Report: There is no positive impact on climate during a pandemic

Global average temperature It was 1.2 degrees higher last year than it was during the pre-industrial period (1850-1900). 2020 was one of the three warmest years measured, and 2011-2020 was the warmest period in ten years on record.

Greenhouse gas concentration The increase in the atmosphere continued in 2019 and 2020. The average previously exceeded 410 parts per million, parts per million, and could reach 414 parts per million in 2021. Although the epidemic has led to a decrease in greenhouse gas emissions The new greenhouse effect by reducing economic activity worldwide, except that it had no appreciable effect on greenhouse gas concentrations in the atmosphere.

In 2019, it was the world’s oceans Warmer than ever, a development that will likely continue into 2020.

In Death Valley, USA, 54.4 ° C was measured in August 2020. It is the highest temperature ever measured since 1913, and possibly the highest temperature ever.

ExtremeVader: Africa and Asia were hit by torrential rains and floods, and in some areas “abnormal rains several times in 2020.” There were heat records in several places, with 54.4 in the first row in Death Valley, 39.7 in Cuba and 38 in Siberian Verkhoyansk. In Arctic Siberia, the average temperature was three degrees higher than normal, which, among other things, led to widespread ground fires.

This, among other things, explains the World Meteorological Organization (World Meteorological Organization) The latest climate report, published at 5:30 pm on Monday, according to a press release.

The report examines climate indicators such as the concentration of greenhouse gases, rising temperatures on land and in the water, rising sea levels, melting ice, how glaciers are shrinking and severe weather.

It also puts focus On socio-economic impacts such as migration, migration, food security, and impacts on land and water ecosystems.

“All key indicators, with the impact information presented in this report, confirm that climate change is occurring unabated, and indicate the increasing incidence of extreme weather, damage and losses affecting people, societies and economies. The negative climate trend will continue for decades, regardless of whether we have succeeded in mitigating Impacts. So it is important that we invest in adaptation. One of the most powerful ways to do this is to invest in early warning systems and networks for observing weather, “said Professor Petteri Taalas, Secretary-General of WMO in a written comment on the release of the report.

He said that many of the least developed countries have gaps in their monitoring systems and lack the latest technology to monitor weather, climate and water.

The COVID-19 pandemic worsens For those already affected by severe weather, among other things, transportation restrictions, for example, have delayed relief efforts – but have also made climate monitoring more difficult.

“This report shows that we have no time to waste. Climate change and the already expensive impacts on people and climate. This is the year of action. Countries must make a decision on zero emissions by 2050. They must put in place ambitious plans to reduce global emissions by 45%.” Percent compared to 2010 by 2030. We must act now to protect people from the catastrophic effects of climate change. ”United Nations Secretary-General António Guterres commented on the report.
