Comparing the model-simulated global warmingsignal to observations using empirical estimates of unforcednoise
A new study based on a thousand years of temperature recordssuggests global warming is progressing at the rate of a moderateemissions scenario. Researchers developed a statistical model toreplicate natural variations in climate as well as the long-termtrend. The results suggest periods of faster and slower temperaturerise in past decades are more in keeping with a ‘middle-of-the-roadscenario’, but this could change in future, the researchers say.
Causal factors for seismicity near Azle,Texas

Findings from a seismicmodel suggest that injecting and extracting high volumes of watercreated pressure changes significant enough to trigger earthquakes.A series of North Texas earthquakes over the last seven years haveall occurred in areas developed for natural gas extraction, thestudy notes, before which the last recorded tremor in the area wasin 1950.
