Hot Topic Solar System Earth Climate
 
Without Plants, Earth Would Cook Under Billions of Tons of Additional Carbon
Topic: Climate
10/19/13
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
08/23/13
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
08/01/13
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
07/30/13
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
07/29/13
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
07/15/13
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
07/15/13
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.

The Anthropocene: Humankind as a Turning Point for Earth
Topic: Climate
06/24/13
In this interview, Dr. David Grinspoon discusses the implications of the Anthropocene -- a timescale defined by humanity as a geological force shaping the global landscape and evolution of our planet.

O Antropoceno: A Humanidade Como Um Ponto de Mutação Para a Terra
Topic: Climate
06/24/13
Nesta entrevista o Dr. David Grinspoon discute as implicações do Antropoceno – uma escala de tempo definida como a humanidade sendo uma força geológica a modificar a paisagem global e a evolução do nosso planeta.

Comparing Climates: From Earth to Exoplanets
Topic: Climate
05/09/13
Scientists gathered at NASA Headquarters this week to discuss how Earth’s climate compares to other locations in our solar system and beyond. By highlighting the similarities and contrasts between alien environments, we may gain a better understanding about changes in our home planet’s climate.
