It weather attributing to the increased likelihood of weather-related

It is argued
that climate change is the defining factor in the increased occurrence of natural
disasters and most creditable organisations agree with this point. “Climate change played a role in 14 of
28 storms, droughts, and other 2014 extreme weather events investigated by
global scientists”(National Geographic). “Recent global industrialisation
has resulted in average worldwide temperatures increasing by 0.8 degrees
Celsius in the last century” (Board of atmospheric sciences and climate).
Increasing global temperatures will have a detrimental effect on the Earth as
it will have many consequences that will be extensive and hard-hitting. This is
due to the fact climate change will cause increased risk of droughts, in 2014; “climate
change worsened a drought in Eastern Africa and in the Levant region of
southern Syria.”(National Geographic).There will be greater intensity of storms,
especially in the region bounded by the tropics, specifically storms like hurricanes
or cyclones with elevated wind speeds resulting in a more damaging effect on
us. According to NASA, “changes in climate will also affect extreme
temperatures meaning a greater probability of record hot weather attributing to
the increased likelihood of weather-related natural disasters.” Also in 2014,
climate change caused the heat waves in Australia substantially more probable
and life-threatening and in South America, human-induced climate change made “Argentina’s
heat wave five times more likely.”(National Geographic) A warming climate means
that a larger amount of water vapour will vaporise into the aerosphere and is
the main component in storm formation. “If we are creating an atmosphere more
loaded with humidity, any storm that does develop has greater potential to
develop into an intense storm,” says Tselioudis. “Warming that has already occurred
since 1980 has increased sea surface temperatures 0.3 degrees Celsius, which
should increase the maximum potential wind speed of hurricanes by at least 1
knot” (NASA, according to hurricane intensity models). Sea temperatures at the region
where Harvey intensified and enlarged were 0.5-1C warmer than current-day
average temperatures, which means 3-5% more moisture in the atmosphere. There are alternative environmental differences
that could make the storms more fatal. Melting glaciers and ice caps result in additional
sea level rise which will become more substantial over the next decade, which
makes coastal flooding more severe when a storm comes ashore. In their 2001
report, the IPCC stated that “sea levels will rise 0.11 to 0.77 meters by 2100.”
This creates a greater amount of moisture in the air so severe downpours across
the world are becoming more foreseeable. For example, “in Houston they have become
167 percent more frequent in the past decade” (according to vox.com). It’s not
just hurricanes and floods that climate change is having an impact on, it’s
exacerbating wildfires too. In California, the exceptionally high temperatures
caused years of drought which is left behind a vast amount of dry vegetation.
But, last year intense rainfall occurred leading to the growth very combustible
plants. Then what followed this year was a prolonged period of extraordinary heat,
which was California’s hottest summer ever recorded, reaching temperatures of
106 degrees Fahrenheit in downtown San Francisco. The hotter temperatures
caused the atmosphere to warm up, the air expands and can hold more moisture.
This pulls more moisture out of plants, creating drier conditions earlier in
the season. The extremely hot temperatures and the strong northerly winds led
to the devastating wildfires that ripped through the state. Climate change was
the main cause of this wildfire as a study found that “climate change due to
human activity accounted for roughly 55 percent of the aridity in Western US
forests between 1979 and 2015” (Dr John Abatzoglou). This means that without
climate change the disaster would have only spread half as much and would have
not caused the devastation that happened.
