Comment Re:It's about landmass (Score 1) 466

I've seen reports stating that EVs would suit 80-90% of the driving population because of their driving patterns. The majority of people do not do daily/weekly or monthly long journeys.
There are also reports that once a battery is "dead" for car use, it can be used as a house battery for solar because the draw on it is not as bad as a vehicle.
ICE will not die out but they might get pricier as less get made and economies of scale erode etc and might find it harder to park once more charge points take over the car park.

You are quoting todays battery prices as the price for 10 years time. Battery prices have already dropped dramatically in price in the last 5 years. Even if the price stayed the same for 10 years it will still be effectively cheaper. Plus by then they should be able to easily convert the car battery into a house battery for use with solar or wind.

from the first paragraph
"There is evidence that global warming has caused an increase in very heavy precipitation events--the kind most responsible for major floods"

from near the last paragraph
"Pollution may contribute to higher precipitation - It is possible that increased pollution is partly responsible for the increase in precipitation and in heavy precipitation events in some parts of the world. According to Bell et al. (2008), summertime rainfall over the Southeast U.S. is more intense on weekdays than on weekends, with Tuesdays having 1.8 times as much rain as Saturdays during the 1998-2005 period analyzed. Air pollution particulate matter also peaks on weekdays and has a weekend minimum, making it likely that pollution is contributing to the observed mid-week rainfall increase. Pollution particles act as "nuclei" around which raindrops condense, increasing precipitation in some storms."
from the last paragraph
"One of the few studies that did attempt to quantify flooding (Milly et al., 2002) found that the incidence of great floods has increased in recent decades. In the past century, the world's 29 largest river basins experienced a total of 21 "100-year floods"--the type of flood one would expect only once per 100 years in a given river basin. Of these 21 floods, 16 occurred in the last half of the century (after 1953). With the IPCC predicting that heavy precipitation events are very likely to continue to increase, it would be no surprise to see flooding worsen globally in the coming decades."
