If you want some statistics to prove that climate change is real, here's one for you:

6 of the top 10 hottest global average temperatures have been the past 6 years.
8 of the top 10 hottest global average temperatures have been since 2009.
9 of the top 10 hottest global average temperatures have been since 2005.

This only goes back 41 years since we didn't track global temperatures before then. Whether you believe the climate models or not, you can't argue with these numbers.

Here's my source: https://www.cbc.ca/news/technology/w...2022-1.4784746

Even more interesting, is that the article says that "new research shows the Earth was actually in a global warming "hiatus" that is about to end. And when it does, natural factors are likely to help an already warming planet get even hotter over the next four years, according to a new forecasting model."

If that's true, then we are in for quite a change over the next few years! It'll be like when you go from a colder than usual period during late spring straight into a hotter than usual period. Yikes!

Here are some more numbers from a link in the article talking about hot hot 2018 has been:

Quote:
In the past two weeks, from California to Oman to Siberia, temperatures have soared, shattering records. Here's just a small sample:

Death Valley National Park, Calif.: 52 C (July 8)
Ouargla, Algeria: The highest reliable recorded temperature of 51 C (July 5)
Northern Siberia: Consecutive days with forecast above 30 C (July 916)
Chino, Calif.: Daytime record of 48.9 C (July 7)
Tajimi, Japan: Record-setting temperature of 40.7 (July 17)

The good news? This isn't anything climatologists didn't expect.

This year the world is experiencing a La Nina, the opposite of an El Nino, which actually causes cooling. The temperatures from January to May 2018 broke the record for a La Nina year.

June 2018 was was tied for the third warmest June in 138 years of modern record-keeping at +0.77C above the 1951-1980 baseline average. Only June 2015 and 2016 (+0.80C and +0.79C) were warmer.

I think I'll migrate. I was thinking maybe spending the winters in Tunisia and the summers in Sweden. Wait, isn't the EV scene great in Norway?...

Tomorrow, heat wave again. This time it's a regular heat wave, we'll have 35C. It's within my limits of comfort if I use the siesta hour correctly. Not another crazy, unbelievable 45C heat wave again. And it will take us away from the crazy mid-fall weather we've had this last week (22-25C highs...)... At least 35 is more normal.

Did anyone notice an impact on mileage in hot weather? Last few days we had temperatures reaching 95 F (35 C) here in north Jersey, and my mileage dropped from usual 55 to 51 mpg on my daily commute trips. I see the car switching to ICE almost always when accelerating even very moderately. Could it have to do with the BMS protecting the battery from overheating? The car interior gets incredibly hot when parked during the day, so the battery probably gets pretty hot, too. We had several heat waves this summer, and every time I noticed the mpg drop noticeably.

Disregarding temperature impacts on batteries, ICE efficiency peaks at 85 degrees and drops off either way. I can actually notice a difference on 70 versus 80 degree days after adjusting for speed and environmental conditions (about 2ish mpg). No experience yet above 90 degrees.

I think it's just your AC working harder and depleting your battery. It's electric in the hybrid, isn't it?

It works without ICE, also when the car is parked, so it must be electric. Not sure if it completely accounts for the spike in fuel consumption, though. The battery tends to stay charged closer to 2/3 range in hot weather, whereas in colder temps it stay closer to 1/3. The ICE engages much more easily, too, even with mild depression on the gas pedal.
