Arctic, Greenland Stuck in Feedback Loop of Melting

Diminishing Arctic sea ice could make Greenland’s melting even worse, a new study shows. Changing temperatures at the poles driven by global warming have the potential to impact the jet stream, causing it to bend further north than usual.

“Blocking events” caused by the jet stream that exacerbate ice melt have become increasingly common over Greenland since the 1850s. Accelerating Greenland’s melt could not only cause increased sea level rise but a slew of other climate impacts connected to changing ocean temperatures, which in turn would drive more changes.

One scientist said, “It’s a complicated puzzle—but it’s really starting to come together.”

Thousands of Superfund sites exist around the U.S., with toxic substances left open, mismanaged and dumped. Despite the high levels of toxicity at these sites, nearly 21 million people live within a mile of one of them, according to the U.S. Environmental Protection Agency (EPA).

  • If online deliveries continue with fossil-fuel trucks, emissions will increase by a third.
  • So cities in the Netherlands will allow only emission-free delivery vehicles after 2025.
  • The government is giving delivery firms cash help to buy or lease electric vehicles.
  • The bans will save 1 megaton of CO2 every year by 2030.

Cities in the Netherlands want to make their air cleaner by banning fossil fuel delivery vehicles from urban areas from 2025.

As world leaders prepare for this November's United Nations Climate Conference in Scotland, a new report from the Cambridge Sustainability Commission reveals that the world's wealthiest 5% were responsible for well over a third of all global emissions growth between 1990 and 2015.
