Nitrogen from rock could fuel more plant growth around the world – but not enough to prevent climate change

Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.

Melting Arctic sends a message: Climate change is here in a big way

Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.

Climate scientists and policymakers need to trust each other (but not too much)

Politicians are always being told to trust what climate scientists are telling them. But can you have too much of a good thing? What happens when the exchange of ideas becomes too cosy?
The Day After Tomorrow’s apocalyptic depiction of climate change is a little embellished. But such storylines can ignite conversations with people that mainstream science fails to reach. 20th Century Fox

Can ‘cli-fi’ actually make a difference? A climate scientist’s perspective

Climate scientists often bombard their audiences with facts and figures - a method of communication that often doesn't work. Perhaps this is where cli-fi can step in, with its compelling characters and just slightly embellished science.
Nobody can observe events in the future so to study climate change, scientists build detailed models and use powerful supercomputers to simulate conditions, such as the global water vapor levels seen here, and to understand how rising greenhouse gas levels will change Earth’s systems. NCAR/UCAR

Yes, we can do ‘sound’ climate science even though it’s projecting the future

People worry Washington is losing respect for science and even the centuries-old scientific method. Two climate scientists explain how science can be done when talking about the future.
