Map of the Week – Global sea surface temperature regional trend
This week saw several events related to climate change. On 28 June, the Council of the European Union adopted the European Climate Law which sets out a binding objective of climate neutrality in the European Union by 2050.  On 29 June, the Climate Pact Day of Action took place. European Green Deal Climate Pact Day of Action aimed to show that, by taking action, we all have a part to play in building a greener tomorrow.
How is climate change affecting the ocean? The Copernicus Marine Service Ocean State Report published in 2020 provides a summary overview on the major impacts of increasing greenhouse gas emissions and resulting climate change on the ocean including ocean acidification, ocean warming, sea level rise and decreasing sea ice extent in the Arctic. It points out that Ocean Heat Content and Sea Surface Temperature are two important measures of ocean warming. Ocean Heat Content represents the heat energy stored in the ocean. Sea Surface Temperature is an Essential Climate Variable which provides insight into the flow of heat into and out of the ocean. The Copernicus Marine Service time series shows that the average global sea surface temperature has risen at a rate of 0.015 ± 0.001 °C per year between 1993 and 2019. Sea Surface Temperature does not rise homogeneously and thus some regions are more threatened than others. Ocean warming contributes to sea level rise and threatens marine ecosystems, putting people, economies and food security at risk.
In addition to climate change mitigation, climate change adaptation is therefore essential to face the impacts of climate change and build resilience. This was the subject of the 5th European Climate Change Adaptation Conference (ECCA 2021) which took place from 25 May to 22 June 2021.
