As both evaporation rates and heavy rainfall events
increase in a warming world, this lends itself to bigger variations in precipitation.
Given the widely
noted increase in the warming effects of rising greenhouse gas concentrations, it has been unclear why global surface temperatures did not rise between 1998 and 2008.
Over northern continents in winter, however, more precipitation is associated with higher temperatures, as the water holding capacity of the atmosphere
increases in the warmer conditions.
As runoff is also projected to
increase in a warming world, the threat for flooding via heavy rain is likely to increase, putting additional property and farming interests at risk.
Scientific consensus shows that as a result of human activities, GHG concentrations in the atmosphere are at record high levels and data shows that the Earth has been warming over the past 100 years, with the steepest
increase in warming in recent decades.
To explain this finding, the study also showed that while the amount of energy available for
convection increases in a warmer and moister climate, the energy inhibiting convection also increases.
Estimating the exact role of
CO2 increase in the warming of the last 150 years depends on a well - known unknown, namely the amount of warming that would have occurred without the increase in CO2.
A project like helping a researcher track the frequency of dragonfly swarms across the country can help you understand changing environmental conditions, since these swarms tend to
increase in warmer periods.
This is just one of the many «interesting» weather events that we will all have to get used to in the future, as level of water vapor continue to
increase in the warming atmosphere.
Conversely as we «know» that temperatures are warming, if a
step increase in warming occurred, it would be less likely to be thought of as an anomaly, so would not be adjusted.
Such dramatic loss of sea ice could drive
further increases in warming and result in habitat loss for a wide range of species, including polar bears, seals and walruses, one of the authors tells Carbon Brief.
When all of the warming and cooling agents we know of are properly included, the models reproduce the past fairly well and global temperature responds quite proportionally to
increases in warming effects.
Although the current study is limited by the fact that the authors looked only at runoff and held other variables such as land cover constant, the results could be relevant to other regions that are likely to experience
precipitation increases in a warming world.
A recent BBC news story suggested that politicians want a better explanation of a slowdown in the rate of
increase in warming seen in the last 15 years.
The research also shows that the swings in Pacific temperatures tend to
increase in warmer times — like now — but weakened by as much as 50 percent during the protracted cold of the last ice age.
In contrast, statewide warming (Fig. 1C) has led to a
substantial increase in warm conditions, with 80 % of years in 1995 — 2014 exhibiting a positive temperature anomaly (Fig. 2B), compared with 45 % of years in 1896 — 2014 (Fig. 2A).
What is most important, and what was ignored by Stop These Things, is that there would be no
net increase in warming.
If NASA and NOAA were adjusting data to exaggerate the amount of planetary warming, they sure went to an awful lot of trouble and effort to produce only a small
overall increase in warming in the land station data.
To explain this finding, the study also showed that while the amount of energy available for
convection increases in a warmer and moister climate, the energy inhibiting convection also increases.
Because tornado propagation is sensitive to sheer wind and differences between warm and cold air masses meeting, tornado intensity and frequency may
not increase in a warming world.
Modeling studies have projected that CAPE will
increase in a warmer climate leading to more frequent environments favorable to severe thunderstorms in the U.S.. However, they found that the meteorological trends were not due to increasing CAPE but instead due to trends in storm relative helicity, which has not been projected to increase under climate change.
But there is evidence that storminess at lower latitudes — another thing that is expected to
increase in a warming world — will make stable polar vortices less common.
The glacier is currently experiencing significant acceleration, thinning and retreat that is thought to be caused by «ocean - driven» melting;
an increase in warm ocean water finding its way under the ice shelf.
Such a dramatic decline could turn the land from taking up carbon overall to pumping it out by 2100, as the rate of respiration by soil microbes, which exhale carbon dioxide, is predicted to
increase in a warmer world.
