An update on the rapid progress of climate change in the Alps (OZY). Temperatures are rising twice as fast as the global average, “As peaks lose their shiny blankets of snow, which reflect heat, the darker colored mountains emerge and absorb heat faster, speeding up the process. Because of that, the Alpine region’s glaciers are expected to melt by the end of this century.” One observer has seen a 10% loss of glacial mass in the last five years.

Venice is being flooded badly by annual high tides (EcoWatch). “This year’s flood comes just one year after the city also saw major flooding in the fall…..St Mark’s Basilica is flooded for the second time in 2 years…..Before 2018, it happened 4 times in over 900 years.” There is great structural damage as a result.

The new World Energy Outlook 2019 was published today by the International Energy Agency. The full document is 810 pages long. This summary from Carbon Brief has a clear explanation of how the report should be interpreted, based on three different assumptions about how government policies will affect the future course of events.

A Canadian professor who calls himself a realist talks about the cold, hard facts that seem to elude the wishful thinkers of the world (The Tyee.ca). For example, he has a chart showing how the annual increase in demand for electric power is still greater than the total output of solar energy, by a wide margin. Moreover, “two years’ demand increase absorbs the entire output of solar and wind power combined.”
–Here is part 2 of the professor’s full report, which came in today. He describes 11 key steps that need to be taken if humanity really gets serious about slowing or reversing the damage being done by greenhouse gas emissions. (I have no argument with his way of thinking and analyzing.)
