It's always something: crops to blame for increased annual variation of CO2
From the University of Wisconsin-Madison @UWMadScience Crops play a major role in the annual CO2 cycle increase MADISON, Wis. — Each year, the planet balances its budget. The carbon dioxide…
Who needs an Orbiting Carbon Observatory to track it when you can model Carbon Dioxide movement?
Video follows. I had at first thought that this press release from NASA Goddard was telling me that they had taken the data from their new Orbiting Carbon Observatory and…

Guest Post by Willis Eschenbach I greatly enjoy reading old science. Back fifty years or more ago, they actually did real science, not the “my model says it must be…
Another major misunderstood climate issue – models ‘underplay plant CO2 absorption’
Global climate models have underestimated the amount of CO2 being absorbed by plants, according to new research. Scientists say that between 1901 and 2010, living things absorbed 16% more of…
Claim: Arctic sea ice helps remove CO2 from the atmosphere
From the University of Southern Denmark. This is a bit of a surprise, and may well be true, but I’m not too keen on the first couple of paragraphs. Summer…

BOMBSHELL: Study shows greenhouse gas induced warming dropped for the past 14 years
Paper finds a decrease of IR radiation from greenhouse gases over past 14 years, contradicts expected increase – cloudiness blamed for difference. A paper published in the Journal of Climate…
CO2 data might fit the IPCC hypothesis, but it doesn't fit reality
Opinion by Dr. Tim Ball I have no data yet. It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories,…
