In recent times, climate skeptics have been peddling a lot of nonsense about average temperatures actually cooling over the last decade.
We also hypothesize that shoaling of the thermocline over the EEIO, corresponding to a subsurface cooling trend (Alory et al. 2007), can make this region more susceptible to the wind — thermocline feedback and leads to frequent occurrences of positive events in recent decades.
The Kashmir conflict has been hot and violent over much of the last two decades, but it had cooled off in recent years and tourism picked up.
Some highlights: Over part of the past year, the Pacific was in its cyclical cool phase, called La Niña; the Arctic remained far warmer than usual for recent decades.
That flattening allows the small forcing due to the solar cycle minimum, a delayed bounceback effect from Pinatubo cooling, and recent small volcanoes to cause a decrease of the planetary energy imbalance over the past decade.
With the recent decline in solar flux and the shift to cool phases of ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.
I say «almost» because it gets the first decade after 1850 a bit too cool which might suggest recent warming is slightly more than is typical, but to amount to such a small error over 100 years shows it to be minuscule.
We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian) brown cloud — and that air quality measures over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».
Weather fluctuates, and as a consequence itâ $ ™ s easy enough to point to an unusually warm year in the recent past, note that itâ $ ™ s cooler now and claim, â $ œSee, the planet is getting cooler, not warmer!â $ But if you look at the evidence the right way Ââ $» taking averages over periods long enough to smooth out the fluctuations â $» the upward trend is unmistakable: each successive decade since the 1970s has been warmer than the one before.
They were poor in forecasting (or «projecting») decadal warming: 0.2 C per decade (AR4) or 0.15 to 0.3 C per decade (TAR), compared to an actually observed slight cooling over the most recent decade.
Regarding clouds, recent trends suggest a slight decline in total cloud cover over several decades, due to a reduction in low clouds, which exert a net cooling influence, while high cirrus clouds, which are net warmers, have remained relatively constant.
«Specifically, ClimateGate revealed that the historical temperature datasets have been manipulated over the years to make the 1930s appear cooler and recent decades appear warmer,» said Ebell.
For example, Mann and Emanuel (2006) hypothesize that a reduction in aerosol - induced cooling over the Atlantic in recent decades may have contributed to the enhanced warming of the tropical North Atlantic, relative to global mean temperature.
This means that if the GCR - warming hypothesis is correct, this increase in GCRs should actually be causing global cooling over the past five decades, and particularly cold temperatures in recent years.
The recent excitement surrounding the upcoming launch of the Apple Watch has made it easy to forget that GPS giant Garmin has been making some pretty cool «smart» watches for over a decade.
