Strange Sounds – June 4, 2018
This year’s forecast is about average and much more subdued than last summer’s hyperactive season turned out to be, partly due to cooler ocean temperatures in the tropical Atlantic, as well as a nascent El Niño pattern. But that doesn’t mean an individual storm won’t blow up to exceptional strength, as Andrew did before striking Florida in 1992, an otherwise relatively quiet year.
Heat trapped by the increasing concentration of greenhouse gases in the atmosphere is raising the chances of that happening, said Penn State climate scientist Michael Mann.
A new review of global data on hurricanes shows that since 1980, the number of storms with winds stronger than 200 kilometers per hour (124 mph, or a strong Category 3) have doubled, and those with winds stronger than 250 kilometers per hour (155 mph) have tripled.
“The current intensity scale doesn’t capture the fact that a 10 mph increase in sustained wind speeds ups the damage potential by 20 percent,” Mann said. “That’s not a subtle effect. It’s one that we can see.” Based on the spacing of Categories 1-5, there should be a Category 6 approaching peak winds of 190 mph, he said.

Australia sweltered through its third-hottest year on record in 2017 despite the lack of a warming El Nino weather phenomenon, official figures showed Wednesday.
Seven of the vast continent’s 10 warmest years have occurred since 2005, with only 2011 cooler than average, the Bureau of Meteorology (BOM) said in its annual climate statement.
“Despite the lack of an El Nino — which is normally associated with our hottest years — 2017 was still characterised by very warm temperatures,” the weather bureau’s climate monitoring chief Karl Braganza said in a statement.
“Both day- and night-time temperatures were warmer than average, particularly maximum temperatures, which were the second-warmest on record.”
The data came ahead of the release of global mean temperatures by the World Meteorological Organisation, with BOM projecting that 2017 was one of the world’s three warmest years on record — and the hottest without an El Nino.

In Somalia, some 5.5 million people are in desperate need of humanitarian assistance to survive the next six months, UN Secretary General António Guterres said earlier this month.
Across the Horn of Africa, millions have been hit by a severe drought brought on by the El Nino climate cycle, but Somalia is seeing the worst effects of the drought.
Millions are moving to camps in search of for food and water to survive.

The El Niño phenomenon has compounded the woes of drought-stricken southern Madagascar, where 80% of the rural population is suffering from food insecurity. EurActiv France reports.
It has not rained in Tsihombe since January, Reho Ziry remembered as we crossed the bridge over the dry bed of the Mananbovo river. Since then, the sun has baked the arid land in this district of the southern Madagascar’s Androy region, drying out watercourses and crops.
