In many countries, it has been proven hard to implement policies that help electric vehicle (EVs). In France, fuel taxes have triggered huge protests . In Ecuador, huge protests followed a steep rise in fuel prices, as a result of a decision to end gasoline and diesel subsidies . An analysis conducted by Arctic-news compares eight policies on two criteria, i.e. how effective they are from a policy perspective and how popular the policies will likely be. As the image below shows, many policies are little or no better at helping EVs than continuing with business as usual (BAU). “Tightening fuel economy standards may aim to reduce fuel use,” says Sam Carana, editor of Arctic-news, “but the Jevons paradox shows that this may lead to people buying more powerful cars, drive longer distances, etc. Moreover, it does little to help EVs, in fact, it may make it cheaper for people to keep driving fossil fuel-powered cars. Sam Carana adds: “Subsidies for EVs aren't popular with pedestrians an...

Above image shows temperatures north of 80°N. The red line on the image shows the 2019 daily mean temperature up to Oct 13, 2019. The temperature is now well above the 1958-2002 mean (green line). The image also shows the freezing point of fresh water (273.15K, 0°C or 32°F, blue line). The freezing point for salt water is lower, at around -2°C, or 28.4°F, or 271.2°K. In other words, a rise in the salt content of the water alone can make ice melt, i.e. even when the temperature of the water doesn't rise. Above combination image shows forecasts for October 26, 2019. The left panel shows that air temperatures (2 m) are forecast to be 5.4°C higher over the Arctic than 1979-2000. Parts of the Arctic Ocean where there is no sea ice are forecast to be especially hot, since this is where heat gets transferred from the Arctic Ocean to the atmosphere. Anomalies are as high as 30°C, the top end of the scale. Temperature anomalies are in line with changes to the Jet Stream, as illustrated by t...
