Rapid ice melt could permanently alter the Arctic ecosystem and trigger catastrophic events as far as the Indian Ocean if greenhouse gas emissions are left unchecked, according to a Stockholm Environment Institute Arctic Resilience Report.

The five-year study identified 19 climate tipping points—which irreversibly alter ecosystems due to sudden or overwhelming change—that "can and have occurred" in the Arctic, including increased vegetation on the tundra that could cause more heat absorption, the collapse of important fisheries and higher methane release. "Human-driven climate change greatly increases the risk of Arctic regime shifts, so reducing global greenhouse gas emissions is crucial to reducing this risk," the report says.
In mid-November, temperatures in the Arctic region reached 36 F (20 C) above normal.

Most of us have heard about UN researchers warning that we need to make dramatic changes in the next 12 years to limit our risk of extreme heat, drought, floods and poverty caused by climate change. Report after report about a bleak climate future can leave people in despair.
Losing weight, improving heart health and decreasing your chances for metabolic diseases like diabetes may be as simple as cutting back on a handful of Oreos or saying no to a side of fries, according to a new study published in the journal The Lancet Diabetes & Endocrinology.
It's important to remember that one person can make a difference. From teenagers to world-renowned scientists, individuals are inspiring positive shifts around the world. Maybe you won't become a hard-core activist, but this list of people below can inspire simple ways to kickstart better habits. Here are seven people advocating for a better planet.
Scotland produced enough power from wind turbines in the first half of 2019, that it could power Scotland twice over. Put another way, it's enough energy to power all of Scotland and most of Northern England, according to the BBC — an impressive step for the United Kingdom, which pledged to be carbon neutral in 30 years.

It's been a particularly terrible summer for bees. Recently, the U.S. Environmental Protection Agency (EPA) announced it is allowing the bee-killing pesticide sulfoxaflor back on the market. And just a few weeks prior, the USDA announced it is suspending data collection for its annual honeybee survey, which tracks honeybee populations across the U.S., providing critical information to farmers and scientists.
