What is happening in the Atlantic Ocean to the AMOC?

Real Climate

The Atlantic meridional overturning circulation (AMOC) is a large-scale overturning motion of the entire Atlantic, from the Southern Ocean to the high north. Graph by Ruijian Gou. The AMOC is a big deal for climate. It moves around 15 million cubic meters of water per second (i.e. 15 Sverdrup). For more on this see my Review Paper in Nature.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). Furthermore, the volume of the oceans increases from the melting of land ice. See for instance Benestad (2016).

Sea level in the IPCC 6th assessment report (AR6)

Real Climate

The IPCC has introduced a new high-end risk scenario, stating that a global rise “approaching 2 m by 2100 and 5 m by 2150 under a very high greenhouse gas emissions scenario cannot be ruled out due to deep uncertainty in ice sheet processes.”. The IPCC gives more consideration to the large long-term sea-level rise beyond the year 2100.

Climate change has already aggravated 58% of infectious diseases

A Greener Life

The consequences of climate change aren’t reserved for the oceans and atmosphere: Diseases have secured a larger presence in recent years thanks to global warming. In Scandinavia in 2014, an outbreak of cholera, a warm-water disease, shocked observers. We need to aggressively reduce greenhouse gas emissions.”.

Arctic Sea Ice Reaches its 2021 Minimum

Ocean Conservancy

In the Arctic Ocean, the summer sea ice minimum is an important milestone during this seasonal transition. The sea ice minimum occurs when the extent of sea ice covering the Arctic Ocean reaches its lowest point for the year. Thanks for signing up for Ocean Conservancy emails. Why do we care about Arctic sea ice, anyway?
