Atmospheric CO2 has just reached a peak not seen on Earth in 4 million years.
There is even little hope that the โปรโมชั่น slotxo global shutdown during the pandemic could bring relief from the climate crisis. But further evidence confirms that there is no such silver lining.New measurements of atmospheric carbon dioxide (CO2) levels show that concentrations of heat-trapping chemicals have risen to an unprecedented level that scientists cannot see in the modern reading age.
May had the highest CO2 levels through 2021, with average concentrations of 419.13 parts per million (ppm), researchers from the National Oceanic and Atmospheric Administration (NOAA) announced Monday.We are adding about 40 billion metric tons of CO2 pollution to the atmosphere per year," said Pieter Tans, senior climate scientist at NOAA's Global Monitoring Laboratory.
If we want to avoid extreme climate change The highest priority must be to reduce CO2 pollution to zero as soon as possible.Scientists say the new peak of 419.13 ppm is the highest monthly average since accurate atmospheric measurements began 60 years ago.But the true magnitude of this result has not been measured in the past decade. Because you have to go back in time a lot. To find the Earth's atmosphere with too much CO2 as it is now.
How far back? It is estimated around the time of the Pliocene, particularly around 4.1 to 4.5 million years ago, NOAA said, the last time the atmospheric load of carbon dioxide was comparable to today's polluted skies.We know this because researchers reconstructed atmospheric CO2 concentrations using sophisticated proxy methods, such as the composition of carbon isotopes found in marine sediments from various sites. in oceans around the world
