So the report notes that the current «pause» in new global average temperature records since 1998 — a year that saw the second strongest El Nino on record and shattered warming records — does not reflect the long - term trend and may be explained by the oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

Covering nearly 5.5 million square miles, the frozen mass exerts an enormous influence on the global climate, reflecting sunlight back into space and cooling Earth's atmosphere and oceans.

Ocean temperatures experience interannual variability and over the past 3 decades of global warming have had several short periods of cooling.

The main point is that just as surface temperatures has experienced periods of short term cooling during long term global warming, similarly the ocean shows short term variability during a long term warming trend.

Cooling sea - surface temperatures over the tropical Pacific Ocean — part of a natural warm and cold cycle — may explain why global average temperatures have stabilized in recent years, even as greenhouse gas emissions have been warming the planet.

Given how much yelling takes place on the Internet, talk radio, and elsewhere over short - term cool and hot spells in relation to global warming, I wanted to find out whether anyone had generated a decent decades - long graph of global temperature trends accounting for, and erasing, the short - term up - and - down flickers from the cyclical shift in the tropical Pacific Ocean known as the El Niño — Southern Oscillation, or ENSO, cycle.

Numerous denier arguments involving slight fluctuations in the global distribution of warmer vs cooler sea surface areas as supposed explanations of climate change neglect all the energy that goes into ocean heat content, melting large ice deposits and so forth.

-- The combined global land and ocean average surface temperature for the December — February period was 0.41 °C (0.74 °F) above the 20th century average of 12.1 °C (53.8 °F), making it the 17th warmest such period on record and the coolest December — February since 2008.

What happens to global temperature trends when you factor in the potentially confounding influence of ocean warming and cooling cycles?

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

I particularly enjoyed the slides that, when combined (1) provided an overview of hotter and cooler CO2 molecules as it relates to how they are seen from outer space and from profile — because this will make it easier for me to explain this process to others; (2) walked through the volcanic and solar activity vs assigning importance to CO2 changes — because this another way to help make it clearer, too, but in another way; (3) discussed CO2 induced warming and ocean rise vs different choices we might make — because this helps point out why every day's delay matters; and (4) showed Figure 1 from William Nordhaus» «Strategies for Control of Carbon Dioxide» and then super-imposed upon that the global mean temperature in colors showing pre-paper and post-paper periods — because this helps to show just how far back it was possible to make reasoned projections without the aid of a more nuanced and modern understanding.

The Mg / Ca estimates of tropical ocean cooling would be nearly impossible to reconcile with a global sensitivity of 2.3 degrees.

Dr. Easterbrook spoke of his studies of solar activity and ocean cycles and his prediction that a decades - long global cooling spell was coming, deeper than the one in the middle of the 20th century.

«Since the ocean component of the climate system has by far the biggest heat capacity», I've been wondering if the cool waters of the deep ocean could be used to mitigate the effects of global warming for a few centuries until we have really depleated our carbon reserves and the system can begin to recover on its own.

My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years on Earth with global average land and ocean surface temperature anomaly below 1C above pre-industrial average (using 1850 - 1900 proxy).

Re # 35: «Pielke believes ocean heat content changes are the most reliable metric for assessing global heating and cooling.»

IF cool deep sea water were mixed relentlessly with surface water by some engineering method --(e.g. lots of wave operated pumps and 800m pipes) could that enouromous cool reservoir of water a) mitigate the thermal expansion of the oceans because of the differential in thermal expansion of cold and warm water, and b) cool the atmosphere enough to reduce the other wise expected effects of global warming?

Redistribution of heat (such as vertical transport between the surface and the deeper ocean) could cause some surface and atmospheric temperature change that causes some global average warming or cooling.
