Sadly, some believe that global warming is not that big of a deal. The reality is that global warming is causing major climate throughout the world and its rate of progression is not going to slow if something is not done . Global warming affects our climate, our environment, other habitats around the world, and it even has negative effects on our agriculture. In fact eleven percent of the world’s population is currently vulnerable to climate change impacts such as droughts, floods, heat waves, extreme weather events and sea-level rise.
And it seems as if the effects of global warming are only getting worse as time goes on.
Moreover, something needs to be done to slow global warming done to keep our planet from being destroyed. Our climate is changing more and more due to global warming. The average temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Oceanic and Atmospheric Administration. 1.4 degrees may not seem like much, but it really does have horrible effects on our environment.
According to NASA, 16 of the 17 warmest years on record have happened since 2001. In a study of heat stress conditions at 187 weather stations across the u.s.Crustaceans recorded 12 more days of extreme heat per year from 1949 to 2005 on average.
This goes to prove that global warming is actual causing the earth to become hotter. Still we continue to burn fossil fuels and clear trees that absorb carbon dioxide, sending heat-trapping gases into the atmosphere. This will only cause the Earth to continue to rise in temperature; eventually leading to the earth being uninhabitable.
As the world’s population continues to grow more food and other resources are needed. Moreover, as global warming causes the world gets hotter, farmers find themselves having difficulties with growing healthy crops. Greenhouse gases in the Earth’s atmosphere trap heat on the planet, keeping the surface warm enough for life to exist.
In addition when the atmosphere begins to be filled with too many greenhouse gases the temperature becomes too hot, plants begin to die. Global warming causes the increase in pests and insect population, harming crops like, Soybean, wheat, corn. Although warmer temperatures create longer growing seasons and faster growth rates of plans it also increases the metabolic rate and number of breeding cycles of insect populations. Global warming also causes changes in atmospheric carbon dioxide and ground level ozone concentration. Added heat stress, shifting monsoons, and dryer soils May reduce yields by as much as a third in the tropics and subtropics, where crops are already near their maximum heat tolerance (UNEP).
Global warming has the potential to cause extinctions in the majority of the World’s vulnerable ecosystems. One of those equals ecosystems is the Arctic; home of the polar bears. Due to global warming the Arctic is warming twice as fast as the rest of the world, meaning there is less ice on which the Bears can roam. At a rate of about 9% per decade the ice caps have decreased in thickness by more than 40% since the 1960s. Avi cat become smaller and smaller do polar bears are forced to migrate closer to human settlements. By the year 2040 the ice caps are estimated to be free of ice if this rate of temperature rise continues.Global warming is not only affecting habitats on land but also habitats off land. 169 Marine areas have been identified as dead zones as of 2008 — up from 44 in 1995 (WRI). One of the largest was estimated to be the size of Massachusetts.
In just a few decades, global warming has affected the earth in so many ways. Despite of all the negative effects of global warming and all of the horrible effects that it has on our climate, some people just don’t seem to care. We still continue to pollute our oceans, burn fossil fuels cut down trees and create harmful waste products. The truth is that global warming is a serious topic and at this rate it may lead to the demise of many plant and animal species on our Earth.
