Fir and spruce trees are expected to die out in the Catskills, and New York City’s backup drinking water supply may well be contaminated as a result of seawater making its way farther up the Hudson River.

These possibilities – modeled deep into this century – are detailed in a new assessment of the impact that climate change will have in New York State. The 600-page report, published on Wednesday, was commissioned by the New York State Energy Research and Development Authority, a public-benefit corporation, and is a result of three years of work by scientists at state academic institutions, including Columbia and Cornell Universities and the City University of New York.

Its authors say it is the most detailed study that looks at how changes brought about by a warming Earth – from rising temperatures to more precipitation and global sea level rise – will affect the economy, the ecology and even the social fabric of the state.

Cynthia Rosenzweig, a senior research scientist at Columbia’s Earth Institute, said the report was much broader […]
