World Is Finally Waking Up To Climate Change, Says 'Hothouse Earth' Author (theguardian.com)
The scorching temperatures and forest fires of this summer's heatwave have finally stirred the world to face the onrushing threat of global warming, claims the climate scientist behind the recent "hothouse Earth" report. Following an unprecedented 270,000 downloads of his study, Johan Rockstrom, executive director of the Stockholm Resilience Centre, said he had not seen such a surge of interest since 2007, the year the Nobel prize was awarded to Al Gore and the Intergovernmental Panel on Climate Change. The Guardian: "I think that in future people will look back on 2018 as the year when climate reality hit," said the veteran scientist. "This is the moment when people start to realize that global warming is not a problem for future generations, but for us now." The heatwave has dominated headlines across the northern hemisphere this summer. New temperature records have been set in Africa and cities in Australia, Taiwan, Georgia and the west coast of US. Heat stroke or forest fires have killed at least 119 in Japan, 29 in South Korea, 91 in Greece and nine in California. There have even been freak blazes in Lapland and elsewhere in the Arctic circle, while holidaymakers and locals alike have sweltered in unusually hot weather in southern Europe. Coming amid this climate chaos, the "hothouse Earth" paper by Rockstrom and his co-authors struck a chord with the public by spelling out the huge and growing risk that emissions are pushing the planet's climate off the path it has been on for 2.5m years.

Yes, it has been changing. But if you can look at that and aren't the least bit alarmed, I'm not sure anything is going to ever get through.
Even though I work with scientists, and one of my co-workers is an actual climate scientist(we discuss weather and climate a lot) I don't need scientists or science or empirical evidence. I've seen first hand how quickly the climate has changed.
A small town in the mountain west I grew up in was known for having very cold winters. Starting about 10-15 years ago, when I would visit in the winter I noticed it wasn't as cold. Anytime I mentioned this to my friends and relatives that lived there, they would say, "yea, isn't it great!". A few times I was there in January it rained, and not a little. Raining in January in a town that historically had brutally cold winters(avg high temp would be below 32 F, avg low temps between 0 and 10 F). This town used to have avg summer temps of around 85 F, now the last few years the avg summer temps in the 90s.
I've seen all kinds of new plants showing up, new weeds, just in the past few years. I've been landscaping and gardening for a long time and I take note of the weeds I have to deal with. I've noticed how bird migrations are changing, and different birds are showing up in my town.
If you live in the western US you've noticed that in the last 10-15 years the climate has markedly heated up and dried up. What used to be arid or semi-arid is now turning into full on desert.
We play the game with the bravery of being out of range
The same goes with flooding: the reason flooding seems to be getting worse is due to the destruction of marshlands and buffer areas and building hardscape surfaces on coastal areas. It has nothing to do with "rising sea levels" or anything else. You can't destroy the local environment and expect things to remain the same.
Whereas flooding IS made much worse nowadays compared to the past by the reasons you state above there is no reason to put "rising sea levels" in quotes. This is a known phenomenon. Even if you don't believe in global warming for whatever reason, sea levels are very accurately measured by satellites and unless all the global space agencies are conspiring to lie about sea levels*; sea level rising is a fact.
Coupled with sea level rising though, and perhaps a much bigger problem in most places is the fact that many coastal cities are sinking. With ground water being pumped out it causes subsidence- many cities are sinking at a much faster rate than sea level is rising.
* Which probably is more believable than believing global warming is fake- but still absurd.
"That's the way to do it" - Punch
How can it be taken seriously when they are constantly changing the historical temperature data to match their hypothesis?
"They" are not "changing the historical temperature data to match their hypothesis". That is a made-up alternate-fact being promulgated by the deniers.
You are referring, I assume to the Goddard Institute for Space Studies historical temperature record. The analysis of the data is exhaustively documented , including a FAQ giving an overview for popular audiences that are too bored to read the actual documentation. And the original data set, and all of previous historical analyses, are available on the web, showing that the changes in analysis technique don't alter the conclusion that the climate is warming. Here, for example, are the graphs showing the results of every different correction to the analysis, dating back to 1981.
In any case, you do know that several other groups, such at BEST, also analyze historical climate data, and come out with rates of warming that are essentially the same. So your conspiracy theory that scientists are altering their data in order to hoax the public is going to be a conspiracy of hundreds, and probably thousands, of scientists in independent groups on three different continents.
Nuclear power.
When I see new nuclear power plants getting built then I will believe that politicians and the public are taking global warming seriously. I have read some encouraging news recently that US federal regulators are making real investments in the future of nuclear power. There's already been a shift in how nuclear power is viewed, and people are starting to embrace it again. One real reason people are embracing it is very self serving, a lot of nuclear power plants are reaching end of life and will be shut down soon and without a new reactor in its place a lot of jobs will be lost as well as a large source of electrical generation capacity in that region.
I don't much care why people are embracing nuclear power, only that people embrace it. Nuclear power is safe, low carbon, domestically sourced, and inexpensive.
Say what you will about past accidents with nuclear power, like Fukushima, Chernobyl, and Three Mile Island, all of them are irrelevant to embracing third and fourth generation nuclear power. All of those past accidents were with second generation nuclear, and as safe as second generation nuclear power has been on the aggregate we will see even safer power with third generation nuclear that is being built now. Fourth generation nuclear, such as molten salt reactors, will be safer still.
I've seen the numbers and models on a national grid based on wind, water, and sun. This is not a future with inexpensive, reliable, and safe electricity. It's quite likely not low in CO2 either. There is no future with inexpensive, plentiful, safe, clean, and "green", electricity that does not include nuclear power.
Here's a couple websites that do the numbers:

well-verified models that have been vetted and analyzed
The models have consistently over-predicted temperatures.
to the contrary, the models have fit the data to well within confidence limits, and continue to do so.
Here's an article from Forbes about the very first Global Climate Model, Manabe and Wetherald 1967, looking back at how well their predictions from fifty years ago compared to data: https://www.forbes.com/sites/startswithabang/2017/03/15/the-first-climate-model-turns-50-and-predicted-global-warming-almost-perfectly/
And here are graphs, showing that the prediction from fifty years ago (red line) fits the data (blue line) almost exactly. https://climategraphs.wordpres...
Later models have refined Manabe and Wetherald 1967, incorporating other effects than simply carbon dioxide and water vapor, but haven't changed the answer. Here is the Berkeley Earth page comparing climate models used in the IPCC report against data: http://berkeleyearth.org/graph...
The problem with the deniers, on the other hand, is that they don't have a prediction. They don't have an alternative model, they don't have anything.
