UN: ‘world’s climate goals need drastic adjustment’
When the ambitions of the countries that signed the Paris climate agreement will be carried out, they will not be sufficient to limit global warming to 1,5 degrees. Not even when additional measures are taken after 2030. This is the conclusion of the Intergovernmental Panel on Climate Change (IPCC) of the United Nations, the most important report since the Paris climate agreement in 2015.
Zero emissions by 2050
The report describes the consequences of a global warming scenario of 1,5 degrees and one of 2 degrees. According to the report, CO2 emissions worldwide need to go down drastically before 2030, otherwise we will have to get CO2 out of the air. CO2 emissions have to decrease with 45% by 2030, compared to 2010, to reach the level of zero emissions by 2050.
When temperature on earth will continue to rise at the actual pace, we will probably achieve the 1,5-degree level of global warming between 2030 and 2052, with remaining consequences for the climate, like rising sea levels, warns the climate panel.
The panel concludes that the risks for climate, biodiversity and the environment will be far less radical with a 1,5-degree scenario than with a 2-degree scenario, making the sea level rise 26 to 77 cm by 2100 with a 1,5-degree scenario, and an extra 10 cm with a 2-degree scenario.
According to the IPCC, it is technically possible to bring down global warming significantly but we will need fast and radical changes from the energy industry, among others. “We will need serious emission reductions and numerous options to fight global warming.”
Hydrogen and bio fuels
Nuclear energy and the collection of CO2 will play an important role in the transition. Also gas will keep an 8% market share in the production of electricity. The use of coal, however, will be stopped almost completely by then. The industry can reduce its CO2 emissions drastically by collecting, stocking and re-using CO2, and by using hydrogen and bio fuels, writes the IPCC.
“Limiting global warming to 1,5 degrees is absolutely necessary”, concludes Joris Thijssen, Greenpeace director for the Netherlands. “The report is a last warning but also an opportunity to stop the disastrous consequences of global warming.” The environmental organization expects that the goal of the climate agreement of 49% CO2 emission reduction will be increased to 60% in 2030.
