Hot Topic Solar System Earth Climate
The Oldest Ice Cores
Topic: Climate
A new study claims that ice cores from certain regions of Antarctica could provide a record of Earth's climate from 1.5 million years ago.

Small Increase in Hydrogen Sulfide Made Ancient Ocean Toxic for Life
Topic: Climate
A new study has provided insight into ocean chemistry during a dramatic climate event that occurred on Earth 93.9 million years ago. The results also hold clues about how future changes in ocean chemistry could affect life on Earth.

Reading Ancient Climate from Plankton Shells
Topic: Climate
A new study has shown that a daily record of climate change on Earth is recorded in ancient sea shells.

Without Plants, Earth Would Cook Under Billions of Tons of Additional Carbon
Topic: Climate
A new report is shedding light on how plants have prevented climate change on Earth since pre-industrial times. By absorbing billions of tons of carbon, ecosystems on land have been helping to cool down the planet.

Littlest Continent's Big Role in Sea Level
Topic: Climate
New research shows that the convergence of three atmospheric patterns in 2010 and 2011 cause so much precipitation over Australia that the world's ocean levels dropped.

'Runaway Greenhouse' Easily Triggered
Topic: Climate
A new study indicates that it might be easier than previously thought to initiate a 'runaway greenhouse' on planets. The research could change our understanding of the habitable zone around stars, and provide clues about how Earth's climate will change in the future as the Sun's brightness increases.

Rising Temperatures Boost Carbon Dioxide in the Tropics
Topic: Climate
A new study shows that generation of carbon dioxide in tropical ecosystems increases when temperatures rise, unlike ecosystems in other parts of the world.

Improving Climate Models with Permafrost
Topic: Climate
New data from permafrost studies are helping scientists understand the rate at which carbon dioxide is released during thawing. A crucial factor is water content in the soil, and its effect on the activity of microorganisms.

A Cor do Oceano: A Missão SABIA-Mar
Topic: Climate
Ao monitorar as mudanças na cor do oceano, tais como aquelas causadas pelos pigmentos fotossintéticos do fitoplâncton, os cientistas aprendem mais sobre a saúde e funcionamento geral do nosso planeta. Estes estudos poderiam também ajudar futuras missões a melhor observar e entender oceanos alienígenas.

The Color of the Ocean: the SABIA-Mar Mission
Topic: Climate
By monitoring the color changes in the ocean, such as those caused by photosynthetic pigments in phytoplankton, scientists learn more about the overall health and functioning of our planet. Such studies also could help future missions better observe and understand alien oceans.
