Today the surface ocean is almost 30% more acidic than it was in pre-industrial times, and over the next few decades, the level of acidity of the surface ocean will continue to rise without deliberate action to reduce carbon dioxide emissions. Increasingly this will cause major problems for many marine organisms like shellfish and corals. – Scott Doney

If there’s one thing U.S. farmers can count on, it’s bad weather, and perhaps as a result, many of them don’t think humanity is to blame for the long-term shifts in weather patterns known as climate change.

We find that climate science scepticism is not limited to the scientifically illiterate, but well ensconced within this group of professional experts with scientific training – who work as leaders or advisors to management in governmental, non-governmental, and corporate organizations.

How we interpret the current slow-down in the rate of global warming depends very much on the length of the ‘leash’ in the true climate system (i.e., how large internal variability is).

Yet these and other guidelines continue to be followed despite concerns about bias, because “We like to stick within the standard of care, because when the shit hits the fan we all want to be able to say we were just doing what everyone else is doing—even if what everyone else is doing isn’t very good.” – Jeanne Lenzer

The Fifth Assessment has been a particularly turbulent period for the Intergovernmental Panel on Climate Change (IPCC). . . but the pace at which the world changes is stepping up, and we can be sure that the IPCC must adapt to these changes if it still wants to retain significance in the future.

How much effort should we exert this year as opposed to 10 years from now? How should we manage discontinuous or highly uncertain effects? What is the likelihood of a technological deus ex machina? Will climate change mean geopolitical surprise in the Arctic or from petroleum exporting nations? Are we a world filled with highly flexible innovators or low-turnover, high-cost capital stock? – Hultman, Hassenzahl, Rayner

To solve these pressing problems, there needs to be much better recognition of the importance of probability models in climate science and a more integrated view of climate modelling whereby climate prediction involves the fusion of numerical climate models and statistical models. – Stephenson et al.

Talk about perverse incentives! It appears that Chinese coolant manufacturers have been producing an excess of a harmful greenhouse chemical in order to dispose of it responsibly under the UN’s Clean Development Mechanism (CDM). – Walter Mead
