"Half of the increase in atmospheric carbon dioxide concentrations in the last 300 years has occurred since 1980, and one quarter since 2000."

The conversation about global warming needs to be cognizant of the fact that even if we somehow were magically able to stop all man-made sources of CO2 today, global warming would continue for a long time, since the half-life of CO2 in the atmosphere is about 100 years. Not to say that we should stop our efforts to curb green house gas emissions, but if we want to stop global warming, we would have to make massive efforts to go carbon negative, not just carbon neutral.

Predictions like this can never be wrong! What a great job. You can never be wrong. They COULD see a century's worth of sea rise in just 30 years, but on the other hand, they might not.

He'll be denying science even as he floats out the front door of his home on his sofa due to a flood, lol. The head in the sand not my problem ideology I saw during the pandemic, the denial of science, the complete refusal to understand that everyone is tied together whether they like that idea or not, makes me very pessimistic about the future.

U.S. coastline **COULD see a century's worth of sea rise in just 30 years**

To be honest, I don't think scientists understand all the factors that affect climate change. They keep finding new things that have not been included in their models.

And, although models can be useful and helpful, they are not necessarily right. Making models is not the same thing as actual experiments. In this case, it's the best we can do, but the point is, models are not as accurate as real science done with the scientific method.

This model makes a number of assumptions that cannot be proven - the main one being that things will continue over the next 100 years as they are today. But we don't know that. The climate has warmed and cooled all on it's own in the past.

Another assumption would be that we have a good understanding of what effects temperature change in our world. If past models are anything to go on, I think it's wildly clear that we do not understand this stuff very well.

I was glad to see this article highlighted on this site the other day: https://japantoday.com/category/features/environment/don't-just-blame-climate-change-for-weather-disasters

These days, anything and everything gets attributed to climate change, but that's sloppy science - as this climate change scientist himself points out.

Personally I tend to take predictions like this with a grain of salt.

We both know @Farmboy 5:51pma tall hill in Kansas“ can also be a dangerous place.

Global climate change is present now - and has been an ongoing problem. Sea level rise is measurable and observable. Shrinking arctic ice which impairs the Albedo effect is easily discernible and documented. As is other evidence of global warming and rising seas.

It can be mapped out using current and past data.

None of which is propaganda. Ignoring ever-present realities is not an effective stratagem. It leads to a larger disaster.

Among other effects: it will impair agricultural production aka our very foodstuffs. Focus on that: famine.

Among other evidence, one can literally watch islands and atolls disappear beneath the waters.

Osaka and Tokyo have mapped out the impacts of flooding and engineering projects have taken place which intend to mitigate flooding due to increasing sea level. But, at his point the impacts are not reversible, though thru very certain measures there can be a lessening of larger impacts.

The coastlines haven't changed.

I have some attractive property to sell you in the Miami area.

You'll see that all the climate models predicted that half the world would be under water by now.

Climate models 20 years ago were not predicting half the world would be under by now.

You misrepresenting what the science was saying is what is total BS.

GM and Ford will have to start making floating SUVs. Nice big V8s and not electric ones because 440V and seawater doesn't sound like a good mix. Water has lots of drag, so a boxy thing will need a ton of torque.
