A major new study published Thursday on the effectiveness of climate measures such as taxes or subsidies in reducing greenhouse gases has found stand-alone measures fail to make a big difference. Published in the journal Science, the study examined 25 years of public policies in 41 countries across six continents. It concluded that out of the 1,500 policies analyzed in sectors including energy, transport and construction, "only 63 cases of successful climate policies, each leading to average emission reductions of 19 percent, were identified."

Maduro asked the court earlier this month to weigh in on the election, in which he claims he beat Edmundo Gonzalez Urrutia.
