Global Temperatures

Sobering numbers from the International Energy Agency. IEA's estimates for global carbon dioxide (CO2) emissions in 2011 are in. Draw your own conclusions.

In other words, just as cold winter in the U.S. during the previous two years did not mean that it was cold globally, a warm U.S. winter this year didn't mean that it was warm globally.

Does a new study lend support to Richard Lindzen's "iris effect" hypothesis?

Last month was the fourth warmest January on record for the contiguous United States and the 19th warmest January on record globally. This 19th warmest ranking also means that January was the "coolest" month in the past four years.

While the United States has had a relatively mild winter to date, the winter has been exceptionally harsh in much of Europe, especially Eastern Europe in recent weeks. What does all of this say about global temperatures?

I guarantee that most scientists, myself included, would love to make their reputation by refuting the whole notion of global warming. We have tried and have concluded that we can't.

The La Niña, combined with another weather phenomenon, the North Atlantic Oscillation, resulted in bouts of extreme cold in the U.S. last winter, and there are signs that very cold air will move southward into the U.S. during the next couple of weeks.

The big weather story of October was a cold event. A major and, in some cases, record-breaking snow storm resulted in the 14th billion-dollar-plus weather event of the year.

I wouldn't hold my breath waiting for a Congressional resolution marking the end of climate skepticism -- or the beginning of major climate legislation -- any time soon.

A special report from the International Energy Agency released in advance of the World Energy Outlook 2011 examines how ramping up natural gas would impact energy and climate up to 2035.

Fox News called the three-and-a-half-minute segment "Climate Change Myths: Separating Fact From Fiction" -- an apt name because as far as the science is concerned, there's very little that could be characterized as fact, and a whole lot that could pass for fiction.

WASHINGTON — The government's monthly climate report is beginning to sound like a broken record. The National Climate Data Center reported Monday...

The National Oceanic and Atmospheric Administration's data show clearly that the Earth has been heating up over the past 130 years, and especially over the past 30 years.

Scientists call it DAI -- "dangerous anthropogenic interference" with the climate system. The United States along with 191 other countries pledged to ...
