Conditions in Indonesia‘s major agricultural regions will likely be drier than normal this year, the president warns. Hawaii faces a variety of flooding threats in coming years. The Tampa Bay area could face water-use restrictions as dry temperatures persist. Three of the U.S. Great Lakes, along with Lake St. Clair, set new record-high April water levels. A new study warns that unbearable heat, comparable with temperatures in the Sahara Desert, will affect a third of the world’s population by 2070.
“This is significant because many people think that sea level rise can be mitigated by seawalls. But a seawall will not stop groundwater inundation. Our results highlight the need to readjust our thinking regarding the flooding that accompanies sea level rise.” –Shellie Habel, lead author of a study by the University of Hawaii that details future flooding risks in the state. The study found that rising sea levels will cause direct shoreline flooding, but also flooding via groundwater inundation as water tables rise. The study warns that flooding could be caused by reverse flow through the municipal drainage system as well. University of Hawai’i News

Science, Studies, and Reports
A new study published in the Proceedings of the National Academy of Sciences explores how climate change will alter the human habitat, and the results indicate that 1 billion people will face insufferable heat for every 1°C (1.8°F ) rise in global temperatures within 50 years. According to the most optimistic scenario, by 2070 a total of 1.2 billion people will be pushed outside the “climate niche” in which humans have lived for the past 6,000 years. The study estimates that residents of India, Nigeria, Pakistan, and Indonesia will face the most extreme temperature changes. The Guardian
