WMO: The Covid-19 pandemic has not been of much help in slowing climate change

When much of the world fell into a blockade caused by the Covid-19 pandemic, scientists observed a significant reduction in greenhouse gas emissions and air pollution. And now the World Meteorological Organization (WMO) has released a latest statistic that describes the overall picture of climate change.

Specifically, the concentration of CO2 in the atmosphere continues to rise and is at risk of hitting record levels. More sadly, the trend shows no signs of slowing down.

In May, scientists described the decline in CO2 emissions due to the effects of climate change as an extreme phenomenon. At that time global daily CO2 emissions were once reduced by 17% at their highest level when many people had to stay home for isolation.

However, the analysis published around the same time showed that the amount of CO2 in the atmosphere continued to hit record highs. As the world began to relax blockade measures, emissions began to rise again.

While this may sound a bit contradictory, the above analysis is an important indicator, urging us to make more short-term corrections to reverse the long-term trend of climate change.

The blockade like last time is not enough to cut CO2 emissions

Scientists measure CO2 concentrations in the atmosphere in parts per million (ppm) and levels below 350ppm are considered safe for the planet. But according to the latest statistics at monitoring stations around the world, this number is at a record level.

In particular, at Mauna Loa station in Hawai it recorded 414.38ppm in July, up from 411.74ppm last year. While at Cape Grim station in Australia, the figure was 410.04ppm, up from 307.83ppm last July.

Secretary-General of the United Nations António Guterres emphasized: “This is an unprecedented year for people and the planet. The COVID-19 pandemic has disrupted life around the world. At the same time planetary warming and climate disruption continue. out.

It has never been clear that humans need a cleaner, longer-lasting transition to tackle the climate crisis and achieve sustainable development. We must turn pandemic recovery a real opportunity to build a better future. We need science, solidarity and solutions.

Research shows that the period from 2016 to 2020 is likely to be the warmest five-year period ever recorded.

To keep the global average temperature from exceeding 1.5 degrees Celsius (since pre-industrial times) this century, the production of greenhouse gases needs to be cut urgently.

Specifically, by 2030, the world will need to cut the emissions of the top six emitting countries to have a chance to keep these temperatures below 1.5 degrees Celsius. To do this, obviously they We need to reduce CO2 emissions at a large scale like the last pandemic time from now to the end of the decade.

Global sea levels are rising much faster than previously recorded. From 2016 to 2020, the rate of increase is 4.8 mm per year, an increase of more than 4.1 mm recorded between 2011 and 2015. The level of sea ice in the Arctic continues to decline, at a rate of 13%. every decade.

Rising temperatures also cause droughts and heat waves and increase the risk of wildfires and many other natural disasters.
