According to a report from National Oceanic and Atmospheric Administration (NOAA) issued Monday, June 5, atmospheric carbon dioxide levels reached an all-time high last month, after rising rapidly.
Carbon dioxide levels recorded at NOAA’s Mauna Loa Atmospheric Reference Observatory in Hawaii reached nearly 424 parts per million (ppm) in May 2023, down from 421 ppm in May 2022 (annual levels of carbon dioxide)2 in the Northern Hemisphere at its peak in May).
According to scientists from NOAA and Scripps Institution of Oceanography affiliate University of California San DiegoThis rise in atmospheric carbon dioxide is the fourth largest annual increase on record, as scientists seek to stabilize carbon dioxide levels.2.
The current levels of carbon dioxide are More than 50% higher The pre-industrial era continues to rise even as countries strive to reduce fossil fuel emissions in hopes of meeting the target set by the 2015 Paris climate agreement, namely, limiting global warming to 1.5°C above pre-industrial levels by the end of the century.
“Every year we find that carbon dioxide levels in our atmosphere are increasing due to human activity,” he said Rick SpinradNOAA official in a statement. “Every year we see the effects of climate change in the heat waves, droughts, floods, wildfires and storms that occur all around us. […] We must do everything we can to reduce carbon pollution and save this planet and the life that inhabits it. »
For decades, scientists have warned that fossil fuel emissions must be reduced to avoid the devastating effects of climate change. This is because rising levels of carbon dioxide, which comes from burning fossil fuels primarily for transportation and electricity, traps heat in the atmosphere. This global warming effect prolongs droughts and heat waves and causes wildfires and more intense storms. UN scientists warned in March that the world was ‘on a tightrope’ as global temperature approaches the critical threshold of 1.5°C, estimated to be the extreme temperature increase to avoid drought, more deadly and catastrophic heat waves, storms and seas . high level. UN scientists also warned in October that greenhouse gas emissions will increase by 10% over 2010 levels by 2030, when they should certainly decline.
