Health, and Climate Change
Healthful diets for people are better for the planet. Diets
low in meat and processed foods produce less greenhouse gases
than typical modern diets.

on Earth: the rich get richer, as the poor get poorer
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 heat, drought, and heavy rainfall
have clearly become more frequent. The United Nations reports
that such events will likely be ever more common.

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
time that an ozone hole formed in the Arctic
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?

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?

New research has swept away the murk on how
airborne particles change global climate.

Global temperatures will remain
elevated even after all carbon dioxide emissions cease, says
Susan Solomon, who co-discovered the ozone hole.
prediction models still cannot do: an expert speaks out
Climate models still do not get the regional details correct,
although humans respond to regional climate, not global climate.

the US Climate Prediction Center.

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.
