WAIMEA, Hawaii – The Mauna Loa Observatory in Hawaii measured carbon dioxide levels in the atmosphere and found the highest concentrations recorded on 3 April.
Researchers measured average atmospheric carbon dioxide Being 421.21 parts per million, which means that human CO2 has reached the halfway point of doubling pre-industrial levels.
“This work suggests that CO2 continues to build in the atmosphere. The COVID situation has not led to any notable change in buildup, nor would we expect a major impact,” Ralph Keeling, a professor Scripps Institution of Oceanography, UC San Diego told Fox television stations.

Emissions dropped by about 7% in 2020 compared to 2019 due to changes made by the COVID-19 epidemic, but Keeling said the drop is too small to show as a significant deviation for CO2 uptake And there was very little. .
“Even with the 7% drop, we were still adding CO2 levels to our atmosphere at a much higher rate. Atmospheric CO2 behaves like garbage in a landfill. As we continue to emit Yes, the stack of CO2 continues. ” Keeling said. “In recent years, the buildup has been sufficiently stable that each year’s level has surpassed previous year’s levels. It has continued for decades now, pushing into uncharted territory. CO2 levels at least Haven’t been high for 2.5 million years and maybe. Even longer. “
President Joe Biden signed an executive order on 20 January – just hours after he was sworn in – to restart the Paris Agreement, by trying to limit warming to 2 ° C (3.6 ° F) globally. A climate initiative to help reduce carbon emissions. Pre-industrial level.
This is a threshold that scientists call, if reached, the consequences of climate change will be revealed by the end of the century.
“There’s no time to start like today,” Biden said in January as he signed into action at the Oval Office.
“I think they are recognizing that it is actually better to be part of a group of 195 countries and try to deal with climate change. Climate change is the one thing that is killing all of us,” Helen Mountford , Vice President. For climate and economics at the World Resources Institute, Fox told television stations.
Carbon dioxide data on Mauna Loa in the 1950s c. Of the Scripps Institution of Oceanography. Was recorded by David Keeling. This makes the longest record of direct measurement of CO2 in the atmosphere.
NOAA introduced its own CO2 measurements in 1974, and they have since moved in parallel to those made by Scripps.
NOAA wrote that it appears that CO2 is continuing to increase as in previous years, which suggests that we need to make aggressive investments in renewable energy sources to deal with our global heating emergency.
Based on this data, scientists are expecting an average annual concentration to exceed 416 ppm.
“This year, CO2 levels were ~ 50% larger than the natural revolution, which prevailed ten thousand years before the Industrial Revolution. We are rapidly moving into a range that is considered dangerous from the point of view of climate impacts Is. Any solution. The climate problem will require major reductions in fossil-fuel emissions globally in the future.
It is important to note that Mauna Loa data are obtained at an altitude of 3,400 m (about 2.11 mi) in the northern subropics, so the readings may not be the same as the surface has a globally average CO2 concentration.
