Because the oil and fuel industries proceed to ramp up their plans to extract extra fossil fuels from beneath the floor of the Earth, the planet itself is sending warning indicators that issues are about to get quite a bit hotter. The loudest of these warnings pertains to floor temperature of the oceans that cowl greater than 70 p.c of the Earth.
In a letter revealed within the journal Advances in Atmospheric Science final month, a gaggle of scientists warned that sea floor temperatures final yr had been “off the chart”, with dire implications for atmospheric regulation and storm depth. “Heat oceans intensify atmospheric circulation and related excessive occasions,” Francisco Eliseu Aquino, the deputy director of Brazil’s Polar and Local weather Heart, instructed The Guardian. “The report temperature and excessive occasions noticed on the planet in 2023 haven’t handed. The planet has not cooled down.”
Francesca Guglielmo, a senior scientist on the EU’s Copernicus satellite tv for pc monitoring service, stated 2024 had began as 2023 ended, with “distinctive temperatures and lots of excessive occasions”. She pointed to a latest forecast by the Barcelona Supercomputing Heart that prompt there was a very good probability 2024 will set a brand new report with world temperatures passing 1.5C above pre-industrial ranges for the primary time. Some local weather scientists suppose we now have already handed that temperature stage. A report by Berkeley Earth final month stated,
2023 was the warmest yr on Earth since 1850, exceeding the earlier report set in 2016 by a transparent and definitive margin. The worldwide annual common for 2023 in our dataset was estimated as 1.54 ± 0.06 °C (2.77 ± 0.11 °F) above the common throughout the interval 1850 to 1900, which is historically used a reference for the pre-industrial interval. That is the primary time that any yr has exceeded the important thing 1.5 °C (2.7 °F) threshold. The final 9 years have included all 9 of the warmest years noticed within the instrumental report.
Guglielmo stated scientists had been now contemplating dangers that had been unthinkable till just lately. “2023 has damaged so many information that plenty of new hypotheses, together with the daybreak of a brand new part within the world warming fee, have been floated. These hypotheses weren’t almost as prevalent a yr in the past.”
Excessive Temperature, Excessive Danger
“Fueled by excessive climate and local weather extremes, the frequency of local weather associated disasters has dramatically risen in recent times,” stated Raul Cordero, a local weather professor on the College of Groningen and the College of Santiago. “In some areas of the world, we face climate-fueled disasters for which we aren’t ready, and it’s unlikely that we will absolutely adapt to them.”
Richard Betts, of the Met Workplace’s Hadley Heart within the UK, stated many extremes, together with longer heatwaves, heavier rainfall, elevated drought and extra hearth climate, had been changing into extra extreme resulting from human brought about local weather change that’s resulting in an surroundings that’s is at the next temperature than at any time in human civilization.
“We will nonetheless restrict the extent to which extremes worsen if we urgently scale back greenhouse fuel emissions to internet zero – however with world emissions nonetheless rising, it’s arduous to not be more and more involved about how we’ll take care of what’s coming,” Betts stated. “We already must adapt to the modifications that we’ve already brought about, and adaptation will turn into more and more tough the longer we depart it to cut back emissions.”
Temperature And Atmospheric Rivers
You don’t need to be a scientist to know that as air rises in temperature, it’s able to holding extra moisture. Extra moisture means heavier rain that last more than typical. Southern California is now struggling the results of two monster storms that dumped over 6 inches of rain on the realm up to now few days, resulting in large flooding and mudslides. Governor Gavin Newsom has declared a state of emergency in these areas.
These storms have been supercharged by hotter than regular temperature occasions over the Pacific Ocean throughout what’s termed an El Niño occasion. In line with Wikipedia, El Niño — Southern Oscillation (ENSO) is a local weather phenomenon that reveals irregular quasi-periodic variation in winds and sea floor temperatures over the tropical Pacific Ocean. It impacts the local weather of a lot of the tropics and subtropics, and has hyperlinks to larger latitude areas of the world. The warming part of the ocean floor temperature is named El Niño and the cooling part as La Niña. The Southern Oscillation is the accompanying atmospheric part, which is coupled with the ocean temperature change.
Gabriel Boric, the president of Chile, has declared two days of nationwide mourning after that nation’s lethal forest fires that claimed greater than 120 lives within the Valparaíso area. These fires comply with a decade-long drought within the space and a shift from various pure forests, that are extra resilient to fireside, to monoculture plantations, that are extra susceptible.
2023 was the most well liked yr in human historical past. Final month was the warmest ever January. Many areas within the northern hemisphere are sweltering in heatwaves that may be extra regular in June. Marine scientists are shocked by the extended and intense warmth on the floor of the oceans.
Scientists say the intense warmth is generally the results of human exercise, such because the burning of oil, fuel and coal and the reducing down of forests. This has been amplified by pure elements, significantly the El Niño occasion that began final yr and is predicted to proceed till spring on the earliest. This yr has a one in three probability of being even hotter than final yr’s report, in keeping with the US’s Nationwide Oceanic and Atmospheric Administration.
The Takeaway
Amidst all this excessive temperature insanity, the MAGA idiots are beating the drums for his or her messiah, a disgraced former president who suffers from a sophisticated case of megalomania. (Is there such a factor as MAGAlomania?) The sport plan, in keeping with The Guardian, is as soon as again in workplace, the whole dismantling of the Bipartisan Infrastructure Act and Inflation Discount Act, the cessation of all authorities help for renewable vitality, a large enhance in fossil gas extraction and exports, and changing your entire federal paperwork with partisan loyalists who will upend any try to cut back greenhouse fuel emissions in America.
Will people dwell of die? That’s the nub of the subsequent election. It’s not about immigration or support to Ukraine. It’s about whether or not the US might be a frontrunner within the battle to maintain the temperature of the Earth low sufficient to permit people to outlive or not. Please vote responsibly.

I do not like paywalls. You do not like paywalls. Who likes paywalls? Right here at CleanTechnica, we applied a restricted paywall for some time, but it surely at all times felt fallacious — and it was at all times powerful to resolve what we must always put behind there. In concept, your most unique and finest content material goes behind a paywall. However then fewer folks learn it!! So, we have determined to fully nix paywalls right here at CleanTechnica. However…
Thanks!
