the vanishing cow!

Is Global Warming Leading To Cow Infertility? Reproductive efficiency has suffered a dramatic decrease since the mid-1980s despite rapid worldwide progress in genetics and management of high producing dairy herds.

Researchers from the University of Barcelona propose that summer heat stress is likely to be a major factor related to low fertility in high producing dairy herds, especially in countries with warm weather. Scientific Blogging, 5 Sep 2007

worse than we thought – melting polar ice caps!

Climate scientists are saying that global warming, as evidenced by melting polar ice caps, is worse than predicted by the Intergovernmental Panel on Climate Change and that global emissions must peak by 2015 if climate chaos, and resulting human social chaos is to be avoided.

Green-labour alliances can inspire the broad-based community campaigns needed to make a just transition to renewable energy and new green jobs.

Geoff Evans is an environmental scientist and social ecologist, researching transitions to sustainability. He is a former Director of the Mineral Policy Institute, now working with Greenpeace on their Climate and Energy campaign.

reservations about climate models!

Climate scientists have created an index of the year when the average climate of any given region on earth will likely push outside the extreme records experienced in the past 150 years should greenhouse gas emissions continue unabated.

Research leader Camilo Mora, from the University of Hawaii, said while scientists had repeatedly warned about climate change and its likely effects on biodiversity and people, their study showed change was already upon us.

“Within my generation, whatever climate we were used to will be a thing of the past,” said Dr Mora.

Australian climate scientist Sarah Perkins, from the ARC Centre of Excellence for Climate System Science, said the study’s results were in line with the latest global projections.But she expressed reservations about the study’s time frames, saying climate models were not designed to provide projections for such precise times and locations such as a year or a city.

standing room only!

Antarctica is likely to be the world’s only habitable continent by the end of this century if global warming remains unchecked, the Government’s chief scientist, Professor Sir David King, said last week.

He said the Earth was entering the “first hot period” for 60 million years, when there was no ice on the planet and “the rest of the globe could not sustain human life”.

The warning – one of the starkest delivered by a top scientist – comes as ministers decide next week whether to weaken measures to cut the pollution that causes climate change, even though Tony Blair last week described the situation as “very, very critical indeed.”

gentoo leads chinstraps!

Heather Lynch of Stony Brook University studied breeding patterns of three species of Antarctic penguins: the Adélie, chinstrap, and gentoo.

While the Adélie and chinstrap migrate to the Western Antarctic Peninsula to breed every year, the gentoos are year-round residents. Because the Antarctic is one of the world’s most rapidly warming regions, Lynch hypothesized that these environmental changes would affect penguins’ reproduction.

She was right: Warmer temperatures have resulted in dwindling Adélie and chinstrap populations. The gentoos, however, are able to adapt to increased temperatures better since they live in the Peninsula year-round.

They’re doing it and doing it and doing it well — because they’ve been able to shift their breeding cycle earlier, their populations are actually growing.

no link too tenuous!

Well, new scientific research is mounting that could prove to be the tipping point. It just got way too personal.

Yes, early data suggests that global warming makes you fat. If anything could tip the scales, this could be it. Admittedly, the research is early and thin. But here’s how it goes.

Danish researchers were mapping the lifestyles of thousands of Danes in the MONICA studies related to cardiovascular health and obesity.

Lars-Georg Hersoug stumbled on a weird anomaly. Over a 22-year period, both thin and fat people put on weight, and the increase was proportionally the same. CO2 appears to make our blood more acidic, which influences our brain to want to eat more.

Hersoug surmised that excess CO2 in the atmosphere might be affecting hormones in the brain known as orexin neurons. Orexins stimulate eating, wakefulness and energy expenditure.

if only they’d known about climate change in 1787!

Who (you might ask) is David Brearley?

Brearley plays a critical, and entirely accidental, role in climate change because of his position as the chair of the Committee on Postponed Parts within the Constitutional Convention of 1787.

The committee opted for a middle ground solution – an electoral college that would vote on behalf of the citizens, but which would be populated based on the number of congressional seats assigned to each State in the Union.

It is this solution, brilliant at the time, that leads us to Brearley’s legacy on climate change. Because over the course of the last 200 plus years, the electoral college, which provides for stronger voting power per person in more rural and less populated states, has elected four U.S. presidents who clearly lost the popular vote (1876, 1888, 2000 and 2016).

Two of those elections have occurred during the period in which we have known about the causes and impacts of carbon dioxide emissions and climate change and in both cases, the impacts of those elections have very likely had profound impacts on our actions to address the challenge.

Flagship calls for planned retreat

The top government scientist leading Australia’s efforts to adapt to climate change has warned that some coastal communities will have to be abandoned in a “planned retreat” because of global warming.

Dr Andrew Ash, who directs the CSIRO’s Climate Adaptation Flagship program, said while some vulnerable coastal communities coud be protected by sea walls and levees, “there are going to be areas where that is not physically possible or it’s not cost effective to introduce any engineering solution and planned retreat becomes the only option.”

One of those trying to give the polar bears a break and settle the argument is James McCarthy, Alexander Agassiz Professor of Biological Oceanography and an internationally known authority on climate change.

McCarthy was among a handful of top scientists who coordinated a remarkable report by the world scientific community this year that said global warming is real, it’s here, and it’s going to be worse than we thought.

“We already see effects that [indicate] the change in climate has occurred, And the projection of some of those [effects] into the future are not a pretty scene.”

fuzzy maths

The thawing of permafrost in one region of the Arctic will cause damage worth $65 trillion, or 80 per cent of the entire global economy last year, new research suggests.

According to a UN report released last year, Policy Implications of Warming Permafrost, large-scale and irreversible thawing is already under way.

Under business-as-usual scenarios, in which nations continue to emit greenhouse gases at present rates, the total damage bill would be the equivalent of about $65 trillion, the paper said. This is about 80 per cent of the entire 2012 global economy.

If the world switched to a low-emissions path, the cost would be delayed somewhat and would end up being about $40 trillion.

Peter Atkinson, professor of geography at the University of Southampton, examined satellite images of vegetation across the northern hemisphere from the past 25 years and found signs winter was being shrunk.

Earlier this month, supermarkets Waitrose and Tesco both announced that English strawberries were ripening early and hitting the shelves a week earlier than last year.

“There is much speculation about whether our seasons are changing and if so, whether this is linked to climate change. Our study is another significant piece of the puzzle, which may ultimately answer this question,” Prof Atkinson said.

People are doing this. Let’s be clear about it. It’s not some natural phenomenon, like an earthquake or a volcanic eruption. It’s the actions of Homo sapiens.

What we are witnessing is a fundamental clash between the species, and the planet on which he lives, which is going to worsen steadily, and the more closely you observe it – or at least, the more closely I have observed it, over the past 15 years – the more I have thought that there is something fundamentally wrong with Homo sapiens himself.

worse than we thought – greenhouse gas emissions!

It seems the dire warnings about the oncoming devastation wrought by global warming were not dire enough, a top climate scientist said on Saturday.

It has been just over a year since the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) published a landmark report warning of rising sea levels, expanding deserts, more intense storms and the extinction of up to 30 per cent of plant and animal species.

But recent climate studies suggest that report significantly underestimates the potential severity of global warming over the next 100 years, a senior member of the panel said.

“We now have data showing that from 2000 to 2007, greenhouse gas emissions increased far more rapidly than we expected,” said Chris Field, who was a co-ordinating lead author of the report.

not bad, but worse!

There is a lot wrong with our world. But it is not as bad as many people think. It is worse.

Global warming is slowly but relentlessly changing the face of the planet. We are only in the early stages of this process, but already carbon dioxide in the atmosphere has reached 375 parts per million, the highest level for at least half a million years.

Temperatures are projected to rise by up to 5.8 C this century, 10 times the increase of 0.6 C in the last century, and by 40% more than this in some northern land surface areas.

This means temperatures could rise by up to 8.1 C in some parts of the world.

but who wants a padded cell in their own home?

Dr John Pockett from the Barbara Hardy Institute suggests that you take time to adapt your house to climate change.

For home builders, have a refuge at the centre of the house, that has thicker walls, so heat will take longer to get through. The other major thing (that all home owners can do) is to have a lighter coloured roof, known as a cool roof.

Make it as light coloured as your council area will allow. A cool roof reflects sunlight (including ultraviolet and infrared rays) ensuring the surface will not get as hot during the summer, leading to less heat entering living spaces.

In the mid-1980s, more than 4,000 moose roamed the forests and bogs of northwestern Minnesota. Today, there are probably fewer than 100.

Mike Schrage, a wildlife biologist with the Fond du Lac Band of Ojibwe, says researchers believe a warming climate might be causing moose to get sick.

“I do think global warming is having an impact on our moose,” said Schrage.

“I think it gets complicated between climate change and a dead moose. Because I don’t think I’m ever going to walk up to a moose carcass and be able to say, oh, it died of climate change. I think there’s a lot that happens in between.”

if they can do it, why can’t we?


So why don’t we see advanced civilizations swarming across the Universe? One problem may be climate change. It is not that advanced civilizations always destroy themselves by over-heating their biospheres (although that is a possibility).

Instead, because stars become brighter as they age, most planets with an initially life-friendly climate will become uninhabitably hot long before intelligent life emerges. Other inhabited planets in the Universe must also have found ways to prevent global warming.

Watery worlds suitable for life will have climates that, like the Earth, are highly sensitive to changing circumstances.

The repeated canceling of star-induced warming by “geobiological” cooling, required to keep such planets habitable, will have needed many coincidences, and the vast majority of such planets will have run out of luck long before sentient beings evolved. However, the Universe is immense, and a few rare worlds will have had the necessary good fortune.

It may just be that Earth is one of those lucky planets—a precious, fragile jewel in space. So, perhaps inevitably, climate change will remain a bane of the continued existence of life on such planets. ars technica, 10 Jun 2014

time to turn over a new…

This month scientists will publish research that links a decline in the nutritional quality of leaves eaten by colobus monkeys in Uganda to changes in climate over the past 30 years.

“We know if we go out and measure leaves and find patches that have a lot of protein to fibre, that’s good territory for monkeys,” said Professor Raubenheimer, from the Charles Perkins Centre at the University of Sydney.

“There are a number of experiments on plants showing that an increase in temperature and moisture has an impact on the fibre concentration. Females deprived of a balanced diet are less fertile and give birth to smaller young. The population birth rate is slowed, so you get a decline in population,” he said.

There is now clear evidence that at less than one degree of warming we are already on the precipice of catastrophic climate change that will affect the whole world – from the lower Murray to the Great Barrier Reef, and the Himalayas to Siberia and the Arctic.

just when you thought it was safe …

There have been seven shark attacks in North Carolina since June 11. This is already more than last year, when the state saw four attacks.

Although Frank J. Schwartz, a shark biologist with the University of North Carolina, Chapel Hill, says there’s too much natural variability in weather cycles to blame the recent shark attacks on global warming, George H. Burgess, the director of the International Shark Attack File at the Florida Museum of Natural History. says the link is plausible.

“Clearly global climate change is a reality and it has resulted in warmer temperatures in certain places at certain times,” says Burgess. “As warming is expected to increase, it will likely bring more sharks farther north and entice more people to get into the water, which will lead to more bites.”

with friends like these…

Any number of people offer views on the politics of climate change. Few cut to the heart of the issue like Harvard don Daniel Gilbert.

“Scientists lament the fact that global warming is happening so fast. The fact is, it’s not happening fast enough,” he said in a speeech last year.

Gilbert does not believe climate change is slow, nor does he want to see the world slide quickly into environmental catastrophe.

But he has some understanding of why people with the capacity to act, including leaders in Canberra and elsewhere, appear hamstrung when faced with the enormity of the threat of climatic disaster.

A respected psychologist, he says part of the reason most people fail to get worked up about climte change is our sensitivity to change; if something moves dramatically overnight we are alert and possibly alarmed, but if it is a gradual shift averaged across the globe over decades, it is much harder to get angry.

Another way to reflect more sunlight back into space is to increase reflectivity of the world’s marine clouds, which cover a quarter of the ocean’s surface.

John Latham and Stephen Salter of the University of Edinburgh have proposed wind-powered yachts that would spray seawater droplets into the air to produce more clouds.

Latham says that about a thousand of these vessels would be needed to make the plan effective, and that they should be deployed in the southern oceans, where most reflective marine stratocumulus clouds are.

monsoons decrease

………………………………….

We have presented evidence from observations that the equitorial Indian Ocean has warmed by about 0.6 to 0.8K during 1950 to 2002, accompanied by a dramatic weakening of the summertime SST gradient in the NIO.

In the model, the weakening of the meridional NIO_SST gradient leads to a large decrease in Indian rainfall during summer months, ranging form 2 to 3 mm per day. Reduction in the NIO_SST gradient basically weakens the model monsoonal circulation and shifts model rainfall from India to sub-Saharan Africa.

surprise finding – air conditioning makes people cooler!

Global warming has been under way for at least 25 years, and there is strong evidence that it is largely man-made and is continuing.

In recent years, temperature and mortality data from several countries shows that cold-related deaths in each age group are falling in most countries. Much of that was due to rising climatic temperature and better home heating.

A surprising finding is that the heat-related mortality rate has stabilized or fallen, despite rising temperatures. Air conditioning has been a major factor in the United States.

Heat-related deaths there are lower among people with air conditioning. An extension of air conditioning was accompanied by the virtual disappearance of heat-related death in North Carolina, despite summers becoming hotter.

Britain may be in the grip of the coldest winter for 30 years and grappling with up to a foot of snow in some places but the extreme weather is entirely consistent with global warming, claim scientists.

“Even though this is quite a cold winter by recent standards it is still perfectly consistent with predictions for global warming,” said Dr Myles Allen, head of the Climate Dynamics group at Department of Physics, University of Oxford.

“If it wasn’t for global warming this cold snap would happen much more regularly. What is interesting is that we are now surprised by this kind of weather. I doubt we would have been in the 1950s because it was much more common.”

If the North Atlantic Ocean’s circulation system is shut down — an apocalyptic global-warming scenario — the impact on the world’s food supplies would be disastrous, a study said Thursday.

It says the question is not whether this can be stopped, but whether it can be reversed over coming decades to avoid sea level rises much worse than predicted by the comparatively conservative Nobel-prize-winning Intergovernmental Panal on Climate Change – probably between two and five metres.

whales wither away

Scientists on the US Pacific coast are increasingly observing emaciated gray whales in what they fear is a sign that global warming is wreaking havoc in the whales’ Bering Sea summer feeding grounds.

The gray whales are migrating later, not going as far north, and are producing fewer calves, Steven Swartz, head researcher with the National Marine Fisheries Service told AFP.

Swartz, who with his team meticulously photograph and identify the migrating whales, estimates that at least ten percent of the population is seriously skinny.

Instead of looking plump coming off the summer months, they have noticeable depressions behind the head, with scapulas visible through the skin, and concave sections above the tail, he added. “This is enough to cause alarm.”

scientist demonstrates he has too much spare time!

Humans may evolve bizarre features such as webbed feet and eyes like cats in response to changing environments, a scientist claims today.

Experts calculated how our physical appearance could change under a number of scenarios, including a ‘water world’ if melting ice caps cause rising sea levels.

To adapt to a ‘water world’, Dr Matthew Skinner, a paleoanthropologist at the University of Kent, expects humans would develop webbed hands and eyes like those of cats to help us see in the poor lighting conditions underwater.

We would also retain a layer of baby fat into adulthood as an insulator for spending long periods submerged. Regular foraging in shallow waters could lead us to develop artificial ‘gills’ to help us breathe, extracting oxygen from the water and delivering it to the bloodstream.

This would also lead to our lung capacity becoming greatly reduced, and our rib cages shrinking.
