Global warming of more than 1.5 degrees Celsius will turn into disaster, UN Secretary General António Guterres said at a climate conference, TASS reports. The secretary general of the organization called on the G20 countries to reduce greenhouse gas emissions.
“The world is heading for a catastrophe – a warming of 2.7 degrees instead of 1.5 degrees, as everyone previously agreed to limit, – said Guterres.
“Science says that any warming above 1.5 degrees will be a disaster. In order to limit the rise in temperature … we need to reduce emissions by 45% by 2030, then we can achieve carbon neutrality by the middle of the century, ”he added.
In August, the UN Intergovernmental Panel on Climate Change (IPCC) called the observed climate change unprecedented, some of which are irreversible in the long term. In particular, according to experts, climate change is increasing the water cycle, which causes more intense rainfall and, as a result, provokes floods and more severe drought in many regions. In addition, global warming will accelerate the melting of glaciers. This will negatively affect the ocean ecosystem and humanity, leading to a decrease in oxygen levels.
In turn, with an increase in the average temperature on the planet by 1.5 degrees, the heat periods will become longer, and the cold weather will become shorter. An increase in the indicator by 2 degrees will be critical for agriculture and health care.
