THE LIGHTBULB People listen as President Trump speaks at the Conservative Political Action Conference (CPAC) at National Harbor, Md. in February. (Reuters/Joshua Roberts) Democrats and Republicans are deeply divided on not just what to do about human-caused climate change — and whether it even exists. But there exists a lesser-known yet probably more important cleavage when it comes to defining the climate positions of future elected GOP officials. It is the gap between older and younger GOP voters. According to a new survey released by the Pew Research Center on Monday, millennial GOP voters — those born between 1981 and 1996 — disagree with their older partisan counterparts across a range of energy and environmental issues. Younger Republicans disagree with their older partisan counterparts on the extent to which climate change is already affecting the world. This new … [Read more...] about The Energy 202: Older and younger GOP voters don’t agree on climate change

(The Conversation is an independent and nonprofit source of news, analysis and commentary from academic experts.) Mark Serreze, University of Colorado (THE CONVERSATION) Scientists have known for a long time that as climate change started to heat up the Earth, its effects would be most pronounced in the Arctic. This has many reasons, but climate feedbacks are key. As the Arctic warms, snow and ice melt, and the surface absorbs more of the sun’s energy instead of reflecting it back into space. This makes it even warmer, which causes more melting, and so on. This expectation has become a reality that I describe in my new book “Brave New Arctic.” It’s a visually compelling story: The effects of warming are evident in shrinking ice caps and glaciers and in Alaskan roads buckling as permafrost beneath them thaws. But for many people the Arctic seems like a faraway place, and stories of what is happening there seem irrelevant to their lives. It can also be hard to … [Read more...] about Melting Arctic sends a message: Climate change is here in a big way
Chris Mooney, The Washington Post Published 9:55 am, Monday, April 23, 2018 Two years ago, former NASA climate scientist James Hansen and a number of colleagues laid out a dire scenario in which gigantic pulses of fresh water from melting glaciers could upend the circulation of the oceans, leading to a world of fast-rising seas and even superstorms. Hansen's scenario was based on a computer simulation, not hard data from the real world, and met with skepticism from a number of other climate scientists. But now, a new oceanographic study appears to have confirmed one aspect of this picture - in its early stages, at least. The new research, based on ocean measurements off the coast of East Antarctica, shows that melting Antarctic glaciers are indeed freshening the ocean around them. And this, in turn, is blocking a process in which cold and salty ocean water sinks below the sea surface in winter, forming "the densest water on the Earth," in the words of study lead author … [Read more...] about One of the most worrisome predictions about climate change may be coming true
In recent years, New Yorkers, like people all over the world, have faced the realities of human-made climate change: extreme storms, rising sea levels, summer heat waves, massive winter nor'easters, and a $20 billion plan to reduce future flooding. Last year, the United States as a whole experienced the highest losses from climate disasters, an estimated $309 billion. With the Big Oil lobby firmly entrenched in the Trump administration, national action against climate change has ground to a halt. The path to climate safety is closing fast. Climate change results overwhelmingly from the burning of coal, oil and gas, and the carbon dioxide emissions that result. (Emissions from agricultural production and land use change are also drivers.) The key to climate safety is therefore decarbonization: to shift from the fossil fuels to zero-carbon energy, such as wind, solar, hydro and nuclear power. The future of the planet therefore depends mainly on the few place that produce the … [Read more...] about We can fix this: Don’t be dispirited by Big Oil’s power in the age of Trump. Real climate change solutions are in reach.
The Atlantic Ocean circulation that carries warmth into the Northern Hemisphere's high latitudes is slowing down because of climate change, a team of scientists asserted Wednesday, suggesting one of the most feared consequences is already coming to pass.The Atlantic meridional overturning circulation has declined in strength by 15 percent since the mid-20th century to a "new record low," the scientists conclude in a peer-reviewed study published in the journal Nature. That's a decrease of 3 million cubic meters of water per second, the equivalent of nearly 15 Amazon rivers.The AMOC brings warm water from the equator up toward the Atlantic's northern reaches and cold water back down through the deep ocean. The current is partly why Western Europe enjoys temperate weather, and meteorologists are linking changes in North Atlantic ocean temperatures to recent summer heat waves.The circulation is also critical for fisheries off the U.S. Atlantic coast, a key part of New England's economy … [Read more...] about Studies say Atlantic Ocean’s circulation slowing dramatically, increasing climate change fears
