Climate Crisis

A new genomic study has homed in on exactly when and where modern penguins originated, suggesting the birds first appeared in Australian and New Zealand waters about 22 million years ago before later spreading south into the cooler Antarctic waters.

New analysis of almost 40 years of satellite data has revealed that the Greenland ice sheet is now shedding so much mass that, even were climate change to halt tomorrow, it is now passed the point of no return and would continue to shrink for some time.

A study claims that in the next 80 years, the global land area exposed to coastal flooding as a result of climate change is set to increase by roughly 50 percent. The rise could threaten tens of millions of people, and up to 20 percent of global GPD.

Researchers have delved into what the coronavirus lockdowns have meant for human-caused Earth vibrations, leading to the discovery of what say is the "longest and most pronounced quiet period of seismic noise in recorded history.

The dramatic changes taking place in the Arctic as a result of climate change have long been known to spell trouble for polar bears, but a new study mapping out their future has provided a particularly grim outlook.

New analysis has revealed that emissions of methane, a particularly potent greenhouse gas, have now hit record highs, with the surge being driven in large part by increases in the burning of fossil fuels and increasing agricultural activity.

A new adaptation of a pre-stressing technique has been used to produce concrete that is lighter but with comparable strength, an advance that if widely applied, could save significant amounts of CO2.

Scientists at Stanford have observed a dramatic increase in the concentration of phytoplankton in the Arctic Ocean, a phenomenon they liken to a “thickening algae soup” that will cause a big change in how effectively it absorbs carbon dioxide.

A new study out of the University of Sheffield makes a case for a geoengineering technique known as enhanced rock weathering, which essentially involves supercharging soil’s ability to remove CO2 from the atmosphere by sprinkling it with rock dust.

What would Earth’s climate naturally be doing if it weren’t for human intervention? Researchers have now analyzed 12,000 years of climate data, and found that human-induced warming interrupted and reversed a long-term natural global cooling period.

Scientists have uncovered an accelerated heating trend taking place at the South Pole, with 30 years of weather data revealing the region has warmed at more than three times the global rate since 1989.

New observations from a weather station in Siberia illustrate the warming trend taking hold in the Arctic Circle, with scientists logging an extreme temperature of 38 °C (100.4 °F), thought to be a new record for the region.
