More than 1,000 scientists and experts have strongly condemned the Biden administration’s move to overturn the 2009 EPA “Endangerment Finding,” a pivotal ruling that authorizes federal regulation of greenhouse gas emissions. Originally established under the Obama administration and upheld by the Supreme Court, the finding recognizes that heat-trapping emissions threaten public health and welfare, serving as the foundation for many environmental regulations. EPA head Lee Zeldin argues the standard is flawed and economically damaging. However, the scientific community warns that reversing this decision undermines climate action efforts and public safety, sparking widespread concern amid ongoing debates about environmental policy and economic impact.
