Pollution Has Slowed Around The World. Scientists Wonder How That Will Affect Maine

April 2, 2020 — Atmospheric and oceanographic scientists are just as concerned as anyone about helping their friends and family, the nation and the world make it through the trials of the COVID-19 pandemic. But it is also their job to pay attention to a kind of grand experiment that’s underway — an unprecedented hiatus in human pressure on global ecosystems and what that hiatus could mean on the ground, and on the water, for Maine.

Paul Mayewski is the director of the University of Maine’s Climate Change Institute. He says that the COVID-19 pandemic has pushed the pause button on pollution worldwide.

“Unfortunately, like 9/11, this is a situation in which there is a tremendous shutdown in activity, even more dramatically than 9/11 because it is happening all over the world,” he says.

For scientists such as Mayewski, it’s a chance to study phenomena that hearken back to the pre-industrial era and, some believe, could provide a snapshot of what a post-fossil future could look like.

Maine fisheries and blueberries could be at stake due to climate change, report says

November 29, 2018 — Climate change has helped Maine’s lobster yield increase fourfold since the 1980s, as warming waters to the south have propelled lobsters north in search of colder waters. But if summer sea temperatures along Maine’s coast continue rising and cross a potentially perilous threshold, lobsters’ survival in a more temperate Gulf of Maine could be in doubt.

The Gulf of Maine has warmed faster than 99 percent of the world’s oceans, and the trend is expected to continue. The warming that has taken place so far, as well as the decline of cod, has proven favorable for Maine’s lobster yields in recent years, but if sea temperatures during the summer rise above 68 degrees Fahrenheit, lobster mortality will increase.

That’s one conclusion from a new report detailing the potential effects of climate change on Maine’s coast. The report, released earlier this month by the Climate Change Institute at the University of Maine, took a close look at how climate change could affect fishing and agriculture. It imagines five climate change scenarios, how they would unfold over the next two decades and the impacts from each one.

The report by Paul Mayewski, the institute’s director, and Maine State Climatologist Sean Birkel predicts an overall trend of warmer, wetter weather with rising sea temperatures, shorter winters, longer summers and more frequent storms.

These predictions are in line with the National Climate Assessment that the Trump administration published the day after Thanksgiving and came a week after Mayewski and Birkel’s report. The national assessment predicts an increase in extreme weather events due to climate change, and major economic losses and heightened health risks as a result.

A global or national climate change assessment might not be applicable to all states or even regions within a state, however, which is why UMaine’s Climate Change Institute has focused on specific regions of Maine, Mayewski said. Mayewski and Birkel used past climate change data collected through Birkel’s Climate Reanalyzer tool to make predictions about coastal Maine’s climate future, and they plan to do the same for other regions in the state.

“Our goal through reports like this is to give people a better idea of how the climate has changed in the past few decades, and understanding what the plausible scenarios are for future climate and how this might impact, in this case, fisheries and blueberries,” Mayewski said.

Maine scientists, academics condemn Trump’s decision on climate accord, see consequences for state

June 2, 2017 — Maine scientists, academics and physicians were dismayed by President Trump’s decision Thursday to withdraw from the Paris climate accord, saying his action will endanger the health of Mainers and harm the state’s fisheries and agriculture.

The move will make the United States look ridiculous in the eyes of world leaders who are trying to effect change, one prominent scientist said.

“China and Europe will become the heroes and we will look like fools,” said Paul Mayewski, director of the Climate Change Institute at the University of Maine.

Mayewski has led more than 55 expeditions to some of the remotest polar and high-altitude locations on Earth, has been published in more than 450 scientific publications, and led climate-change research programs in Antarctica, Greenland and Asia.

Mayewski said that while countries such as China are taking steps to reduce carbon emissions, the U.S., under Trump’s leadership, stands to lose credibility because it remains the second-largest producer of carbon dioxide in the world. He noted that Syria and Nicaragua were the only countries that did not sign the Paris climate agreement.

“We’re giving up, at least politically, the high road on being a leader in climate change,” he said.

Mayewski said Mainers could be harmed by the president’s decision. As temperatures continue to rise and weather patterns become more unstable, extreme heat will make more people vulnerable, especially the sick and the elderly. Climate change also will impact tourism and lobstering, Mayewski said. Health care costs also could increase.
