A new report from the Intergovernmental Panel on Climate Change has detailed described the impact of climate change on planet Earth. It found that if global temperatures are to stay below 1.5 degrees Celsius (C) and to avoid dangerous consequences, nations would need to drastically reduce their anthropogenic carbon dioxide emissions by 2030.
Five key risks are identified in the report. These include heat drought, coastal flooding and storm surges as well as sea level rising. Below, you can see the severity of the risk at various levels. Darker colors indicate greater stress levels.
The physical effects of climate change are not the only ones. There are also socioeconomic consequences. As an example, people may be more likely to be evacuated due to the increased likelihood of tropical cyclone and flood surges. This will lead to more deaths from climate extreme events. The report also found that the population at risk of coastal climate hazards will grow to a billion people by 2050.
While many of the impacts of climate change are already occurring, the report notes that the impacts are far larger than previously reported. Many species have had their ranges changed, with half of all land animals and plants shifting to areas more conducive for survival.
Climate change has not only altered the ecosystems but also made it difficult to access food and water. As a result, millions of people are suffering acute food insecurity. Additionally, increasing temperatures and storminess are reducing the availability of water resources. A similar trend is observed in the displacement of more than eight million people worldwide due to natural disasters.
More than eighty percent of terrestrial animals are currently at risk of extinction. This figure is projected to increase to 13 per cent at three degrees Celsius, and to 15 per cent at four degrees Celsius. A higher chance of regional extinctions also exists.
Rising sea levels will increase flooding and could cause major cities to run out of water. At the same, the oceans are warming which could lead to hypoxia. This will reduce the ability of marine microbes to absorb oxygen. Further, more greenhouse gases will be released into the atmosphere by the melting Arctic permafrost.
Drought is another major threat to agriculture. A drought in agriculture is more likely at two degrees. It's expected to increase by 150-2000%. Agricultural yields are also expected to decrease by 5 to 10 percent. It could result in the loss of vital nutrients such as zinc, depending on how much carbon dioxide is released into our atmosphere.
Climate change can also have an impact on the availability of zinc, iron, and protein. According to research, a carbon equivalent increase in atmospheric CO2 could reduce zinc by 7%. A CO2 equivalent increase in protein will also lower it by 4%.
These conclusions are based on data from five climate models around the world. These findings are compared with two emission scenarios, a low and high scenario. Each one outlines different ways to reach macro-level conditions by 2030.
FAQ
How are extreme weather events related to climate change?
Global warming directly links extreme weather events like heat waves, floods. droughts. cyclones. storms. Global warming has contributed to an increase in the atmospheric temperature.
Climate scientists claim that the frequency of extreme weather related disasters has more then doubled since 1980. As sea temperatures rise, so do wind patterns. This impacts the normal distribution of storms or hurricanes in different areas across the globe.
The 2015 El Nino event brought warm water toward South America. It caused alarmingly high temperatures and heavy rains, which led to flooding in Peru. These floods resulted in displacement of people and property destruction. Several places including Antarctica have recorded their highest-ever temperatures indicating a definite relation between global warming trends and the occurrence or frequency of extreme weather events around the world.
Another example of climate change at work is Hurricane Irma. It was a major storm that struck Florida in 2017, causing economic losses of $50 billion.
The Intergovernmental Panel on Climate Change's (IPCC) concluded, "Human activities are increasing the severity current climate change." This naturally leads worldwide to more severe, intense, and frequent natural disasters. There is strong evidence of humans' involvement with extreme weather events occurring frequently around us all.
How does human activity contribute to climate change?
Climate change is a major contributor to human activity. According to the Intergovernmental Panel on Climate Changes (IPCC), more than 70% global warming has been caused by humans since the middle of the 20th century.
Carbon dioxide is released into the atmosphere by burning fossil fuels like oil, coal, and gas. This adds to already existing levels of atmospheric CO2, which act as a "greenhouse gas" by trapping heat from the sun in Earth's atmosphere and increasing temperatures even further. As Arctic ice melts, this causes ocean levels to rise and can cause severe weather patterns all over the globe, including floods, droughts and storms that could lead to food shortages.
Deforestation: Deforestation knocks out trees which sequester atmospheric carbon dioxide in their trunks when they take it up during photosynthesis. Deforestation also raises albedo (the amount of reflected solar radiation that is returned into space) and reduces solar heat absorption by earth's surface, thereby promoting global warming. Also, deforestation can lead to a decrease in local air quality and respiratory problems.
Farming is responsible for 14% to 18% of all anthropogenic greenhouse emissions globally each year. Animal waste releases large amounts of methane gas into the atmosphere due to its composition rich in methane bacteria Eating less or no animal products altogether can be an effective way to reduce your contribution towards global warming from this source alone., Agriculture itself also relies heavily on fertilizers which contain nitrous oxide released into our atmosphere directly harms humans creating smog from ground level ozone harming our respiratory system making polluted air hazardous for life.
In conclusion, while human activity has had an adverse impact on our environment for centuries, technological advances have made it possible to turn our attention towards the future. We can leverage technology through green innovation to help us move forward in our efforts to reduce climate change and keep everyone safe.
What is the effect of climate change upon biodiversity and ecosystems?
Climate change has many effects on biodiversity and ecosystems. Climate change is affecting ecosystems and wildlife today.
These shifts in climate conditions can cause shifts in habitat areas, disrupt food chains or affect population numbers or species distributions, with potentially dramatic consequences for biodiversity and the functioning of ecosystems. Hydrological changes can also impact water availability for aquatic species.
Climate change can also lead to rising temperatures and more extremes, such as droughts or floods. This places more strain on already fragile systems like coral reefs, tropical rainforests, and other ecosystems. Climate change could lead to the extermination of up to 30% of animal species by 2050. This would cause further ecological community losses.
Climate change is therefore a considerable threat not only to biodiversity but also to human societies that depend on functioning ecosystems for food, fresh water, timber, and other services. It is essential to mitigate its effects at all levels. Future damages must be avoided by careful management.
How will climate change impact the world's oceans?
What is the effect of climate change upon the world's oceans?
Since its inception, climate change has had a significant impact on the oceans and marine life of the world. The depletion of the ozone layer, which causes constant oceanic warming, has caused major disruptions to marine ecosystems. This has led to coral bleaching and a decline in species.
Climate change may also be responsible for extreme sea level rises and more unpredictable weather conditions, which can prove to be fatal to coastal areas. Additionally, temperature changes may cause water systems to lose oxygen. This can result in "dead areas" in which abundant marine life is reduced.
Ocean acidification is also being caused by excessive carbon dioxide in the atmosphere. Ocean acidification causes an increase in pH which affects the vital functions of animals such as crabs, clams, and oysters that cannot adapt to changing conditions.
Higher temperatures can also alter natural habitats by changing their geographic locations or shrinking them together, thus becoming uninhabitable for certain species that depend on them. This increase in ocean stress accelerates already high extinction rates amongst many species worldwide causing a severe imbalance between predators and prey that might eventually lead to complete extinctions.
The impacts of climate change have rippled through entire ecosystems. They impact multiple species either directly or indirectly through evaporation, decreasing water volumes, or sharp temperature changes. This could jeopardize any sustainable development for fishing and other maritime activities. Overall climate change continues one by one wiping out entire species from our planet transforming future lives on land but most importantly deep below the surface of our oceans.
