Time: 09.30-11.30 (GMT + 02:00)
Since the beginning of the industrial revolution, the oceans have taken up 30 to 40% of the total carbon dioxide (CO2) and 93 % of the heat added to the atmosphere through human activities.
For ecosystems, such changes may lead to sudden regime shifts when certain thresholds in warming, oxygen availability, and acidification are reached.
As an example, marine heatwaves have a high peak temperature and can push ecosystem from one stable state to another.
In this workshop, we will cover the definition itself in more detail along with recent findings on marine tipping points and regime shifts from the two EU Horizon 2020 projects COMFORT and TiPACCs and the Arctic Monitoring and Assessment Programme.
