19 Climate Tipping Points Occurring in the Arctic​

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.

Agriculture is on the front lines of climate change. Whether it's the a seven-year drought drying up fields in California, the devastating Midwest flooding in 2019, or hurricane after hurricane hitting the Eastern Shore, agriculture and rural communities are already feeling the effects of a changing climate. Scientists expect climate change to make these extreme weather events both more frequent and more intense in coming years.

In Long Beach, California, some electric buses can charge along their route without cords or wires.

When a bus reaches the Pine Avenue station, it parks over a special charging pad. While passengers get on and off, the charger transfers energy to a receiver on the bottom of the bus.
