Climate Letter #1221

How big is the threat of Arctic exploration for oil and gas?  This post has a somewhat dramatic collection of interesting pieces of information, not all of them necessarily credible, but enough so to indicate that the targets are very substantial in size and likely to be profitable.  That kind of thing will always attract big money interests that will do whatever they can to go after it.  There is strong opposition to Arctic exploration and production just for highly sensitive environmental reasons, but is it strong enough to prevail?  The story is still unfolding.

The Brazilian government is reported to be lowering environmental standards, thus allowing an increased pace of deforestation (Mongabay).  This is a problem that affects the entire world, but the rest of the world has little power to do anything about it, nor, apparently, do the Brazilian people who care.  Brazil is a central figure in the existential deforestation threat that was described so well by Fred Pearce in yesterday’s Climate Letter.  (The Brazilian president, of course, is not the only one who behaves in this manner.)

There are good arguments supporting the additional employment of nuclear power for electricity.  This article from Yale e360 expresses them as well as anything I have seen.  Any opposition that is based largely on irrational fears needs to be reconsidered in this light.  Renewable energy sources, even if more desirable, can always use some help in speeding up the much-needed transition away from fossil fuels.

Climate change had a major role in the horrific Greek wildfires.  It began with an unusually dry winter.  More recently, “the contributing factors included drought, strong winds and unusually high temperatures, all of which are likely to be aggravated by climate change.”  These same conditions “are likely to be replicated more often in the future.”

Arctic Sea Ice Extent—an indicator that now needs to be closely watched.  Mid-September is always the time for reaching maximum ice retreat, so the next six weeks are critical.  This year’s track, fairly benign so far, is just now giving indications that it may follow the type of extreme plunge experienced in 2012 when brutal wind conditions churned up the ocean’s surface.
