Arctic warming is thawing the permafrost and releasing methane into the atmosphere. Scientists warn of similarities to the world's greatest extinction, the Permian extinction.
Heatwaves too hot to survive are forecast for later this century. Deadly mega-heatwaves lasting months are predicted every other year for regions around the world. Billions will be affected.
geology
The rock lockdown for CO2. Ground up basalt and olivine may absorb gigatonnes of CO2. Scientists are investigating on a beach in the Bahamas.
carbon economy
Dr Stuart Licht's new company C2CNT has found a way to convert CO2 in the air into highly priced graphene and carbon nanotubes. Nanotechnology is the next big thing, but will it be enough to use up all the excess CO2 in the atmosphere?
agriculture
Soil stores a massive amount of carbon, about 3000 gigatonnes worth, and there's room for even more.
urban planning
To prepare for higher temperatures, we need cool cities. Urban planning can bring down the temperature, even in the hottest parts of the planet.
construction
Heatwave-proof homes will soon become a necessity. Passive cooling is a way to cool your home down in a heatwave, and to stop the reliance on air-conditioners as the single solution to the heat.
