surprise, surprise!

Carbon offsets. The way this works is that you pay someone else to take action – by planting trees or investing in renewable energy sources – that will reduce greenhouse gases. That action acts as a proxy for your own emission cuts.

However, research by the University of NSW found many of the carbon certificates issued don’t represent additional cuts in emissions. In other words, some firms are being rewarded for doing things they would have done regardless of the financial incentive offered by the scheme.

For example, government agency, Forests NSW, generates certificates from its forests and sells the certificates to offset companies who then sell them to the public. But Forest NSW hasn’t planted any additional trees.

ban trees, plants and soil!

Scientists at Bristol University in Britain say a recent surge in carbon dioxide levels in the atmosphere is due to green house gas escaping from trees, plants and soils.

Global warming was making vegetation less able to absorb carbon pumped out by humans, such a shift could worsen predictions of the UN’s panel on Climate Change, which has warned there is less than a decade in which to tackle emissions to avoid the worst effects of global warming.

Measurements of carbon dioxide in air samples show unusually high levels in four of the past five years.

help the helmeted honeyeater!

Drought could be threatening Victoria’s state bird emblem, the endangered helmeted honeyeater, with research showing a “significant correlation” between declining rainfall and reduced egg laying.

Bruce Quin, the Department of Sustainability and Environment’s field ornithologist for the helmeted honeyeater, agreed the future of the Victorian bird looked grim. He said the number of breeding pairs at Yellingbo — 50 kilometres east of Melbourne — had fallen to a record low of 11 in the past breeding season, compared with 15 in 1989-90.

over the top

Australia needs a new “industrial revolution” to come up with an effective strategy against global warming, the Australian of the Year, Tim Flannery, will tell one of the country’s largest unions this week.

He will tell members of the Autralian Workers Union that climate change has occurred so quickly that the Government needs to think of it as like going to war.

While stopping short of endorsing either party, Professor Falannery’s speech tomorrow says: “We need a government willing to truly lead on the issue, one willing to get on a war footing, and willing to dip into our surplus to help fund a new industrial revolution that will give Australia’s industry and environment a new lease of life.”

sounds greenish to me

lightbulbThe inefficient standard light bulb could be phased out within three years to save up to 800,000 tonnes of greenhouse gas emissions. The federal Environment Minister, Malcolm Turnbull, is expected today to announce a commitment to phase out incandescent light bulbs by 2009-10, a world first by a national government.

Colin Goldman, the head of Nelson Industries, a lighting importer, supported the move. Mr Goldman said compact fluorescent bulbs were available that emitted a range of light. “You can get warm white, which is a yellowish light, or natural, which is white, or day-light, which is more blueish.”

a wake up call

The Intergovernmental Panel on Climate Change projects significant disruption to coffee production as the planet warms.

While some places might become more suitable to grow coffee as the planet warms, the drafts say that in many cases suitable growing land will contract significantly with 2 to 2.5 degrees of warming. An overall decline in good coffee growing areas by 2050 was found in all countries studied.

damselfish in distress!

A study from scientists at James Cook University shows increased carbon dioxide levels impaired the senses of spiny damselfish, which live in the Great Barrier Reef.

Fish exposed to higher carbon dioxide levels – which are expected to increase in the oceans for several decades – showed impaired cognitive function, learning difficulties, slowed visual capacity and altered sense of smell and sound.

The damselfish also lose their ability to recognise threats, including the smells of predators when exposed to higher levels of carbon dioxide – and will even become attracted to them instead. Sydney Morning Herald, 6 Oct 2014

more tipping points

An average global temperature rise of 7.2F (4C), considered a dangerous tipping point, could happen by 2060, causing droughts around the world, sea level rises and the collapse of important ecosystems.

The Arctic could see an increase in temperatures of 28.8F (16C), while parts of sub Saharan Africa and North America would be devastated by an increase in temperature of up to 18F (10C).

Britain’s temperature would rise by the average 7.2F (4C) which would mean Mediterranean summers and an extended growing season for new crops like olives, vines and apricots.

However deaths from heat waves will increase, droughts and floods would become more common, diseases like malaria may spread to Britain and climate change refugees from across the world are likely to head to the country.

Dr Richard Betts, Head of Climate Impacts at the Met Office Hadley Centre, said the new study showed how important it was to try and reduce emissions.

like cats on a hot tin roof

When Kristina Vesk started working at the Cat Protection Society of NSW in 2006, she rarely saw kittens in winter. Now warmer weather means cats are breeding all year round, increasing the numbers of unwanted kittens and the threat to native wildlife from strays and feral cats.

Ms Vesk, the society’s chief executive, said there used to be weeks from June to September when the shelter saw very few, if any, kittens. But with the climate changing and temperatures rising, it seems cats are increasingly on heat.

“For the past three years, I don’t think we’ve experienced a full week at any time of year where we don’t have at least a couple of kittens in our care,” Ms Vesk said. “Kitten ‘season’ has grown longer and longer as we keep having … enough warm and sunny days in winter that make cats think it’s a good time to start breeding.”

dog day afternoons

Leading pet behaviourists told The Independent that the number of depressed and unsettled dogs they have seen in recent months is unprecedented. And they suggested that the spate of wet winters could be at the root of the problem, as owners cut down on the daily walks that are crucial to keeping dogs’ spirits up.

“I’ve been working with dogs for more than 20 years and I can’t remember a time when they’ve been this bored. I tend to see boredom in bursts but I’m seeing it chronically this winter,” said Carolyn Menteith, a dog behaviourist who was named Britain’s Instructor of the Year in 2015.

She – like many scientists and meteorologists – puts this down to climate change and expects to see more bored dogs in the future as global warming unleashes increasingly frequent and intense bouts of winter rainfall.

stable shoreline slips away

“More ominous tipping points loom. West Antarctic and Greenland ice sheets are vulnerable to even small additional warming. These two-mile-thick behemoths respond slowly at first, but if disintegration gets well under way, it will become unstoppable. Debate among scientists is only about how much sea level would rise by a given date.

In my opinion, if emissions follow a business-as-usual scenario, sea level rise of at least two meters is likely within a century. Hundreds of millions of people would become refugees, and no stable shoreline would be reestablished in any time frame that humanity can conceive.”

Saved, but the party’s still over

“According to climate scientist James Hansen, we are never going to see another ice age, ever. When the ice melts it will not be replaced. Ice extent will fluctuate from year to year, and some climate change deniers will selectively point to recovery years, but there is only a downward escalator. Which means, unless dangerous climate change is addressed, for some of us today, and many more tomorrow, the party will definitely be over.”The Conversation, 20 Sep 2013

Comment – adapting to a change of climate

The Australian federal government has proposed a restructure of its science agency, the CSIRO, to place more emphasis on practical measures rather than environmental research.

But the proposal has met resistance including University of Melbourne earth scientist Kevin Walsh who said: “It is incorrect to say that the climate change science problem is solved, and now all we need to do is figure out what to do about it. No working climate scientist believes that.”
The Australian, 5 Feb 2016

It seems that if you ask questions about climate change you’re told that the science is settled.

But if you want to trim the budget of a government science agency you suddenly find that the science isn’t settled.

waking the giant

giantThe disappearing ice, sea-level rise and floods already forecast for the 21st century are inevitable as the earth warms and weather patterns change – and they will shift the weight on the planet.

University College London’s Bill McGuire, professor emeritus of Geophysical and Climate Hazards, calls this process “waking the giant” – something that can be done with just a few gigatonnes of water in the right – or wrong – place.

sounds more like a religion everyday

In a project they hope to take nationwide at a cost of up to $2 million a year, Australia’s main environment groups will next week start door-knocking in Sydney’s east to talk about what predicted climate changes could mean for beaches and parks, health and hip pockets.

Supported by Greenpeace, WWF Australia, Climate Action Network Australia, the Nature Conservation Council of NSW and Environment Victoria, the Power to Change campaign will also include mail drops, street stalls and public meetings.

These reports aren’t aimed at scaring people by making outlandish predictions, said the campaign’s founder, Dave West. Rather, we are trying to paint the best picture of how climate change will affect people’s lives … how bad it will be depends on how fast we act and how deep we can cut our greenhouse gas emissions.

tipping point passed

“Today I testified to Congress about global warming, 20 years after my June 23, 1988 testimony, which alerted the public that global warming was underway. There are striking similarities between then and now, but one big difference. The difference is that now we have used up all slack in the schedule for actions needed to defuse the global warming time bomb.

The next president and Congress must define a course next year in which the United States exerts leadership commensurate with our responsibility for the present dangerous situation.

Otherwise it will become impractical to constrain atmospheric carbon dioxide, the greenhouse gas produced in burning fossil fuels, to a level that prevents the climate system from passing tipping points that lead to disastrous climate changes that spiral dynamically out of humanity’s control.”

staring down barrel

pig_in_barrel“And how far will it go? Climate forecasts have long noted that every increase in global temperature heightens the odds of runaway global warming, beyond any human control. Continued overheating could unlock more methane from Arctic regions beyond Siberia.

It could cripple the vital ability of plants and oceans to absorb CO2 from the atmosphere, turning them into gushing sources of new CO2 that accelerate the superheating even further. The ice caps that help cool the Earth by reflecting sunlight into space could vanish. In the end, the relentless rise in temperature could induce a cataclysmic venting of billions of tons of methane from the oceans.

It seems likely that we are staring down the barrel of the full force, worst-case scenarios studied by the IPCC and other research organizations”

deluge!

Boston and Atlantic City, New Jersey could experience the equivalent of a once-in-100-years flood as frequently as every year or two, according to the report by the Union of Concerned Scientists and a team of more than 50 researchers and economists.

Only western Maine would retain a reliable ski season by the end of the century if emissions are at the higher end of the scientists’ projections, the report said. Peter Frumhoff, director of science and policy at the scientists’ group and chair of the research team that worked on the report.

Could global warming cause surge in kidney stones? Hot weather increases risk of painful condition, experts claim.

Researchers at The Children’s Hospital of Philadelphia examined 60,000 patients in several cities across the U.S., with varying climates, discovering a link between hot days and kidney stones.

Lead researcher and urologist, Gregory Tasian, said: ‘We found that as daily temperatures rise, there is a rapid increase in the probability of patients presenting over the next 20 days with kidney stones.

As a result, tourists would soon be forced to shift further north for summer holidays, to regions such as northern France, the Baltic and the UK.
