The study leveraged 3.7
Calculated vehicle fuel economy is available going back to 1923. However, the starting year of this analysis is 1966 because (1) for 1923 through 1935, fuel-economy information is available only for the entire fleet of all vehicles, and (2) from 1936 through 1965, light trucks were included with other trucks in the relevant statistics.?.

Our tool provides a simple method to integrate disparate climate and population data sources and develop preliminary per capita water availability projections at a global scale. —Esther Parish.
Bureau of Labor Statistics. The years analyzed were 2007 and 2017 (the latest available survey year). Given the sizes of the standard errors, none of the three variables of interest showed a statistically significant difference between 2007 and 2017. The data for this analysis came from ATUS—the American Time Use Survey.
The Colorado State University forecast team predicts an above-average 2010 Atlantic basin hurricane season based on the premise that El Niño conditions will dissipate by this summer and that anomalously warm tropical Atlantic sea surface temperatures will persist. The team began using a new early April statistical model in 2008.

An Independent Panel in the UK led by Lord Oxburgh, who among his other prior duties was the non-executive chairman of Shell, has cleared the University of East Anglia of any scientific impropriety and dishonesty. The Panel’s report made suggestions for improvement in some other areas.
charging infrastructure incentives, preferential charging rates), and public charging availability. The base regional unit for the study was the metropolitan statistical area (MSA). The Georgia rebate was revoked in July 2015, and a Texas incentive was limited in its availability throughout the year.
