Since deeper waters will be warmer, there is a possible link to the global ocean circulating currents that results in warmer water in polar regions.

New Zealand is in the South Pacific region as defined by American, so from the Contiguous 48 states in the U.S., you'd have to first book a Middle East award and then tack on a Europe to South Pacific award since the U.S. to South Pacific award is only valid when flying via the Pacific Ocean.

Goin» Off Safaris has been showcasing the region's unique aquatic activities since 2005, including swimming encounters with Australian sea lions, Bottlenose Dolphins and cage diving with the oceans most formidable predator, the great white shark.

Since the subtropical oceans are favoured regions for low clouds (Figure 2), especially in summer, such changes in weather patterns may conceivably affect low cloud cover in the manner seen in Figure 1.»

The long - wave radiation estimated for surface temperatures is pretty clear that forcing is occuring near the equator and since the ocean in this region is acccumulating heat that will eventually re-emerge the deeper it can be sequestered the better.

Still, the scientists, at the National Snow and Ice Data Center in Boulder, Colo., said that the extent of the ice in the Arctic this summer was 33 percent smaller than the average extent tracked since satellites started monitoring the region in 1979, and that the long - term trend is toward an ice - free summer in the Arctic Ocean within a few decades.

In a region where the ocean was already being heated, the same pattern would be seen but now since the skin SST was warmer, the skin - bulk difference would increase, causing more heat to go into the ocean.

Since the darker ocean surface absorbs more sunlight than the bright ice, this warms the region even further.

The team estimate that the extent of warming in the southern hemisphere oceans since 1970 could be more than twice what has been inferred from the limited direct measurements we have for this region.

Since the different regions of the ocean where Argo floats operate are not at the same temperature, then multiple instruments operating in different areas do not serve to reduce uncertainty, true.

Since the whole world does not appear to freeze during a ice age, the must be massive ice making going at the pole driven by heat lifting oceans of water to the sky from the equator where it is pushed by the expanding air and vapor to the poles areas where it returns to the surface and follows cold land like a culvert between warmer expanding ocean air back down to the equatoral region.

«A peer - reviewed paper [Krivova et al.] published in the Journal of Geophysical Research finds that reconstructions of total solar irradiance (TSI) show a significant increase since the Maunder minimum in the 1600's during the Little Ice Age and shows further increases over the 19th and 20th centuries... Use of the Stefan - Boltzmann equation indicates that a 1.25 W / m2 increase in solar activity could account for an approximate.44 C global temperature increase... A significant new finding is that portions of the more energetic ultraviolet region of the solar spectrum increased by almost 50 % over the 400 years since the Maunder minimum... This is highly significant because the UV portion of the solar spectrum is the most important for heating of the oceans due to the greatest penetration beyond the surface and highest energy levels.

His theory is, that the sea surface has been warming since the little ice age, and ocean air also warmed coastal and other ocean air affected regions, but not OAS regions.

Slow variations in upper ocean heat content that have been observed in the subpolar and marginal ice zone regions of the Atlantic since the mid-twentieth century are thought to be related to changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

The cooling of the Arctic since 1950 - 60 has been most marked in the very same regions which experienced the strongest warming in the earlier decades of the 20thC, namely the central Arctic and northernmost parts of the two great continents remote from the world's oceans, but also in the Norwegian - East Greenland Sea....

Since Greenland is near the end of the path for the Gulf Stream and most of the water vapor in the atmosphere in that region is from the Gulf Stream, ice cores from Greenland are a good indicator of the ocean temperatures in the north Atlantic Oocean temperatures in the north Atlantic OceanOcean.

Since the northern Atlantic Ocean is one of the main areas that the AMO is active (meaning that area of the ocean is what warms up) it is hardly surprising that arctic ice in that region is impaOcean is one of the main areas that the AMO is active (meaning that area of the ocean is what warms up) it is hardly surprising that arctic ice in that region is impaocean is what warms up) it is hardly surprising that arctic ice in that region is impacted.

In a ground - breaking new paper (Lansner and Pepke Pedersen, 2018) published in the journal Energy and Environment, an analysis of land surface instrumental records from across the globe's ocean air sheltered (OAS) regions reveals that, like the proxy evidence presented above, most of the modern era warming occurred prior to the 1940s, and the there has effectively been no net warming since then.

Since then, atmospheric CO2 declined as the Indian and Atlantic Oceans have been major depocentres for carbonate and organic sediments while subduction of carbonate - rich crust has been limited mainly to small regions near Indonesia and Central America [10], thus allowing CO2 to decline to levels as low as 170 ppm during recent glacial periods [11].

Since ocean temperature anomalies in the canonical Niño 3.4 region are now above 2 C — which are record values for the calendar month and not too far from their highest values ever observed at any time of year — current observations in the real world suggests that the models are very much on track.

Since that time the Indian and Atlantic Oceans have been the major depocenters for carbon, with subduction of carbon - rich crust limited mainly to small regions near Indonesia and Central America [47].

And it was in 1988 that James Hansen decided to present the case that this slow warming since the LIA was soon to become «unprecedented» due to CO2 emissions, thus causing untold climate chaos - i.e. boiling oceans, droughts, famines, Manhattan Island flooding along with other coastal regions, Earth turning into the next Venus, and etc..
