Scientists project a drier Amazon and wetter Indonesia in the future. Climate models predict that an increase in greenhouse gases will dry out the Amazon rainforest in the future while causing wetter conditions in the woodlands of Africa and Indonesia. Researchers have identified an unexpected but major factor in this worldwide precipitation shift: the direct response of the forests themselves to higher levels of carbon dioxide. Source 4o.
Climate change will boost global lake evaporation -- with 'extreme' consequences. Global lake evaporation will increase 16 percent by the end of the century, triggering, among other outcomes, stronger precipitation events, according to a new study. But the specific mechanisms that will drive that phenomenon are not quite what scientists expected. Source 8c.
First mapping of global marine wilderness shows just how little remains. Reporting in Current Biology on July 26 have completed the first systematic analysis of marine wilderness around the world. And what they found is not encouraging; only a small fraction -- about 13 percent -- of the world's ocean can still be classified as wilderness. Source 6m.
Half of the world's annual precipitation falls in just 12 days. Currently, half of the world's measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe. By century's end, climate models project that this lopsided distribution of rain and snow is likely to become even more skewed, with half of annual precipitation falling in 11 days. Source 7o.
Climate change will have dire consequences for US, federal report concludes
A new US government report delivers a dire warning about climate change and its devastating impacts on the health and economy of the country.
The federally mandated study was released by the Trump administration on Friday, at a time when many Americans are on a long holiday weekend, distracted by family and shopping.
Coming from the US Global Change Research Program, a team of 13 federal agencies, the Fourth National Climate Assessment was put together with the help of 1,000 people, including 300 leading scientists. Ref. CNN.
