The world meteorological organization of the United Nations said that in the next five years will increase the likelihood that global temperatures will rise by more than 1.5 °C compared to preindustrial period.
Organization estimated a 20% probability that this threshold will be overcome by 2024.
It is reported that currently the average temperature on Earth by 1 °C above the pre-industrial period. The last five years have been the warmest in the entire history of observations.
“A new study shows a huge problem to be solved to achieve the goal of the Paris agreement on climate change. It is how to ensure that global temperature rise in this century is significantly lower than 2 °C compared to pre-industrial levels, and to undertake efforts to limit temperature increase to 1.5 °C,” said WMO Secretary-General petteri Taalas.
He noted that the slowdown of industrial production on the background of the pandemic coronavirus will not substitute for sustained and coordinated action in the field of climate. Because of the great longevity of CO2 in the atmosphere, reducing emissions this year will not lead to a decrease in the concentration of CO2 in the atmosphere, global temperatures will rise further.
Taalas said that the inability of people to cope with climate change could threaten the well-being of mankind, ecosystems and the economy for centuries.
Scientists say that this year in the Arctic is probably the average temperature will be two times higher than the world average, the smallest temperature change expected in the tropics and mid-latitudes of the southern hemisphere.
November 4, 2016 came into force in the Paris climate agreement, which requires measures to prevent climate change. The document already ratified by more than 180 countries, including India. In the list, which is published on the website of the United Nations, the United States, but in 2017 they officially informed about the withdrawal from the agreement.
The Paris agreement provides for the limitation of greenhouse gas emissions to a level where they will be completely absorbed by plants and oceans, to the end of this century; the slower growth of average annual temperature, so that it does not exceed more than two degrees average temperature of the planet to pre-industrial times; the establishment of a Fund, through which rich countries will help the poor to move to cleaner forms of energy.
