The Eco News Roundup brings stories and commentary about issues related to climate change, renewable energy and the environment.

The Year Climate Change Began to Spin Out of Control

For decades, scientists have warned that climate change would make extreme events like droughts, floods, hurricanes, and wildfires more frequent, more devastating, or both. In 2017, we got an up-close look at the raw ferocity of such an altered world as high-category hurricanes battered the East and Gulf coasts, and wind-whipped fires scorched the West (see “Did Climate Change Fuel California’s Devastating Fires? Probably”).

We’re also seeing with greater clarity how these dangers are interlinked, building upon one another toward perilous climate tipping points. And yet for all the growing risks, and the decades we’ve had to confront them, we have yet to address the problem in a meaningful way (see “Trump’s Five Biggest Energy Blunders in 2017”)

We’re witnessing the fastest decline in Arctic sea ice in at least 1,500 years

The Arctic Ocean once froze reliably every year. Those days, it seems, are over.
On Tuesday, NOAA released its latest annual Arctic Report Card, which analyzes the state of the frozen ocean at the top of our world. Overall, it’s not good.

“The Arctic is going through the most unprecedented transition in human history,” Jeremy Mathis, director of NOAA’s Arctic research program, said at a press conference. “This year’s observations confirm that the Arctic shows no signs of returning to the reliably frozen state it was in just a decade ago.”

Without fanfare, oil companies just received a tax break on New Year’s Day

Congressional Republicans allowed a tax on oil companies that generated hundreds of millions of dollars annually for federal oil-spill response efforts to expire this week — a move that amounts to another corporate break in the wake of lawmakers’ sweeping tax overhaul late last month.

The tax on companies selling oil in the United States generated an average of $500 million in federal revenue per year, according to the Government Accountability Office. The money, collected through a 9 cents-per-barrel tax on domestic crude oil and imported crude oil and petroleum products, constituted the main source of revenue for the Oil Spill Liability Trust Fund.

Oceans suffocating as huge dead zones quadruple since 1950, scientists warn

Ocean dead zones with zero oxygen have quadrupled in size since 1950, scientists have warned, while the number of very low oxygen sites near coasts have multiplied tenfold. Most sea creatures cannot survive in these zones and current trends would lead to mass extinction in the long run, risking dire consequences for the hundreds of millions of people who depend on the sea.

Climate change caused by fossil fuel burning is the cause of the large-scale deoxygenation, as warmer waters hold less oxygen. The coastal dead zones result from fertiliser and sewage running off the land and into the seas.

Biodiversity redistribution under climate change: Impacts on ecosystems and human well-being

Climate change is causing geographical redistribution of plant and animal species globally. These distributional shifts are leading to new ecosystems and ecological communities, changes that will affect human society. Pecl et al. review these current and future impacts and assess their implications for sustainable development goals.

Scientists Warn of Permanent Drought for 25% of Earth By 2050 If Paris Goals Not Reached

In a new study that adds to the lengthy and ever-growing list of potential consequences of global climate inaction, scientists warn that around a quarter of the Earth could end up in a permanent state of drought if the planet warms by two degrees Celsius by 2050.

“Our research predicts that aridification would emerge over about 20-30 percent of the world’s land surface by the time the global mean temperature change reaches 2ºC,” said Manoj Joshi, one of lead researchers of the study, which was published on Monday in the journal, Nature.

At BPI Campus our Progressive Agenda is:
1. People matter more than profits.
2. The earth is our home, not our trash can.
3. We need good government for both #1 and #2.
