Warming temperatures will cause increased drought and sea-level rises in Australia and New Zealand by 2030 and threaten ecologically rich sites such as the Great Barrier Reef, according to excerpts from a new scientific report released Tuesday.
BANGKOK, Thailand -- Warming temperatures will cause increased drought and sea-level rises in Australia and New Zealand by 2030 and threaten ecologically rich sites such as the Great Barrier Reef, according to excerpts from a new scientific report released Tuesday.
The South Pacific Islands, meanwhile, will be swamped by sea level rises as well as increased frequency of cyclones, according to the latest report from the Intergovernmental Panel on Climate Change.
Island economies also will suffer as warming waters damage coral reefs and hurt the fishing industries, the report said.
A summary of the full, 1,572-page document written and reviewed by 441 scientists was released Friday. This document, the second of four reports, tries to explain how global warming is changing life on Earth.
Further details were being unveiled Tuesday in a series of regional news conferences around the world.
For Australians and New Zealanders, the warming temperatures will be felt mostly through increasingly extreme weather events.
"Heat waves and fires are virtually certain to increase in intensity and frequency," Kevin Hennessy, the coordinating lead author on the chapter for Australia and New Zealand, said in a statement.
"Floods, landslides, droughts and storm surges are very likely to become more frequent and intense and frosts are very likely to become less frequent," he said.
The rising temperatures, according the report, also will lead to a loss of a quarter of alpine ice mass in New Zealand, drops in agriculture production in southern and eastern Australia and eastern New Zealand, as well as the spread of tropical diseases such as dengue fever.
Sea level rises in the South Pacific islands "are likely to endure exacerbate inundation, storm surge, erosion, and other coastal hazards, thus threatening vital infrastructure, settlements and facilities that support the livelihood of island communities," according to the report.
Penehuro Lefale, one of the lead authors on the small island chapter, said in a statement that the warming temperatures also will hurt sectors as wide-ranging as tourism, agriculture and fisheries on many island nations.
"Climate change is likely to heavily impact coral reefs, fisheries and other marine-based resources of small islands of the Pacific," he said. "There is likely to be a decline in the total tuna stocks and a migration of these stocks westwards, both of which will lead to changes in the catch in different islands."
