Atmospheric CO2 update.  We are just two or three weeks away from the annual seasonal peak, which last year came in a bit below 412 ppm.  At the end of April we are already past 414, with another quarter or half PPM to go, for a pace of annual increase that is higher than normal for this century and very disappointing.  For the full story, scroll down to the lower chart and also check out the other links on this website.  When is the urgently needed downturn going to begin?

Coral reefs move toward the poles in order to avoid warmer ocean water (Newsweek).  A new study has taken a close look at how they have done so in the past and are doing the same thing again today, with difficulty.  “On the century scale, our models show that if we don’t take action to reduce global warming, we could lose most of the suitable habitats in equatorial and tropical regions…..the rate of change we see today is quite unprecedented in geological record.”

In the US, the Southwest is getting hammered by rising temperatures (Arizona Public Media).  “Tucson….has 25 more days above 100 degrees than it did in 1970.

A new book offers a complete primer about drought (Phys.org).  This post features an interview with the author, a foremost expert in the science and history of drought.  “All these changes we’re observing are completely in line with what the models are telling us should happen. We expect these impacts to get even worse with continued warming in the future.”

Deforestation causes a significant increase in nearby land surface temperatures, with a direct effect on certain species of animals (Yale Climate Connections).   This story is based on several studies and interviews with their authors.  It deals with serious climatic effects of deforestation that have nothing to do with carbon dioxide, but are of similar nature and more immediate to appear on local scenes, especially in the tropics.  “Climate change is really bad and deforestation at a local scale makes it even worse…..The lizards told me that.”

Madagascar is rapidly losing its unique wildlife (Science Daily).  While not specifically about climate change, this is the story of an island that represents a paradigm and advance warning for the entire planet.  Through reckless behavior, one new species has broken all the rules of sustainable ecology that were in effect for tens to hundreds of millions of years.
