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.
