With warmer weather occurring over a longer period of time, there is more opportunity for these diseases to spread.
Not exact matches
Otto and her colleagues count how often the
weather event of interest
occurs in a
warmed world compared
with 18th - century Earth.
Accessibility to the dive sites, such as Lighthouse Reef, Turneffe Islands, as well as many excellent sites right off Ambergris Caye, combined
with excellent
weather conditions, clear
warm water, the variety of dive sites and in the unlikely chance that a diving accident should
occur, the hyperbaric chamber is minutes away from any of the dive sites.
Similar negative effects
occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase
with warmer temperatures have been directly linked
with increased rates of respiratory and cardiovascular disease — food production and safety —
warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe
weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
Also, along
with warmer weather, changes in the pattern and intensity of rainfall are already
occuring.
Citing the work of Dr. John Christy and Richard McNider at the University of Alabama in Huntsville (UAH), which compared climate model projections
with temperatures measured independently by satellites and
weather balloons, he said «the average
warming predicted to have
occurred since 1979 (when the satellite data starts) is approximately three times larger than what is being observed.»
«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally
occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and
warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated
with these changes that lead to variations in rainfall and
weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe
weather events worldwide.»»
However,
with all the above stated, this does not mean that climate change is not happening; that human activities have no influence on
weather and climate; nor that global
warming won't
occur in the near future.
Based on temperature records from 1864 to 2002, the odds of such a heatwave
occurring are about 1 in 10 million.4 An event like the 2003 heatwave becomes much more likely after factoring in the observed
warming of 2 °F over Europe and increased
weather variability.5 In addition, comparing computer models of climate
with and without human contribution shows that human influence has roughly quadrupled the odds of a European summer as hot as or hotter than the summer of 2003.6
In their Geophysical Research Letters publication the researchers also write that «aerosol invigoration effect
occurs mainly in
warmed - based convection
with weak shear «-- as they could not find similar effects in frontal convection
weather systems, which have higher wind shear and where air is forced up not by land surface
warming, but by a pushing cold air wedge.

Next — what evidence is there for deep ocean
warming and if it is
occurring how does that communicate

weather to make it extreme?
Scientists project that extreme
weather events, such as heat waves, droughts, blizzards and rainstorms will continue to
occur more often and
with greater intensity due to global
warming, according to Climate Central.
The number of
weather stations recording very
warm night - time temperatures and the frequency
with which these
occur has increased since the mid 1970s.
