The updated methods are providing a clearer picture of how Earth and its inhabitants evolved over the past 60,000 years - and thus, providing new insight into its future.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.

Earth's has gone through major climate changes in the past. They happened on time scales of millions of years and triggered mass extinctions. Our emissions are changing the climate much faster.
Discussions about climate change often skirt around the issue of population growth, but it is the main driver of rising carbon dioxide levels and many other environmental changes on a planetary scale.
Droplets rising from the Champagne vent on the ocean floor in the Mariana Islands. Fluids venting from the site contain dissolved carbon dioxide.

Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
New data from a NASA satellite show in unprecedented detail the flow of carbon dioxide into the atmosphere. Future satellites should even be able to detect the signatures of individual power stations.

Why is it so hard to reach consensus about how to slow climate change? Multiple time lags get in the way: some make it hard to convey the risk, while others prolong the search for solutions.
Extreme wet years are getting wetter and more common. This means Australia's terrestrial ecosystems will play a larger role in the global carbon cycle.
Forests and other land-based carbon stores held onto more carbon during colder historical climates.

When temperatures dipped between 1500 and 1750, the world's landscapes responded by storing more carbon. Now, with temperatures climbing, it's possible they will do the opposite and release even more.
Things got very wet, very quickly, in Brisbane in 2011.

Since 1999, Australia has swung between drought and deluge with surprising speed, because El Niño has fallen into sync with similar patterns in the Indian and Southern Oceans.
