    The graphic above shows why: Most of the state’s hottest and driest years have occurred during the last two decades as well.

    Over the past century, California has warmed by about three degrees Fahrenheit. That extra-warmed air sucks water out of plants and soils, leaving the trees, shrubs, and rolling grasslands of the state dry and primed to burn.”

    You also have studies that show that hurricanes already becomes more destructive becaues of climate change.

    One research team’s results, accepted for publication in Geophysical Research Letters (GRL), found that in comparison to a typical 1950s hurricane, climate change likely increased Harvey’s seven-day rainfall by at least 19 percent. A separate study, published today in Environmental Research Letters (ERL), found similar results, showing that climate change boosted Harvey’s three-day rainfall by about 15 percent.

    Both studies also found that climate change roughly tripled the odds of a Harvey-type storm.

    “It is not news that climate change affects extreme precipitation, but our results indicate that the amount is larger than expected,” said Michael Wehner, a climate scientist at the Lawrence Berkeley National Laboratory who coauthored the GRL study, in a press release.”

    Remember when we were told that wildfires would increase due to global warming? Never mind.

    This paper was just published in the Royal Society Biological Sciences journal. The takeaways: “Global area burned appears to have overall declined over past decades, and there is increasing evidence that there is less fire in the global landscape today than centuries ago.” Global trends in wildfire and its impacts: perceptions versus realities in a…

    Also that our human societies are very vulnerable to climate changes and extreme weather. For example the 10 worst climate driven disasters during 2018 cost 85 billion dollars.

    https://www.forbes.com/sites/davideb.../#5c9f6a412680

    There manmade global warming will lead to climate driven disasters become more common and costlier. There you also will have a lot of other negative effects from manmade global warming.

    https://climate.nasa.gov/effects/

    https://royalsociety.org/topics-poli...s/question-17/

    While you can also combine action to combat manmade global warming and toxic pollutants with a strong economy. For example Sweden is one of the most sustainable countries in the world that implemented a carbon tax as early as 1995.

    While also ranking second on Forbes best country for Business list.

    https://www.forbes.com/best-countrie...business/list/

    Also having countries, communinities, corporation and individuals leading the way in the transition away from fossil fuels have drastically reduced the cost of renewables. So that even Republican politcians are on a local level starting to see the benefits of renewable energy.

    https://www.forbes.com/sites/joshuar.../#631e530f3da7
    When a solar powered 747 takes flight, we can discuss the reliability and usefulness of renewables in industrial applications.

    Until then, it's an interesting possibility for the future.

    However, you have taken the leap from "what if" to "omigod"! The what if is "What if CO2 is the direct causal driver of warming".

    The problem with this is that in the real world, this is not shown to be a direct causal driver.

    You and others present this as a natural certainty and yet the certainty seems to not exist. Gravity is pretty certain on and around this planet in broad terms and can be demonstrated to have occurred in the past, in the real world, as it does today.

    The Causal link between increased CO2 and runaway global warming is not so demonstrable. In the past, Scientists tell us that it was much warmer with much LOWER concentrations of CO2.

    IF there is a direct, unbreakable causal connection, THEN this is impossible. Yet it happened. Care to explain?

That Bush was president for eight years and Trump have been president for two years so they could have directed goverment funds to disprove manmade global warming if any evidence had existed.

    I have also provided direct links to fossil fuel companies' websites there they states that manmade global warming is real. What reason can they have for doing that beside the overwhelming evidence for manmade global warming?
    Are you seriously asking that a negative be proven?

    The onus of proof is on those that are demanding action to fight this thing that does not exist.

    Coulda, Woulda, Shoulda is not evidence, it's a list of excuses.

    It's interesting that the cost of the disasters increases as the intelligence of the residents falls.

    Hurricanes hit the coast. Without cities on the coast, no problem.

    Fires burn the drought dried underbrush. Without 20 million people living in the Los Angeles area's drought dried underbrush, no problem.

    When the evil white man arrived, the Native Americans did not live on the coasts or overpopulate areas that could not support the indigenous population.

    We are working against nature and wondering why it doesn't work.

    The simple truth of the whole thing is that we are fleas on a dog arguing about which way the dog should run.

    I highlighted an interesting part of your post.

    They did not, presumably could not, accurately predict what actually happened.

    In the real world, this demonstrates their lack of credibility.

    More hype from used car type climate change salesmen looking for big government funding boosts to their troubled life's work believing and promoting impossible fixes to fake problems based upon bad science predictions.

    The cost of sever storms hitting the coast will continue to rise.

    This is because we keep building expensive things on the coast. And insuring them.

    Sea level change has not happened to any significant extent.

    Storms have in fact become less abundant.

    You are streatching anything to fit your bankrupt naritive.

    It wasn't the changes in forrest management that had this effect then?

    Although I am a fan of Trump, I don't think he is taking this issue seriously enough.

    I am convinced the base of this problem stems down to the population size. The more of us there are, the more natural space we require, the more resources we need, the more transport we need, and the more emissions we create. Animal farming takes up an enormous amount of space, and in it's self creates large amounts of emissions. Of course, there is the ethical debate regarding the breeding of animals so we can shoot a bullet through their head, but that's another argument for another day. Other than China, it appears that no government of any significant country wants to address the problem. We all know that the worlds population is ageing, and that in turn means we need more young people to even up the balance. However, those young people will also get old, and the problem get's worse and worse. I don't claim to have the answers, but I am aware there is a problem. What is frustrating is that governments know we have this problem, but none of them have the bottle to do something about it because they are so damn scared of upsetting people.
