Fiber optic cable monitors microseismicity in Antarctica
Researchers shared how they are using fiber optic cable to detect the small earthquakes that occur in ice in Antarctica.

When the fiber is disturbed by earthquakes or icequakes, there are changes in the size, frequency and phase of laser light scattered back to the DAS receiver that can be used characterize the seismic event.

California Governor Moves To Ban Fracking By 2024
California Gov. Gavin Newsom announced plans to ban hydraulic fracturing by 2024 as part of a longer-term aim to end all oil extraction in the state.

The governor has ordered the state's top oil regulator to implement regulation to stop issuing new fracking permits by 2024. He has also directed the state's air resources agency to look at ways to phase out oil extraction completely by 2045.

"The climate crisis is real, and we continue to see the signs every day," Newsom said in a Friday press release. "As we move to swiftly decarbonize our transportation sector and create a healthier future for our children, I've made it clear I don't see a role for fracking in that future and, similarly, believe that California needs to move beyond oil."

The plan aligns with the state's broader goal to reach net-zero carbon dioxide emissions by 2045.

... California would be the largest oil-producing state to ban fracking. Environmentalist groups — who argue that fracking drains water levels, harms public health and contributes to global warming — say the 2024 and 2045 deadlines are too late.

"While precedent setting, both timelines are not aggressive enough," California's Sierra Club said in a statement. "They fail to meet the urgency of the climate crisis we face and protect frontline communities facing the brunt of fossil fuel pollution that still need immediate health and safety protections."

Climate Change is the defining issue of our time and we are at a defining moment. From shifting weather patterns that threaten food production, to rising sea levels that increase the risk of catastrophic flooding, the impacts of climate change are global in scope and unprecedented in scale. Without drastic action today, adapting to these impacts in the future will be more difficult and costly.
