Climate change and health: unravelling the relationship Chinese women cycle through smog and pollution over Beijing's Tiananmen Square. Photo: Oded Balilty Is climate change a serious threat to human health? Simple logic would suggest the answer is yes, a point that the Obama administration is using to build support for the President's effort to make climate change a centrepiece of his final months in office. A White House report listed deepening risks. But the bullet points convey a certainty that many scientists say does not yet exist. For example, scientists note that global travel and trade, not climate change, brought the first cases of chikungunya, a mosquito-borne tropical disease, to Florida. Temperatures may be rising, but overall deaths from heat are not, in part because the march of progress has helped people adapt — airconditioning is more ubiquitous, for example, and the treatment of heart disease, a major risk for heat-related mortality, has improved. Still, climate change is a contributing factor. Mary H. Dr C. New York Times

Katherine water restrictions to remain indefinitely as PFAS contamination fallout continues Updated 19 Apr 2018, 7:20amThu 19 Apr 2018, 7:20am A permanent solution to Katherine's water supply woes may take up to two years, as residents continue to endure water restrictions put in place when PFAS chemicals were discovered in the Top End town. The restrictions were introduced in August 2017 after the chemicals, which are linked with potentially toxic firefighting foams, were found in the town's bore water. Authorities say the town's water supply remains safe to drink, and the restrictions were designed to limit the amount of contaminated bore water used to boost supplies during the dry season. Katherine's water supply is a mix of river and bore water, and during periods of low rain — such as the dry season — more water from the town's bores must be used. Water services general manager Rob Brito told ABC Darwin the measures would be lifted when a new water source for the town was established.
