Best selections from Climate Science Forum:

“Diet, Health, and Climate Change”   (Winter 2014–15):
Healthful diets for people are better for the planet. Diets low in meat and processed foods produce less greenhouse gases than typical modern diets.

“A new normal: frequent catastrophic flooding”  (Summer 2013)

“Water on Earth: the rich get richer, as the poor get poorer”   (Summer 2012):
Where it is wet, the climate becomes wetter, with more floods; and where it is dry, the climate becomes drier, with drought more common and intense.

“Extreme weather is now more frequent”   (Winter 2011–12):
Extreme heat, drought, and heavy rainfall have clearly become more frequent. The United Nations reports that such events will likely be ever more common.

"Narwhals recruited as climate monitors in deep arctic waters"   (Autumn 2010):
The marine mammals known as “one-tooth unicorns” help scientists monitor climate change by measuring the temperature of the polar ocean all the way to the bottom.

“First time that an ozone hole formed in the Arctic”   (Winter 2011–12):
The ozone hole has appeared every year over Antarctica, but in 2011 another such hole formed in the Arctic. How did conditions in the North allow that?

"Increasing drought now limits global water cycle"   (Autumn 2010):
Evaporation from the land is now declining, not increasing, as would be expected on a warming Earth. Is there now less water available on the continents?

“Does smoke offset the CO2 greenhouse effect?”   (Autumn 2009):
New research has swept away the murk on how airborne particles change global climate.

“Large part of climate change deemed irreversible”  (Spring 2009):
Global temperatures will remain elevated even after all carbon dioxide emissions cease, says Susan Solomon, who co-discovered the ozone hole.

“What climate prediction models still cannot do: an expert speaks out”  (Summer 2002): Climate models still do not get the regional details correct, although humans respond to regional climate, not global climate. An interview with Bob Livezey, senior scientist of the US Climate Prediction Center.

“Fair warning? . . . how arctic climate change has rapidly freshened deep Atlantic waters”    (Summer 2002)  

“Air temperature varied in sync with greenhouse gases through four ice ages and warm spells”     (Autumn 2002): Both methane and CO2 increased in sync with global-scale warming at the times when four Ice Ages ended over the last 420,000 years.

“Earth is warmer: has the atmosphere warmed too?”    (Winter 2004):
It had been devilishly difficult to reconcile the climatic temperature changes observed by balloons with the changes observed by satellites. The reasons are now clear.
