☆ Atmospheric CO2 now 50% higher than pre-industrial level -NOAA
  + stars: | 2023-06-05 | by ( ) www.reuters.com   time to read: +2 min
Measurements are taken in May because it is the month when CO2 peaks in the Northern Hemisphere. The outpost on Mauna Loa has measured atmospheric CO2 since 1958, when the level was less than 320 ppm, and shown a steady increase since then in what NOAA Administrator Rick Spinrad called "a direct result of human activity." NOAA began collaborating with Scripps on the measurements in 1974. This year's measurements were taken from a temporary site because lava flows cut off access to the Mauna Loa observatory in November 2022, NOAA said. (This story has been corrected to change NOAA's previously reported figure as 424 ppm and not 423 ppm, in paragraph 2.

Even now, when scientists want to test new carbon dioxide monitoring equipment, “they go to Mauna Loa,” Dr. Sweeney said.
☆ How U.N. climate conferences have tackled global warming

REUTERS/Russell Cheyne/File PhotoNov 2 (Reuters) - This year’s U.N. climate conference in Sharm el-Sheikh, Egypt, marks the 27th time since 1995 that world leaders have gathered to confront global warming. Here are some key moments in the global climate conversation:1800s - Throughout the 1800s, several European scientists study how different gases and vapours can trap heat in the Earth’s atmosphere. 1990 - At the U.N.’s so-called Second World Climate Conference, scientists highlight the risks of global warming to nature and society. 2015 - Global warming passes 1 degree Celsius. Signatories promise to try to keep global warming within 1.5 degrees C of the preindustrial average.
☆ Concentraţia de CO2 din atmosferă, la cel mai ridicat nivel de la debutul măsurătorilor

Anul trecut, în mai 2020, nivelul înregistrat a fost de 417 ppm. ''În fiecare an adăugăm în atmosferă aproximativ 40 de miliarde de tone de poluare prin CO2'', a declarat Pieter Tans, om de ştiinţă în cadrul NOAA. ''Adică un munte de carbon pe care îl dezgropăm din Pământ, îl ardem şi îl eliberăm în atmosferă sub formă de CO2... an după an'', a adăugat el. CO2 persistă în atmosferă şi oceane mii de ani, a subliniat NOAA. ''În pofida deceniilor de negocieri, comunitatea mondială a fost incapabilă să încetinească într-o manieră semnificativă, ca să nu mai vorbim de inversare, creşterile anuale ale nivelului de CO2 din atmosferă'', a notat NOAA.
