Sir Ken makes many good points — some you may not agree with — but he certainly is not saying that math and science should be taught or studied less, rather that music and the arts and creativity in general should be pursued more.

Greenland's ice cap, which covers more than 80 percent of the island, is melting faster than expected because of global warming, a Danish researcher said on Monday.

September 23 this year marks an unfortunate milestone: the day humanity will have used all the resources nature will generate this year, according to Global Footprint Network data. Earth Overshoot Day marks the day when humanity beings living beyond its ecological means. Beyond that day, we move into the ecological equivalent of deficit spending, utilizing resources at a rate faster than what the planet can regenerate in a calendar year. Globally, we now now require the equivalent of 1.4 planets to support our lifestyles. But of course, we only have one Earth. The result is that our supply of natural resources -- like trees and fish -- continues to shrink, while our waste, primarily carbon dioxide, accumulates.

He states, "our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century."[3][4] In June 2008 Stern increased the estimate to 2% of GDP to account for faster than expected climate change.[5]

Every day for the last 112 years, people have trekked up the same gray outcropping to dutifully record temperatures and weather conditions. In the process, they have compiled a remarkable data collection that has become a climatological treasure chest.

Its conclusion is that temperature increased and decreased a little over the centuries, but the fluctuations were small enough that the line was roughly flat, like the shaft of a horizontal hockey stick. Then, from about 1980 to now, temperature increased sharply, more than any increase before — like the blade of the hockey stick. For the past 10 years, climate-change skeptics have been calling the hockey stick bogus. Now the scientists who studied the climate record and produced the original hockey-stick graph have done a new study using more data from more sources — and they got the same pattern.

GeoEye-1, designed and built by General Dynamics Advanced Information Systems, is the world's highest resolution commercial imaging satellite. Designed to take color images of the Earth from 423 miles (681 kilometers) in space and moving at a speed of about four-and-a-half miles (seven kilometers) per second, the satellite will make 15 earth orbits per day and collect imagery with its ITT-built imaging system that can distinguish objects on the Earth's surface as small as 0.41-meters (16 inches) in size in the panchromatic (black and white) mode. The 4,300-pound satellite will also be able to collect multispectral or color imagery at 1.65-meter ground resolution. While the satellite will be able to collect imagery at 0.41-meters, GeoEye's operating license from NOAA requires re-sampling the imagery to half-meter resolution for all customers not explicitly granted a waiver by the U.S. Government.

EX Many extremes and their associated impacts are now changing. For example, in recent decades most of North America has been experiencing more unusually hot days and nights, fewer unusually cold days and nights, and fewer frost days. Heavy downpours have become more frequent and intense. Droughts are becoming more severe in some regions, though there are no clear trends for North America as a whole. The power and frequency of Atlantic hurricanes have increased substantially in recent decades, though North American mainland land-falling hurricanes do not appear to have increased over the past century. Outside the tropics, storm tracks are shifting northward and the strongest storms are becoming even stronger.

In northern Greenland, a part of the Arctic that had seemed immune from global warming, new satellite images show a growing giant crack and an 11-square-mile chunk of ice hemorrhaging off a major glacier, scientists said Thursday.

Data from the UK Met Office shows that temperatures in the first half of the year have been more than 0.1 Celsius cooler than any year since 2000. The principal reason is La Nina, part of the natural cycle that also includes El Nino, which cools the globe. Even so, 2008 is set to be about the 10th warmest year since 1850, and Met Office scientists say temperatures will rise again as La Nina conditions ease.

There's been a lot of pressure lately to open up protected areas for oil drilling. But common sense says drilling is not the answer. Switching is.
