This is a few weeks old, but I haven’t seen much mention in the blogosphere. Perhaps I missed it.
A significant study by Betts et al. of the Hadley Centre in the UK examines the observational record for biotic-CO2 feedback on hydrology. Plant physiology is substantially affected by the increases in CO2, directly, without any reference to climate change. [more]
Trenberth and Dai in GRL argue that injection of aerosol into the upper atmosphere reduces the vigor of the hydrological cycle, and thus is not a good compensation for greenhouse gas forcing. Even the abstract is behind the firewall! (That seems a bit counterproductive on any model of scientific publishing.) Here is the abstract:
Effects of Mount Pinatubo volcanic eruption on the hydrological cycle as an analog of geoengineering
I think there should be a global index of how anomalous the global weather is at any given moment. It’s not obvious what the right metric would be. Because everything is more or less coupled to everything else, anomalous weather in one place should be accompanied by anomalous weather elsewhere. [more]
Here’s a little more detail on our atypical summer from our local daily news source, the Statesman. (Note, if you are visiting from the Future, welcome. Sorry that these stories may already have expired. I hope you are comfortably cool and dry in the Future.)
18 inches of rain in 24 hours, yesterday, just upriver from us at Marble Falls TX. The flood control people (the LCRA = “Lower Colorado River Authority”) are going bonkers trying to smooth this event out and parcel out minimal flood damage. More rain is expected in the Colorado basin this week. [more]
