East African Floods and Droughts Caused by El Nino

East Africa suffers regularly at the hands of faraway climatic events such as the warm El Niño or the cool La Niña phases of the El Niño-Southern Oscillation (ENSO). Now, scientists know that the waxing and waning of floods and droughts in the region at the hands of ENSO has been a regular feature dating back 20,000 years.

Tracking the Japanese Tsunami Debris

Most people will have seen the images depicting the devastating impact of the 9.0 Tohoku Earthquake which destroyed coastal towns along the Japanese east coast near Sendai. Entire villages and communities are gone, along with the lives that inhabited them.

Of less, but still important, concern than the lives lost, is what will happen to all the debris which was washed out to sea as a result of the tsunami.

Projections of just what will happen to the debris have been made by Nikolai Maximenko and Jan Hafner at the University of Hawaiʻi at Mānoa’s International Pacific Research Center, shown in the animated image below

Wind and Solar Could Reliably Supply 25 Percent of Oahu Electricity Demand

“The findings of this study show it is feasible to integrate large-scale wind and solar projects on Oʻahu but also have value beyond Hawaiʻi. Both large mainland utilities and relatively small and/or isolated grids that wish to integrate significant amounts of renewable energy while maintaining reliability for their customers can learn from this study,” said Hawaiʻi Natural Energy Institute (HNEI) director Dr. Rick Rocheleau, regarding a study which shows that 500 MW of wind energy and 100 MW of solar power could supply more than 25% of O’ahu’s projected electricity demand.
