IPCC delivers blockbuster report–No one important acted

The Intergovernmental Panel on Climate Change, IPCC, published its latest scientific consensus of projections of where climate change will take the planet. The short version: Unless we act quickly and decisively, the results will be even more catastrophic than we predicted earlier. In fact, the impacts of a 2° C increase in average temperatures, the former globally agreed-on target, are now recognized as being so concerning that the IPCC recommends restricting warming to 1.5° C. Here are selected responses to the report: ‘Incredibly grim’ prognosis on global warming also carries clarion call for global action–Los Angeles Times Opinion Piece by…

Climate change is here!

The most direct and tangible expression of global warming has been the intensification of hurricanes and typhoons. A very striking article explains why it has been so hard for forecasters to predict the big storms: warmer ocean surface temperatures and more importantly, warmer deep ocean temperatures, have changed the energetics of storms, so they don’t follow past patterns. As climatologist and hurricane expert Greg Holland explained last year, “globally, the proportion of Cat 4 and 5 hurricanes has increased from ~20 percent of all hurricanes to around 40 percent due to climate change over the past 60 years.”   Bottom…

Trump Administration acknowledges climate change

In a shocking new policy position, the Trump Administration claims there’s no point in higher efficiency standards for new cars and trucks for reducing GHGs. There’s nothing new in that. They offered a completely new reason, however: because the reductions won’t make a significant difference in a world that clings to fossil fuels. Of course, it is a self-fulfilling prophecy. NHTSA has put out a draft Environmental Impact Statement for its proposed CAFE standard that projects that in 2100, there will be 708 ppm CO2, 3.8 meters of sea level rise and 4 degrees C global temperature rise. It is already…
