It was a balmy 67-degree day in New York on March 15, which prompted the inevitable joke that since it’s warm outside, then climate change must be real. The wry comment was made by one of the speakers at the New York Academy of Science’s symposium Science for decision making in a warmer word: 10 years of the NPCC.
The NPCC is the New York City Panel on Climate Change, an independent body of scientists that advises the city on climate risks and resiliency. The symposium coincided with the release of the NPCC’s 2019 report, which found that in the New York City area extreme weather events are becoming more pronounced, high temperatures in summer are rising, and heavy downpours are increasing.
“The report tracks increasing risks for the city and region due to climate change,” says Cynthia Rosenzweig, co-chair of the NPCC and senior research scientist at Columbia University’s Earth Institute. “It continues to lay the science foundation for development of flexible adaptation pathways for changing climate conditions.”
“What you can’t measure, you can’t manage,” said Columbia University’s Klaus Jacob, paraphrasing Peter Drucker and making a concise case for the importance of the work the NPCC is doing.
The changes in temperature and precipitation that New Yorkers are experiencing are broadly tracking the climate change projections made by the NPCC in 2015. However, the 2019 report notes that such comparisons should be viewed with caution because of the role that natural variation plays in the short term.
William Solecki, co-chair of the NPCC said “Recent scientific advances have…helped the panel craft new sets of tools and methods, such as a prototype system for tracking these risks and the effectiveness of corresponding climate strategies.”
One such tool is the Antarctic Rapid Ice Melt Scenario, which the NPCC created to model the effects of melting ice sheets on sea level rise around NYC. The model predicts that under a high-end scenario, monthly tidal flooding will begin to affect many neighborhoods around Jamaica Bay by the 2050s and other coastal areas throughout the city by the 2080s.
The NPCC 2019 report recommends that the city establish a coordinated indicator and monitoring system to enable the city and its communities to better monitor climate change trends, impacts, vulnerability, and adaptation measures.
The report also notes the important role of insurance in support of climate change adaptation and mitigation. “Public–private partnerships are essential for facilitating infrastructure resilience, particularly for publicly owned infrastructure systems that often lack resources for resilience improvements. Coordination of insurance and finance is an important future direction to achieve comprehensive resiliency in infrastructure that reduces negative climate change consequences,” said the report.
