«[Howarth et al.'s] analysis is seriously flawed in that they significantly overestimate the fugitive emissions associated with unconventional gas extraction, undervalue the contribution of «green technologies» to reducing those emissions to a level approaching that of conventional gas, base their comparison between gas and coal on heat rather than electricity generation (almost the sole use of coal), and assume a time interval over which to compute the relative climate impact of gas compared to coal that does not capture the contrast between the long residence time of CO2 and the short residence time of methane in the atmosphere.»

Two studies have analysed cost effectiveness of CBT for severe health anxiety delivered in a conventional face - to - face format compared with treatment as usual using data from randomised controlled trials.8, 9 In the first study, it was found that CBT but not the control condition reduced consumption of primary and secondary healthcare contacts, but total costs were unchanged in both conditions.8 In the second study, a large - scale randomised trial, the health economic analyses showed that there were no significant differences between the two treatment conditions.9 In both of the above studies, CBT was superior in reducing health anxiety symptoms compared with treatment as usual, which means that as costs were similar across groups, CBT is likely to be the more cost - effective treatment option.
