Sentences with phrase «rate of surface warming since»

Not exact matches

In June 2015, NOAA researchers led by Thomas Karl published a paper in the journal Science comparing the new and previous NOAA sea surface temperature datasets, finding that the rate of global warming since 2000 had been underestimated and there was no so - called «hiatus» in warming in the first fifteen years of the 21st century.

For global observations since the late 1950s, the most recent versions of all available data sets show that the troposphere has warmed at a slightly greater rate than the surface, while the stratosphere has cooled markedly since 1979.

It gives a rate of warming of some 0.07 degrees C / decade and a total rise in surface temperature of some 0.4 degrees C since 1944.

Since OHC uptake efficiency associated with surface warming is low compared with the rate of radiative restoring (increase in energy loss to space as specified by the climate feedback parameter), an important internal contribution must lead to a loss rather than a gain of ocean heat; thus the observation of OHC increase requires a dominant role for external forcing.

We've been adding carbon dioxide from fossil fuels to the atmosphere at increasing rates since the dawn of the Industrial Era, and the result has been a steady warming of the planet's surface.

Global warming does not mean no winter, it means winter start later, summer hotter, as Gary Peters said «The global average surface temperature has risen between 0.6 °C and 0.7 °C since the start of the twentieth century, and the rate of increase since 1976 has been approximately three times faster than the century - scale trend.»

The problem here is that estimates of changes in sea surface temperature and the depth of the warm mixed layer might be very unreliable, since the general behavior of the Atlantic circulation is only now being directly observed — and the most recent findings are that flow rates vary over a whole order of magnitude:

They conclude that while the rate of increase of average global surface temperatures has slowed since 1998, melting of Arctic ice, rising sea levels, and warming oceans have continued apace.

But if you take a look just at surface - atmospheric warming by itself, you do see a bit of a tapering off in the * rate * of warming since ~ 2000.

Since the average lapse rate is -7 K per km, and the typically radiative surface in the atmosphere is at about 5 km, the surface temperature will be 5 x 7 = 35 K warmer than it would be in the absence of GHGs.

Since the increase in the rate of heat sequestration (and the concomitant reduction in the rate of surface warming) likely is mainly a result of cyclical internal variability, when the cycles will switch to the opposite phase, the surface warming will resume even faster.

The oceans have warmed with «virtual certainty,» the report concludes, at a rate of about 0.2 degrees Fahrenheit (0.11 Celsius) per decade since 1970 in the upper 246 feet (75 meters) of surface water.

Since the surface is not the climate system as a whole, only a small part of it, inter-decadal variability in the rate of surface warming can not be used as the basis for strong claims about climate sensitivity.

Five - year averaging reduces differences among temperature datasets, showing that since the mid-1970s the global surface air temperature has on average increased by 0.1 °C every five to six years, although the rate of warming, viewed from a five - year perspective, has not been steady.

Since the ocean surface warms overall at about only half the rate of the land surface (due to the larger thermal inertia), it is to be expected that the lower troposphere wouldn't warm as fast as the global surface average.

The historical trend since 1979 is heavily influenced by the recent slowdown in the rate of surface warming which is likely to be the result of natural variability overprinting the forced trend.
