And that means we are likely headed toward a period of
rapid surface temperature warming.
Not exact matches
If this
rapid warming continues, it could mean the end of the so - called slowdown — the period over the past decade or so when global
surface temperatures increased less rapidly than before.
At that point in geological history, global
surface temperatures were rising naturally with spurts of
rapid regional
warming in areas like the North Atlantic Ocean.
The
rapid warming of the Arctic introduces an interesting dilemma: large regions of the Arctic are not covered by either
surface stations or satellites, so the
temperatures that increase the fastest are not being measured in most of the datasets.
In March 2009, Michaels, under the auspices of the Cato Institute, circulated a draft advertisement that stated: «
Surface temperature changes over the past century have been episodic and modest and there has been no net global
warming for over a decade now... The computer models forecasting
rapid temperature change abjectly fail to explain recent climate behavior.»
It looks likely that the
rapid warming of the Arctic has broken the thermometer
temperature record in two different ways - firstly by violating the assumption that unobserved regions of the planet
warm at a broadly similar rate to observed regions, and secondly by violating the assumption that neighbouring regions of the planet's
surface warm at a similar rate.
Since the very
warm surface temperatures of 1998 which followed the strong 1997 - 98 El NinÌ o, the increase in average
surface temperature has slowed relative to the previous decade of
rapid temperature increases, with more of the excess heat being stored in the oceans.
«claims that «Global
warming is the unusually
rapid increase in Earth's average
surface temperature over the past century» are erroneous and indicative of either ignorance or duplicity on the part of NASA's Earth Observatory, NASA's Climate Consensus page, The Daily Mail, the EPA and many others.»
Regardless, claims that «Global
warming is the unusually
rapid increase in Earth's average
surface temperature over the past century» are erroneous and indicative of either ignorance or duplicity on the part of NASA's Earth Observatory, NASA's Climate Consensus page, The Daily Mail, the EPA and many others.
Harvey's
rapid intensification from a tropical depression to an 85 - mile - per - hour hurricane in less than 24 hours was due to favorable conditions —
warm water and low wind shear [29]-- in the Gulf of Mexico, where sea
surface temperatures were up to 2.7 - 7.2 °F (1.5 - 4 °C) above the 1961 - 1990 average.
Global
warming is the unusually
rapid increase in Earth's average
surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels.
And yet over the entire period question containing these six cooling trends, the underlying trend is one of
rapid global
warming (0.27 °C per decade, according to the new Berkeley Earth
Surface Temperature [BEST] dataset).
Since the very
warm surface temperatures of 1998 which followed the strong 1997 - 98 El Niño, the increase in average
surface temperature has slowed relative to the previous decade of
rapid temperature increases, with more of the excess heat being stored in the oceans.
These feedbacks are the primary source of uncertainty in how much the earth will
warm (side note: the question that most climate scientists who study the forcing due to CO2 try to answer is, how much will the long - term globally averaged
surface temperature of the earth rise due to an
rapid rise of CO2 to twice its industrial level, that is, 270 ppm to 540 ppm; it is currently about 380 last time I checked, and rising at ~ 3ppm / year, although this rate of change appears to be accelerating).
There is very high confidence that models reproduce the general features of the global - scale annual mean
surface temperature increase over the historical period, including the more
rapid warming in the second half of the 20th century, and the cooling immediately following large volcanic eruptions...
Not only that, but there is increasingly compelling evidence that the recent short - term slowdown in the
surface temperature record was much less pronounced than previously estimated, if
rapid Arctic
warming is fully reflected, along with potential biases from the changing mix of sea
surface temperature measurement sources in recent years.
The pattern of modeled
surface temperature changes induced by solar variability is well correlated with observed global
warming over the first half of the 20th century, but not with the more
rapid warming seen over the past three decades.
Here I will place 2016 in context, highlighting the role of
rapid Arctic
warming in recent
surface temperature evolution as seen in a comparison of four operational data sets.
Global
warming is the unusually
rapid increase in Earth's average
surface temperature over the past century primarily due to the greenhouse gases released by people burning fossil fuels.
