Masters says his “conservative” judgment is that Arctic will be ice-free in summers just a decade from now.2012: Warmest Year for the U.S. … and Warm Too for the World | The Yale Forum on Climate Change & The Media
Temperature data in the United States are imperfect. Temperature is measured at weather stations not intended to create long-term climate records. Over the past century these stations have been relocated, for instance from building rooftops to airports and wastewater treatment plants in the 1940s. The instruments themselves have changed, going from liquid-in-glass thermometers to electronic sensors in the 1980s. The time of day at which the temperatures were measured has changed, from evening pre-1970 to morning. And the environment around sensors has changed as cities have grown and more land has been developed.Climate Change in The West Wing? | The Yale Forum on Climate Change & The Media
Lessons for Obama from The West WingTHE HOCKEY SCHTICK: New paper notes long-term climate change may be 'inherently unpredictable'
A paper published today in the Journal of the Atmospheric Sciences reveals the abject failure of climate models to project either the transient or long-term ["equilibrium"] climate change from greenhouse gases. The paper notes, "The Equilibrium Climate Sensitivity (ECS) has a large uncertainty among models participating in the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) and has recently been presented as “inherently unpredictable”. One way to circumvent this problem is to consider the Transient Climate Response (TCR)[short-term response to greenhouse gases]. However, the TCR among AR4 models also differ by more than a factor of 2." Furthermore, the authors find that the projections vary by 30% even within the same model with the same equilibrium climate sensitivity."
