Introduction
Today’s generation of climate models are typically run at resolutions that cover the globe with a 256 by 128 longitude/latitude horizontal grid or about a 1.4 degree latitude-longitude grid at the equator.
An experimental version of the CCSM CAM3 was run at a resolution much more similar to a global numerical weather prediction model (1024×512 grid [...]

Global climate change … NASA’s eyes on the Earth: A warming world – global temperature update … piecing together the temperature puzzle.
Each year, scientists at NASA’S Goddard Institute for Space Studies analyze global [...]
In the past few decades, the annual average Arctic temperature has increased at almost twice the rate as that of the rest of the world. Evidence of this warming can be seen in the widespread melting of glaciers and sea ice, shortening of the snow season, rising sea level, melting of the permafrost, and other [...]

(CNSNEws.com) – Which is it–6 feet or 3.5 feet?
Last week, White House science czar John Holdren told members of the House Select Committee on Energy Independence and Global Warming that changes in global temperatures could mean a rise in sea levels of 6 feet or more in a century.
But Joan Lubchenco, administrator of the National [...]
The animation depicts the surface temperature increase (relative to the 1870-1899 period) from the average of a set of CCSM3 experiments of the IPCC AR4 SRES A1B (midrange) climate change scenario. The lower panel shows the global average temperature change from the same base period.

The last decade has been measured as the hottest on record all around the globe. This overall result is derived from a patchwork of readings with widely varying effects on local climates. Scientists agree that the change is being spurred by rising levels of carbon dioxide in the atmosphere. This clip was produced by NASA’s [...]
Al Gore – Reflecting on Climate Change and Global Warming
I invite you to take 10 minutes to reflect on climate change and Global Warming. Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans in recent decades and its projected continuation. Global average air temperature near the Earth’s surface [...]
When you have -80 F average on Mars and 95% CO2 you may think to ask for some footprint carbon taxes on martians. Leaving the joke aside – If Earth’s distance from Sun is 1 AU, Mars will be 1.524 AU from Sun and Venus 0.723 AU from Sun. So Venus is much closer to [...]
The globe is warming, but is it really all our fault? And is it true the debate is over? No. What you think you know may not be so. Over the next 100 years, sea levels are expected to rise seven to 24 inches, not 20 feet says the IPCC. Polar bears appear to be [...]

Climate change is a change in the statistical distribution of weather over periods of time that range from decades to millions of years. It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). [...]
