A well-defined ocean warming trend originating off the United States East Coast is likely from super-heated and methane-enriched fluids emitted from numerous seafloor hydrothermal vents/hot springs (see figure 1 after the jump).
Supporting evidence: This trend has shown up on shallow Sea Surface (SST) maps since their advent in 1997 and has likely been present for thousands of years.
Study Excerpt: "Ilyinskaya et al. recorded the first atmospheric gas emission rate measurements from Katla, one of Iceland’s largest active volcanoes. This massive ice-covered caldera, which last erupted a century ago, was previously assumed to be a relatively minor emitter of CO2, but the new results suggest otherwise...The results indicate that Katla emits 12–24 kilotons of CO2 per day, which is more than double previous estimates of the emission rate of CO2 from all volcanic and geothermal sources in Iceland combined (2.7–5.8 kilotons per day)"
"These findings suggest that subglacial volcanoes—the emissions of which have not been considered in much detail, historically—may be major emitters of carbon dioxide. Because of this, their contributions to the global volcanic CO2 budget may have been underestimated."
“The politics of this were impossible a few years ago. But not so much now,” said Rafe Pomerance, chairman of the environmental alliance Arctic 21 and a four-decade advocate of increased action on global warming. “If we think the problem of climate change is catastrophic, how can we say that we can’t at least consider this as an option?” ...
Researchers have envisioned duplicating the phenomenon by launching jets equipped to fly to 70,000 feet, the lower reaches of the stratosphere, where they would release a sulfur compound. The effort would bleach blue skies a lighter color and make sunsets more vivid, while shielding Earth from some of the sun's rays. The flights would have to be numerous and long-running to create anything like the reflective power of the volcanic eruptions.
In the journal, the team wrote: “Through high-precision airborne measurements and atmospheric dispersion modelling, we show that Katla, a highly hazardous subglacial volcano which last erupted 100 years ago, is one of the largest volcanic sources of CO2 on Earth, releasing up to five percent of total global volcanic emissions.”
Boris Johnson, Angela Merkel, Emmanuel Macron, and Narendra Modi will apparently gather in the Netherlands. There, along with Bill Gates, UN head Antonio Guterres, and personnel associated with the European Union, the World Bank, and the International Monetary Fund, they’ll attend a climate summit hosted by the Global Center on Adaptation. ...
We’re told this summit "will launch a comprehensive Adaptation Action Agenda to kick start a transformational decade."
Donna Laframboise: "The chutzpah is astonishing. The global economy is in tatters. Billions face an uncertain future. Health care workers are exhausted. Yet this Clique of Self-Important People™ is full speed ahead, determined to impose its climate vision on the rest of us."
In the last 500 years only some 80 mammals are recorded as having gone extinct. In his book, More From Less, Andrew McAfee, a board member of HumanProgress.org, discusses how relatively rare recorded extinctions are – with some 530 across all species in the last five centuries. More importantly, he notes, the rate of extinction “appear[s] to have slowed down in recent decades; for example, no marine creatures have been recorded as extinct in the last fifty years.”
Matt Ridley, another board member and frequent contributor to this site, argues that despite the human population doubling in the last half-century, “the extinction rate of wild species, especially in the most industrialized countries,” seems to have fallen rather than increased. While absence of evidence isn’t the same as evidence of absence, and there might be millions of unrecorded species in the world’s oceans and tropical forests, the most aggressive claims rest on shaky foundations.
CNN: Jon Aars, a senior researcher at the Norwegian Polar Institute: "Polar bears are optimistic animals," Aars says. "It seems that they are quite resistant, and they are doing quite well despite the fact that they've lost a lot of their habitat." Despite the odds, Svalbard's polar bear numbers do not appear to have decreased in the last 20 years, he says.
Hulme: "January 12021, a new World Meteorological Organisation (WMO) climatological standard normal came into effect. The ‘present-day’ climate will now formally be represented by the meteorological statistics of the period 1991-2020, replacing those from 1961-1990. National Meteorological Agencies in member states are instructed to issue new standard normals for observing stations and for associated climatological products. Climate will ‘change’, one might say, in an instant; today, the world’s climate has ‘suddenly’ become nearly 0.5°C warmer. It is somewhat equivalent to re-setting Universal Time or adjusting the exact definition of a metre." ...
"So, what is the significance of the move to a new 1991-2020 WMO normal in January 2021? On the one hand, it is a pragmatic move to redefine ‘present-day’ climate for operational applications to that of the most recent 30-year period. On the other hand, it puts into play a third climatic baseline. Already existing is the ‘pre-industrial’ climate of the late nineteenth century and the ‘historic’ climate’ of 1961-1990, the latter about 0.3°C warmer than the former. And now there is the new ‘present-day’ climate of 1991-2020, in turn about 0.5°C warmer than the ‘historic climate’ of 1961-1990." ...
"Combining a climatic tolerance of 2°C—or indeed 1.5°C—with a pre-industrial baseline yields a very different climate target than, say, using a 1986-2005 baseline, the period widely adopted by IPCC AR5 Working Group I as their analytical baseline. The choices of both baseline and tolerance are politically charged. They carry significant implications for historic liability for emissions (La Rovere et al., 2002), for policy design (Millar et al., 2017) and for possible reparations (Roberts & Huq, 2015)."
