Even if you concede the accuracy of published global temps, this report, at least, fails to cite a time frame within which these catastrophes are to befall us. The language such as "could reach as high as..." and "...is projected to be, if current rates of change continue," takes us from purported data accuracy to speculation.
Having lived on or near the ocean practically my whole life, I have seen little, if any, change in the sea level. Sure, beaches and coastline disappear. Storms, tides and currents take them away and usually return them the next month/year. The sand is washed out a ways and then is washed back in. You can see it.
I know what you're going to say, "C'mon, Russian, you know anecdotal observations don't count." But, if observed sea levels don't differ from one decade to the next, how do you argue that they do, unless you hypothesize that the oceans don't balance themselves and between one and another. Or, are you saying that the Pacific might be 5 feet higher than the Atlantic, for instance.
As to the econ impact of higher air temps, say, we had a dust bowl in the 30's and now we don't. CO2 (the boogeyman) levels, in addition to being made the whipping boy, have created at least part of the conditions under which global agriculture has improved and the general coverage of vegetation has increased.
Nature changes on its own, by virtue of a complex interaction of global and extraterrestrial forces. No one is anywhere close to modeling it all. How anyone can claim that a 1% change in a factor that represents only 4% of that factor in the total of only one of the many forces (atmosphere) is a mystery. Unless...
