“Extreme cold still happens in a warming world – in fact climate instability may be disrupting the polar vortex”
Since when is a “may be” a scientific conclusion?
Like I’ve said many times before this planet has gone through multiple cooling periods and multiple warming periods, This one is no different.
Warming oceans, changing currents, changing climate...The issue is not the changing climate, it is the speed and cause. Time will tell. 10 years max from now and we'll know how and why for 100%.

Did you also listen to the experts when they said that we were going to a global Ice Age back in the 70s? How about the experts that said that people who are vaccinated for Covid cannot contract the virus or spread it?
2 times NO... Of course there will be self claimed experts that have stated the above. People affected by confirmation bias will often refer to the statements of those "experts" and use that to deny global warming. The vast majority of the real experts will tell you a different story.....

Correct, some people don't know the difference between weather and climate. I'm sure experts do. I tend to listen to experts.

Have you also noticed that the climate cultist will claim that when there's high temperature records in the summertime that it's called climate change but when there's low record temperatures in the winter it's just weather?
No, low record temperatures in the winter is to be expected as well; weather will become more extreme during global warming.

Large volcano eruption can cause temps lowering.....true. We've indeed seen temps variations thousands of years ago but what has this all got to do with the current rise in temps? (The MWP is still questioned. Some say the warming was due to an increase in incoming solar radiation paired with a relative absence of volcanic activity.)
The other week a satelite was launched that will give us more insight in what is ausing climate change / global warming. We'll see who is right...I hope I'm wrong because that would mean hope for our planet...

How can you feel it yourself? You can actually feel a 1.6° c average change?
I haven't sensed any real cold temps in winter for at least 20 years. I went out in my sweater today with 15 degrees celcius outside, normally around minus. I've sensed an awful lot of wind and rain last winters due to warmer ocean and sea. I also felt a really long dry period in the summers. I'll be heading to Southern Germany soon where the current temperature in a wintersport area is 24 degrees celcius. This is the right temperature for july and august. I've seen glaciers disappearing, land being flooded, villages disappeared by enormous landslides. Permafrost is disappearing, rivers cannot be sailed in summer because of low water levels. Rivers are flooding in winter because of heavy rain that normally falls as snow. Storm barriers have to be shut more often because of extreme high tide and severe storms. Dikes are giving in, letting water through underneath because of water pressure. Sweet water inlets have to be moved landinwards in order to prevent taking in salt water. It is so obvious..

We are seeing all sorts of similar claims here in NZ. I blame media reporters and others who want to push a particular narrative (climate change, readership numbers etc) who deliberately distort, misreport, alter or change the emphasis of the facts to give more credence to their article. It is happening more often on a daily basis.
I don't need data to be convinced earth has become warmer, I can see and feel it myself. I don't know why some people still deny it. That however is something for psychologists.....

I think there's a reason that electric cars never took off at the beginning of the 20th century. There were too many drawbacks just as there are today.
It depends I guess...Over here 31% of all new cars in 2023 was an EV and hybrid cars 37%...
The proper infrasctructure is key though..

I think it only fair to point out that those short charging times you just stated, of around ten minutes, are only when you find a charging station that offers the Super Charging connection. Not all charging stations offer the Super Charging points, and I don't believe that there are any home charging stations that would offer such a speedy charge.
From what I understand, all home charging stations take hours and hour, basically over night, or as they state on their websites, a 12 hour charge to get a full charge, from a low battery starting point. Even the Super Charging stations can only give you a fast charge up to 80%, after which, the charging really slows down and takes an extended period from that point on, before it can reach a full 100% charge. Takes me only a few minutes to fill my tank up to 100% if it is almost empty.

I don't care my car is charging for a couple of hours at home. Power is free thanks to my PV system.
It's a choice...If it doesn't suit you, skip it.
We're producing so much solar and wind power in the Netherlands that on a sunny and windy day during weekends power will be free. It's time this overflow will be used to produce hydrogen in order to store energy.

What answers are you speaking of? It's a fact that most electricity is produced using fossil fuels. Unless you have some info that the rest of us don't know about, maybe. All these charging stations suffer under extreme cold weather, which a gas station does not. There are many news articles that tell us quite often users are stating that up to half of the charging points are often out of service, when they do find one. It's a fact that when an owner finds one, it will be several hours of charging time to get a full or close to it, charge.
Sure, you hear about the fast charge system that can give 60%+ in a short period of time, but that still takes far longer than a petrol/gas fill up. If you look into that fast charge, the manufacturers do not recommend fast charging as a way to do things. That is an emergency measure only, not a standard way to charge. The recommended way is still to charge over many, many hours, to get a full charge. Fast charges will eventually damage the batteries. Or maybe you dispute this too? Our neighbor says, for him, it's about 12 miles per hour, when he charges.

Some answers are in this topic. Yes, electricity is (partly) produced by fossil fuels. It differs from country to country. That for sure needs some work. However, how do you think petrol is being made? From green energy? This is being produced for 100% with fossil fuels. It takes quite some energy to refine crude / oil.
Charging in extreme cold takes longer, especially if the battery hasn't been pre-conditioned. That is the problem that made it to the news.
You will find some charging stations out of order. I've seen some over here in the beginning. Once enough people are using it more often, things will get better.
Yes, charging will take longer than a regular fill. However I never spend time filling my plug-in Hybrid with petrol. I charge at home in the evening and at work in the morning. Time spent: 1 minute total. For an EV even less time is spent unless you have to travel far which requires charging en route. (How often does this happen? For some more than others.)
Fast charging is not a big deal. A proper EV is designed to do that without issue. (Yes batteries wear down eventually) Clever software and cooling are protecting the battery preventing it from turning too hot. Charging is maximized in the beginning of the process and is gradually reduced towards fully charged status.
A modern EV, for example a BMW, can drive another 100 miles after 10 minutes of charging. Tesla 200 miles 15 minutes.
It really depends what trips you make on a regular basis. If you're driving + 400 miles/day, I wouldn't opt for an EV at this moment....
Lucian wrote:
You're forgetting the most important point here with an EV. How is the electricity created that will charge that battery every time? Fossil fuels, that's what is used to make the majority of electricity that charges those EVs. Of course then there are the hours of time needed to charge that battery up to full power, compared to 5 minutes max to fill up a vehicle with Petrol/Gas. Most people never think about these two things.
And then there is this to consider...
If you don't want to inform your self (or don't want read the answers already given) you won't find the answers.
This flooded Tesla charging area...Stupid to build it at a location that might be flooded. Just as stupid to build a gas station over there. Ironic side note: what is causing al these floodings..??
The biggest issue in my view is the scale of destruction and pollution all the current wars are causing.
I'm trying to live as green as possible but I'm starting to become a bit desperate and less willing to do my best...

You just go ahead and try an electric vehicle of any kind in Bozeman Montana in the winter.
In case you didn't see the news from Chicago Illinois a couple of weeks ago dozens of drivers were stranded when both their electric vehicles and their charging stations failed in the cold.
Just because something works in a flat relatively temperate climatebdoes not mean it will work everywhere else. I have nothing against electric vehicles other than the cost, but they are not feasable in some locations yetbour politicians are trying to force all of us into them regardless of if they will work in the real world that we live in.

You should read another post on this site explaining why EV's got stranded in the cold. (driver not pre-conditioning the battery). Norway is a good example. Lot's of EV's, lots of really cold weather, mountainous country. No problems there...Also US is a big country that also has flat areas and higher temps. Think in possibilities..
Let's be honest you have something against EV's. That's ok but don't tell me the concept isn't working.

Look at a map of the United States and one of the Neatherlands. Your country is flat and small. Just because something works in one part of the world does not mean it will work everywhere else.
For example cold kills lithium batteries. Mountains make lithium batteries less effective and running longer routes adds to the problems.
Don't tell me you don't have cities where electric busses can be used in the same way over here.
Long range obviously is not ideal for EV busses. Inner city however is perfect.
You're just looking for excuses to prove your point. There are solutions for EV to deal with cold environments as well.
Think in solutions. It's the only way forward.
