The effects of climate changePosted: November 29, 2015
The more the climate is changing the more severe the weather is getting. The Intergovernmental Panel on Climate Change (IPCC) reports the number of hurricanes or tropical storms hasn’t increased in the past 40 years, but the intensity of them has gotten for worse due to warmer weather and higher sea levels. This results is rougher coastal storms, more storm damage, more fooding, and many more. The Increase in heatwaves and drought are causing a number of problems. Forests are drying up and become vulnerable to forest fires, livestock is affected and the melting of the Arctic ice.
Both the Artic ice sheets and Greenland ice sheets are melting, and it is estimated that if global temperatures rise by somewhere between 1.9 and 4.6 degrees complete melting would lead to a sea level rise of around 6-7m. A rise of this magnitude would threaten coastal area with 23% of the worlds’ population living near coastal zone. If current warming trends are allowed to continue, London, Bangkok and New York, Shanghai and Mumbai will be among a number of cities which will eventually end up below sea level. More info
Climate change will also have an impact on our health mostly in a negative way. An increase in malnutrition, increase in the frequency of cardio-respiratory diseases from changes in air quality, increase in the number of people suffering from death, disease and injuries from extreme weather events. Another concern is contaminated water. dirty runoff from flooding can result in dirty water contaminating our drinking water, and higher levels of salt caused by rising seas levels, are infecting fresher water. Flooding and droughts, can impact how people gain access to food. If the amount or quality of foods available decreases, malnutrition tends to increase, as well as the chance of infectious disease.
The more intense storms, floods, forest fires, and earth quakes, as a result of climate change, are cost us financially, for example the damage caused by the wildfires in Canberra, Australia in 2003, cost 260 million dollars, or the estimated 150 billion dollar cost of cleaning up the damage caused by Hurricane Katrina in New Orleans ten years ago. More recent estimates of the impact of a 66 cm sea level rise by 2100 suggest costs could be in the region of US$ 236 billion, with nearly 9000 square kilometers of land having to be abandoned and 13,000 km of coastal defences needing to be constructed. Needless to say many poorer countries do not have these resources. It is some of the poorer, undeveloped countries and small islands that will be effected the most by Climate backlash, More info
Climate change won’t only have an effect on us, but it will have a massive influence on our ecosystem. From the start of time the earths ecosystem has adapted in response to climate changes, like shifts in temperature, land available, and differences in rainfall, but because climate change is happening so quickly it’s likely that many species won’t be able to adapt in time, and ecosystems could be transformed entirely in the future.
The IPCC estimates that if earth experiences a global temperature rise of 2.9 to 4.1 degrees fahrenheit that 18 to 24 percent of animal and plant species will go extinct.
Both on land and underwater life is at risk. Species that are going to be more greatly effected are thous that migrate, mainly birds, this is due to they’re dependance of the climate of the seasons. More info
Underwater life is at great risk, with increasing water temperature and increasing levels of carbon dioxide. As mentioned before, oceans are incredible carbon sinks, but If these levels of carbon continue to increase, so does the risk to sea life. Both the Coral Reef and Great Barrier Reef are at risk due to being sensitive to the temperature of water, and if species like coral where to become endangered, or even extinct, it would have a enormous affect on the eco-system, as sea life depends on it for food and inhabit.
