Peat fire emissions may shed light on climate change

Fri, 2015-01-16 13:45
Researchers are beginning a study of the climatic effects of peat fire emissions. "This project is going to provide the much-needed information on peat smoke aerosol properties for integration in satellite retrieval algorithms and climate models," the lead researcher says. "Based on my initial findings, I hypothesize the peat smoke is made up of brown carbon and not black carbon. Brown carbon is a class of organic carbon aerosol which, unlike black carbon, strongly absorbs incoming solar radiation in the shorter wavelengths, or near ultraviolet."

Oceans and climate science: Higher water mark

UK Only Article:  standard article Issue:  Seize the day Fly Title:  Oceans and climate science Rubric:  The rise in sea levels may be accelerating Main image:  20150117_STP002_0.jpg TIDES ebb and flow but mean sea levels are among the constants of climate science. Though things like the recent slowdown in the rise of average surface temperatures are puzzling, scientists can at least point to higher sea levels as clear evidence that climate change is real. The rise is caused by thermal expansion (hot water expands) and by melting ice sheets. And the facts are observable: thousands of gauges—such as that pictured above—measure tides around the world, with some records going back to the 18th century. But this evidence is not as irrefutable as it might seem. The coverage of tidal gauges is patchy. Most are in coastal waters, so the high seas are poorly measured. The majority are in the northern hemisphere. Few are near the poles. The records, says Carling Hay of Harvard University, are “very noisy ...

TIDES ebb and flow but mean sea levels are among the constants of climate science. Though things like the recent slowdown in the rise of average surface temperatures are puzzling, scientists can at least point to higher sea levels as clear evidence that climate change is real. The rise is caused by thermal expansion (hot water expands) and by melting ice sheets.

The coverage of tidal gauges is patchy. Most are in coastal waters, so the high seas are poorly measured. The majority are in the northern hemisphere. Few are near the poles. The records, says Carling Hay of Harvard University, are “very noisy [and] sparse”. It was not until the spread of satellite observations in the 1990s that measurement of sea levels became reliable and global. All sorts of adjustments are needed to make sense of earlier data and produce a complete record.Dr Hay and her colleagues have come up with a new way of doing this, reported in this week’s ...

Estimated social cost of climate change not accurate, scientists say

Emissions-free cars get closer

Thu, 2015-01-08 12:59
Hydrogen fuel cells -- possibly the best option for emission-free vehicles -- require costly platinum. Nickel and other metals work but aren't nearly as efficient. New findings help pin down the basic mechanisms of the fuel-cell reaction on platinum, which will help researchers create alternative electrocatalysts.

Not just rain: thunderstorms also pour down ozone

Thunderstorms and ozoneThe finding has implications for climate change and air qualityScientists find unequivocal evidence that thunderstorms move ozone from the stratosphere down toward Earth's surface, affecting air quality and climate.Yes

January 7, 2015 | A new study in Geophysical Research Letters offers for the first time unequivocal evidence that large storms move significant amounts of ozone from the stratosphere down to the troposphere, the lowest part of the atmosphere. The finding has implications for global climate because tropospheric ozone is a powerful greenhouse gas as well as a pollutant that affects human health and the environment.

NASA finds good news on forests and carbon dioxide

Fri, 2015-01-02 08:47
A new NASA-led study shows that tropical forests may be absorbing far more carbon dioxide than many scientists thought, in response to rising atmospheric levels of the greenhouse gas. The study estimates that tropical forests absorb 1.4 billion metric tons of carbon dioxide out of a total global absorption of 2.5 billion -- more than is absorbed by forests in Canada, Siberia and other northern regions, called boreal forests.
