- warns David Wolfe, a Cornell expert on the effects of climate change on agriculture. His gloomy assessment was part of a report by the Northeast Climate Impacts Assessment (NECIA) Synthesis Team, presented July 11 at a press conference at the New York Botanical Garden. Choices made today could have profound impacts on tomorrow's agriculture and natural landscapes, he said. In simultaneous press conferences in seven northeastern cities, the team of independent experts, in collaboration with the Union of Concerned Scientists, presented analyses of the impact of climate change on key sectors in the northeastern United States. By providing the best available science on the issue, they hope to persuade opinion leaders, policy-makers and the public to make informed choices about climate-change mitigation and adaptation.
