southern fish given the elbow!

crowded_fishClimate change is expected to considerably change Australia’s marine environment with fish stocks moving further south as ocean temperatures rise, a new CSIRO report warns.

Report co-author Dr Alistair Hobday said that global warming could have positive and negative impacts on fish numbers around the country. “The southeast of Australia will experience ocean warming that will allow some fish species to move south into temperate waters,” he said.

“That could have, for example, a positive impact for recreational tuna fishermen. The negative impact would be that southern fish species are pushed too far south, meaning their numbers will decline because they will not have a suitable habitat to survive in.”

never smile at a ….

Rising temperatures could force the birth of more female crocodiles and fewer males, an expert said today. The scenario could cause some croc populations to disappear.

Crocodile gender is determined by temperature during incubation. Nest temperatures of 89.6 to 91.4 degrees Fahrenheit (32-33 Celsius) result in males. Anything warmer or cooler produces females.

Temperatures typically vary from the top of a nest to the bottom, producing both genders.

poisoned fish

Known as ciguatera fish poisoning, the illness has been mostly tropical.

The higher risk tends to be the predatory species that eat herbivorous fish, said Christopher Bolsh, senior lecturer at the University of Tasmania’s Institute for Marine & Antarctic Studies.

“Ciguatera is probably the most serious human seafood poisoning issue.”

“Again, climate change appears to be playing a role. Microalgae thrive as waters warm but also as corals die off – an outcome triggered by more intense storms but also from coral bleaching,” Dr Murray, from the University of Technology, Sydney, said.

how do you like them …

Global warming is causing apples to lose some of their crunch, but it is also making them sweeter, a study has said.

Analysing data gathered from 1970 to 2010 at two orchards in Japan, a research team said on Thursday there was clear evidence that climate change was having an effect on apple taste and texture.

“All such changes may have resulted from earlier blooming and higher temperatures during growth season”, they wrote in the journal Nature Scientific Reports.

glaciers head for the hills!

Climbers and officials in Nepal are worried that global warming is making the glacial environment unsafe for humans in the Himalayas. They say human settlements and activities such as mountaineering are threatened by glaciers retreating and glacial lakes growing both in number and size.

Global warming rates in different parts of the country vary, says Saraju Baidya, a meteorologist at the department, which has been collecting data from around the country for 30 years. He and his colleagues say climate change has caused glaciers in the northern Himalayas to retreat at a rate never seen before, posing the threat of ‘glacial lake outburst floods’

all is now explained!

In her book This Changes Everything, Naomi Klein points to a study by sociologists Aaron McCright and Riley Dunlap that finds that white males are six times as likely to believe climate change “will never happen” as the rest of the adults surveyed.

They attribute this finding to the fact that white males are disproportionately threatened by the potentially disruptive effects that climate change policy will have on the kind of power they wield in society.

So in order to maintain their social rank, people who have more to lose are more likely to deny information that would force them to change their worldview.

2006 to 2015: we’re halfway there!

“Already in the year 2025 the conditions for winter sports in the Fichtel Mountains will develop negatively, especially with regards to ‘natural’ snow conditions and for so-called snow-making potential. A financially viable ski business operation after about the year 2025 appears under these conditions to be extremely improbable”.Andreas Matzarakis, University of Freiburg Meteorological Institute, 26 July 2006

“The Fichtel Mountains are not just a wonderful stomping ground for snow shoe tours; they are also a paradise for cross-country skiers. Around 100 kilometres of ski runs in both the classic and skating styles, and in all difficulty levels, are marked each day in the north Bavarian Central German Uplands.”Fichtel Mountains: Franconia’s snow paradise, Holidays in Bavaria website 2015

all the proof you need

Sunflowers are normally associated with warmer climates and scientists believe that global warming is responsible for allowing them to grow successfully in the northern isles. They were grown by Richard Herdman, an Orkney farmer, who scattered the seeds over two and a half acres of his dairy farm in the west Mainland area.

Ruth Dawkins, of the Stop Climate Chaos group, said the success of the sun-loving yellow flowers on Orkney was a sign of global warming.

fish going south

The wild barramundi may be forced to flee further south due to warmer waters, according to new research by Queensland government climate scientists.

Natural Resources Minister Craig Wallace said researchers from the Queensland Climate Change Centre of Excellence had found projected rises in sea water temperatures due to global warming may decrease the numbers of fish in the state.

feeling blue

Frustrated green scientists and environmental activists may be at a high risk of depression.

Susie Burke, a senior psychologist with the Australian Psychological Society, has done extensive work on the mental impact of climate change.

“We can be very sure that many people in the field of climate change are distressed – highly distressed – and it can have a significant psychosocial impact on their well-being,” Burke said.

“If you’re feeling stress, anger, guilt, anxiousness or hopelessness, it has effects on your life. Depression becomes a real risk.”

watch out for falling satellites

Air in the atmosphere’s outermost layer is very thin, but air molecules still create drag that slows down satellites, requiring engineers to periodically boost them back into their proper orbits. But the amount of carbon dioxide up there is increasing. With more carbon dioxide up there, more cooling occurs, causing the air to settle. So the atmosphere is less dense and creates less drag.Live Science, 16 Aug 2011

the frontiers of climate science

Science News: In a fifteen-page article due to be published in next month’s Nature, an author with no previous scientific background argues that he has proven a link between climate change and the disappointing size of his penis.

Philip Campbell, editor-in-chief of Nature Publishing Group, has defended the decision to publish the piece without it being subjected to peer-review by the scientific community:

“Sean Johnson’s ground-breaking work must be read by everyone. I appreciate that the measurement, causes, and even the existence of climate change are divisive issues. Yet the idea that man-made global warming may explain a less-than satisfactory penis-size is something that can unite scientists, environmentalists and politicians behind a shared goal.”ThePoke UK, 9 Nov 2011

Fort Collins’ New Belgium Brewery has been creating specialty brews since 1991, and sustainability director Jenn Orgolini said anyone who enjoys the company’s product should be concerned about the climate. . “If you drink beer now, the issue of climate change is impacting you right now.” Some of those impacts include higher prices for raw materials or scarcer products such as specialty hops.

Tokyo governor Shintaro Ishihara warned on Wednesday the 2016 Olympics could be the last Games, with global warming an immediate threat to mankind. “It could be that the 2016 Games are the last Olympics in the history of mankind,” Ishihara told reporters at a Tokyo 2016 press event ahead of the vote.

“Global warming is getting worse. We have to come up with measures without which Olympic Games could not last long. “Scientists have said we have passed the point of no return,” said Ishihara. Reuters, 30 Sep 2009

bushfire alert

Unless action is taken now to reduce carbon dioxide emissions, Australia will be unable to manage future catastrophic bushfires, leading climate scientists have warned.

The co-director of the University of NSW’s climate change research centre, Andy Pitman, says there will be a 100 to 200 per cent increase in bushfire risk by 2100 if Australia continues on its path of high emissions.

But if Australia was able to meet the low emission guidelines set by the inter-governmental panel on climate change, the increase in bushfire risk would be just 20 to 30 per cent by 2100, he said.

Ice Age revisited

Sweden’s mountains are growing greener. At the border between woods and bare mountain, trees that require warm temperatures, such as oak, elm, maple, and black alder, have become established for the first time in 8,000 years.

This is shown in current studies led by Leif Kullman, professor of physical geography at Umeå University in Sweden.

Over the last century, the temperature has risen by more than one degree. The cooling trend over several thousand years is broken, and this has triggered changes in flora, fauna, and landscapes.

In important respects, the present state is similar to what occurred directly after the latest ice age.

monkeys on the move

The white-bearded De Brazza’s monkeys were found in the Great Rift Valley, a place they had never been spotted before, Richard Leakey, a prominent white Kenyan credited with ending the slaughter of the nation’s elephants, told Reuters in Nairobi. “That is telling us a lot about the climate change scenarios we are looking at now,” he said. “It puts climate change as the most critical consideration as we plan for the future.”Planet Ark, 1 Nov 2007

to someone with purple-tinted glasses, everything looks purple

The local inhabitants along the river Dyak had a lot to say about climate change….Raimie, our wildlfe guide has also noticed that the heat arrives earlier in the dry season and that the season lasts longer.

One of the consequences of this shift is a greater prevalence of fire, and Raimie mentioned that a year earlier, in neighbouring Kalimantan, 1000 orang-utans burned to death — a significant proportion of the world’s population.

Such catastrophes are reported occasionally in the media but the link with climate change is almost never made.

wakeup call

Climate change is bringing animals out of hibernation prematurely, making them lose weight and causing them stress, Italian scientists said yesterday. Spring-like temperatures too early in the year are waking animals up sooner and putting their feeding and breeding habits out of kilter with the environment.The Guardian, 8 Jun 2006

it’s all in the mind

This week 2,500 of the world’s leading environmental scientists warned politicians of the drastic global warming which will result if governments fail to reduce greenhouse gases. Scientists have warned that the early arrival of Spring may lift people’s spirits but can also trigger migraines. A study has shown temperature rises increase the number of people requiring hospital treatment for debilitating headaches.

swarms

Scientists say global warming could be about to boost fly populations in the world’s cooler nations, bringing swarms of blowflies to countries like England.

Researchers from Southampton University used computer models to analyse how a rise in tempterature could affect populations of houseflies and bluebottles, the British name for blowflies.

Based on the data, they estimated that Britains’s fly numbers could rise by 250 per cent by 2080.

Squirrels beat the heat

Canadian squirrels have evolved earlier breeding times.

Squirrels with genes for earlier breeding were probably favored because this allows them to take advantage of an earlier spring and hoard more pinecones for winter survival

…..as the climate has warmed in recent decades, Canadian squirrels have evolved shifts in their breeding times that make them more successful in warmer climates.

They’re invading!…but then again maybe not

Ancient viruses have been lying dormant in Siberian permafrost for centuries. But global warming is about to change that. Scientists have made another massive discovery of ancient (and giant) viruses hidden dormant in the permafrost. As the planet warms, finding these things—and waking them—is going to become more commonplace.

….. the distant possibility does exist, and as more and more polar thawing occurs, our statistical chance of finding something will grow. But Dr. James Van Etten, a professor at University of Nebraska-Lincoln thinks that a viral outbreak is a worry you can put out of your head. “Certainly,” he says, “I would not lose any sleep over this issue.” The Daily Beast, 27 Sep 2015

too many black sheep in the family

Scientists have discovered milder winters are turning the dark coats of Soay sheep on Hirta in the St Kilda archipelago lighter. Dr Maloney, of the University of Western Australia, said: “Our finding that the proportion of dark-coloured Soay sheep decreased over the past 20 years as ambient temperature increased could be interpreted in several ways, the most parsimonious being that dark colouration has provided an energetic advantage in winter that is being attenuated in a warming climate.

Hopeful news at last – the U.N. is becoming irrelevant!

After another U.N. climate conference gave only modest results, European Climate Commissioner Connie Hedegaard says the process needs to provide a “substantial answer” to global warming in two years to remain relevant. I think that it has to deliver a substantial answer to climate change in 2015, Hedegaard said. “If it fails to do so, then I think this critical question will be asked by many more.”

pestilence

According to several leading climate scientists and public health researchers, global warming will lead to higher incidence and more intense versions of disease.

The direct or indirect effects of global warming might intensify the prevalence of tuberculosis, HIV/AIDS, dengue and Lyme disease, they said, but the threat of increased health risks is likely to futher motivate the public to combat global warming.

“The environmental changes wrought by global warming will undoubtedly result in major ecologic changes that will alter patterns and intensity of some infectious diseases,” said Gerald Friedland, professor of medicine and epidemiology and public health at the Yale School of Medicine.

bio-degradable footwear

The uncomfortable truth is that overconsumption is a major factor in climate change, Jo Paoletti, an associate professor of American Studies at the University of Maryland says. “We buy much more clothing today than we did a generation ago, and too much of it is ‘ast,’ disposable fashion.”

If we define ‘sustainable fashion’ as made of particular [eco-friendly] fibers but still ready for Goodwill in a few months, we are deluding ourselves,” says Jo Paoletti.

There’s good news: several companies are already stepping up to contribute to the industry’s sustainability and to work toward lessening its environmental impact, as Politiwicz points out.

Puma, for example, is manufacturing biodegradable footwear. Levi’s recently launched an initiative to use less water in its jeans manufacturing process. Even fast fashion behemoth H&M has launched its own Conscious Collection sustainability initiative.
