The idea of planting trees can easily be misinterpreted. There is a difference between afforestation, reforestation and forest restoration.

There’s something a lot of people don’t know about soil. 

Planting trees to mitigate climate change is useful in the tropics. At higher latitudes trees can have a warming effect.

Podcast: Uncontrolled logging is taking its toll on wildlife and climate. Does planting trees work the other way around?

Scientists have revealed how life populating the shadowy ocean below the surface evolved as Earth’s climate cooled over millions of years. 

In Hanna Lee's childhood South Korea, afforestation was a happy success story. As a climate researcher, she has realized that planting trees is not always good.

A new global ice sheet reconstruction for the past 80 000 years in Nature Communications.

Highly probable ocean tipping points need to be taken equally seriously as potential singular catastrophic climatic tipping points, write scientists and stakeholders in a new PNAS research perspective.

Addressing gender imbalance in science

Future climate scenarios are beyond comparison with recent times. When evaluating models, researcher Petra Langebroek goes 50 million years back.

Movement of Intertropical Convergence Zone limits climate predictions in the tropical Atlantic, says study in Nature Communications.

Afforestation in Norway can increase local temperatures in Spring by as much as 1°C. 

Nele Meckler looks for climate answers in tiny droplets hidden in dripstones in tropical caves. The European Research Council supports her with the prestigous ERC Consolidator Grant.

One video on the climate system, every day in December.

As the ice was retreating at the end of the ice age, the melting was suddenly interrupted. A cold period of more than a thousand years followed.

Twenty years ago, there was little talk about climate. Climate scientists barely existed. As the Bjerknes Centre celebrates its 20th anniversary this year, we have more than 200 scientists who all explore the Earth's climate.

A comparison of Greenland ice sheet models shows that while the surface mass balance is most realistic in the most complex models, simpler and faster models compare fairly well.

Ocean currents have brought more heat into the northern seas after 2001. The northern extension of the Gulf Stream has warmed and probably also strengthened.

Cyclones in the Atlantic and Pacific Oceans are affected by the Gulf Stream and the Kuroshio. The temperature of the water below is only one of the factors controlling their development.

In 10,000 years the Greeland ice sheet will be gone, but what about Antarctica? Heiko Goelzer presents research for the coming millennia.
