The global temperature rise must be kept below +2°C by the end of the century to avoid catastrophic climate change.
A new 3D cartoon, Planet Blue, will help parents strike that balance by combining laughter and heart-pounding adventures with a positive attitude about our ability to save the planet.
A new study suggests that plate tectonics -- the dynamic processes that formed Earth's mountains, volcanoes and continents -- began about 3 billion years ago. By analyzing trace element ratios that correlate to magnesium content in ancient Earth's crust, the researchers provide first-order geochemical evidence for when plate tectonics first got underway.
A deal to attempt to limit the rise in global temperatures to less than 2C has been agreed at the climate change summit in Paris.
An international research team reports that the rapid increase in global carbon dioxide emissions from fossil fuels has slowed in the past two years, underlining the need for action to permanently lower emissions.
Some of the five mass extinctions Earth experienced in the past were driven by climate changes. Future Earth will be just fine.
Tech industry titans are banding together to try to ensure the world has enough energy, with less of the carbon emissions tied to global warming.
A man walks through hundreds of pairs of shoes displayed in Paris as part of a rally called "Paris sets off for climate" on Sunday, Nov. 29. More than 140 world leaders are gathering around Paris for high-stakes climate talks this week.
When biomass is combusted the carbon that once was bound in the growing tree is released into the atmosphere. For this reason, bioenergy is often considered carbon dioxide neutral. Research from Sweden, however, shows that this is a simplification. The use of bioenergy may affect ecosystem carbon stocks, and it can take anything from 2 to 100 years for different biofuels to achieve carbon dioxide neutrality.
Climate negotiations resume in South Africa today. In the United States, the hot air has yet to stop blowing.
