100% Renewable Energy Worldwide Isn’t Just Possible—It’s Also More Cost-Effective

Transitioning the world to 100 percent renewable electricity isn’t just some environmentalist pipe dream—it’s “feasible at every hour throughout the year” and is more cost-effective than the current system, which largely relies on fossil fuels and nuclear energy, a new study claims. The research, compiled by Finland’s Lappeenranta University...

It’s not only trees — wildfires imperil water too

The Fourmile Canyon Fire, sparked by a backyard burn west of Boulder, Colorado, in 2010, caused $220 million in damage and destroyed 168 homes. It also scorched nearly a quarter of a watershed that supplies water to the nearby community of Pine Brook Hills. The problems didn’t end there: Long after the blaze was put out, intense rainstorms periodically washed sediment...

Trump breaks with military leaders, removes climate change from list of national security threats

President Donald Trump’s new National Security Strategy removed all mentions of climate change as a national security threat, a decision in line with major steps taken by the administration over the past 11 months to downplay the perils of climate change. Two years ago, the Obama administration issued a strategy that identified climate change as “an urgent and growing...

Arctic Temperatures Are Rising So Fast Computers Don’t Believe They’re Real

320 miles north of the Arctic Circle, a weather station in America’s northernmost city of Utqiaġvik (formerly Barrow), Alaska, has been quietly collecting temperature data since the 1920s. Early this month, while preparing a report on U.S. climate, experts at the National Centers for Environmental Information (NCEI) noticed something odd: They were missing data from...

Climate Change Is Increasing Regional Conflict and Creating Millions of Refugees Across the Globe

Those who are least to blame for climate change are those who are all too often affected first and worst. The world’s least developed countries produce only a fraction of global greenhouse gas emissions and have had far fewer of the benefits reaped by the developed world from their carbon-based economies, yet they are the most vulnerable and the least able to...

Internal watchdog says Dept. of Interior should focus on climate change. It isn’t.

With control of one-fifth of the land area of the United States, the Interior Department is expected to be challenged by more intense wildfires, rising seas and other effects of climate change over the next fiscal year, a new internal government watchdog report has found. Interior’s Office of the Inspector General listed climate change as among the “most significant...

Doomsday on Ice

In a remote region of Antarctica known as Pine Island Bay, 2,500 miles from the tip of South America, two glaciers hold human civilization hostage. Stretching across a frozen plain more than 150 miles long, these glaciers, named Pine Island and Thwaites, have marched steadily for millennia toward the Amundsen Sea, part of the vast Southern Ocean. Further inland, the...

Democrats Are Shockingly Unprepared to Fight Climate Change

There’s a wrinkle in how the United States talks about climate change in 2017, a tension fundamental to the issue’s politics but widely ignored. On one hand, Democrats are the party of climate change. Since the 1990s, as public belief in global warming has become strongly polarized, the Democratic Party has emerged as the advocate of more aggressive climate action. The...

Trump administration releases report finding ‘no convincing alternative explanation’ for climate change

The Trump administration released a dire scientific report November 3, 2017, detailing the growing threats of climate change. The report stands in stark contrast to the administration’s efforts to downplay humans’ role in global warming, withdraw from an international climate accord and reverse Obama-era policies aimed at curbing America’s greenhouse-gas output. The...

The three-degree world: the cities that will be drowned by global warming

When UN climate negotiators meet for summit talks this month, there will be a new figure on the table: 3C. Until now, global efforts such as the Paris climate agreement have tried to limit global warming to 2C above pre-industrial levels. However, with latest projections pointing to an increase of 3.2C by 2100, these goals seem to be slipping out of reach. “[We] still...

The Interior Department Scrubs Climate Change From Its Strategic Plan

In the next five years, millions of acres of America’s public lands and waters, including some national monuments and relatively pristine coastal regions, could be auctioned off for oil and gas development, with little thought for environmental consequences. That’s according to a leaked draft, obtained by The Nation, of the Department of the Interior’s strategic vision:...

Rising Seas Are Flooding Virginia’s Naval Base, and There’s No Plan to Fix It

The one-story brick firehouse at Naval Station Norfolk sits pinched between a tidal inlet and Willoughby Bay. The station houses the first responders to any emergency at the neighboring airfield. Yet when a big storm hits or the tides surge, the land surrounding it floods. Even on a sunny day this spring, with the tide out, the field beside the firehouse was filled with...

Inaction on climate change carries a big price tag, federal report finds

The Trump administration’s reluctance to confront climate change threatens to create a massive burden on taxpayers, as a lack of planning by federal agencies leaves the government ill-equipped to deal with the fallout from rising temperatures, according to independent congressional investigators. The report released yesterday from the Government Accountability Office...
