What has changed – and what is not – from finding threatening EPA -e

2003, several countries and environmental groups sued US EPA for violating Pure air law not regulating emissions from new vehicles.

When file eventually reached the Supreme Court, a group of climatic scientists contributed to the short Amicus– A legal document in which a third party that is not directly involved in the case may offer testimony – praise data showing that increasing global temperatures are directly caused by human activity. This has led to The Supreme Court decides that greenhouse gases Did the pollutants represent according to the Clean Air Act and, ultimately, on EPA -in 2009. finding threat that greenhouse gas emissions endanger human health. The finding of vulnerability has become the basis for the government regulation of greenhouse gases. Sixteen years later, Trump’s administration is ready to be abolishedtogether with Other environmental protection.

In Novi comment published in AGU progressesScott Saleska and colleagues, authors of a short amicus, think about short and harm the findings of threatening Potential abolition could cause.

Today, many worries of climatic scientists with the early 2000s have become reality, the authors say. Earth’s 12 warmest years on the record all happened after 2009. Oceani grow hot and sourand the Arctic marine ice is withdrawal. Increase in sea level It accelerates – from 2.1 millimeters a year between 1993 and 2003 to 4.3 millimeters a year between 2013 and 2023. The continuation of warming also affects human health. Direct Death associated with warmth are on the rise, and they are also firesrainfall of extremes like flood and droughtenabled by air conditioning Disease spreadand disorders in agricultural productivity.

Amicus short authors also notice that attribution The science, a field that connects certain weather events with climate change, has progressed since 2009. Today, they are even firmer in their attitude that climate change is a serious threat to society.

Threatening findings are likely to require a long legal procedure and convincing proof that climate change does not pose a risk for the health and well -being of people. But the ability to abolish implies a worrying lack of confidence in science and increasing politicization over climate issue, the authors say. If the role of climate science in creating policies is weakened, it will harm scientific progress and our national well -being, they warn.
