Extreme Earth: Waves of Water, Wind and Heat
Topic: Climate
05/09/11
Research shows that increasing wind speeds and wave heights could be linked to climate change. However, not all recent and extreme weather events are due to changing climate. A separate study indicates that the record heat in Russia recorded in 2010 was a fluke, and unrelated to climate trends.

Turning Up the Gas
Topic: Climate
04/25/11
Greenhouse gases have increased more frequently in Earth's history than previously believed. Fluxes involved a significant exchange of carbon between surface reservoirs and the atmosphere. Higher levels of CO2 affect nutrient uptake by planets, which could cause problems as the modern climate continues to heat up.

Extraterrestrial DJs: spinning tunes for the stars
Topic: Alien Life
04/21/11

Pulling Back the Sheets
Topic: Climate
04/11/11
A new study shows that melting ice sheets in Greenland and Antarctica are contributing more to rising sea levels than other sources, such as mountain glaciers and ice caps. Studying these sheets is important, because if they collapse they could dramatically change the level of the oceans globally.

Wet and Dry
Topic: Climate
03/28/11

Zombie Invaders
Topic: Climate
03/14/11
The ability of organisms to adapt to our changing climate could cause profound changes to the biosphere. Some microbes might remain dormant in environments until conditions improve. Invasive species could move into new environments, potentially triggering a mass extinction.

Spotlight on Local Change
Topic: Climate
02/28/11
Astrobiology Magazine's climate blog, The Hot Zone, is focusing on the local effects of climate change in different places in the world. Changing climate trends are resulting in less snow in California's Sierra Nevada mountains and more heavy rain for the state of Queensland in Australia.

The Culture of Climate Change
Topic: Climate
02/07/11
Scientists study the links between the Earth's climate and biosphere, but new studies show that climate could also be intimately linked to human culture. This relationship between climate and culture may be apparent throughout human history.

Studying Cycles: Chemistry and Climate
Topic: Climate
01/24/11
New studies have shown that scientists have underestimated the effect that two chemical compounds may have on Earth's climate. Carbon dioxide and nitrous oxide can contribute to global warming and climate change, and might bring about a climate on Earth that life has never experienced before.

Reverence for the Heavens
Topic: Cosmic Evolution
01/13/11
For some, the contemplation of the cosmos is a religious experience. Vatican astronomers say this can lead to profound insights about ourselves and the nature of the universe.

Time for Climate Change
Topic: Climate
01/10/11
Earth's climate could take 100,000 years or longer to recover from rising CO2 if we don't mitigate our carbon emissions. Scientists studying one ancient bout of global warming 56 million years ago found that CO2 took about 30,000 to 40,000 years to settle out of the atmosphere.

Should We Stay or Should We Go?

Climate Change before it Goes Global
Topic: Climate
09/27/10
Whiffs of oxygen may have been present on Earth before the Great Oxidation Event. This may have allowed for niche environments for oxygen-dependent organisms before the global atmosphere became oxygen rich. This isn't the only example of how climate change can first occur regionally rather than globally.

Plants and the Carbon Capture Question
Topic: Climate
09/13/10
We have a long way to go in understanding climate change, but we do know that complex interactions between plants and the climate of Earth go well beyond the Carbon Cycle. Studying the links between life and climate will aid in understanding life's future on Earth.

The Atlantic and Pacific Climate Connection
Topic: Climate
08/30/10
Researchers are discovering new ways in which the Earth's oceans have influenced global climate. At the end of the last ice age, north Atlantic ice sheets melted, added fresh water and caused the collapse of the Atlantic Ocean conveyor belt. That should have plunged the northern Hemisphere into a deep freeze... but it didn't.

Engineering the Skies
Topic: Climate
08/23/10
If we could make one change to stave off climate change, what would it be? One scientist believes that getting rid of black soot is the answer. Other research shows that fighting climate change with geo-engineering tricks, such as pumping out aerosols to reflect sunlight, may not be a solution.

Climate Change by Degrees
Topic: Climate

Topic: Climate
06/21/10
How did the Earth stay warm 3.8 billion years ago when the young sun was 30% weaker? It's a mystery scientists have long been trying to solve, and it may come down to global warming. Ancient warming on Earth can also provide important clues concerning modern climate change.

Earth Blows Hot and Cold
Topic: Climate
06/14/10
