One graph I caught up with this week has convinced me that climate change mitigation by supressing carbon dioxide emissions is a busted flush that history will look back on with great ridicule, even if the worst of the climate alarmist predictions come to pass.

Global temperatures are adjusted to account for the effects of station moves, instrument changes, time of observation (TOBs) changes, and other factors (referred to as inhomogenities) that cause localized non-climatic biases in the instrumental record.

Christopher Booker’s recent piece along with a few others have once again raised the issue of adjustments to various temperature series, including those made by Berkeley Earth. And now Booker has double-downed accusing people of fraud and Anthony Watts previously insinuated that adjustments are somehow criminal .

A recent posting presented taxonomy of potential policy perspectives around climate/energy policy. The ensuing comments brought home the unfortunate recognition that energy providers have not advocated specific actions and preferred directions for climate/energy policy. I think they have a good story. Why aren’t they telling it?

Satellite data for the period surrounding the Mt Pinatubo eruption in 1991 provide a means of estimating the scale of the volcanic forcing in the tropics. A simple relaxation model is used to examine how temporal evolution of the climate response will differ from the that of the radiative forcing.

Climate psychologists have for years now puzzled over public inaction on climate change and also what makes skeptics tick (or sick), apparently making little progress on these issues.

All this talk about climate change has misled us collectively. It has made us search for a mega solution to a mega problem: it has created the impression that if we solve the problem of climate change, all other problems would also be solved. This is not the case. – Eija-Riitta Korhola

Perhaps my experience in studying the Earth, initially with few restrictions and later with increasingly sophisticated interaction with government sponsors and various planning committees, will provide a perspective on this great transition from science being primarily an intellectual pastime of private persons to its present status as a major contributor to the quality of human life and the prosperity of nations. – Charles Keeling

The Atlanta Journal-Constitution asked a dozen of the state’s top elected officials and the director of the agency tasked with the state’s environment whether they believe the globe is warming, and whether they think pollution caused by human activity is a cause.
