Heat generated in major metropolitan areas is altering the character of the jet stream and other atmospheric systems, at times affecting the weather thousands of miles away, a new study says.
Here’s an article by Peter Lehner, Executive Director of the Natural Resources Defense Council (NRDC), who writes on the levels of air pollution in Beijing, which last week reached a level of 755–on a scale of 0 to 500 (the scale on which our Environmental Protection Agency here in the U.S. rates anything over 300 as “hazardous.”) The Internet is littered with (more…)
When global warming is discussed, many will try to predict how much the ice cap will melt and how much the seas will rise. There are many variables in this calculation. A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where (more…)
Here’s an article that’s illustrates what happens when regulators get clever in creating incentives for environmental stewardship and responsibility: smart people work around them, unintended consequences result, and windfall profits occur in random places that have nothing to do with environmental benefit.
If I were doing this, I’d make the whole situation (more…)
President Anote Tong has a problem. He leads a country which is very seriously threatened by climate change. The incursion of sea water into the islands’ drinking water is real and as most of the coral atolls are only a few metres above sea level, a rise in sea level means the end of the country.
So what do you do? Clearly trying to persuade the (more…)
In his second inaugural address, President Obama prominently cited the need to tackle climate change, a vow Democrats say the president will carry out using his executive powers to bypass Congress.
After barely addressing the issue during his reelection campaign, Obama on Monday indicated that climate would be a priority in his second term, saying that failure to address the threat of a changing climate “would betray our children and future generations.” “Some may still deny the overwhelming judgment of science,” Obama said. “But none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms.”
According to a New York Times report, the president’s new climate strategy will include tougher Environmental Protection Agency rules on emissions from coal plants, as well as stricter energy standards for home appliances and buildings.

I come across several articles each day that cause me to adjust my position on where we’re going as a civilization. Here’s one on BP, peak oil, and climate change that offers an interesting nuance, concluding with the following:
NASA’s Terra satellite acquired natural-color images of northeastern China on January 3 and January 14, highlighting a drastic shift in air quality for the region.
According to the images, the opaque, gray areas are clouds or fog, which are saturated with a gray or yellow tint as a result from the air pollution. (more…)
Large amounts of ozone — around 50% more than predicted by the world’s state-of-the-art climate models — are being destroyed in the lower atmosphere over the tropical Atlantic Ocean. A team of scientists from the National Center for Atmospheric Science and the Universities of York and Leeds made the discovery, which is significant (more…)
