Greenhouse gas emissions are almost back to pre-corona crisis levels. Measured concentrations have reached record highs and the period 2016-2020 will be the warmest ever, international climate scientists say in a report presented today.
They have united in United in Science 2020. Scientists say that setting climate targets for global warming in this way is almost unrealistic. Only broad, international cooperation can ensure that the agreements made in the Paris Accord can be met.
During the first months of the corona crisis, CO2 emissions fell sharply, but throughout the world the economy is picking up again, causing more emissions from factories and cars. The good figures of a few months ago are cancelled out by the start-up of the industry.
More drought, melting ice caps
The good figures of a few months ago are cancelled out by the start-up of the industry. The consequences of climate change are becoming more and more clear, the scientists say. There are more heat waves, forest fires, it’s drier and ice caps are melting.
“This has been a tough year for man and the planet. The corona crisis has disrupted lives worldwide and at the same time global warming and climate change have continued unabated,” writes UN Secretary-General Guterres in the foreword to the report.
This is the second time that United’s scientists in Science 2020 have presented a report on climate change. The group is led by WMO, the World Meteorological Organization.
