Yes, one or two degrees is. Water in the summer time gets warmer but always returns to a cooler temp. I live in an area of the planet where because of the warmer temps, all the coral which supports fish life are dying off. Fish die, then we will starve.

Climate scientists know that the earth has been cooler and warmer and the the sea levels have been 130 meters lower and 10 meters higher in the past. That's why it took so long to provide the evidence that the current trends are not natural, but caused by a man-made rise in CO2.

However, it's good to look at the deep past, because then we understand the consequences of previous climate change periods (that were not man-made).
Some of those periods caused mass extinction on earth. Nature has always recovered, although most times completely different. Several times, over 90% of all species died out. Back then, nature was flexible, but now nature is already incredibly weakened by humanity. An extinction event of previous magnitudes has the potential to wipe out all life or just leave the simpler life forms. In any case, the end of humanity.

Just because something is complicated, does not mean we know nothing about it. In 2019 the evidence for climate change has reached the "gold standard" level of certainty.
That means there is more than 99.7% certainty that it's true. Actually, the five-sigma level means there is only a one-in-a-million chance that the findings are just a result of random variations. It will never be 100%, because science doesn't do absolutes.

The rising sea levels are only troubling for the next generations. Our generation only has to worry about increasing droughts, wildfires, floods, hurricanes and tropical diseases migrating to the north (also to the south, but 10-12% people live on the Southern hemisphere).

Climate science also tells us that there is only a short window left to prevent an unstoppable chain-reaction. So you can wait until everyone is convinced, but that probably means that it will be unstoppable then, even if we completely ban all technology. The current renewable energy technology is not intended to destroy our current way of life, it's the last straw we grab to retain our current way of life.

Even if climate change wasn't man-made, it would still be caused by to the current unprecedentedly high levels of CO2. And then the only solution would still be to lower those high levels of CO2. And that would still result in the same solutions, lowering human emissions of CO2 and re-planting trillions of trees or find other ways to absorb CO2 out from the atmosphere and ocean. And it would still cause massive climate catastrophes, of which we have only seen the beginning yet. So, even if it wasn't
man-made, we would still need to stop it, to save humanity or at least human civilization.

It's not a gravel path made by humans 2000 years ago, it is a 'path' over the glaciers now, that modern people use to get to ski and hike locations. They are not saying that it was ice free 2000 years ago, they are saying that it is the first time in at least 2,000 years that is now free. When it's not possible to determine for longer ago than 2000 years, they say 'in at least 2,000 years'. They do however say 'The Alps' glaciers are now on track for their biggest mass losses in at least 60 years of record-keeping, data showed.'

Do you think that people 2000 years ago were carrying gravel up the mountains? Do you imagine rows of people with donkeys, going up 2800 meters in the alps to lay down a path?
For what? Was it a popular ski resort back then? The population of earth was around 180 million people back then, 1/43 of the population now. They were mostly farmers in little villages. They had no reason to go up 2800 meters up any mountain, whether covered in snow or barren rock. Only bored modern people do that.

By the way, some glaciers are 5,500 years old, some are 10,500 years old and some are 30,000 years old, and they're all melting at a rate than ever before, for so far it's determinable.

2000 Years ago, it was a little colder than the past 2000 year average. Some sites show a graph of the last 2000 years, with a peak at around 1000 AD, the medieval warm period. However, they cut off the last 100 years and stop at 1900, to obfuscate the massive spike of the last 50 years or so.

Here is a nice example of dishonesty:

Why the fuck do they draw a DOTTED LINE, for the most reliable data?
That dotted line starts around 1920 or so and ends before the year 2000, to make it appear that it was warmer 1000 years ago. And this is not even the worst disinformation site out there.
However, they are hiding the fact that we are now up to around +1.2°C and the medieval warm period was at max +0.55°C.

True, Trump warned us against buying natural gas from Russia.
Did he advise us to accelerate the energy transition, so we are no longer
dependent on Russia? Because, I've never heard him say that.

That's the only way to not be dependent on outsiders for our energy needs.

How many time do I need to explain to you that all transportation is only 24% of the total global CO2 emissions and cars are only 41% of that. You are talking about 10% of the problem. Solving that problem will not save us.

The production of the current electric cars is emitting lots of CO2, because they are making mostly high end cars like Tesla's now. Only when normal people can afford simple, cheap electric cars, will it have any significant impact on climate change.

Climate change can only be solved by the energy transition of companies and houses, reducing emissions from agriculture and turning DEforestation into REforestation.

You should have done that a few years ago, when it was cheaper and the solar panel installation companies could still find employees. When I bought mine, electricity was $0.22/kWh and natural gas was $0.70/m3. Today electricity would cost me $0.89/kWh and natural gas would be $3.94/m3. That's four times the price for electricity and 5.6 times the price for natural gas. No energy provider is giving out contracts at the moment. My contract will end in December, the worst month to sign a new contract. So I probably won't be able to do that and get billed the flexible price, which will probably cut into my savings a lot. Or I will just have to sit in the cold and find another hobby than gaming.

I'm very happy with my solar panels. Just a shame they don't do much in December when my contract ends. However, if the current price keep up, my solar panels will make me $2,330 per year and they will have payed for themselves by June 2023.
But, I think electricity prices will increase even further.

There are no reliability issues. The only thing that isn't reliable is the sun, but the yearly production only differ by at maximum 10%.

A very affordable and cost effective investment is sun protection window film. It can keep out almost 100% of the infrared and up to 89% of heat radiation. It will keep your house cool in the summer and warm in the winter. It will reduce energy costs for cooling and heating. I'm requesting quotations at this very moment.

I'm also looking for prices of air conditioning systems. I don't even really need it for cooling, because my rolling shutters helped a lot this summer, but it's the best solution
for electric heating of one room in winter.

At the moment, maybe. When horse and buggy was the thing, gas stations were not common and people would say cars were a toy for the rich. At the momen hybrid cars are all over the roads and with better batteries, soon, electric vehicles will be useful ( reliability is another thing, just remember the Edsel)

And what if it doesn't? Will you find something else to introduce the Boogeyman to us?

I really enjoyed this video.

As soon as I understood that it was Bill Gates, I was anticipating the 'vaccines to reduce the population' argument. I didn't have to wait long. Shall I explain it again?

And off course; "Vaccinate, tag and digitally track each one of you like livestock.."
Why use vaccines for that? You are already wearing your tracking device around,
in your pocket. They either think of you as too dumb to realize that or they are obfuscating what the NSA is doing. What is their motive to do that?

"Not only will my organization enjoy legal immunity and trillions in profits.."
Which is the party of deregulation and tax-cuts for corporations again?

Celebrate with his friend Jeffrey Epstein on his Lol.ita express?
Together with Trump, I presume? With girls recruited by Matt Gaetz.

"Surrender your personal freedom and common sense to our fear merchants in the government and the media"
Wow, exactly what Republicans are doing. Very insightful!

reflect the heat away,keep it cool!

And has been for millennia. And would continue if the human race went extinct in the morning.
