Sentences with phrase «atmospheric warming pattern»

Furthermore, the missing hotspot in the atmospheric warming pattern observed during the last warming period proves that (1) the IPCC climate theory is fundamentally broken, and (2) to the extent that their theory correctly predicts the warming signature of increased carbon dioxide, we know that carbon dioxide definitely did not cause the recent warming (see here for my full explanation of the missing hotspot).

For example, in Earth atmospheric circulation (such as Hadley cells) transport heat between the warmer equatorial regions to the cool polar regions and this circulation pattern not only determines the temperature distribution, but also sets which regions on Earth are dry or rainy and how clouds form over the planet.

The pattern of warming in the last 150 years can not be explained by increases in atmospheric CO2.

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

That study, also detailed in Geophysical Research Letters, suggests that while the Pacific heat set the atmospheric pattern in motion, Arctic sea ice loss in a particular region made the warm / cold difference so extreme, said Jennifer Francis of Rutgers University.

Francis, who wasn't involved with either study, is one of the main proponents of an idea that by altering how much heat the ocean lets out, sea ice melt and Arctic warming can also change atmospheric circulation patterns, in particular by making the jet stream form larger peaks, or highs, and troughs, or lows.

E. Even the official «global temperature» record, which has been adjusted to promote global warming hysteria, has not followed the pattern of increased atmospheric concentrations of CO2, but rather has followed the pattern of natural causes, primarily solar activity and ocean cycles.

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.

As I have also noted in recent public comments, additional mechanisms have been identified by which changes in atmospheric circulation patterns that may be a result of global warming could be affecting droughts in the American West.

Increased weed and pest pressure associated with longer growing seasons and warmer winters will be an increasingly important challenge; there are already examples of earlier arrival and increased populations of some insect pests such as corn earworm.64 Furthermore, many of the most aggressive weeds, such as kudzu, benefit more than crop plants from higher atmospheric carbon dioxide, and become more resistant to herbicide control.72 Many weeds respond better than most cash crops to increasing carbon dioxide concentrations, particularly «invasive» weeds with the so - called C3 photosynthetic pathway, and with rapid and expansive growth patterns, including large allocations of below - ground biomass, such as roots.73 Research also suggests that glyphosate (for example, Roundup), the most widely - used herbicide in the United States, loses its efficacy on weeds grown at the increased carbon dioxide levels likely to occur in the coming decades.74 To date, all weed / crop competition studies where the photosynthetic pathway is the same for both species favor weed growth over crop growth as carbon dioxide is increased.72

According to Gerry Bell, Ph.D., NOAA's lead seasonal hurricane forecaster, the major climate factors expected to influence this year's activity are the ongoing multi-decadal signal, which produces wind and atmospheric pressure patterns favorable for hurricane formation, along with ongoing warmer - than - normal sea surface temperatures.

According to research published last week by Jennifer Francis of Rutgers University (Geophysical Research Letters, vol 39, L06801), the rapid warming in the Arctic is affecting atmospheric circulation further south, making weather patterns more persistent — more blocking, in other words — which makes some kinds of extreme weather, such as heatwaves, more likely.

The observed patterns of surface warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).
