The long and severe drought in the U.S. Southwest pales in comparison with what’s coming: a “megadrought” that will grip that region and the central Plains later this century and probably stay there for decades, a new study says.

Thirty-five years from now, if the current pace of climate change continues unabated, those areas of the country will experience a weather shift that will linger for as long as three decades, according to the study, released Thursday.

Researchers from NASA and Cornell and Columbia universities warned of major water shortages and conditions that dry out vegetation, which can lead to monster wildfires in southern Arizona and parts of California.

UNITED NATIONS -- The goal set by the presidents of Liberia, Sierra Leone and Guinea of reducing the number of new cases of the deadly disease to zero by April 15 can be reached — but only if local communities stop unsafe burials and healing practices that involve human contact, the U.N. Ebola chief said Wednesday.

Dr. David Nabarro told the U.N. General Assembly that there are now 10 times fewer people diagnosed with Ebola each week than there were last September. But he said preventing the final 10 percent of infections — about 120 to 130 new cases per week — is probably going to be the hardest because it's like looking for a needle in a haystack.

Ismael Ould Cheikh Ahmed, who heads the the U.N. Ebola mission in West Africa SAID ...."denial, distrust and a lack of understanding (of Ebola) continue to create resistance in certain pockets and lead to dangerous practices that probably promote further outbreaks."

Ebola virus disease (EVD) is a complex zoonosis that is highly virulent in humans. The largest recorded outbreak of EVD is ongoing in West Africa, outside of its previously reported and predicted niche. We assembled location data on all recorded zoonotic transmission to humans and Ebola virus infection in bats and primates (1976–2014). Using species distribution models, these occurrence data were paired with environmental covariates to predict a zoonotic transmission niche covering 22 countries across Central and West Africa. Vegetation, elevation, temperature, evapotranspiration, and suspected reservoir bat distributions define this relationship. At-risk areas are inhabited by 22 million people; however, the rarity of human outbreaks emphasises the very low probability of transmission to humans. Increasing population sizes and international connectivity by air since the first detection of EVD in 1976 suggest that the dynamics of human-to-human secondary transmission in contemporary outbreaks will be very different to those of the past.
