Some charts worth studying. This all represents an updated version of the “business as usual” concept, and I believe it is considerably more realistic than most of the older versions, which show CO2 growing at a more exponential rate for decades ahead. BP has done us a favor in that regard. This new BAU is still fraught with risks, and leaves us pondering what can be done to reduce or eliminate those risks. Speeding up renewable penetration is one way, if that is physically possible from such a relatively small base. Another way is to put some brakes on the growth of total demand for energy, tied to slowing down the frenzied pace of global economic growth as we know it. Maybe that pace of growth is not a valid priority. Maybe there are other priorities.

Many sources of renewable energy do not have anything like these problems, and that difference should always be taken into account wherever choices of energy source are to be made.

A new study on Gulf Stream effects. It supports the idea that when the overturning of the Gulf Stream declines, as now seems to be the case, the process tends to pump more CO2 from the deep ocean into the atmosphere. This is not an intuitive thing for most of us to understand, so we are simply left with hoping it won’t go too far.
