    True.

    The earth is in a warming phase. Some of that warming is (at least, probably) accelerated due to anthropogenic factors. This overall warming trend, however, does not result in everywhere getting warmer and dryer. This misconception, that everywhere on earth will experience a similar change, is the reason for the employment of the term 'climate change'. The results, actually, are not a uniform change in temp and rainfall. The results are, actually, a radicalization of local weather patterns resulting in the things Obama mentioned.


    A+ Good job, eco!
    Thanks


    There, homework done. You're welcome.

    More frequent and intense than what?

    Than in the last 100 years?
    Than in the last 10,000 years?
    Than in the last 1,000,000 years?

    My personal experience over the last 49.5 years, while living within a 25 mile radius of where I was born for most of it, is that yes, winters are warmer, there's been mark-ably less snow, flooding rains are happening more often, summers are hotter, bigger storms seem to be getting bigger and more frequent .....

    The last four could well be. Whether President Obama is more frequent and intense is between him and his wife.

    Perhaps so - but that really isn't the true question, is it? The real question is "are spikes in extreme weather attributed to anything man is doing or are they simply one of earth's many cycles and adjustments that have been going on for millions of years, well before man appeared on the planet"?

    It's false.And it's scientifically ignorant, because he's talking about the US ,which occupies a small part of the global land mass. But even there, he's wrong.
    Heat waves were way worse in the 30's.

    While details depend on many factors from geography, geology and such to methods and analysis, the science behind global warming evidence (anthropogenic aside) and the likely impacts is solid.

    One especially important factor to include is the El Nino cycle, as it is capable of disrupting (or enhancing) an overarching pattern.

    then why haven't there been been more floods, droughts, hurricanes, and wildfires? All because of the El nino?

    There have been, depending on ones parameters, time frame, methods, analysis, presentation and such.

    El Nino is a 7/14 year cycle with global climate impacts specific not only to cycle position but transition occuring. I'm merely noting a significant factor that should be taken into consideration regarding any temporal snapshot of climate related data.
