climate change effects

Last year was Australia’s third-hottest on record, the country’s well-respected Bureau of Meteorology says.

The BOM’s annual climate statement, released on Tuesday, said 2014 was the third-warmest year since reliable climate records began in Australia in 1910, with mean temperatures (taking into account both maximum and minimum temperatures) 0.91C above the long-term average.

A rise of two degrees will not be catastrophic, but polar bears will become extinct.

A rise of two degrees will not be catastrophic, but polar bears will become extinct. We’re halfway there now.

This is already halfway to the two-degree limit in global warming that Governments are supposedly seeking to achieve this century. Whilst change up to two degrees is expected to cause some problems, especially as regards species extinction, agriculturalists, public health, and fire danger, any warming above that level is expected to bring catastrophic climate change. And we’re already damn near 50% there.

BOM Climate Information Services assistant director Neil Plummer said 2014 was a year that included six significant warm spells or heat-waves with a notable reduction in colder weather.

The warmest year on record occurred the previous year, 2013, when the mean temperature was 1.2C above the long-term average.

“Particularly warm conditions occurred in spring 2014, which was Australia’s warmest spring on record,” Mr Plummer said. “El Nino-like effects were felt in drier and warmer conditions in much of eastern Australia during 2014.”

The World Meteorological Organisation is collating data but believes the world experienced its hottest or among its hottest years in 2014, Mr Plummer said.

The Climate Council’s Professor Will Steffen says climate change is a major factor in the near-record warmth recorded in 2014. He said 2013 and 2005 were the hottest and second-hottest years on record, and most notably 29 of the past 35 years were warmer than average.

“It is worrying that these sort of records are now being broken so regularly,” he said. “The impact of climate change on these trends is very clear. Climate change is making Australia hotter and more prone to bushfires.” (See our story on South Australia, yesterday.)

Meanwhile, Australia’s Government has scrapped the carbon trading scheme which was put in place to provide a market mechanism for reducing carbon dioxide emissions – a curious decision for a party committed to free market economics.

An astonishing and exhaustive list of anti-environment moves made by the Abbott Government appeared on precariousclimate.com back in September last year. If you were ever in any doubt that our Federal Government are a bunch climate troglodytes, check it out. It is a carefully compiled and damning document.

Whether it is cutting the money allocated to solar energy conversions to homes, (from one billion dollars to $2 million), repealing the “carbon tax”, abolishing climate change bodies, appointing climate change deniers to key Government positions both here and overseas, denying the link between climate change and bushfires, refusing to commit any climate finance for poor countries, (after Super Typhoon Haiyan devastated the Philippines and the Filipino delegation to a climate change conference called for urgent action), cutting research funding, slashing jobs in the Environment department, or hugely increasing assistance to fossil fuel industries, it is a sad, sad story.

 

Looks like the bulk of people in Africa will need to move to Canada. Hope they're ready.

Of course, as this chart (representing a ‘best case’ scenario) on possible changes to agricultural productivity shows, the effects of climate change will fall hardest on the world’s poorest countries, where drought and starvation are already endemic. That will also be of little or not interest to the Abbott Government, which has just cut, in real terms, overseas aid, to address what is largely a mythical crisis in Government spending – the same Government, remember, that has ordered nearly 60 new fighter bombers with a maximum range of 200 miles. Massive projected changes to the main agricultural areas of Australia are very worrying. With the sole exception of south-eastern Australia, (where production will likely remain unchanged, although some cropping changes may be called for), the collapse in agricultural production is up to 25%. Given that the Liberal-National Party Coalition depends on rural seats for it’s existence, this will inevitably come back to bite them. When farmers realise that “green” policies are good for their business, look out.

Let us hope it really is #onetermtony before the country gets much hotter and our world changes beyond recognition.
