture. According to the National Interagency Fire Center, California currently has the most number of of large fires burning of any state (5), which makes sense, given what the fire risk map above is showing.

It's hard to have a reasonable debate when one side of the team denies facts. It's like fighting a losing war.

I now either see them, the deniers, as trolls or people with extremely hard heads and I will just ignore them because debating never goes anywhere most of the time...

Discussion brings clarity, and I enjoy it immensely.

But to dismiss AGW as a theory holds lil water.

Esp to folks like the Carteret Islands who have to move to Bouganville as the sea claims their Home.

Thanks for the discussion, Pat and Neapolitan. I think a good discussion like this one is educational. Ones filled with venom that occur here often are less educational since most turn away.

Let me be clear and state that I believe in AGW. I was just stating that technically it's still a theory. However, there are facts within the theory that cannot be denied, such as the ones Pat and Nea showed.

FLASH FLOOD Hiking out of Havasupai



Excellent vid on the dangers of flash flooding. In places with rocky or desert terrain the storm that dumped the rain can very far away, you'd never know it's coming until the moment it hits you. This is why you never camp out in a creek bed, and why you keep a close eye on your kids in places like this.

That's a good point. However, it's not only non-scientists that are against AGW theory. I know, the majority are pro-AGW and for good reason.

...STRONG TO SEVERE THUNDERSTORMS EXPECTED THIS AFTERNOON...

A STRONG COLD FRONT WILL PUSH SOUTH ACROSS THE AREA THIS AFTERNOON.
THE HEAT AND HUMIDITY OF THE PAST SEVERAL DAYS HAS CREATED A VERY
UNSTABLE ATMOSPHERE ACROSS THE REGION...AND THIS WILL LEAD TO THE
DEVELOPMENT OF WIDESPREAD THUNDERSTORMS BY EARLY THIS AFTERNOON.

THE FIRST AREAS TO SEE THUNDERSTORM DEVELOPMENT WILL BE ACROSS FAR
NORTHERN NEW JERSEY AND THE LOWER HUDSON VALLEY...BEGINNING AROUND
NOON OR 1 PM. THESE STORMS WILL THEN MOVE FAIRLY QUICKLY TO THE
SOUTHEAST...REACHING NEW YORK CITY AND COASTAL LOCATIONS BETWEEN 2
PM AND 4 PM BEFORE MOVING OFFSHORE BY EARLY THIS EVENING.

SOME OF THESE STORMS WILL BE SEVERE...WITH DAMAGING WINDS IN EXCESS
OF 60 MPH AND LARGE HAIL. FLASH FLOODING IS ALSO POSSIBLE AS THE
MOIST ATMOSPHERE WILL ALLOW THESE STORMS TO PRODUCE 1 TO 2 INCHES OF
RAINFALL IN A SHORT AMOUNT OF TIME. FREQUENT CLOUD TO GROUND
LIGHTNING IS ALSO EXPECTED.

STAY TUNED TO NOAA WEATHER RADIO AND LOCAL MEDIA OUTLETS FOR THE
LATEST INFORMATION.

Global Climate Change Indicators
National Oceanic and Atmospheric Administration
National Climatic Data Center



Many lines of scientific evidence show the Earth's climate is changing. This page presents the latest information from several independent measures of observed climate change that illustrate an overwhelmingly compelling story of a planet that is undergoing global warming.
It is worth noting that increasing global temperature is only one element of observed global climate change. Precipitation patterns are also changing; storms and other extremes are changing as well.

How do we know the Earth's climate is warming?

Thousands of land and ocean temperature measurements are recorded each day around the globe. This includes measurements from climate reference stations, weather stations, ships, buoys and autonomous gliders in the oceans.
These surface measurements are also supplemented with satellite measurements. These measurements are processed, examined for random and systematic errors, and then finally combined to produce a time series of global average temperature change.
A number of agencies around the world have produced datasets of global-scale changes in surface temperature using different techniques to process the data and remove measurement errors that could lead to false interpretations of temperature trends.

The warming trend that is apparent in all of the independent methods of calculating global temperature change is also confirmed by other independent observations, such as the melting of mountain glaciers on every continent, reductions in the extent of snow cover, earlier blooming of plants in spring, a shorter ice season on lakes and rivers, ocean heat content, reduced arctic sea ice, and rising sea levels.


That says nothing about AGW, which as I said, is still a theory.

Here are the facts:

1) The planet is warming and the climate is changing at an increasing rate.

2) The only possible cause that's been found for most of that warming after millions of man-hours looking into the issue is increasing concentrations of atmospheric CO2.

3) We humans are pumping about 40 trillion liters a day of CO2 into the environment, mostly from the burning of fossil fuels.

Global warming is not an election issue because the streets of Manhattan are not flooding yet. Both political parties are painfully weak on issues that involve change. Master's blog has been about global climate change most of the time, so I don't see how talking about the miserable state of the political side of that is inappropriate here. I don't blame it on one party or another. It's just pathetic.


It's just mystifying to me that this isn't a larger issue. Having met a few politicians I believe they are mostly 'furbo' (a particular flavor of clever than doesn't preclude stupid) and some are really intelligent. I can't see how, between politicians who care and all the other 'leaders' in this country, no one is standing up and screaming. It's not just liberals anymore, it is the CIA, most large companies (including oil companies), teh Defense Dept, most other government departments, etc. >> everyone is planning for survival in a globally warming world and no one is forcing the issue out into the open politically.

Climate change is weather. So is the state of the ice cap and human impact. You can't talk about the cause of a hurricane without talking about the larger cycles. Lack of political will is directly related to the drought around the world.

16th-19th. Wet system from Gulf of Mexico moves inland and brings copious rains to eastern Mississippi River Valley.

they give the SE a lot of rain the next few months, might get rid of the drought.
No floods like 2009 hopefully.
