The alarmists shouting about sea level don’t seem to know this. Strawman, it is the costs of all those efforts the ones that contrarians never add. Other economists helping climate researchers do and continue to tell us that it is foolish to not act to minimize the bad effects that will make adaptation much more expensive than controlling our emissions now. > **[The Climate Contrarians | S.

As I showed in my earlier pieces, if we use the standard statistical techniques for examining trends, then it is clear that the globe is warming, and in fact it has warmed faster over the period of the rapid growth in CO2 concentrations than in earlier periods. However, with a volatile series, such as the stock market or global temperatures, there are always periods of decline. But in both cases the trend has been upward and significantly so. > > The other point Singer makes is that “a modest warming is likely to be beneficial.” If he means a “modest warming” of 1/2 or 1°C, then there is evidence that the combination of CO2 accumulation and warming will have benefits in some sectors and in some regions. But we need to take into account the scientific evidence for “realistic warming” projected to be 3–4°C along with other geophysical changes—such as potential melting of the major ice sheets, rapid sea-level rise, and hurricane intensification—by the end of this century, if nations fail to take significant steps to slow climate change. The evidence from hundreds of scientific and economic studies finds serious to grave impacts on agriculture, coastlines and associated settlements, and ecosystems, as well as increasing acidification of the oceans and threats to many species around the world. > > Science progresses, the earth warms, glaciers melt, the oceans become increasingly acidic, but the climate contrarians change not. And that was William D. Nordhaus, who just became president-elect of the AEA. --- _[View the full topic](https://boards.straightdope.com/t/leaked-ipcc-report-90-confidence-in-agw-is-now-95-and-sea-level-will-rise/667002)._
