In 2021, a group of prominent permafrost researchers like Merritt Turetsky had presented their collective estimate of permafrost emissions, including the abrupt thaw processes, as part of an effort to advocate for a 50% reduction in anthropogenic emissions by 2030 as a necessary milestone to help reach net zero by 2050. Their figures for ...
The San Diego Climate Action Plan was adopted by the City of San Diego in December 2015. It is a local climate action plan whose rules are defined by the Global Warming Solutions Act of 2006 (AB 32), with the goal of reducing greenhouse gas emissions . [ 1 ]
A fire scar is seen outside Fairbanks, Alaska, in August 2022. Wildfire emissions and thawing permafrost have contributed to changes in the Arctic’s tundra, scientists say (NASA/Katie Jepson) ...

Previously known as Golden Gate Zero Emission Marine, ZEI designs and manufactures hydrogen fuel cell power systems and hydrogen refueling solutions with a focus on maritime applications.
Melting permafrost in the Arctic is releasing toxic mercury into the water system, potentially impacting the food chain, scientists say. Arctic permafrost is melting at rapid rates, potentially ...
The Summary. This was the Arctic’s second-hottest year on record, according to a new NOAA report. The tundra has become a source of emissions, rather than a carbon sink, the authors said.

Permafrost temperature profile. Permafrost occupies the middle zone, with the active layer above it, while geothermal activity keeps the lowest layer above freezing. The vertical 0 °C or 32 °F line denotes the average annual temperature that is crucial for the upper and lower limit of the permafrost zone, while the red lines represent seasonal temperature changes and seasonal temperature ...
