Research Suggests Climate Models Underestimate Climate Sensitivity

Climate models are wrong? Climate models are mathematical representation of an enormously complex system. They are intended to project trends, not predict events. They are an imperfect but indispensable tool to gain an understanding of what we can likely expect in the future. Casting doubt on the reliability of climate models is a common theme among […]Read More

CO2 Levels Reach and Maintain 400 PPM – A Dubious

The World Meteorological Organization reports that, for the first time in human history, atmospheric concentrations of carbon dioxide (CO2) eclipsed 400 parts-per-million (ppm) in the northern hemisphere for the entire month of April.CO2 concentration varies with the seasons, generally reaching their highest level early in the northern hemisphere’s spring before seasonal intake of CO2 from vegetation. The […]Read More

Shocking New NASA Report Shows CO2 Cools the Atmosphere: Anatomy

Science is so hard… A recent post on our Facebook page claims there is a “new study” showing that carbon dioxide acts as a coolant in the atmosphere. Our Facebook poster, we’ll call him “Adam” (because that’s his name), is confident he’s unearthed this new pearl of knowledge that blows centuries of science on CO2 aside. […]Read More

Video Friday: Temperature Leads CO2? The 800-Year Lag

Potholer54 (a.k.a Peter Hadfield) tackles a common myth about climate change often called the “800-year lag.”  Antarctic ice core data shows CO2 lagging temperature during periods of deglaciation; this has been well understood for decades. Despite this, many climate change “skeptics” ignore the full picture of numerous studies over the years and assert these data of […]Read More

COP 18: Bridging the Gulf between Science and Reality

In theory the slew of recent climate studies should inspire the delegates that have assembled for the 18th Conference of the Parties (COP 18). In practice the 194 nations that are meeting in Doha, Qatar, are getting bogged down by the same old arguments. The consensus once again this year appears to be that nothing will […]Read More

EarthTalk: Atmospheric CO2 – Is it Too Late Anyway?

EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine Dear EarthTalk: I read that CO2 in our atmosphere is now more than 300 parts per million. Doesn’t this mean that we’re too late to avoid the worst impacts of climate change?  — Karl Bren, Richmond, VA […]Read More
