“2019 in review: Polarised world entering era of climate impacts” (Climate Home News). The past year saw a great collision between political and physical forces. “As 2019 draws to a close, the rift between the climate vanguard and the laggards has never been so wide…..Meanwhile, scientists continue to warn of a narrowing window of time to act.” With vital issues becoming more and more clear, all the big moments that happened over the year are drawn together very nicely in this report. “Indeed, the year ahead is critical for climate action and the spotlight will be on governments to increase their climate plans. Much expectations lie on a key EU-China summit in September that could see the world’s largest emitter promise to enhance its climate target alongside Europe.” (Just two months before the US election!)

“Canadians want more action on climate change, but are worried about economic hardship” (Global News). This story was based on the results of a poll taken in Canada, results of which would probably have been very similar in the US and many other economically developed countries. The high standard of living we all enjoy, together with lots of well-paying jobs, is largely based on copious supplies of cheap energy—of the wrong kind. What if it is actually impossible to simply switch to other energy sources and keep going on as before, without interruption? If time is really running out, as scientists are saying, the public could be forced into making a decision that will probably not be easy.

“Global consumer demands fuel the extinction crisis facing the world’s primates” (Mongabay). “Commodity production, extraction, and consumption are taking a heavy toll on key primates habitats around the world…..A ceaselessly growing human population and an ever-expanding world economy based on the unsustainable demands of a few over-consuming nations, have already caused habitat degradation, forest fragmentation, and forest loss that are unprecedented in human history…..the IUCN Red List reports that some 60% of primate species (more than 300) are now threatened with extinction and roughly 75% have declining populations due to human activities.”

A new study finds that approximately 5000 Himalayan lakes are unstable, at risk of outburst flooding (Phys.org). Lake waters are held back by barriers made of loose rock and dirt held together by ice. Glaciers are melting and the lakes are growing, putting pressure on the moraine barriers, some of which have already burst. “They note that prior research has shown that up to two-thirds of Himalayan glaciers are going to disappear in the next decade, indicating that a lot of water buildup in lakes is going to pose a serious threat to those living downstream.”

Replacing fossil fuel with hydrogen for transport, heating and industrial processing is the secret to a 100% renewable system. It’s still prohibitively expensive, but there are good prospects for costs to fall sharply from here.
