Algal blooms are getting more severe in lakes all over the world (Carnegie Institute for Science). This has been demonstrated for the first time by a survey based on thirty years of satellite images. While different factors have affected different lakes, one clear finding was that “among the lakes that improved at any point over the 30-year period, only those that experienced the least warming were able to sustain improvements in bloom conditions.”

Glaciers in the Swiss Alps are shrinking at a record rate (Phys.org). According to an annual study, “Switzerland’s glaciers have lost a tenth of their volume in the past five years alone—a melting rate unmatched during observations stretching back more than a century.” A separate study has indicated that over 90 percent of some 4000 glaciers in the Alps could be gone by the end of this century.

The overall index has shown a trend of improvement since the year 2000 but a number of countries have fallen behind. Nearly all countries that have problems lie within the tropical zone, are poor to begin with, and are being affected by drought, often accompanied by conflict.

Shell Oil has an interesting way of looking at the future (Reuters). The company CEO says it wants the world to act faster toward accomplishing emissions reduction, and is ready to cooperate, but puts the onus on governments to make it happen. “Despite what a lot of activists say, it is entirely legitimate to invest in oil and gas because the world demands it…..We have no choice but to invest in long-life projects.” And that is what they are doing.

A September update of global temperatures from James Hansen. The blue line that continuously represents the last 12 months shows an average that is a bit more than 1.2C above a baseline that roughly equals the preindustrial norm. No big move is expected over the balance of this year. (We still need a strong LaNina event, which has been missing for about eight years, that would cool things down for awhile and put a dip in the blue line.)
