Climate research published on Nov. 12 in the journal Scientific Reports claims Earth "is already past a point-of-no-return for global warming," which provoked the ire of many climate scientists. The research has glaring flaws (detailed later), ultimately making the dubious case that the planet's frozen soil, or permafrost, will inevitably "melt" (soil actually thaws), leading to a cycle of more warming as heat-trapping greenhouse gases leach from the carbon-rich soil. Though the scientific world is filled with quality, carefully vetted climate research, from time to time a "point of no return" study makes its way into a mainstream research journal and, unfortunately, might get amplified or misinterpreted by some news outlets. When you see these doomist-type headlines, it's crucial to remember that humanity still has great sway over how much we disrupt the climate in the coming decades. We haven't tipped the global climate, in terms of warming, past a "point of no return," according to climate scientists.
Several times over the past decade, climate change deniers have pointed to a so-called "hiatus" in global warming between 1998 and 2014 and used it to argue that climate change is a hoax. After all, the existence of a hiatus -- or, more accurately, a slowdown in global mean surface temperature over the past 15 years -- was acknowledged even by the Intergovernmental Panel on Climate Change in a 2013 report. How, the denialists questioned, can scientists say human activities are causing the Earth to heat up when the data shows a clear slowdown? The answer, according to a new analysis published Wednesday in the journal Science Advances, is that the hiatus -- or even a slowdown in the rate of ocean temperature rise -- never happened. The study reveals that measurements that showed the existence of such a slowdown were, in fact, the result of a "cold bias" creeping into data gathered by ocean buoys.
Paris – 2020 has tied 2016 as the hottest year on record, the European Union's climate monitoring service said Friday, keeping Earth on a global warming fast track that could devastate large swathes of humanity. The six years since 2015 are the six warmest ever registered, as are 20 of the last 21 -- evidence of a persistent and deepening trend -- the Copernicus Climate Change Service (C3S) reported. Last year's record high -- a soaring 1.25 degrees Celsius above preindustrial levels -- was all the more alarming because it came without the help of a periodic natural weather event known as an El Nino, which added up to two-tenths of a degree to the 2016 average, according NASA and Britain's Met Office. "It is quite clear that in the absence of El Nino and La Nina impacts on year-to-year temperatures, 2020 would be the warmest year on record," Zeke Hausfather, director of climate and energy at the Breakthrough Institute in Oakland, California, said. During an El Nino, which occurs every two to seven years, warm surface water in the tropical Pacific Ocean can boost global temperatures.
Glaciers in the Antarctic are melting from below, according to a study published in the journal "Science Advances." The world's seas were the warmest on record in 2018, scientists announced Thursday. Also, ocean temperatures are rising faster than previously thought, a new paper said. "If you want to see where global warming is happening, look in our oceans," said paper co-author Zeke Hausfather, in a statement. "Ocean heating is a very important indicator of climate change, and we have robust evidence that it is warming more rapidly than we thought," said Hausfather, who is a climate scientist with Carbon Brief.
