«I am very interested in these wind speed increases and whether they may have also played some role in slowing down the warming at the surface of the ocean,» said Prof Sherwood.

«We have seen a substantial century - to - century variation on these fossil layers,» Anderson reports, «but the monsoon wind strength has increased during the past four centuries as the Northern Hemisphere has warmed.»

So when wind pulls warm water up from down deep, the temperature difference experienced at the interface of the water and ice can effectively submerse the glacier in a hot bath, with some areas experiencing more than a 10-fold increase in melt rate.

Climate modeling shows that the trends of warming ocean temperatures, stronger winds and increasingly strong upwelling events are expected to continue in the coming years as carbon dioxide concentrations in the atmosphere increase.

Over the course of coming decades, though, trade wind speed is expected to decrease from global warming, Thunell says, and the result will be less phytoplankton production at the surface and less oxygen utilization at depth, causing a concomitant increase in the ocean's oxygen content.

Global warming is desiccating the region in two ways: higher temperatures that increase evaporation in already parched soils, and weaker winds that bring less rain from the Mediterranean Sea during the wet season (November to April).

But a handful of studies have warned that warming climate may increase dangerous turbulence along major air routes, and head winds that could lengthen travel times.

The effects of wind changes, which were found to potentially increase temperatures in the Southern Ocean between 660 feet and 2,300 feet below the surface by 2 °C, or nearly 3.6 °F, are over and above the ocean warming that's being caused by the heat - trapping effects of greenhouse gases.

However, extreme events may require the combined effect of increased prevailing winds and tropical storms guided by the strengthened blocking high pressure and nurtured by the unusually warm late - Eemian tropical sea surface temperatures (Cortijo et al., 1999), which would favor more powerful tropical storms (Emanuel, 1987).

That suggests a role for vertical temperature gradients in strengthening winds, such vertical gradients should increase with more global warming.

As we got closer to MK, I started to get warm but I was wary about letting go of my fleece pajama top - the wind was brutal and the temperature wasn't necessarily going to increase by much while we were on the course.

Some heat is being transferred to the deeper ocean by wind changes, reducing the rate of increase in the upper layer, which reduces the warming rate on land.

A recent paper by Vecchi and Soden (preprint) published in the journal Geophysical Research Letters has been widely touted in the news (and some egregiously bad editorials), and the blogosphere as suggesting that increased vertical wind shear associated with tropical circulation changes may offset any tendencies for increased hurricane activity in the tropical Atlantic due to warming oceans.

Much of the recent sea ice loss is attributed to warmer sea surface temperatures with southerly wind anomalies a contributing cause [Francis and Hunter, 2007; Sorteberg and Kvingedal, 2006], with thermodynamic coupling leading to associated increases in atmospheric moisture.»

Hadley Centre climate forecasts are for more high - intensity storms in Britain as global warming intensifies — Scotland has just had the strongest storm in living memory this January, which subsequently hit Scandinavia after increasing its wind - speeds over the North Sea (so it's not just us, it seems).

Thus doubling the solar wind velocity [which is what happens during these solar wind peaks of 500 - 1000 km / s and more increases the dynamic pressure pulse four fold, increases the electrical field - aligned currents, which then increases ionospheric Joule heating which contribute to global warming.

However, global warming models also predict increased winds aloft across the subtropical, hurricane - spawning regions.

However, there are also increases in the upper troposphere / lower stratospheric gradients (due to the stratosphere cooling and the troposphere warming) and that has been shown to lead to increases in wind speeds at the surface.

With respect to 181, if global warming increases sea surface temperatures which contribute to an intensification of tropical cyclones, then storms with winds below hurricane intensity will more frequently attain hurricane status (~ 100 kph winds).

2) Anthropogenic global warming will not affect the Arctic (or any other region) solely by increasing local temperatures, but also by its complex effects on climate as a whole, which includes affects on patterns of wind and ocean currents.

Abstract:... Here we show that a pronounced strengthening in Pacific trade winds over the past two decades — unprecedented in observations / reanalysis data and not captured by climate models — is sufficient to account for the cooling of the tropical Pacific and a substantial slowdown in surface warming through increased subsurface ocean heat uptake.

A further potential climate change connection, which Kevin overlooks, is the impact of a warmer world on the strength of the prevailing winds, and their increase in strength with height.

It simply argues that impacts of changes in wind shear could at least partially offset increases due to warming sea surface temperatures.

Eventually, if not right now, we would expect to see increase in storm intensity and perhaps frequency in a globally warming world, all things being equal... which they are not, since even weathermen can't well predict next week's weather due to some butterfly flapping it's wings in Japan gumming up the wind system.

Seems to me the debate about AGHG global warming and increasing TC frequency / intensity / duration boils down to the fact that as sea surface temperatures, as well as deeper water temperatures rise, the wallop of any TC over warmer seas without mitigating circumstances like wind sheer and dry air off land masses entrained in the cyclone will likely be much more devastating.

If so, this is one way in which global warming may end up causing a decrease in Atlantic hurricane activity over the coming decades, since the increased wind shear over the Atlantic during El Niño events greatly reduces the number and intensity of these storms.»

The article found current CO2 emissions aren't falling rapidly enough to slow global warming largely because most public policy has focused exclusively on developing wind and solar power, which may actually increase emissions.

There is ample evidence in the UK of increasing fuel poverty (i.e., household spending over 10 % of disposable income keeping warm in winter) in the regions of wind farm deployment where higher electricity bills are needed to cover the rent of the land (from usually already rich) landowners, a direct reversal of the process whereby cheap energy over the last century has lifted a significant fraction of the world's poor from their poverty.

His position: • No evidence of increasing lake clarity as a result of secchi measurements since 1946 • The interplay of stratification and plankton productivity are not «straightforward» • Challenges O'Reilly's assumption on the correlation of wind and productivity - the highest production is on the end of the lake with the lowest winds • A strong caution using diatoms as the productivity proxy (it is one of two different lake modes) • No ability to link climate change to productivity changes • More productivity from river than allowed for in Nature Geopscience article • Externally derived nutrients control productivity for a quarter of the year • Strong indications of overfishing • No evidence of a climate and fishery production link • The current productivity of the lake is within the expected range • Doesn't challenge recent temp increase but cites temperature records do not show a temperature rise in the last century • Phytoplankton chlorophylla seems to have not materially changed from the 1970s to 1990s • Disputes O'Reilly's and Verbug's claims of increased warming and decreased productivity • Rejects Verburgs contention that changes in phytoplankton biomass (biovolume), in dissolved silica and in transparency support the idea of declining productivity.

Recent research has yielded insights into the connections between global warming and the factors that cause tornadoes and severe thunderstorms (such as atmospheric instability and increases in wind speed with altitude7, 8).

According to Trenberth the deep ocean is warming due to the action of increasing global winds causing surface heat to move to the deep ocean.

Although there is as yet no convincing evidence in the observed record of changes in tropical cyclone behaviour, a synthesis of the recent model results indicates that, for the future warmer climate, tropical cyclones will show increased peak wind speed and increased mean and peak precipitation intensities.

As sea ice growth increases eastward into the Siberian Arctic (+ ArcSib), strong winds develop that convert an initially cold ocean - ice signal into a warming atmospheric one (Segment II).

The sea ice in the Siberian Arctic is peaking, its effect on the meridional temperature gradient strong, promoting increased zonal flow of large - scale winds, which advect warm air and moisture over the Eurasian continent from the Atlantic and disrupt vertical stratification near the surface and promote high cloudiness, both of which lead to increasing temperatures — greatest at low altitudes and high latitudes.

Solar wind is tied to sunspot activity which may be why, unlike CO2 studies showing a lag between temperature rising and increased CO2 emission, the earth goes through cooling and warming cycles.

Despite this increasing greenhouse gas - induced warming of the oceans, the ocean doesn't warm in a linear manner due to a number of factors, one of these being a natural decadal - scale variation in the way heat is mixed into the oceans by winds - the Interdecadal Pacific Oscillation (IPO).

From the article: A new study released Monday found that warming temperatures in Pacific Ocean waters off the coast of North America over the past century closely followed natural changes in the wind, not increases in greenhouse gases related to global warming.
