Big ocean waves whipped up by storms hundreds or even thousands of miles away from Earth’s poles could play a bigger role in breaking up polar sea ice and thus contributing to its melt more than had been thought, a new study suggests.
The study, detailed in the May 29 issue of the journal Nature, found that these waves penetrate further into the fields of sea ice around Antarcticathan current models would suggest, breaking up the ice well away from the edge of the ice. And previous studies have suggested that bigger

Son vientos cargados de humedad por la evaporación del mar, que soplan de forma casi constante en el verano y se chocan con las laderas situadas al NE de las islas, o sea, a barlovento. Estas masas de aire que colisionan contra las laderas de las islas se componen de dos capas. Una húmeda, pesada y más bien fría y cargada de nubes que se mantiene en las cotas bajas y pegada al relieve (vientos alisios inferiores o capa baja, entre los 500 m. y los 1500 m. de altitud), otra cálida, más ligera y seca y libre de nubes, localizada en las cotas altas (vientos alisios superiores o capa alta, a más de 1500 m. de

South African Wave Energy Resource Data
A Case Study
May 2013
Dr. J. R. Joubert
Prof. J.L. van Niekerk
Summary
An assessment of the South African wave energy resource was conducted through the analysis of measured and modelled wave data. Wave data recorded at wave measuring stations, representative of the various coastal zones of South Africa, was evaluated and it was found that the southwest coast has the highest wave power resource with a median value of wave power of approximately 26 kW/m. A detailed assessment of the spatial distribution of wave power off the southwest coast was conducted and it was found that the average deep-sea resource ranges from 33 kW/m to 41 kW/m. Results of a detailed assessment of the wave

Monday, the U.N.’s Intergovernmental Panel on Climate Change is set to unveil the latest installment in its fifth assessment report. The last one focused on the science behind climate change; this new, 29-page report will detail its impacts, along with what we can do to minimize and adapt to the worst of it. Early indications suggest that the consensus will be cautious, but insistent: The effects of climate change are real, and we’re experiencing them now.
