The UN Climate Panel report on the science of climate change released on Monday outlines five possible scenarios for the future. The report claims to be a serious problem and said it all depends on how quickly humans stop greenhouse gas emissions. To tackle the problem, it was told that socioeconomic changes in areas such as population, urban density, education, land use and wealth also have to be controlled.
For example, increase in population means increase in demand for fossil fuels and water. Education technology can affect the rate of development. Emissions increase when land is converted from forest to agricultural land. Said each scenario is combined to identify both the emissions level and the shared socioeconomic pathway, or SSP, used in the respective mathematics.
A UN climate science report said on Monday that extreme heat waves, which previously occurred only once every 50 years, are now occurring once every decade due to global warming, while rains have started increasing. And the drought is getting worse.
The report published by the United Nations-appointed Intergovernmental Panel on Climate Change has five important points, which you should read…
The report said that almost all warming since the pre-industrial period was caused by the release of heat-trapping gases such as carbon dioxide and methane. Much of this is the result of humans burning fossil fuels – coal, oil, wood and natural gas. Scientists say that only part of the temperature increase recorded since the 19th century may have come from natural pressure.
Almost all countries have signed the 2015 Paris Climate Agreement which aims to keep global warming below 2 °C (3.6 °F)….and ideally 1.5 by the end of the century compared to pre-industrial times. It is emphasized not to exceed °C (2.7 F). (by the year 2100, compared to the 19th century)
More than 200 authors of the report looked at five scenarios and concluded that all could see the world crossing the 1.5-degree threshold by the 2030s. (Earlier than previous predictions) Temperatures in three of these scenarios 2°C above the pre-industrial average.
The more than 3,000-page report concludes that ice is melting and sea levels are rising. Severe weather events—from hurricanes to heat waves—are all increasing and becoming more dangerous. Scientists are clearly saying over and over again that the 1.5 °C target is probably out of reach now because more than 1 °C of heat has already occurred and a further rise in temperature is ‘locked’ due to emissions already in the atmosphere. It becomes
While many of the report’s predictions paint a grim picture of the impact of humans on the planet and the consequences that lie ahead, the IPCC also found tipping points, such as catastrophic ice sheet collapses and a sudden slowing of ocean currents. Occurrences are ‘less likely’, although hope can be raised by working on them.
The panel is made up of independent experts put forward by governments and organizations to provide a high potential scientific consensus on climate change. Scores of scientists provide regular reports on many aspects of global warming, which governments discuss about what countries can contribute to curbing greenhouse gas emissions and adapting to the effects of climate change.
