The news doesn’t come as a surprise to scientists and others who’ve been watching, but marks a milestone nonetheless: 2016 was the warmest year on record, dating back to the start of modern record keeping in 1880. And it’s the third record year in a row, keeping up a long-term trend of warming.

Three interesting pieces of news about climate change, in case you missed them:
For starters, 2015 is shaping up to be the warmest year on record since 1880, according to new data from the National Oceanic and Atmospheric Administration.

Second, if you’re wondering about the longer-term impacts of climate change: Climate Central has produced a startling new, interactive graphic that shows the potential effects of sea level rise, should the world continue to grow warmer, melting more and more of the world’s ice sheets and glaciers. From a general view of the impacts on the United States, you can drill down into the graphic and see what’s likely to happen in your nearest coastal community. You can adjust the scene to see what might happen under various scenarios, should we actually succeed in cutting back carbon emissions.

From warmer temperatures to natural disasters such as flooding and drought, changing patterns of climate are having billion-dollar impacts on our food-growing systems. But scientists are struggling to find ways to measure and predict what may happen in the future—and to translate that into policies to help feed a bulging world population.
“Agricultural risks are growing, including climate change,” said Cynthia Rosenzweig of the NASA Goddard Institute for Space Studies, an Earth Institute affiliate. “At the same time, a consistent approach is needed to enable the agricultural sector to analyze these issues.”
She spoke Friday at a panel on food security at the annual meeting of the American Association for the Advancement of Science in Boston. Also on the panel were Thomas R. Karl of the National Oceanic And Atmospheric Administration’s National Climatic Data Center, Paul R. Ehrlich of Stanford University, and Felix Kogan of NOAA.
Cynthia Rosenzweig of the Goddard Institute for Space Studies and Paul R. Ehrlich from Stanford University answer questions at a panel on climate and food security held at the 2013 annual meeting of the American Association for the Advancement of Science.
Rosenzweig detailed a new effort to mesh climate science, agricultural expertise and economics to help make better forecasts, titled the Agricultural Model Intercomparison and Improvement Project—“AgMIP.” The multi-disciplinary effort involves scientists, economists and food experts on five continents.
“What’s been done over past decades is a whole cornucopia,” she said. “It’s hard to compare studies, and it’s hard to understand what all the studies are actually projecting. We need a consistent approach, and we need to set it up long-term.”
