Near-Term Human Extincton: Making the Case

radioecoshock — Sun, 21 Sep 2014 22:49:31 +0000

Let me ask you: Do you have days when you feel we are doomed as a species? That's every day, for our next guest.

When a successful Professor of Natural Resources, Ecology, and Evolutionary Biology left the University of Arizona, for his mud hut retreat, he probably didn't intend to stir up the world. But that's just what Guy McPherson has done. He's becoming a voice for the worst fears of many people. In fact, McPherson says climate change has gone so far, so fast, humans will become extinct before 2050.

Biodiversity decline from climate change affects huge range of common species

takver — Sat, 18 May 2013 12:56:18 +0000

While much scientific and public attention has focussed on the many species endangered or on the brink of extinction like Carnaby's cockatoo, the impacts of climate change on species biodiversity are much larger. A landmark study looking at nearly 50,000 common species with widespread ranges has determined that half of these animals and two thirds of the examined plant species will lose more than half their range in the next 70 years, by 2080, if nothing is done to slow down the rate of global warming through cutting carbon emissions. We are truly in the middle of a biodiversity crisis with habitat loss and climate change causing the 6th mass extinction

Tasmanian bush fires sign of world to come

The image of kids in the water clinging to a dock, under a fire-red sky, captured the situation. The great Australian heat wave of 2013 also struck the southern-most part of the country, the island of Tasmania. Maybe this is the future anywhere trees grow, as global warming heats the planet.

Professor David Bowman is at the University of Tasmania in Hobart, teaching and researching Forest Ecology. He's a published expert on fire in the earth system.

Climate change implications of new study on methane emissions in coal seam gas field

takver — Fri, 16 Nov 2012 01:46:02 +0000

Coal seam gas has been touted as a green transitional fuel, far less polluting than coal, but a new study implies it may not be as green or climate friendly as the industry makes out. It hinges on the level of fugitive emissions produced in development and production of a gas field. A study by two scientists from Southern Cross University based in Lismore, northern NSW, detected much higher levels of the strong greenhouse gas methane around the Tara gas field on the Darling Downs of Queensland west of Brisbane.

Action: Getup! have started a Dirtier than Coal? campaign calling on Federal Climate Change Minister Greg Combet to commission urgent research into the climate impacts of coal seam gas, and to make sure that CSG companies start accounting, and paying, for fugitive emissions.

Global warming intensifying global water cycle by double current climate model projections

takver — Sat, 28 Apr 2012 09:01:33 +0000

New research into ocean salinity levels has revealed a strong global water cycle intensification during the period of 1950 to 2000. The researchers report the rate of change in the global water cycle is double the rate projected by current-generation climate models. The study found "robust evidence of an intensified global water cycle at a rate of about eight per cent per degree of surface warming," said study co-author Dr Durack, a post-doctoral fellow at the Lawrence Livermore National Laboratory in the US.

Climate down in Durban

Diplomats from all over the world are returning home after a hard-won agreement in Durban, South Africa.

They agreed to do nothing to save our climate from disaster.

Our governments will talk until 2015, and then maybe do something serious about greenhouse gas emissions in 2020. By then, as Radio Ecoshock listeners know, we will be committed to at least 3 and a half degrees Centigrade hotter world in 2100, than our ancestors knew in 1750. It will only get hotter after that.

Fracking Gas = Climate Crash

For years, governments, industry, and TV ads told us natural gas is the safe bridge fuel while we move away from dirty coal and oil.

Cornell University scientist Robert Howarth wondered "Is that true?". When Howarth found no science to back up big claims for the gas industry, he and a team from Cornell went to work.

Temperature study funded by climate sceptics confirms rate of global warming

takver — Fri, 21 Oct 2011 16:09:39 +0000

"We are seeing substantial global warming" declares new scientific work from an independent group of researchers called the Berkeley Earth Surface Temperature Study. The research team is at least partially funded by the Koch Brothers who fund several climate denial groups. The team was setup to identify flaws in the climate science of global average temperature trends, but has confirmed the analysis undertaken by NASA, NOAA and the Hadley Climate Centre in the UK that about 1 degree Celsius of global warming has occurred since 1950.

Logging of Victorian mountain ash forests increases bushfire risk

takver — Tue, 11 Oct 2011 09:31:05 +0000

New scientific research published in September 2011 highlights that logging in Victoria’s mountain ash forests is increasing the risk of catastrophic wildfires. The cycling of logging and wildfire is creating a landscape trap where the wet forest ecosystem is being permanently converted to a new landscape replaced by other species, particularly wattle, increasing the frequency and intensity of bushfire risk.

"These changes will significantly impair ecological functions like carbon storage, water production and biodiversity conservation," said Professor Lindenmayer. "This is historically unprecedented and is beginning to dominate the mountain ash landscapes we see today."
