Of hungry badgers and hidden worms

The Guardian - Thu, 2016-08-25 14:30

Old Warden, Bedfordshire In this parched landscape it was clear the hedgerow fruit had not ripened a moment too soon for the badgers

It took only a few dry weeks for the fields on the plateau above the village to forget that it had ever rained. The clay soil was beginning to crack, the footpath had turned to a sun-baked dirt track and there was no yield underfoot. Every bump and stone was hard and uncompromisingly contoured, jabbing at an instep, stubbing a toe.

The worms had become dustbowl refugees in this parched landscape, sinking deep underground. Far below my feet, they would be aestivating, bunched up in knots, coated in their own mucus in a hibernation-like suspension of active life, waiting for moisture to come again.

The Industrial Revolution kick-started global warming much earlier than we realised

The Conversation - Thu, 2016-08-25 06:27
Britain's industrial pioneers couldn't have known how they would affect the climate. Henry Gastineau

In the early days of the Industrial Revolution, no one would have thought that their burning of fossil fuels would have an almost immediate effect on the climate. But our new study, published today in Nature, reveals that warming in some regions actually began as early as the 1830s.

That is much earlier than previously thought, so our discovery redefines our understanding of when human activity began to influence our climate.

Determining when global warming began, and how quickly the planet has warmed since then, is essential for understanding how much we have altered the climate in different parts of the world. Our study helps to answer the question of whether our climate is already operating outside thresholds that are considered safe for human society and functional ecosystems.

Our findings show that warming did not develop at the same time across the planet. The tropical oceans and the Arctic were the first regions to begin warming, in the 1830s. Europe, North America and Asia followed roughly two decades later.

Surprisingly, the results show that the southern hemisphere began warming much later, with Australasia and South America starting to warm from the early 20th century. This continental-scale time lag is still evident today: while some parts of Antarctica have begun to warm, a clear warming signal over the entire continent is still not detectable.

The warming in most regions reversed what would otherwise have been a cooling trend related to high volcanic activity during the preceding centuries.

Global warming got underway much earlier in the north.

By pinpointing the date when human-induced climate change started, we can then begin to work out when the warming trend broke through the boundaries of the climate’s natural fluctuations, because it takes some decades for the global warming signal to “emerge” above the natural climate variability.

According to our evidence, in all regions except for Antarctica, we are now well and truly operating in a greenhouse-influenced world. We know this because the only climate models that can reproduce the results seen in our records of past climate are those models that factor in the effect of the carbon dioxide released into the atmosphere by humans.

These remarkable findings were pieced together from the most unusual of sources – not thermometers or satellites, but rather from natural climate archives. These include coral skeletons, ice cores, tree rings, cave deposits and ocean and lake sediment layers, all of which record the climate as they grow or accumulate.

These archives provide long records that extend back 500 years – well before the Industrial Revolution – and provide a critical baseline for the planet’s past climate, one that is impossible to obtain otherwise.

But why is there no clear warming fingerprint yet seen across Antarctica? The answer most likely lies in the vast Southern Ocean, which isolates the frozen continent from the warming happening elsewhere.

The westerly winds that circulate through the Southern Ocean around Antarctica keep warm air masses from lower latitudes at bay. Ozone depletion and rising greenhouse gas concentrations during the 20th century have also caused this wind barrier to get stronger.

The Southern Ocean currents that flow around Antarctica also tend to move warmer surface waters away from the continent, to be replaced with cold deeper water that hasn’t yet been affected by surface greenhouse warming. This process could potentially delay Antarctica’s warming by centuries.

Ocean insulation

The delay in warming observed in the rest of the southern hemisphere is something we do not yet fully understand. It could simply be because fewer records are available from the southern hemisphere, meaning that we still don’t have a full picture of what is happening.

Alternatively, like Antarctica, the southern hemisphere’s oceans could be holding back warming – partly through winds and currents, but perhaps also because of “thermal inertia”, whereby the ocean can absorb far more heat energy than the atmosphere or the land before its temperature markedly increases. Bear in mind that the southern half of the globe has much more ocean than the north.

Essentially, then, the coolness of the southern hemisphere’s vast oceans could be “insulating” Australasia and South America from the impact of global warming. The question is, for how long?

If our evidence of delayed warming in the southern hemisphere holds true, it could mean we are in in for more climate surprises as global warming begins to overcome the thermal inertia of our surrounding oceans. Could the recent record warming of Australian waters, and the subsequent damage to the Great Barrier Reef, be an early sign that this is already occurring?

Recent research suggest that the mass bleaching event of the reef was made 175 times more likely by climate change. Following the recent severity of such extremes, a better understanding of how anthropogenic greenhouse warming is already impacting the southern hemisphere is critical.

What to do about it

Leading scientists from around the world met in Geneva last week to discuss the goal of limiting average global warming to 1.5℃ – the more ambitious of the two targets enshrined in the Paris climate agreement.

Last year, global temperatures crossed the 1℃ threshold, and 2016 is on track to be 1.2-1.3℃ above our climate baseline.

But here’s the kicker. That baseline is relative to 1850–1900, when most of our thermometer-based temperature records began. What our study shows is that for many parts of the world that estimate isn’t good enough, because global warming was already under way, so the real baseline would be lower.

The small increases in greenhouse gases during the 19th century had a small effect on Earth’s temperatures, but with the longer perspective we get from our natural climate records we see that big changes occurred. These fractions of a degree of extra warming might seem insignificant at first, but as we nudge ever closer to the 1.5℃ guardrail (and potentially beyond), the past tells us that small changes matter.

Sustainable housing's expensive, right? Not when you look at the whole equation

The Conversation - Thu, 2016-08-25 06:27

Low-energy or zero-energy housing is international best practice, but is still considered costly. Part of the problem is that studies of housing standards typically use only cost-benefit analysis to assess their value, and so often wrongly conclude that sustainable housing is unaffordable.

Our new research shows how such analyses may miss some flow-on financial benefits – such as reduced energy bills and lower mobility costs. Most importantly, these analyses also overlook effects on householders' health and quality of life arising from factors such as improved thermal comfort.

Sustainable housing can also have important benefits for some of the most vulnerable members of our community, as the report released this week shows.

The environmental performance of Australian housing has improved slowly, associated with changes in minimum building regulations and the creation of subsidies such as solar rebates. This is despite sustainable housing having many documented benefits, including lower (or non-existent) utility bills and greenhouse gas emissions, and improved comfort and health.

Conventional cost-benefit analyses exclude these benefits. That leaves significant gaps in the story that could be used to support investment in sustainable housing.

What did the study assess?

Our study involved a three-year, mixed-method evaluation of a small sustainable housing development in Horsham, Victoria. Commissioned by the Victorian Department of Health and Human Services (DHHS), the study used both quantitative and qualitative methods, which are rarely combined to assess housing policy and environmental performance.

Four two-bedroom, nine-star-rated (under the National House Energy Rating Scheme, NatHERS) houses were built to maximise passive solar principles. The design elements and technologies used included (partial) reverse brick-veneer construction, double-glazed windows, solar hot water, a 1.5-kilowatt solar photovoltaic system and a shared 5,000-litre rainwater tank.

The houses were built without air conditioning. They do have ceiling fans and gas heating in the living area.

We evaluated these nine-star houses against seven control houses also in Horsham and built to DHHS standards, with a six-star NatHERS rating. We also compared the results to a DHHS technical model of standard industry practice. We conducted a traditional cost-benefit analysis, technical performance analysis (utility consumption, internal temperature), three rounds of interviews with the householders during different seasons, and a personalised household sustainability assessment.

Through a traditional cost-benefit lens, the nine-star housing was not financially viable for DHHS. Even if DHHS was able to capture the savings to the householders, payback was only achieved within 40 years for one of the four dwellings in a high-energy-price future. This was due to higher-than-expected capital costs for the sustainability initiatives.

However, resale value could be up to A$40,000 higher per unit. The technical performance analysis also identified significant benefits for the nine-star households. These included reduced utility consumption and bills. One occupant told us:

Look, I haven’t paid any off my power bill in six months and I’m still in credit.

We found that these households:

  • were A$1,000 a year better off as a result of reduced utility consumption (including solar feed-in tariff);

  • purchased 45% less electricity than the control households (and 73% less than the standard industry practice);

  • consumed 22% less water (30% less than the industry standard);

  • had 40% less CO₂ environmental impact from power use (63% less than the industry standard); and

  • were comfortable with the indoor temperature of their house for 10% more of the time (even without air conditioning).

Extreme weather events magnified the comfort benefits. On a second consecutive day above 41℃, the nine-star houses were up to 16.6℃ cooler (without air conditioning) compared to the department’s standard six-star house (which had air conditioning).

This meant householders could stay at home during heatwaves rather than needing to seek alternative accommodation, which happened sometimes for the control households. One occupant said:

…in summer I would sit down at the supermarket, you know, because it was cool … [Now] I can stay home and veg out.

Interviews with residents highlighted positive social outcomes from living in sustainable housing, which supported the technical data. The benefits they described included improved health and personal finances.

For example, these householders said they had extra spending money due to low (or no) utility bills. This meant they could buy children Christmas presents, avoid personal debt and lay-by, or go on a holiday.

I do go clothes shopping on occasion now instead of thinking, “Oh God, I have to go and lay-by that.”

Householders described how this led to reduced stress and better mental health.

The research demonstrates that the housing sector’s over-reliance on cost-benefit analysis may be overlooking important benefits (and detriments) of different housing arrangements. Combining qualitative and quantitative evaluation methods can help uncover a more detailed and complete picture of how housing affects people’s lives.

Our research also highlights how sustainable housing benefits extend beyond the environment. These flow-on effects can improve the living conditions of some of the most vulnerable members of society. This, in turn, potentially reduces pressure on health and other support systems and sectors.

Combining sustainable and affordable housing

Our study is part of an emerging body of research that challenges the idea that sustainable housing is unaffordable.

The evidence increasingly shows that sustainability and good design can improve affordability when fuller cost-benefit analyses are undertaken and non-monetised social, health and well-being benefits are considered.

To date, however, there is limited “real world” research into people living in sustainable housing, particularly in the affordable housing sector. Without more multidisciplinary evaluations of this kind, we are left with an incomplete picture of the benefits of this type of housing.

Such studies will be critically important as Australia seeks to make the transition to a more sustainable future. Climate change and increased livability costs are likely to add to the challenges for social housing organisations and the tenants who depend on their services.

An open letter to the Prime Minister on the climate crisis, from 154 scientists

The Conversation - Thu, 2016-08-25 06:26

Dear The Hon. Malcolm Turnbull MP, Prime Minister of Australia,

The following is an open letter signed by 154 Australian atmospheric, marine, environmental, biological and medical scientists, including several leading climatologists, for your and your government’s attention.

There is no Planet B

In July 2016, global temperatures soared to the hottest in the 136 years of the instrumental record, 0.1℃ warmer than previous warm Julys in 2015, 2011 and 2009. It followed a succession of rising temperatures, moving from 0.42℃ above average in 2000, to 0.87℃ above average by 2015.

Developments in the atmosphere-ocean system reported by major climate research organisations (including NASA, the US National Oceanic and Atmospheric Administration, the US National Snow & Ice Data Center, the UK Met Office Hadley Centre, the Tyndall Centre, the Potsdam Institute; the science academics of dozens of nations; and in Australia the CSIRO and Bureau of Meteorology) include:

We are concerned that global warming, amplified by feedbacks from polar ice melt, methane release from permafrost, and extensive fires, may become irreversible, including the possible collapse of the Atlantic Meridional Overturning Circulation, a crucial component of the global climate system that transfers heat from the tropics to the North Atlantic.

According to James Hansen, NASA’s former chief climate scientist, “burning all fossil fuels would create a different planet than the one that humanity knows“. Joachim Schellnhuber, Germany’s chief climate scientist, has summed up the situation by saying: “We’re simply talking about the very life support system of this planet.”

We note your broad agreement with this point, in light of your 2010 statement that:

…we are as humans conducting a massive science experiment with this planet. It’s the only planet we have got… We know that the consequences of unchecked global warming would be catastrophic… We as a human species have a deep and abiding obligation to this planet and to the generations that will come after us.

While the Paris Agreement remains unbinding and global warming has received minimal attention in the recent elections, governments worldwide are presiding over a large-scale demise of the planetary ecosystems, which threatens to leave large parts of Earth uninhabitable.

We call on the Australian government to tackle the root causes of an unfolding climate tragedy and do what is required to protect future generations and nature, including meaningful reductions of Australia’s peak carbon emissions and coal exports, while there is still time.

There is no Planet B.

Human-induced climate change began earlier than previously thought

The Guardian - Thu, 2016-08-25 03:23

Signs of warming appear as early as 1830 say researchers, whose analysis will help build accurate baseline of temperature before influence of human activity

Continents and oceans in the northern hemisphere began to warm with industrial-era fossil fuel emissions nearly 200 years ago, pushing back the origins of human-induced climate change to the mid-19th century.

The first signs of warming from the rise in greenhouse gases which came hand-in-hand with the Industrial Revolution appear as early as 1830 in the tropical oceans and the Arctic, meaning that climate change witnessed today began about 180 years ago.
