Rio’s famous beaches take battering as scientists issue climate change warning
Scientists in Rio de Janeiro have warned that the city’s sea defences may not be able to cope with the effects of climate change after a record storm surge swamped beaches, dumping hundreds of tonnes of sand across nearby roads and buildings. This shows the high degree of vulnerability to climate change in Brazil, which has 7,400km of shoreline and 25% of its population living on the coast.
New, Space-Based View of Human-Made Carbon Dioxide
Scientists have produced the first global maps of human emissions of carbon dioxide ever made solely from satellite observations of the greenhouse gas. No satellite before OCO-2 was capable of measuring carbon dioxide in fine enough detail to allow researchers to create maps of human emissions from the satellite data alone.
Before and After Photos: SE Beach Dunes Lost to Hurricane Matthew
New low-altitude aerial photos of Southeastern beaches taken before and after Hurricane Matthew passed offshore show a new storm-cut inlet, and roads, dunes and structures lost. Hurricane Matthew’s storm surge and waves overwashed about 15 percent of the sand dunes on Florida’s Atlantic coast, 30 percent along Georgia’s coastline, and 42 percent of dunes on South Carolina’s sandy beaches.
