 Bet365 lotto review Recent,According to the official website of MIT,MIT Global Change Science and Policy Joint Project Team is based on population and economic growth、Technical change、"Paris Agreement" emission reduction commitment and national independent contribution (NDC)、Comprehensive analysis of geopolitical situations and other factors,Release "Global Changes in 2023"。This report shows a policy that has a global warming policy and restricting global warming at 1.5 degrees Celsius,Energy for the Earth、Grain、The latest prediction of water and climate system,and the realization of the climate goals of the Paris Agreement。

On the one hand,Many countries and regions have made progress in fulfilling the promise of the Paris Agreement,Formulated a more ambitious greenhouse gas emission reduction target。On the other hand,The funds required for the most developed countries to achieve sustainable development have not been implemented。In the global inventory comprehensive report of 2023,The Convention on the United Nations Climate Change Framework evaluates the emission reduction of the parties to each party in the Paris Agreement,Global greenhouse gas emissions have not been controlled in the Paris Agreement,control the temperature increase below 2 degrees Celsius,It is best to standard below 1.5 degrees Celsius。bet365 Play online games "Global Changes in 2023" discovery,Although these two global temperature targets can still be achieved,But the need for countries to increase emission reduction。

Although the El Nino phenomenon is the short -term influencing factor of high -temperature record high -temperature in 2023,But the impact of human factors is more long -lasting。With the global temperature warming close to 1.5 degrees Celsius- The ideal upper limit of the Paris Agreement,The emergence of extreme weather such as floods will be earlier than expected、More frequent,The current greenhouse gas emission reduction policy cannot prevent the earth from exceeding this threshold。

bet365 Play online games "Global Changes in 2023" analyzed the two scenarios,The first is "Current Trend",Assume that the national independent contribution target that signed the Bet365 lotto review Paris Agreement was achieved before 2030 and maintained it after it; the second was "Accelerating Action",that is to the end of this century,Global warming caused by human activities at least 50%of the possibility is limited and stabilized within 1.5 degrees Celsius。

Forecast according to the current trend,From 2020 to 2050,The share of fossil fuels in the global energy structure will drop from 80%to 70%,Renewable energy such as wind energy and solar energy is the fastest growing energy,increased more than 8.6 times。Forecast according to the accelerated action scenario,The share of low -carbon energy will increase from 20%to slightly higher than 60%,Wind and solar usage will increase by more than 13.3 times。

Under the current trend, calculate,until 2060,Global climate warming bet365 live casino games may exceed 2 degrees Celsius at a probability of more than 50%,By 2100 more than 2.8 degrees Celsius,By 2150 more than 3.8 degrees Celsius。From the perspective of climate model,North America and South America、Europe、northern Asia and Southeast Asia、Southern Africa and Australia Latary,The highest temperature may exceed the average change trend,With human factors, the climate warming intensifies,These areas are expected to experience a more obvious record high temperature event。Calculated under the acceleration action,Global temperature will continue to rise in the next 20 years,But by 2050,Global temperature will tend to stabilize,Then there is a slight decrease in the second half of this century。
