June storms highlight impacts of rising seas, shifting storm patterns

Staff Report

Just after the Australian government announced massive cuts to the country’s science agency, researchers are warning that there’s more of a need then ever to track climate change impacts.

A series of recent storms that lashed Australia’s east coast are reminder that rising sea level presents a growing threat to coastal communities, according scientists with the University of New South Wales.

“The damage we’ve seen is a harbinger of what’s to come,” said Ian Turner, director of the Water Research Laboratory at the University of New South Wales. “Climate change is not only raising the oceans and threatening foreshores, but making our coastlines much more vulnerable to storm damage. What are king high tides today will be the norm within decades.” Continue reading “Australian researchers call for more coastal monitoring in the face of expected climate change impacts”

Climate: Study links deadly 2010-2011 Australia floods with long-term ocean warming

‘Take action to forestall global warming …’

Staff Report

Deadly floods that swept across Australia in 2010 and 2011 were at least partly fueled by long-term warming in the Indian and Pacific oceans, according to a new study that highlights some of threats posed by human-caused climate change.

The research, published in Geophysical Research Letters, shows that ocean warming can have profound effects on atmospheric circulation, delivering huge amounts of moisture to land areas under certain conditions.

Study sees huge climate threat to tropical cloud forests

FRISCO — Scientists have long warned that mountain ecosystems are especially vulnerable to climate change, because as temperatures warm, species adapted to living atop mountains just won’t have anywhere to go.

A new study by Australian scientists appears to confirm those fears, concluding that the cloud forests in tropical forests are the most at risk. Many tropical, mountaintop plants won’t survive global warming, even under the best-case climate scenario. Continue reading “Study sees huge climate threat to tropical cloud forests”

Report: Australia’s humpback whales are thriving

FRISCO — While many Australian animal species are being pushed toward extinction, humpback whales off both the country’s east and west coasts are making a strong comeback from the whaling era.

Recent research suggests humpback populations are growing at about 10 percent annually, and that populations have recovered to between 60 and 90 percent of pre-whaling numbers, according to a new study published in the journal Marine Policy.

Study: Cultural shift and centralized planning helped Melbourne adapt to Australia’s Millennium Drought

FRISCO — Drought-prone cities and regions around the world can look to Melbourne, Australia to get an idea of what it takes to tackle water shortages during extended dry spells — and to prepare for future droughts, which are projected to become more frequent in some regions as global warming intensifies.

As the worst drought in Australia’s history took hold during the late 1990s, the city’s 4.3 million residents were able to cut their daily water use by half, to just 41 gallons per per person, according to a new study.

Staff Report

FRISCO — After a 40-year span when the Great Barrier Reef lost half its coral cover, and with global warming looming for the future, Australian scientists say fundamental changes are needed to protect the reef.

Better policies focusing on science, protection and conservation are the key, a team of leading researchers wrote this week in the journal Nature Climate Change, arguing that all the stressors on the Reef need to be reduced for it to recover.

Geothermal exploration leads to unexpected discovery

Staff Report

FRISCO — Scientists exploring deep underground for geothermal resources in Australia got more than they bargained for when they found signs of an ancient 400-kilometer-wide impact zone from a huge meteorite that broke in two moments before it slammed into the Earth.

The crater from the impact millions of years ago has long disappeared. But a team of geophysicists has found the twin scars of the impacts — the largest impact zone ever found on Earth — hidden deep in the earth’s crust. Continue reading “Australian scientists find largest-ever meteor impact zone”
