2) However, that line is largely erroneous, because it is only the affect on humanity & the effects by humanity which are of interest, for us. In this respect, WE (humanity) have only recently (the last 200 years) grown into numbers sufficiently large, where our sheer numbers could have any substantial effect on the Global Environment AND where "some" of those Global Climate Changes will then have a substantial affect on us, because we now inhabit so much of the planet & that the density of our habitation is now so great, that these changes have so much greater affect now, than at any previous stage of our relatively short "occupation" of this planet.
3) So, whilst the Climate has always "changed", we have not been around long enough for those changes to materially affect us, except for the last Ice Age, which nearly saw us become extinct!
4) As can be seen from the above chart, we are now at or approaching the top of the current warming phase, so unless our involvement kicks us completely out of the usual cycle, we will start into the next Ice Age part of the cycle, in the not too distant future. In the mean time, we will hit Peak warming & with that will come some Peak weather/climate events, such as extra strong storms, floods and droughts just to mention a few, plus likely large rises in sea levels.
Whether anyone believes in human caused climate change, is largely irrelevant, we are now at the infection point when change will happen anyway and if it does happen over the decades ahead, as seems likely from the best current scientific & anecdotal evidence, then it will happen at a once in history time for humanity, just as our Global Population has acquired "maximum carry capacity", so the outcomes will also reflect our exposure & probably our lack of mitigation against the risks!
Oh & it is also interesting how little comment there is, concerning the human element of the current event/disaster, with deaths expected to number in the many thousands, damage expected to decimate entire regions and peoples well being for quite some time & no, I have not yet heard from Ferdinand!
And I'll re-post my answer here too as it is relevant. In reference to your last comment you might read earlier in your own post ie lots more people = lots more people effected = lots more deaths not necessarily and in all probability NOT more severe events. The US city of Galveston in 1900 when there were many fewer people, was hit by a hurricane that caused about 10,000 deaths. If such an event were to happen today you would really have something to lather up about but the truth is had that happened at that time where the current one hit you would have never known it had ever happened. All this is is opportunism, anecdotal conjecture and finger pointing...100%....science...0%.But hey who needs science when you can suck the marrow out of events like these. I'm sure if you look hard enough you can post a picture or 2...maybe a drowned kid face down...that would be a coup...plenty of mileage there! Such an event, just did happen!
It is not anecdotal, it is not finger pointing... 0%, it is Fact ...100% and now is the appropriate time to review our risk mitigation, because if we leave it until the outcomes are absolutely obvious, then it will be far too late and we maywill have given any chance of avoiding the worst outcomes! Come to think of it all the extra weight from all those extra people is probably causing worse earthquakes and the resulting tsunamis.
