“Are the effects of Global Warming really that bad?”
The short answer to this question is Yes. Even a slight change in the average temperature rise causes a dramatic transformation of our planet (Global Warming). According to the Intergovernmental Panel on Climate Change (IPCC) report, at least Five and a half degrees Fahrenheit will be increased by 2100 which will cause enormous change to every ecosystem and living thing including humans.
Due to the report of IPCC, the above graph shows the projected global average warming. The left panel shows the range of projected median warming across globally modeled pathways within a category, with the category medians. The right panel shows the peak and 2100 emulated temperature outcomes for the categories and for IMPs, and the five illustrative scenarios (SSPxy). The combined range across scenarios and the climate uncertainty for each category are also shown for 2100 warming (thin vertical lines).
Cause
Cause
Most of the reason for global warming is caused by humans. There are various reasons that cause global warming but two facts give the most impact on global warming: the carbon pollution that humans cause by burning fuels and the pollution caused by deforestation. The carbon dioxide, methane, and other pollutants which humans release into the atmosphere trap the heat from the sun, therefore the Earth gets warmer. The below graph is a piece of evidence which shows that the 2010s were hotter than any other decade on record moreover, every decade has been hotter than the previous one from the 1960s which gives alarm to the earth’s climate system: land, atmosphere, oceans, ice, etc.
In the report of IPCC, Panel a shows annual global net anthropogenic GHG emissions by groups of gases from 1990 to 2019 reported in converted based on global warming potentials with a 100-year time horizon. The fraction of global emissions for each gas is shown in 1990, 2000, 2010, 2019; as well as the average annual growth rate between these decades. The single-year peak of emissions in 1997 was due to higher CO2-LULUCF emissions from a forest and peat fire event in South East Asia.
Panel b shows global anthropogenic fluorinated gas emissions individually for the period 1990–2019, normalized relative to 100 in 1990. The different scale for the included fluorinated gas emissions compared to other gases highlights its rapid growth from a low base, but the shaded areas indicate the uncertainty range. Uncertainty ranges as shown here are specific to individual groups of greenhouse gases and cannot be compared. The table shows the central estimate for absolute emissions in 2019, the absolute change in emissions between 1990 and 2019, and emissions in 2019 expressed as a percentage of 1990 emissions.
Effect
Effect
According to the National Oceanic and Atmospheric Administration (NOAA) in 2021, climate disasters that are mainly impacted by global warming have arrived in the United States such as severe storms, floods, drought, and wildfires therefore abundant people have lost their lives. To look for its impact on humans, it threatens the health of people through air pollution, disease, extreme weather situations, forced displacement, pressures on mental health, and increased hunger and poor nutrition in places where people cannot live sufficiently (United Nations). Furthermore, as I mentioned before, it also affects nature such as a rise in sea level, leading to the loss of coastal Islands, a change in precipitation patterns, and increased risks of droughts and floods. Therefore, people have to gain more knowledge about it to stop and prevent global warming for future disasters.
