New climate study is frenemy of climate science driven policy
Posted by Greg Laden on April 6, 2016 
There is a new study out in Nature that is liable to be misinterpreted, or that may be flawed in a way that lends itself to misuse, in the context of climate science driven policy. The study is “Northern Hemisphere hydroclimate variability over the past twelve centuries” by Fredrik Charpentier Ljungqvist, Paul J. Krusic, Hanna…

People finally concerned about climate change
Posted by Greg Laden on March 18, 2016 
Though not enough. And for the wrong reasons. But this is still good news. Somewhere around 1990, but you could justify an earlier date if you like, science knew enough about global warming, the increase in the planet’s surface temperatures caused by human release of greenhouse gas pollution and other human effects, to have initiated…

Lamar Smith Gets It Wrong #FauxPause
Posted by Greg Laden on March 3, 2016 
There wasn’t a “pause” in global warming. The rate at which the plant’s surface warms because of human greenhouse gas pollution varies over time. Sometimes the warming is quicker, sometimes it is slower. There are multiple reasons for a temporary slowdown in the temerature curve, including the temperature curve being a little inaccurate, the ocean…

Are we witnessing an Arctic Sea meltdown, right now?
Posted by Greg Laden on February 24, 2016 
The Arctic Sea freezes over. The Arctic Sea melts. This happens every year. The average date for the maximum extent of Arctic Sea ice, based on a period of 1981-2010, is March 12. The minimum extent is reached, on average, about September 15h. Every year for the last several years, the minimum ice has been…
What is the “pause” in global warming?
Posted by Greg Laden on February 24, 2016 
A new paper (commentary) on the so-called “pause in global warming” puts it all together. First let’s establish this as a starting point. When climate science contrarians refer to a “pause” or “hiatus” in global warming, they usually mean that the process of warming of the Earth’s surface caused by the human release of greenhouse…
