First Time
that an Ozone Hole Formed in the Arctic
(Winter 2011–12):
The ozone hole has appeared every year over
the Antarctic, but in 2011 another such hole formed over the
Arctic. How did conditions in the North allow that?
Extreme Weather
is Now More Frequent (Winter
2011–12):
Extreme heat and drought, and heavy rainfall
have clearly become more frequent. The United Nations reported
that such events will likely be ever more common in this century.
"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.
The Recent
La Niña Winter of 2010–2011
(Spring 2011)
"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 less water available on the continents?
Does
Smoke or Smog 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):
Susan Solomon (co-discoverer of
the ozone hole) asserts temperatures will remain elevated
& stable, even after all emissions of carbon dioxide cease.
Arctic
Ice Reaches a Record Low Extent
(Summer
2007):
The ice pack on the Arctic Ocean shrunk to
the smallest area ever observed in 2007. That area was 39%
less than the long-term average.
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 in NOAA.
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 when all four Ice Ages ended, during 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
those observed by satellites. The reasons are now clear.
Ocean
Warming said to Confirm Earths Energy Imbalance
(Spring 2005):
The massive amount of water in the oceans delays the warming
of the planet, but also delays the planet's response to any
future change in the amount of greenhouse gases.
