Are we experiencing exponentially increasing sea level rise?

Guest post by Alexander Ač9 October 2015 (Desdemona Despair) – Sea level rise (SLR) is recognized as one of the least adaptable impacts of ongoing climate change. Once a certain area is permanently flooded with saline water, people have to leave. Forever. Thus SLR projections gain a lot of attention not only in the climate […]

Scientists say dramatic worldwide coral bleaching event is underway, beginning in 2014 with ‘the highest thermal stress we’ve ever seen’

By Chris Mooney8 October 2015 (The Washington Post) – For just the third time on record, scientists say they are now watching the unfolding of a massive worldwide coral bleaching event, spanning the globe from Hawaii to the Indian Ocean.
