A CO2-warming atmospheric scenario, whereby increased concentrations of 'greenhouse' gases result in warmer temperatures that either melt near-polar ice or cause thermal expansion of ocean waters, thus leading to increased sea-levels and exacerbated coastal erosion, assumes fundamental but unproven cause-and-effect relationships. General circulation models have reinforced claims of an accelerated warming and indirectly given support to the complete scenario, but ignore the point that global climate and not just air temperatures have changed over the past century. Indeed, it is difficult to prove that air temperatures have warmed naturally outside of urban centres over this period. To attribute recent temperature …

Headache is a common symptom in primary care about which surprisingly little is known. Over a 14-month period 3847 patients making 4940 consecutive visits for headache to 38 primary care practices in the USA and Canada were studied. The clinical characteristics of patients, as well as the diagnostic and therapeutic strategies employed by their doctors, were examined. Visits for headache represented 1.5% of all visits during this period. Most patients (72.0%) made only one visit, and nearly half of the headaches reported were new. Only a small number of patients (3.0%) received a computerized tomographic scan; other investigations were used …
