Sentences with phrase «rate than over the oceans»

Surface temperatures over land regions have warmed at a faster rate than over the oceans in both hemispheres.

Not exact matches

Durack and his colleagues at LLNL found that the Southern Hemisphere's oceans have warmed at a higher rate over the past 35 years than previously thought.

However, for the globe as a whole, surface air temperatures over land have risen at about double the ocean rate after 1979 (more than 0.27 °C per decade vs. 0.13 °C per decade), with the greatest warming during winter (December to February) and spring (March to May) in the Northern Hemisphere.

The former is likely to overestimate the true global SAT trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the SAT over the ocean is predicted to rise at a slightly higher rate than the SST.

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

Either the glaciers would have to flow into the ocean at unrealistic rates, or rapid melting would have to be triggered over a much larger area of the ice sheet than current evidence suggests.

The former is likely to overestimate the true global surface air temperature trend (since the oceans do not warm as fast as the land), while the latter may underestimate the true trend, since the air temperature over the ocean is predicted to rise at a slightly higher rate than the ocean temperature.

I agree that the multimillennial «tail» of the CO2 decay trajectory is relatively unimportant in its own right, but it is not trivial, because it affects the overall rate of decay that includes processes that occur over many decades or a few centuries involving CO2 mixing into the deep ocean and carbonate buffering, and makes them slower than they would be otherwise.

Since the source of anthropogenic global warming is ostensibly increasing concentration of CO2 in the atmosphere, it makes no sense to posit that over time the oceans will warm at a faster rate than the atmosphere above them.

Longer records now available show significantly faster rates of warming over land than ocean in the past two decades (about 0.27 °C vs. 0.13 °C per decade).

Qin Dahe, also co-chair of the working group, said: «As the ocean warm, and glaciers and ice sheets reduce, global mean sea level will continue to rise, but at a faster rate than we have experienced over the past 40 years.»

My opinion expressed elsewhere is that almost all the temperature changes we observe over periods of less than a century are caused by cyclical changes in the rate of energy emission from the oceans with the solar effect only providing a slow background trend of warming or cooling for several centuries at a time.

A question for those with more knowledge than me in the matter: does rainfall over the oceans increase the rate of sea - level rise?

The extra heat in the ocean has caused the sea level to rise 15 mm since November 2014, much faster than the rate of 3 - 3.5 mm per year over recent decades.

Unfortunately, current rates of ocean rise are far slower than what human - caused climate change may set off over the coming decades.

The IPCC's predicted rate of increase in ocean heat content over the past decade or two has proven to be four and a half times greater than the observed rate of increase.

The CO2 doubling response from CM2.6, over 70 - 80 years, shows that upper - ocean (0 - 300 m) temperature in the Northwest Atlantic Shelf warms at a rate nearly twice as fast as the coarser models and nearly three times faster than the global average.

Seawater data collected by a Hydrolab DataSonde (Hach Company, Loveland, CO) since 2000 show that the ocean at this site has undergone a sustained decline in pH over the past decade [2] at a rate that is an order of magnitude greater than expected based on model predictions [13] and the equilibrium response to rising atmospheric CO2 concentration.

This is achieved through the study of three independent records, the net heat flux into the oceans over 5 decades, the sea - level change rate based on tide gauge records over the 20th century, and the sea - surface temperature variations... We find that the total radiative forcing associated with solar cycles variations is about 5 to 7 times larger than just those associated with the TSI variations, thus implying the necessary existence of an amplification mechanism, although without pointing to which one.

Either the glaciers would have to flow into the ocean at unrealistic rates, or rapid melting would have to be triggered over a much larger area of the ice sheet than current evidence suggests.

In addition to this rapid surface warming, the global oceans have also been accumulating heat at an incredible rate - the equivalent of more than two Hiroshima «Little Boy» atomic bomb detonations per second, every second over a the past half century.

What are telling observations against the hypothesis of a largely internally driven imbalance are, on the one hand, the fact the sea level variations are relentlessly positive, irrespective the phase of the PDO, and, on the second hand, the fact that the rate of warming over land is larger than it is over sea (and also that the shallow (0 - 700m) ocean layer never actually cools).

If the rate of sea level rise over the last 20 years is as high or higher than it ever has been over the last 114 year (and is twice the 20th century average), then does this not strongly suggest that there has been no recent slowdown at all in the rate of accumulation of heat by the oceans and cryosphere?
