An international team of researchers has used a new modeling technique to estimate that by the year 2100, the world’s cities could warm by as much as 4.4 degrees Celsius on average.
Trillions upon trillions of microbes have remained locked away in the Arctic’s permafrost in a “deep sleep” for thousands of years. But the Arctic is warming twice as fast as the rest of the world in the wake of climate change.
The threshold for dangerous global warming will likely be crossed between 2027 and 2042 - a much narrower window than the Intergovernmental Panel on Climate Change's estimate of between now and 2052.
With low oxygen concentrations increasing in lakes and reservoirs across the world, these ecosystems will produce higher concentrations of methane in the future, leading to more global warming.
The human-caused climate change made the ‘Day Zero’ drought in southwestern South Africa — named after the day when Cape Town’s municipal water supply would need to be shut off — five to six times more likely.
For the first time since records began, the main nursery of Arctic sea ice in Siberia has yet to start freezing in late October. The delayed annual freeze has been caused by extreme warmth.
After 13 months of collecting data, history’s largest Arctic research expedition returned with grim news. “We witnessed how the Arctic Ocean is dying,” the mission leader said.
Since the mid-1990s, coral in the Great Barrier Reef has declined by more than 50%. The research spanned the entire 2,300 km of the Great Barrier Reef and found a disturbing loss at pretty much every level.
