Not exact matches

Velicogna and her colleagues also measured a dramatic loss of Greenland ice, as much as 38 cubic miles per year between 2002 and 2005 — even more troubling, given that an influx of fresh melt water into the salty North Atlantic could in theory shut off the system of ocean currents that keep Europe relatively warm.

The warm waters give up their heat in the bitterly cold regions monitored by OSNAP, become denser, and sink, forming ocean - bottom currents that return southward, hugging the perimeter of the ocean basins.

Lead author, Dr Michael Singer from School of Earth and Ocean Sciences at Cardiff University, said: «In drylands, convective (or short, intense) rainfall controls water supply, flood risk and soil moisture but we have had little information on how atmospheric warming will affect the characteristics of such rainstorms, given the limited moisture in these areas.»

Understanding how carbon flows between land, air and water is key to predicting how much greenhouse gas emissions the earth, atmosphere and ocean can tolerate over a given time period to keep global warming and climate change at thresholds considered tolerable.

As the warm water reaches high North Atlantic latitudes, it gives up heat and moisture to the atmosphere, leaving cold, salty, dense water that sinks to the ocean floor.

Many of these large mammals migrate back to the warm Pacific Ocean waters of Banderas Bay for the winter months to feed, mate or give birth and include, among others:

Regardless, I would posit the worsening winter ice formation is as expected given the poles suffer first and winters warm faster than summers, BUT that this is happening within two years of the EN peak, which was my time line in 2015, one wonders if the combination of warm EN - heated Pacific waters (oceans move slowly) and warm air are a trailing edge of the EN effect OR this is signallibg a phase change driven by that EN, or is just an extreme winter event.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Think of what would happen if you could pump cold deep water up to the surface, increasing the air / sea temperature gradient and warming the water; that would give you an anomalously large ocean heat uptake.

The oceans gave up their last big bank of warm water last fall.

Corresponding time for surface + tropospheric equilibration: given 3 K warming (including feedbacks) per ~ 3.7 W / m2 forcing (this includes the effects of feedbacks): 10 years per heat capacity of ~ 130 m layer of ocean (~ heat capacity of 92 or 93 m of liquid water spread over the whole globe)

The picture I gave neglects the effect of ocean dynamics — cooling by upwelled water entering the mixed layer and warming by imported warm water from the side.

(I think that an anomalously warm ocean surface heated from below would lead to more evaporation, and the additional water vapor would give a positive greenhouse effect that would partially offset the effect of a drop in greenhouse gas concentrations.)

Taking water out of this, i.e., leaving the practically 100 % nitrogen and oxygen ocean of gas, this blanket warming would give a temp of 67 °C.

El Niño is the name assigned when shifting trade winds over the Pacific Ocean give rise to warmer water temperatures further east, fomenting stormy conditions in parts of the Americas and concomitant droughts in parts of Asia and Australia.

Scientists in New York are blaming global warming for upsetting the Nenana Ice Competition stating that a recent navel survey clearly indicated that the heat energy that would normally cause the river to release its life giving waters to the downstream environment had been redirected to deep ocean sequestation where it was being used by the oil industry to kill sharks.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

The relevant factor may therefore not be how warm the water is in a given ocean basin, but how warm it is relative to other ocean basins.

Just one question Jarvis, how will giving Greenpeace money change the Arctic temperature, or change the ocean currents such that warmer waters don't reach the Arctic?

Other feared effects — such as the sudden release of large volumes of methane from thawing Arctic tundra or the disruption of the Atlantic Ocean currents that carry warm water into the northern latitudes — were given a low chance of occurring on a rapid scale.

An interesting paper has now been issued which shows support for the idea that the oceans and not the greenhouse effect are responsible for warming (and by implication) cooling of the atmosphere thereby giving some mainstream credence to my Hot Water Bottle Effect.

Scientists have uncovered more evidence for a dramatic weakening in the vast ocean current that gives Britain its relatively balmy climate by dragging warm water northwards from the tropics.

In the face of climate change and ocean warming, this study gives managers hope that maintaining high water quality can spare corals.»

As the warm water reaches high North Atlantic latitudes, it gives up heat and moisture to the atmosphere, leaving cold, salty, dense water that sinks to the ocean floor.

Hurricanes can be thought of, to a first approximation, as a heat engine; obtaining its heat input from the warm, humid air over the tropical ocean, and releasing this heat through the condensation of water vapor into water droplets in deep thunderstorms of the eyewall and rainbands, then giving off a cold exhaust in the upper levels of the troposphere (~ 12 km / 8 mi up).

Soon, the mathematics of the UCSB researchers will help reveal that given differences in ocean temperature, for example, in an especially a real world example of the Earth rotating on its axis with warm water at the bottom of an ocean of colder water on the top, that the cold water will sink.

Though polar amplification — which is another term for how global warming spurs the poles to heat up faster than the rest of the world — helped to generate the upper level features in the atmosphere that would consistently generate storms running across the U.S. East Coast, widespread warmer than normal ocean waters helped to give these storms more fuel.
