'What is the reason for the lack of warming observed at the surface of the Earth since about 1997? Many causes have been proposed, and with increasing frequency, but most only represent partial explanations.' 'The ocean heat content is not behaving as some expected. (The past 10 years the oceans) shows no warming in upper most layers. If the heat is there, it must be deeper, far harder to detect. And possibly locked away for thousands of years.'
Easterbrook: 'It really isn’t a mystery at all, it was predicted in 1999 on the basis of consistent, recurring patterns of the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) and global climate.'
Study's conclusion: 'The decaying solar activity makes the recently recorded global temperatures flatten out and thus disguises the real climate development. With a steady level of cycle-average solar activity the global temperatures would have shown a steady rise from 1980 to present (2013) in agreement with the increasing atmospheric concentrations of green-house gasses, primarily carbon dioxide and methane , and not the levelling-off actually observed since 2001.'
Meteorologist Anthony Watts comment: Despite the fact that 'there are numerous claims that solar activity (and the slight increase in TSI seen in the last 30 years) can’t explain the global warming we’ve seen, but yet somehow the recent period of low solar activity can explain the pause'
'The heat is still coming in, but it appears to have gone into the deep ocean and, frustratingly, we do not have the instruments to measure there,' said Professor Ted Shepherd of Reading University. 'Global warming has certainly not gone away.'
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)."
Christopher Monckton: "At long last, following the warming effect of the El Niño of 2016, there are signs of a reasonably significant La Niña, which may well usher in another Pause in global temperature, which may even prove similar to the Great Pause that endured for 224 months from January 1997 to August 2015, during which a third of our entire industrial-era influence on global temperature drove a zero trend in global warming. ... As we come close to entering the la Niña, the trend in global mean surface temperature has already been zero for 5 years 4 months.
However, the new Pause is at a surface-temperature plateau 0.3 C° above the old Pause."
