Is the Rise in Global Temperatures Slowing Down?

An Economist article asks whether the flattening of the rise in world temperatures in the past decade, while carbon dioxide emissions were increasing, shows that the predicted rise of 4 to 6oC in this century is off base.
Response: No, unfortunately.
Carbon dioxide (CO2) emissions do not heat the earth immediately. We are told that there is a 15-year time lag between their release and when temperatures begin to rise. So the leveling of world temperatures in the past decade makes perfect sense. In 1988 the economy contracted and for the next decade GDP was lower and so were CO2 emissions.
With CO2 emissions rising by 4 parts per million per year in the 2000s, it makes sense to expect a marked increase in extreme weather by the mid 2020s and beyond.
Investors who wish to direct their energy portfolio into solar, wind, geothermal, grid, algae, batteries and other green technology, would be advised to lobby for a carbon tax to allow promising green upstarts to compete successfully against the aging fossil fuel industry.
