The independently - funded group used new modelling to look at the
odds of extreme heat events occurring, with and without man - made emissions.
It is also widely agreed that the world has seen a spate
of extreme heat events in recent years, such as the 2011 Texas heat wave and drought and the deadly 2010 heat wave in Russia, and that global warming made some of these events more likely to occur and more severe.
«Rather striking» climate link to Australian heat waves Because temperature extremes are easier to decipher, scientists are fairly confident that global warming increased the severity and
likelihood of extreme heat events in 2013 in Australia, New Zealand, South Korea, Japan, China and Europe.
Even with the most aggressive mitigation action limiting peak warming close to 1.5 C, there will be substantial damages in the
form of extreme heat events, damages to water resources, and risks to regional food security.
«We know that our temperatures are rising; we're going to be experiencing more hot days but also more extreme humidity days, which tend to be a major
driver of our extreme heat events,» Kelly Muellman, sustainability program coordinator at the city of Minneapolis, told GreenBiz.
Evidence indicates that the human influence on climate has already roughly doubled the
probability of extreme heat events such as the record - breaking summer heat experienced in 2011 in Texas and Oklahoma.
As to what I actually did write, there were two very uncomplicated claims 1) that the Russian summer wheat harvest was done in by heat and attendant drought, which illustrates the entirely uncontroversial fact that heat extremes are not good for agriculture, and 2) that warming on a global average basis anticipates an increased incidence and
severity of extreme heat events, (and decreased incidence and severity of extreme cold events), of which this event was a quintessential example.
In order to see the
effects of extreme heat events on the United States, the researchers developed models to simulate scenarios analogous to that of Europe's for heat - sensitive urban areas.
The European heat wave of 2003 is an example of the
type of extreme heat event lasting from several days to over a week that is likely to become more common in a warmer future climate.
«It appears that parts of Russia are on the cusp of a period in which the
risk of extreme heat events will increase rapidly,» said co-author Martin Hoerling, a research meteorologist, also from ESRL.
The results of Donat and Alexander (2012) lend some credibility to Tamino's comments regarding a lesser change in temperature variance, although they find that an increase in skewness (asymmetry) of the temperature distribution has probably contributed to the increased
frequency of extreme heat events (Figure 5).
«The study shows that aggressive cuts in greenhouse gas emissions will translate into sizeable benefits, starting in the middle of the century, for both the number and the
intensity of extreme heat events,» Dr Tebaldi says.
One of the clearest findings of climate science is that global warming has already dramatically amplified the intensity, duration and frequency
of extreme heat events.
of the temperature distribution has probably contributed to the increased frequency
of extreme heat events (Figure 5).
Climate change has already increased the intensity, duration and frequency
of extreme heat events and will continue to amplify these events in the future.
