The 27th edition of the United Nations Climate Change Conference of Parties (COP27) is held between 6 and 18 November 2022 in Sharm El Sheikh, Egypt.

The summit brings together politicians, scientists and civil society to discuss our changing climate and negotiate action for achieving the climate goals set by the Paris Agreement, aiming to limit global warming to well below 2°C.

Research on Southern Ocean carbon sink funded by 4C receives Prix de Quervain award

The Southern Ocean is the largest ocean sink of carbon dioxide released by human activities. The amount of this anthropogenic carbon dioxide that is absorbed by the Southern Ocean remains highly uncertain. Recent research funded by 4C has attempted to reduce this uncertainty.

The evolution of climate change depends on the development of our society, demographics and economics over the next decades. Limiting global warming to below 2°C compared to pre-industrial levels, or preferably to 1.5°C as it is established in the Paris Agreement, would only be possible if we stop emitting greenhouse gases as soon as possible. On the current trajectories, the world is set to warm by around 2.5°C by 2100, and continue upwards thereafter

Bringing policy relevant cutting edge climate research to EGU 2022

The European Geosciences Union (EGU) is hosting its yearly General Assembly on 23-27 May 2022. The conference brings together scientists from the Earth, planetary and space science fields to present and discuss the latest research in their fields, in particular targeting early-career scientists.

A number of 4C researchers are participating in the event, presenting their findings on carbon cycle research and climate predictions. Policy-relevant results that can help reduce uncertainties and move towards a net-zero world are also showcased. 

Extreme dry and hot events linked to climate change put European ecosystems at risk a 4C study found

In 2018 and 2019, exceptional dry and hot summers had strong negative impacts on ecosystems and vegetation in central Europe, causing widespread browning and tree mortality events. Extreme dry and hot events like these have become more frequent over the past decades in western and central Europe, a trend that is expected to continue as global mean temperatures rise, posing a major threat to the stability of European forests.

Nutrients from rivers and coastal erosion are of crucial importance for the Arctic Ocean ecosystem finds a 4C study

Marine primary production is the foundation of the marine food chain and ocean ecosystems. It primarily occurs via photosynthesis by phytoplankton, which use inorganic carbon and nutrients to produce organic matter. 

Supporting policymaking at COP26 4C brings policy relevant climate research to the summit

COP26
Body

The UN Climate Change Conference of the Parties (COP) is the yearly summit that brings together world leaders, scientists and civil society to discuss greenhouse gas emissions and the measures that have been taken or need to be taken to address climate change. 

The conference is crucial for negotiating action to limit global warming to well below 2 degrees and aiming at 1.5 degrees, in line with the Paris Agreement, which was first adopted during COP21 in 2015. 

COP26 is the 26th COP summit, taking place in Glasgow, UK between 31 October and 12 November 2021. 

Global average temperature projected to remain constant after reaching zero CO2 emissions according to 4C report

The carbon budget is a powerful concept developed in the last decade to assess how much additional carbon dioxide (CO2) humans can emit before a temperature target will be reached with a given probability. It provides critical knowledge to policymakers in order to prepare appropriate mitigation plans.

Better understanding the relationship between the temperature increase and cumulative CO2 emissions is crucial in determining how the global mean temperature will change after emissions reach zero.
