#3Forecasts for +10C in Oslo Norway the next days, possibly melting all the snow and ruining skiing in the forests during lockdown, my best reason to go outside at the moment..

Too bad you can't go skiing, but I'm a bit more worried about plant and wildlife that "thinks" it's spring and then will get killed when it gets cold again later.

#5Since 1940. Or 1958. Or is it 1995?
Why does the graph have 2 colors? Why is 1995 'zero'?
Re: World ocean temperatures in 2021 were the hottest ever recorded
#6Chart has baseline at ~1995. They say we reached 200 zettajoules around 2019.
200 zettajoules => 2.0e23 J * 4.184 J/cal => 8.36e+23 calories
They say this is the energy absorbed by top 2000 meters of the oceans. There are 84.8 million sq km of ocean.
2000m * 84.8e6 => 1.69e20 liters of water.
1000 calorie to warm 1L of water by 1 deg C.
1.69e20 L / 8.36e23 cal => warmed by 0.2 deg C since 1995.

#8Not only does science show the current temperatures are getting hotter than ever. We now know the past 50 years was colder than we ever thought. With new advanced scientific techniques, we now have a much better idea what the temperature was 50 years ago than they did 50 years ago.
It should be kept in mind, these new temperatures measured now are not breaking records compared to the temperatures measure 50 years ago, but rather to the modified and corrected temperatures of 50 years ago.
Here is a great little collection showing how the temperature records change over time.

#9I have the feeling that many people (especially politicians) think that global warming is a linear process. It's not. It might even be exponential since some sources for climate-warming are affected by warmer climate. For example, melting ice that reflects sunlight back to space [https://arcticwwf.org/places/last-ice-area/].
I'm thinking about choosing a new place to live right now. Climate change is a big factor for that.

Of course. And I also know a single instance isn't proof of climate change. But I wanted to point out / rant about how the winters have changed over time here. It's sad.
And summers hotter than ever. Have had to buy AC, as if we're in Southern Europe.
