Obituary: Dr. Burt Bolin, Pioneer Climate Scientist

————————————————
“The greatest disturbances of which we are aware are
those now being introduced by man himself. Since his
tampering with the biological and geochemical balances
may ultimately prove injurious — even fatal — to himself,
he must understand them better than today.”

OBITUARY
Bert Bolin (1925-2008)
Pioneering climate scientist and communicator.

As the first chair of the Intergovernmental Panel
on Climate Change (IPCC), and one of the first
scientists to understand the environmental impact
of carbon dioxide produced by human activities,
Bert Bolin left an indelible mark. A pioneer of
climate science, he died in Stockholm on 30
December 2007, aged 82.

Bolin was born in Nyköping, Sweden, on 15 May
1925. He completed his PhD at the University of
Stockholm in 1956, and was within five years
professor of meteorology there – a post he held
until his retirement in 1990. During that time,
he published more than 160 papers related to the
meteorology and chemistry of the atmosphere,
contributing to an improved understanding of
numerical weather models and acid deposition.

Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through
Emissions from Land Use Change

Abstract
Most prior studies have found that substituting biofuels for gasoline
will reduce greenhouse gases because biofuels sequester carbon
through the growth of the feedstock. These analyses have failed to
count the carbon emissions that occur as farmers worldwide respond to
higher prices and convert forest and grassland to new cropland to
replace the grain (or cropland) diverted to biofuels. Using a
worldwide agricultural model to estimate emissions from land use
change, we found that corn-based ethanol, instead of producing a 20%
savings, nearly doubles greenhouse emissions over 30 years and
increases greenhouse gases for 167 years. Biofuels from switchgrass,
if grown on U.S. corn lands, increase emissions by 50%. This result
raises concerns about large biofuel mandates
and highlights the value of using waste products.

Land Clearing and the Biofuel Carbon Debt
Joseph Fargione, Jason Hill, David Tilman, Stephen Polasky, Peter Hawthorne

Abstract
Increasing energy use, climate change, and carbon dioxide (CO2)
emissions from fossil fuels make switching to low-carbon fuels a high
priority. Biofuels are a potential low-carbon energy source, but
whether biofuels offer carbon savings depends on how they are
produced. Converting rainforests, peatlands, savannas, or grasslands
to produce food-based biofuels in Brazil, Southeast Asia, and the
United States creates a ‘biofuel carbon debt’ by releasing 17 to 420
times more CO2 than the annual greenhouse gas (GHG) reductions these
biofuels provide by displacing fossil fuels. In contrast, biofuels
made from waste biomass or from biomass grown on abandoned
agricultural lands planted with perennials incur little or no carbon
debt and offer immediate and sustained GHG advantages.

Uranium Exploration Near Grand Canyon

By FELICITY BARRINGER

Published: February 7, 2008

With minimal public notice and no formal environmental review, the Forest
Service has approved a permit allowing a British mining company to explore
for uranium just outside Grand Canyon National Park, less than three miles
from a popular lookout over the canyon’s southern rim.

If the exploration finds rich uranium deposits, it could lead to the first
mines near the canyon since the price of uranium ore plummeted nearly two
decades ago. A sharp increase in uranium prices over the past three years
has led individuals to stake thousands of mining claims in the Southwest,
including more than 1,000 in the Kaibab National Forest, near the Grand
Canyon.
