NASA study finds rising Arctic storm activity sways sea ice, climate
A new NASA study shows that the rising frequency and intensity of arctic storms over the last half century, attributed to progressively warmer waters, directly provoked acceleration of the rate of arctic sea ice drift, long considered by scientists as a bellwether of climate change.   view more (2008-10-07)

Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

Next-generation adaptive optics produces sharper Jupiter images
A two-hour observation of Jupiter using an improved technique to remove atmospheric blur has produced the sharpest whole-planet picture ever taken from the ground, according to astronomers from the University of California, Berkeley, and the European Southern Observatory (ESO).   view more (2008-10-03)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

Cranking up the volume-- Sounds travel farther underwater as world's oceans become more acidic
It is common knowledge that the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's atmosphere. However, fewer people realize that the chemistry of the oceans is also changing--seawater is becoming more acidic as carbon dioxide from the... view more (2008-09-30)

Metal-organic frameworks feel the pressure of Argonne scientists
Scientists at U.S. Department of Energy's Argonne National laboratory are putting the pressure on metal-organic frameworks (MOF).   view more (2008-09-26)

CO2 emissions booming, shifting east, researchers report
Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007.   view more (2008-09-25)

Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have... view more (2008-09-23)

How corals adapt to day and night
Researchers have uncovered a gene in corals that responds to day/night cycles, which provides some tantalizing clues into how symbiotic corals work together with their plankton partners.   view more (2008-09-15)

Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers.   view more (2008-09-15)

Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate.   view more (2008-09-12)

Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.   view more (2008-09-11)

NASA study illustrates how global peak oil could impact climate
The burning of fossil fuels -- notably coal, oil and gas -- has accounted for about 80 percent of the rise of atmospheric carbon dioxide since the pre-industrial era. Now, NASA researchers have identified feasible emission scenarios that could keep carbon dioxide below levels that some scientists... view more (2008-09-11)

Fuel Emissions From Marine Vessels Remain a Global Concern
Marine vessels are no longer resting in a safe harbor. The forecast for clear skies and smooth sailing for oceanic vessels has been impeded by worldwide concerns of their significant contributions to air pollution and greenhouse gas emissions that impact the Earth's climate.   view more (2008-09-10)

Bad sign for global warming: Thawing permafrost holds vast carbon pool
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.   view more (2008-09-04)

Thawing permafrost likely to boost global warming
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new... view more (2008-09-02)

No more big stink: Scent lures mosquitoes, but humans can't smell it
Mosquito traps that reek like latrines may be no more. A University of California, Davis research team led by chemical ecologist Walter Leal has discovered a low-cost, easy-to-prepare attractant that lures blood-fed mosquitoes without making humans hold their noses.   view more (2008-08-29)

Why is Greenland covered in ice?
There have been many reports in the media about the effects of global warming on the Greenland ice-sheet, but there is still great uncertainty as to why there is an ice-sheet there at all.   view more (2008-08-28)

Future for clean energy lies in 'big bang' of evolution
Amid mounting agreement that future clean, "carbon-neutral", energy will rely on efficient conversion of the sun's light energy into fuels and electric power, attention is focusing on one of the most ancient groups of organism, the cyanobacteria.   view more (2008-08-25)

Up, Up and Away: Studying Volcanoes With Balloon
People do all kinds of crazy things in Hawaii, but flying balloons over a volcano usually isn't one of them. Unless you're Adam Durant, that is.    view more (2008-08-15)

A bug's life... in a bubble
Hundreds of insect species live mainly underwater, but how do they breathe? University of Alberta researcher Morris Flynn did a study to find out how these species are able to remain underwater without drowning.   view more (2008-08-11)

Snapshot of past climate reveals no ice in Antarctica millions of years ago
A snapshot of New Zealand's climate 40 million years ago reveals a greenhouse Earth, with warmer seas and little or no ice in Antarctica, according to research published this week in the journal Geology.    view more (2008-07-29)

Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts.   view more (2008-07-24)

Amazon outflow is found to power ocean capture of carbon dioxide
Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study.   view more (2008-07-24)

NIST membrane model may unlock secrets of early-stage Alzheimer's
Researchers at the National Institute of Standards and Technology (NIST) and three collaborating institutions are using a new laboratory model of the membrane surrounding neurons in the brain to study how a protein long suspected of a role in early-stage Alzheimer's disease actually impairs a... view more (2008-07-24)
