Comment on Canada to announce all new cars must be zero emissions by 2035

• sj_zero ⁨1⁩ ⁨year⁩ ago

  Most people don't know anything about Canada, even people who live there. Most Canadians live in one of two megacities. They've never been to lynn lake, meadow lake, fort McMurray, fort st. John, or pickle lake. The wealth is extracted from these places, but with 0 understanding of what the country is like, particularly in February.

    I’d be curious to see electric car range in fort mac’s winter temps.

      EV performance in -40C is something nobody talks about but I'm extremely interested in.

      There have been lots of videos of Teslas leaving a heated garage then flying around a snowy track in Norway, but that's much different than getting in a car that's soaked in the cold all night, driving it to work, then driving home after it sits all day. Or even better, taking that same cold soaked car and driving to the next city 13 hours away with only one or two places to stop along the way.

        American here. Even in some northern US states we see - 20F in the winter.

        I currently live where winter includes below freezing all the time, with temps approaching 0F frequently. I have friends with EVs, who can’t use their resistive heat (worst way to use battery power) in the winter or they can’t get to work and back, so they conserve power for window defrosting only.

        We’re a long way from EV being viable. Wish people would admit that so we can have a proper conversation about it.

        I built a cattle water pumping system this year with Lifepo4 batteries instead of lead acid. It was awesome all summer, never had a problem with the batteries losing charge or getting too hot to work. But as soon as the temps started to hit 0, the builtin heater started to work in order to prevent battery damage (LFP batteries need to be above 0 for charging) when there was enough solar to charge. That battery drain absolutely floored the system and after the nights started getting to -5 or so, it was completely drained between the heater draw and the lower output efficiency.

        Cold is the enemy of high performance batteries, and LA batteries aren’t a possiblity in EVs.

        I imagine at -40°C, ICE cars also need heat or a garage

        I can only speak for Tesla, but if you have it plugged in overnight, you can schedule the battery and interior to come up to temperature by the time specified - you’ll be leaving on the trip with warm battery, warm interior, and a full charge

  I think we need to be realistic about what will actually happen. Climate change on the scale we’re seeing isn’t going to make the planet inhabitable.

  What will happen is that it will be a more hostile environment to live in. Climate change is resulting in larger droughts/famines in areas that aren’t used to it, as well as increased storms/flooding in other areas. Forest fires will get worse. Storms will get worse, species will die off, and if we don’t have enough food to feed large cities, many will die and governments will collapse.

  It won’t be the end of the world, but the world will not be the same because of it.

    Depends on what emissions scenario we end up hitting. Some of them are pretty scary. You can’t say you know what will happen bcz we don’t actually know how much CO2 we will have in the atmosphere in the next century, and climate change seems to be outpacing the models right now, so we really can’t say if it will be worse or not.

    I agree, most of what you’ve said is correct, but we cannot say it won’t be much worse than that bcz we just don’t know what we don’t know.

      What are some of the scary scenarios you have seen? I wouldn’t mind reading up on some good sources that would be useful to keep an eye on.

      Besides what we see in movies (unrealistic world ending scenarios), what I listed out seems to capture the realistic worst case scenarios that I have come across.

      I haven’t seen any projections that say that the atmosphere itself will become unbreathable (although we could see a lot more massive dust storms that would force people to remain inside or only go out with proper protection).
