CANBERRA, March 20 (Xinhua) -- Temperature in northern Australia is tipped to soar over the next 12 years, with Darwin expected to receive 132 days of 35-centigrade-plus heat by 2030, up from the current figure of 22 days.

And by 2070, the Northern Territory capital could swelter in temperatures above 35 centigrade for 275 days a year, a 1,250 percent increase on the current figure.

The warning is delivered from an Australian Institute report, based on data from the Commonwealth Scientific and Industrial Research Organisation and the Bureau of Meteorology, released on Tuesday.

It says Darwin residents and NT industries are facing a dramatic increase in the number of days where heat stress reaches "extremely dangerous" levels.

Mark Ogge, principal advisor at The Australia Institute and co-author of the report, told Xinhua News on Tuesday that the projected heat would have a "devastating effect" upon tourism and residents' liveability.

"You won't be able to spend time outdoors enjoying the territory and lifestyle will be severely constrained," he said.

"Elderly people and small children the most impacted, but a temperature increase like this impact everybody. It can cause death even among healthy people.

"The temperatures will slash productivity in the construction industry and could have really serious health impacts upon workers."

The number of days over 35 centigrade between 1911 and 1940 was recorded at 5.6 a year, which has increased to an average of 22.2 days since 2013.

Without climate change action, the report suggests the Darwin community and it key industries face a major struggle, and humidity will add to the risk.

"When combined with Darwin's humidity, many days of the year will have extremely dangerous heat stress risk," said report co-author, Liz Hanna.

"If this happens, the risk of death is possible after a short period of exposure at rest, and particularly in combination with even relatively low levels of physical exertion."
