Cholera cases in East Africa increase by roughly 50,000 during El Niño, the cyclical weather occurrence that profoundly changes global weather patterns, new Johns Hopkins Bloomberg School of Public Health research suggests.

The findings, researchers say, could help health ministries anticipate future cholera surges during El Niño years and save lives.

NASA's Aqua satellite observed how strong wind shear was literally pushing Tropical Cyclone Cook apart as it displaced the bulk of clouds to the southeast of the center.    

NASA's Aqua satellite passed over Cook on April 11 at 0305 UTC (11:05 p.m. EST) and captured a visible and infrared image of the storm. The Moderate Resolution Imaging Spectroradiometer or MODIS instrument took a visible image of the storm. The image showed that strong vertical wind shear had pushed the bulk of clouds and thunderstorms southeast of the center of circulation.

With spring finally here and warmer temperatures just around the corner, snow will slowly melt away, releasing us from the clutches of winter. However, that’s not the only thing that the melting snow will release. Researchers from McGill University and École de technologie supérieure in Montreal have found that urban snow accumulates a toxic cocktail from car emissions - pollutants that are in turn unleashed into the environment as the weather warms up.

Global warming will thaw about 20% more permafrost than previously thought, scientists have warned; potentially releasing significant amounts of greenhouse gases into the Earth’s atmosphere.

A new international research study, including climate change experts from the University of Leeds, University of Exeter and the Met Office, reveals that permafrost is more sensitive to the effects of global warming than previously thought.

In the wake of 2015 Climate Paris Agreements to limit global temperature below 2°C above pre-industrial levels, many governmental and private stakeholders have advocated for the introduction of policies to mitigate climate change. This would affect directly only the fossil-fuel and utility sector, but it would also expose indirectly many other economic sectors, in particular the energy-intensive sectors. The financial system can be affected due to its exposure to firms in the form of equity shares, bonds holdings and loans. However, the impact of climate policies on the financial system has remained unclear so far.

New research on solar storms finds that they not only can cause regions of excessive electrical charge in the upper atmosphere above Earth's poles, they also can do the exact opposite: cause regions that are nearly depleted of electrically charged particles. The finding adds to our knowledge of how solar storms affect Earth and could possibly lead to improved radio communication and navigation systems for the Arctic.
