The US health department is preparing to launch an office focused on the climate crisis as a public health issue, something it outlined in a January executive order.

The Wall Street Journal, citing anonymous sources, said resources for the new Office of Climate Change and Health Equity are being assembled now. The WSJ reports:

The new office is likely to spur initiatives touching on many aspects of healthcare, according to people briefed on the planning and White House releases. It is expected to offer protections for populations most at risk—including the elderly, minorities, rural communities and children—and could eventually lead to policies compelling hospitals and other care facilities to reduce carbon emissions, the people said.
