In a surprising move, the National Institutes of Health has announced it will no longer fund research on the health effects of climate change, as revealed by internal records obtained by ProPublica. This decision may have significant implications for our understanding of the intersection of environmental health and climate change. As the world grapples with rising temperatures and extreme weather events, the need for climate change research and public health studies has never been more pressing. With the NIH pulling out, it remains to be seen who will fill the gap in funding for this critical area of study, including climate change mitigation and environmental health impacts.
