Here's a graphic of Antarctic ice MELT ending in 2009 by Tedesco and Monaghan.  Note that because it is melt, the decline means that more ice is NOT melting.  
Here is the extent of sea ice in the southern hemisphere, as measured by satellite.[More]
 

The forecasts of earlier flowering and leafing are based on outdoor experiments in which plants are artificially warmed.[More]
 

Total annual releases of mercury to the atmosphere from such natural sources are about 5,200 metric tons per year.[More]
 

A team of seven scientists from various agencies in China began their article noting "In the past 100 years, the mean surface temperature in China has increased by 0.4-0.6ºC, and it is expected that the average surface temperature in western China will rise by 1.7ºC in the next 30 years and by 2.2ºC over the next 50 years." Furthermore, Xiao et al.[More]
 

On the rationale of mitigating man-made climate change and thus limiting the occurrence of extreme weather events, the U.S. Environmental Protection Agency is (unintentionally) fostering a less prepared and less resilient population. As such, EPA should regulate its own actions as endangering public health and welfare.[More]
 

Rising atmospheric carbon dioxide levels lead to an increasing amount of CO2 being dissolved in the oceans which drives down the oceans' pH level. This is often referred to as "ocean acidification" and included among the list of ills that energy production from fossil fuels imparts to the environment. Type "ocean acidification" into your Google search and you'll quickly be confronted with a litany of potential impacts-all bad.[More]
 

A team of scientists led by geochemist Zunli Lu from Syracuse University in New York state, has found that the 'Medieval Warm Period' approximately 500 to 1,000 years ago wasn't just confined to Europe.[More]
 

All we ever seem to hear about the tropical forests is that they are being destroyed, their destruction will exacerbate global warming, and on and on. You will even discover that some scientists think global warming destroyed the first tropical forests that evolved on our planet bringing rise to the dinosaurs![More]
 

A few months ago, we reported on a paper in the scientific literature (Schmittner et al. 2011) that concluded that there were only "vanishing probabilities" that the value of the earth's climate sensitivity-the amount of global temperature change resulting from a doubling of the atmospheric carbon dioxide content-was above 3.2°C, and that a climate sensitivity exceeding 6°C was "implausible." Now, a new paper has been published (Olson et al., 2012) that finds that the 95% confidence range for the value of the earth's actual climate sensitivity extends only to a value as great as 4.9°C. This is yet another in an expanding list of papers that strongly suggest that that the IPCC entertainment of the possibility that the earth's climate sensitivity is extremely high (say, greater than 5-6°C, is wrong).[More]
 

Editor's Note: The authors of the following letter, listed below, are also the signatories of "No Need to Panic About Global Warming," an op-ed that appeared in the Journal on January 27. This letter responds to criticisms of the op-ed made by Kevin Trenberth and 37 others in a letter published Feb. 1, and by Robert Byer of the American Physical Society in a letter published Feb.[More]
 

President Obama's rejection of the Keystone XL pipeline wasn't, as he claimed, based on science or the environment. It certainly wasn't based on sound economic policy, either. The decision was, in fact, the product of voodoo environomics: a destructive blend of bad science based on fear-mongering and manipulated research, the bad economics of green-job fantasies and "starve the beast" energy politics.[More]

As this time of the years reminds us, flowers never go out of style. Whether it is to celebrate a holiday or make up for some bad behavior, flowers just get it done every time. This has been the case for generations and will be the case from now until eternity.[More]
 

The articulate utility executive is nervous at the beginning of the conversation. He is groping for words -- not a common occurrence for the practiced provocateur. After all, Fritz Vahrenholt, 62, who holds a doctorate in chemistry, has been a rebel throughout his life.[More]
 

Science is all over the map on this one-and is hardly the "settled" stuff our greener friends want us to believe. One school holds that there is little-to-no detectable relationship between solar changes and surface temperatures, while another holds that there is a strong influence and that a projected period of low solar activity over the next several decades will offset much of the anthropogenic greenhouse-gas induced warming.[More]
 

Based on readings from more than 30,000 measuring stations, the data was issued last week without fanfare by the Met Office and the University of East Anglia Climatic Research Unit.[More]
 

In September, Nobel Prize-winning physicist Ivar Giaever, a supporter of President Obama in the last election, publicly resigned from the American Physical Society (APS) with a letter that begins: "I did not renew [my membership] because I cannot live with the [APS policy] statement: 'The evidence is incontrovertible: Global warming is occurring."[More]
 

We check the main predictions of the climate models against the best and latest data. Fortunately the climate models got all their major predictions wrong.[More]
 

Temperature projections for the 21st century made in the Third Assessment Report (TAR) of the United Nations Intergovernmental Panel on Climate Change (IPCC) indicate a rise of 1.4 to 5.8°C for 1990-2100. However, several independent lines of evidence suggest that the projections at the upper end of this range are not well supported..[More]

In our article, "A new, lower estimate of climate sensitivity," we described the paper-by a team led by Andreas Schmittner-in a positive light, presented and commented on the paper's main findings and conclusions, reprinted the abstract in its entirety, and included a link to where (a free version) of the paper was available at the personal website of one of the paper's co-authors (Nathan Urban).[More]
 

Texas Attorney General Greg Abbott says the rules are illegal and if imposed, will cost Texans in higher energy costs and tens of thousands of lost jobs.[More]
 

Thank you for the time and effort put forth by you and others on the InterAcademy Council in reviewing the policies and procedures of the Intergovernmental Panel on Climate Change (IPCC) and for the recommendations for change the Council has made. I hope those suggestions will be implemented and that the IPCC will become more open in its processes and in the compilation of its assessment reports. It is to this end that I wish to further address you.[More]
 

Any serious conversation about the planet's climate and our energy future must begin, paradoxically, with a backward look at geologic time. The reason for this is that the way forward is fogged by misunderstandings about the earth.[More]
