Climate change is the change in the global climate patternswhich has recently been attributed by the increased levels of atmosphericcarbon dioxide produced by the use of fossil fuels. It is mainly referred to asanthropogenic climate change as people are the main producer of this changingclimate. There is a substantial group of people that vehemently believe thatthe increase in weather related natural disasters is induced by the Earth’schanging climate. On the other hand,some people suspect that we are the maincause of the increase in natural disasters because of have exposed and underprepared we are towards them and alsothe fact that that we are building on land that has a high risk of beingdestroyed by a natural disaster.
It is human’s carelessness that is makingthese disasters worse.It is arguedthat climate change is the defining factor in the increased occurrence of naturaldisasters and most creditable organisations agree with this point. Increasing global temperatures willhave a detrimental effect on the Earth as it will have many consequences thatwill be extensive and hard-hitting. This is due to the fact climate change willcause increased risk of droughts. There will be greater intensity of storms, especiallyin the region bounded by the tropics, specifically storms like hurricanes orcyclones with elevated wind speeds resulting in a more damaging effect on us. Alsoin 2014, climate change caused the heat waves in Australia substantially more probableand life-threatening and in South America, human-induced climate change made heatwaves more intense. A warming climate means that a larger amount of water vapourwill vaporise into the aerosphere and is the main component in storm formation.
).Sea temperatures at the region where Harvey intensified and enlarged were 0.5-1Cwarmer than current-day average temperatures.
There are alternative environmental differences that could make thestorms more fatal. Melting glaciers and ice caps result in additional sea levelrise which will become more substantial over the next decade, which makescoastal flooding more severe when a storm comes ashore. This creates a greateramount of moisture in the air so severe downpours across the world are becomingmore foreseeable.
It’s not just hurricanes and floods that climate change is havingan impact on, it’s exacerbating wildfires too. In California, the exceptionallyhigh temperatures caused years of drought which is left behind a vast amount ofdry vegetation. But, last year intense rainfall occurred leading to the growthvery combustible plants. Then what followed this year was a prolonged period ofextraordinary heat, which was California’s hottest summer ever recorded,reaching temperatures of 106 degrees Fahrenheit in downtown San Francisco. Thehotter temperatures caused the atmosphere to warm up, the air expands and canhold more moisture. This pulls more moisture out of plants, creating drierconditions earlier in the season. The extremely hot temperatures and the strongnortherly winds led to the devastating wildfires that ripped through the state.
This means that without climate change the disaster would have only spread halfas much and would have not caused the devastation that happened.
