Arctic Warming Pushing Winter Weather South


Meteorologist David Eichorn with the State University of New York’s College of Environmental Science and Forestry (SUNY-ESF) discusses how warming around Earth’s northern pole can push winter weather further south resulting in colder temperatures across the Northeastern and Eastern United States.

The Extreme Weather of 2010


Extreme Weather Events Felt Around the World in 2010 While no single weather event can be definitively traced to global climate change, we would expect to see a greater number of extreme weather events accompanying climatic shifts. As more water vapor enters the atmosphere with rising global temperatures, large-scale precipitation events become more commonplace resulting … Continue reading

Should The Earth Be Cooling?


Current Climate Running Against the Grain When considering whether or not the human influence on the Earth’s climate is discernible, one of the immediate questions that comes to mind is, “What would the climate be doing in the absence of human interference?” Indeed all climate models strive to identify the impact of natural mechanisms as … Continue reading

Global Cooling? Pick a Time, Any Time.


Satellite Record Now Shows Warming Across All Date Ranges I don’t think that anyone disagrees with the fact that we actually are in the middle of a cold period that started about nine years ago. Now that’s not me talking. Those are the scientists who say that. – U.S. Senator James Inhofe, July 23, 2010 … Continue reading

Did You Know? – Non-Greenhouse Gases in the Atmosphere


Nitrogen (78%) and oxygen (21%) which comprise over 99% of the dry atmosphere, are not greenhouse gases and do not contribute to the Earth’s greenhouse effect.

State of the Climate, Indicators of Change


As the United Nations Climate Change Conference in Copenhagen gets into full swing, it’s a good time to take a look around and assess the current state of things. In the 30 years of direct satellite observation… Solar irradiance has declined (Source: PMOD/WRC) which should drive temperatures down, and we are currently in the middle … Continue reading

Study Predicts Fewer, Stronger Atlantic Hurricanes in Warming World


A study published in the journal Nature Geoscience used a combination of computer models to simulate future climate conditions in the Atlantic ocean basin and its related hurricane activity. One result of the models was a decrease in the number of hurricanes and tropical storms expected in that area through the end of the twenty-first … Continue reading

No Warming Since 1998 – Old Claim Given New Life


A recent article by the BBC has given new life to an old myth. The article references conclusions from the UN’s World Meteorlogical Organization that the La Nina conditions responsible for a colder winter will continue through a large portion of the year, resulting in cooler temperatures. This conclusion along with a convenient timeframe has … Continue reading

New Study Challenges Cosmic Ray Theory


Those skeptical of the theory of anthropogenic global warming often point to the sun as the source of modern era planetary warming. The reasoning is two-pronged. The argument goes that increases in solar activity increase the amount of heat received by the Earth. However, as this is insufficient to explain the recent warming trend, this … Continue reading

A Closer Look: CO2 Lagging Temperature


Don’t increases in temperature lead to increases in CO2, not the other way around? Yes and no. Increases in global temperature can lead to an increase in atmospheric levels of CO2. However, as CO2 is added to the atmosphere, it traps additional heat causing a further rise in global temperatures. Source: U.S. EPA As you … Continue reading
