Rating agencies’ evaluation of an economy’s credit willingness and ability to fulfill its debt repayment obligations，is a key indicator for international investors to refer to。Recently，An economics research team led by the University of Cambridge in the UK used artificial intelligence models to simulate the impact of climate change on sovereign credit bet365 free bets，And issued relevant reports。Report Display，Unless action is taken to reduce carbon emissions，Otherwise the sovereign credit bet365 free bets of many economies are likely to decline over the next 10 years。

　bet365 free bets poses a huge threat to wealth

The research object is the future sovereign credit rating of 108 countries，Forecast results cover the next 10 years、30 years、50 years and the end of the 21st century。Research shows，In compliance with the Paris Agreement，If the global temperature rise can be controlled within 2℃，Economies’ sovereign credit bet365 free bets will not suffer short-term impacts from climate change，The long-term impact of global warming will therefore be controlled to a minimum。If no measures are taken to curb greenhouse gas emissions，Then 2030，63 countries will have their bet365 free bets dropped by at least 1 notch on average。If significant emissions reductions are not made，By the end of the 21st century，80 countries will have their bet365 free bets dropped by an average of 2.48 levels，India and Canada’s bet365 free bets will drop by 5 notches。

A credit rating downgrade caused by bet365 free bets alone will result in additional interest payments on sovereign debt，And this is only a small part of the economic consequences of not limiting carbon emissions in the next 80 years。By 2100，This may cause global losses of US7 billion to US5 billion every year。

This artificial intelligence model for predicting the sovereign credit bet365 free bets of various countries is generated based on the bet365 free bets of a large international rating company from 2015 to 2020。The researchers combined these data with climate economic models and assessments of natural disaster risks，Received “climate smart” credit bet365 free bets for a range of global warming scenarios。Researchers call their predictions "extremely conservative"，Because these data only track increases in temperature。When their models incorporate climate change over time，That is when we are witnessing various extreme weather events，The phenomenon of credit rating decline and related cost increase becomes more serious。

Study Participant、Kamiar Mohaddes, a researcher at Cambridge University School of Management said，If the current trajectory of carbon emissions continues，Most countries in the sample will see their sovereign credit bet365 free bets decline by 2030，Nearly all countries’ sovereign credit bet365 free bets will decline by 2100。Although complying with the Paris Agreement is difficult，But predictions indicate，Strong climate policies will significantly reduce the impact on bet365 free bets。

　　Rating agencies need to pay more attention to bet365 free bets

Researchers said，Current green finance indicators，such as "environment、Social and Governance” (ESG) bet365 free bets，The phenomenon of disconnection between existence and science。

Study Participant、Matthew Agarwala, a researcher at the Bennett Institute of Public Policy at the University of Cambridge said，ESG bet365 free bets market expected to exceed billion this year，But it desperately lacks a basis in climate science。As climate change threatens the national economy more and more，It will become more difficult for countries to shoulder debt，The cost will also be higher。

Agarwala said，By linking bet365 free bets science to indicators already embedded in financial systems，bet365 free bets risks can be assessed without compromising scientific credibility and economic validity。

　In the long run，Climate change may bring huge challenges to the global economy and the sovereign credit bet365 free bets of various economies。This prediction is not unfounded。In comparison，January 2020 to present，The economic turmoil caused by the new coronavirus pandemic has caused the bet365 free bets of 48 sovereign countries to be downgraded by the three major rating agencies。Agarwala talks about，The fiscal consequences of the epidemic have panicked finance ministers in many countries，They should seize this opportunity now，Invest in decarbonization and environmental restoration projects that stimulate economic growth，To prevent climate change from further impacting public finances。

　　The importance of long-term evaluation is becoming increasingly important

This study shows，Even if the goals set by the Paris Agreement are achieved as scheduled，Global sovereign debt will still be affected by long-term climate change。By 2100，Global sovereign credit bet365 free bets may drop by an average of 0.65 levels，Annual interest payments on sovereign debt will increase by up to billion。

The research team also calculated the possible knock-on effects of a sovereign credit rating downgrade on corporate bet365 free bets and debt in 28 countries。They found out，Under the framework of the Paris Agreement，By 2100，Additional costs to global businesses will reach billion per year，If action is not taken to reduce carbon emissions，This amount will be as high as 62 billion US dollars。

Study Participant、Former S&P Chief Sovereign bet365 free bets Officer Moritz Kraemer said，Rating agencies rarely forecast sovereign debt beyond 3 years。Investors are holding government bonds with longer and longer maturities。Short-term assessments by rating agencies do not provide investors with a reliable measure of credit risk exposure，And this risk exposure may extend into the next 100 years。

Kramer said，We need to establish a credit rating system with an ultra-long-term perspective，And the latest bet365 free bets science is critical to achieving this goal。The research team stated，They follow "First Principles"，As close as possible to bet365 free bets science and real-world financial practice。

Matt Burke, Research Fellow at the Bennett Institute of Public Policy at the University of Cambridge said，Artificial intelligence has the potential to revolutionize how we assess bet365 free bets risk and the environment、Social governance rating method，But we must ensure that the evidence base is self-consistent。

Based on this study，Developing countries with lower credit bet365 free bets are expected to actually be more severely affected by climate change，Countries with higher scores may face more severe credit rating downgrades，This is also in line with the nature of sovereign bet365 free bets。
