Global Warming - Coggle Diagram
Global Warming
Social
Positive
Increased temperatures allow for more farming in areas that were previously too cold, thereby making them more habitable and increasing food supply
In the short term farmers are reaping the benefits of earlier springs providing them with a longer crop season. The ability for farmers to produce more also increases food supply in the short term
Increased temperatures globally mean winters are less harsh. This will lower deaths since vulnerable populations will experience less severe symptoms to diseases like the flu. #
Negative
Rising sea levels will lead to forced migration due to cities being flooded. Study claims that by 2100 2 billion people, largely in LEDCs, will be forced to move inland. In 2050 already 700 million will be displaced. The flooding of cities will destroy small business and strip millions of families from income, causing poverty. Additionally coastal farmers will be unable to grow crops due to soil becoming too salty. Science daily estimates 200,000 coastal farmers in Bangladesh will be forced to move because of this, thereby destroying their income and making it harder to access food in an LEDC
Global warming leads to more spreading of infectious mosquito-borne diseases since rising temperatures have increased the amount of habitats that mosquitos can reside in. In Nairobi, a high altitude city in Kenya, malaria is on the rise because global warming has allowed mosquitos to reside in the high altitude city which was previously inhabitable. Studies estimate a 2-3°C increase in temperature would see a 3-5% increase in those at risk of contracting malaria, leading to more deaths.
Climate changes impact of farming capabilities means many coastal farms will become unusable in the near future. Between 2021-2040 studies suggest an additional 8% of the world's population will experience water and food scarcity because of the reduction in coastal farming, leading to more poverty and starvation.
Global warming making colder regions accessible for tropical animals will destroy ecosystems. Therefore, hunting will become harder since animals will become extinct because of foreign and unnatural ecosystems. This will reduce peoples access to healthy non produced meat #
Whilst heat waves may reduce flu season, people who are vulnerable to heat strokes, especially elderly have suffered. In 2003's european heatwave over 70,000 excess deaths occurred according to WHO.
Environmental
Positive
Current global warming trends have forced governments to consider creating a more sustainable world. Many countries are now transitioning towards renewable resources, like Denmark who now are 50% reliant on renewable resources to be more green. Global warming has acted as a wake up call to be more sustainable and consider future generations. #
Negative
Increased temperatures have made colder habitats accessible to tropical animals, thereby ruining the continuity of the ecosystem. Ecosystems have been destroyed as tropical animals destroy local animals' habitats. For example in Australia the humble Bramble Cay melomys, a small rodent species, have disappeared. Experts believe that they become extinct because of climate change's impact on the ocean, leading to an abundance of water at times that destroyed the habitats of these rodents. It is expected that these sort of events will continue to occur, destroying animal ecosystems.
More extreme weather patterns in floods and droughts. Scientists have identified a clear correlation between CO2 emissions and number of natural weather disasters. Scientists predict global warming has doubled the chances of heatwaves similar to the European heatwave of 2003.
12 degree Celsius increase at poles leads to the melting of ice caps --> a positive feedback loop since the warming of earth has lead to the warming of the artic.
According to national geographic Sea ice is melting 14% per decade. As a result polar bears are starving because they cannot access food easily due to disappearing surfaces to walk on. Scientists conducted a study and found one polar lost 44 pounds in just 10 days. Other polar bears have drowned because they swam without ultimately finding a surface to walk on. Scientists project the population of polar bears will reduce by two thirds to 10000 by 2050.
Experts claim that the extreme weather patterns from climate change have the potential to destroy large biomes. For instance as of May 2020 experts foresee that the Caribbean coral reef could disappear in 15 years and the Amazon rainforrest in 50 years
Economic
Positive
The melting of ice caps will open up the northwest passage in the artic, meaning cargo ships can more easily travel and provide supplies internationally. This help globalisation, increasing the economy of the industry of cargo ships.
Warming summers (and winters) increase money in tourism for countries that are colder. Canada predict a 220% increase in tourism by 2100 as a result of warmer temperatures. This will bolster local economies for colder regions as they become more desirable for tourists, thereby improving the life quality #
Attempts to stop climate change like the production of renewable energy is expected to create 24 million new jobs, decreasing the unemployment rate. The fight against it has created new industries that provide opportunities for millions.
Negative
Global warming has melted 40% of ice caps in last 40 years, leading to sea levels to rise. By 2050 over 570 coastal cities are projected to see sea level rises of 0.5 meters. The destruction of cities will destroy local businesses like restaurants thereby increasing unemployment and poverty rate and forcing for the building of more facilities for these people inland
The combination of impacts from global warming are predicted to see a 15% decrease in global GDP by 2100 if countries follow the Paris agreement. If they do not then a 4° global temperature increase will occur leading to over 30% decrease in global GDP (from 2010), worse than the great depression
Because of climate change the number of typhoons and storms have increased, since typhoons form with warmer water, specifically 27°C. This will cause mass economical destruction and also social catastrophe as infrastructure is destroyed. Impacts of tropical storms have already been seen with Hurricane Katrina for example which cost $40 billion in damages.
Industries at highest risk are farming/agriculture, forestry, and fishery. Experts estimate 1.2 billion jobs will be threatened by global warming changes, thereby massively outweighing the positive of 24 million jobs being created and potentially leading to mass unemployment, destroying the economy.
