September brought the world's record-breaking hot streak to an end - but don't chill out
According to data released by the US National Oceanic and Atmospheric Administration (NOAA) this week, September 2016 was the second-hottest September on record globally. Until then, every month since April 2015 was the hottest for its month on record (the hottest August, the hottest July, and so on).
Back in April 2015, Donald Trump was still considering whether to run for US president while Malcolm Turnbull was still five months away from becoming Australian Prime Minister. Since then we’ve also seen two new versions of the iPhone come out.
So our 16-month streak of record heat is a long one. In fact it’s the longest in NOAA’s 137-year records of global temperatures. Other global temperature series have slightly different records but the general story is the same – the last couple of years have been very hot.
Rising temperaturesHeat records are a clear sign that temperatures are rising. If they weren’t, you wouldn’t expect too many new records after more than a century of measurements. For example, to get a record-hot September now means that it has to be hotter than all the other Septembers that have gone before, all 136 of them.
Statistically we might expect record hot or cold months about only once a decade if temperatures were flat. Records are often clustered, one hot month is usually followed by another one.
Of course we do have a trend in global temperatures and this makes breaking heat records much more likely. Without the effect of climate change it’s very unlikely we’d be experiencing so many records.
In contrast, we haven’t experienced a cold record in a very long time. The last record-cold year globally was in 1911, but there have been 20 record-hot years since then up to 2015.
Several studies have shown that even on more local scales we experience far more hot records than cold records, including in Australia where we’ve experienced 12 times as many hot records as cold ones. The increase in hot records has been attributed to climate change.
The El Niño after the ‘hiatus’The last couple of years have been strongly influenced by El Niño. The expulsion of heat from the ocean into the lower atmosphere (where most of our temperature measurements are made) means that these periods are about one-tenth of a degree more than average.
In comparison, human-caused climate change has warmed the planet by about one degree Celsius. Combining the warming signal of climate change with the El Niño has led to the record warmth over the past 16 consecutive months.

The 2015-16 El Niño came off the back of the so-called warming hiatus. From about 2000-14 the Earth experienced very little warming. This has been linked to decade-length variability in the Pacific Ocean. Since 2014, the warming has restarted and this has meant that record heat across the globe is now more likely.
Australia avoids the heatIf you’re reading this in Australia you might be thinking, where’s all this heat? After a warm summer and a record-hot autumn the winter was pretty wet with cities such as Melbourne feeling cool compared to previous winters. But across Australia, this winter past was the sixth warmest and second wettest on record.

More recently, September was actually cooler than average (one of the few spots across the globe to not be abnormally warm) as well as the second wettest since 1900. The wetter-than-normal conditions were associated with very warm waters to the west of Australia feeding in more moisture across the continent. The wet weather prevented heat from building up.
Australia only represents a small part of the globe though, and overall the world is still experiencing near-record warmth. Over the next few months we’re less likely to see global heat records fall. Now that the El Niño has well and truly disappeared, replaced by cooler waters in the central Pacific, the record warmth is likely gone. For now.
This won’t prevent 2016 as a whole almost certainly becoming the hottest year on record. This will make it the third consecutive record-breaking hot year globally.
And when the next big El Niño comes, combining with a growing human-induced climate change effect, we can be confident more heat records will fall.

Corporate climate risk is all about turning a profit, not fixing the problem

Climate change poses a major threat to the future of humanity. Extreme weather, rising seas, ocean acidification and biodiversity collapse will undermine many of the systems on which we depend. We’ve even seen a recent example of this, with South Australia’s storm and blackout illustrating the vulnerability of our society to extreme weather.
Risk has become a central construct for how businesses should respond to climate change. As Hank Paulson, former Secretary of the US Treasury has argued, “climate change is not only a risk to the environment but it is the single biggest risk that exists to the economy today”.
The G20 is currently investigating how companies are exposed to climate risk, and how they disclose that risk to consumers.
However, instead of dealing with the larger problem of rapid and systemic decarbonisation, most businesses construct climate risk solely through the lens of profitability and market opportunity.
As part of a broader study into corporations and the climate crisis, we recently published an article in the journal Organization exploring how corporations have responded to climate risks.
What is risk?Risk management has become a central feature of corporate language. Risk was translated into management in the 1990s after catastrophes and scandals such as the collapse of Barings Bank and the Brent Spar controversy at Shell.
The core assumption here is that risk is somewhere outside the company: it just has to be found and captured. The perception is that corporations are exposed to a variety of objective risks that can be managed through rational decision-making. This might include cost–benefit analysis based on probabilities and consequences. The aim is to make uncertainty manageable.
How companies construct risk involves a number of processes. In relation to climate change, companies seek to break up a complex concept into smaller parts that can be addressed by specific corporate practices and policies. These include:
physical risks such as the potential for extreme weather events such as storms, droughts and fires to impact upon business operations (most evident amongst resource, energy and manufacturing companies with vulnerable infrastructure and supply chains)
regulatory risk, including the potential for governments to regulate greenhouse gas emissions and implement carbon taxes and cap and trade mechanisms
market risks, such as new disruptive, low-carbon technologies that challenge established business models (such Tesla’s reinvention of electric vehicles and mass production of battery storage)
reputational risks, such as the threat of negative customer or community perceptions of companies’ environmental impacts (such as growing consumer awareness of environmentally harmful products such as palm oil or fossil-fuel based energy).
To address these risks, companies seek to minimise the threats and maximise the opportunities. These include practices such as scenario planning and retrofitting infrastructure for extreme weather events, engaging politically and lobbying for better regulation, scanning the market for competitive threats, investing in R&D for new “green” products, and actively marketing and branding themselves as “green” businesses.
However, for corporations to prosper from climate change, the risks associated with it have to be meaningful in a business sense. They have to be able to be valued in monetary terms. For instance, putting a price on carbon means emissions can be factored into business strategies, which then stimulate investments in “green” energy and technologies.
As one manager in a financial services organisation confided to us: “The easiest thing to do, is to go carbon trading. There’s a way to make money!”
These risk framings are then institutionalised through corporate roles and practices (such as pricing carbon internally, restructuring activities to identify new products and markets, and actively managing customer and employee perceptions of corporate activities).
As another sustainability manager outlined: “My job is to keep their risk as low as possible … from regulatory right through to perception and reputation.”
But risk is more complex than thatHowever, these risk constructions often fail to fully account for the physical and political complexities of climate change.
In insurance for example, the reliance on historical climate models often fails to account for new and extreme weather events. As one senior manager explained:
I mean most people didn’t think it hailed in Melbourne until last year (2010). There was another one in Perth, you know it was classic. It was known in the industry as “unmodelled risk”, which means there isn’t a detailed model of the risk that you can use to price it. Perth – hail in Perth was unknown. I mean completely unknown.
Moreover, consumers, employees and communities often surprise companies and wrong-foot corporate risk modelling.
For instance, despite the claims by financial institutions that they are “sustainability” leaders by reducing their carbon emissions and encouraging corporate clients to adopt more climate friendly practices, NGOs and critics have emphasised how these statements conflict with continued investments in fossil-fuel based energy projects.
This has culminated in a global movement of fossil-fuel divestment which undermines the social legitimacy of these investments.
Corporate risk constructions also exclude non-market understandings which underpin personal and social identity. For example, energy companies which promote coal-seam gas as a cleaner energy source have been caught off guard by vehement political battles with agricultural landholders and communities objecting to fracking as a harmful activity. Here, community and environmental concerns collide with corporate risk calculations, which focus on profitability and the opportunity of increasing commodity prices.
By ignoring these factors, and constructing risk in a way that maximises opportunities and profit, corporations emphasise a vision of human mastery over nature. Like latter-day wizardry, corporate risk calculations suggest that markets and capital can, not only control the natural world, but somehow anticipate it.
These risk calculations downplay the need for radical change and emphasise “business as usual”. Ironically, the devastating environmental change that is supposedly being anticipated and managed by corporate risk management is locked in to an ever more terrifying degree.

Quality of life v the push for fracking and airport expansion | Letters
It is easy sometimes to wonder whether our governments care about anything except money; yet they refuse to put a monetary value on those aspects of life that lend enchantment (Mary Dejevsky, Quality of life has a price. The frackers should pay it, 17 October). A beautiful view is one of these; so is peace and quiet. So is the ability to keep one’s windows open at night.
These blessings are disappearing at great speed, as the skies fill up, and as lorries, cars and machines are added to our beloved landscapes. We are told that “those affected by fracking” might be compensated, but I do not believe that many people would rather have £10,000 than the peace and quiet, and the grassy view that will vanish, with their clean drinking water, as the frackers appear. It is generally noise that provides the majority of council complaints. For example, between January and September 2014, councils in the UK received 200,220 noise complaints, almost half the total number (Report, 18 March 2014).

Europe's offshore wind industry booming as costs fall
The European Union’s push away from fossil fuels toward renewables, along with falling costs, has seen offshore wind thrive with turbines being installed from the Irish to the Baltic Seas, reports Environment 360
On a sunny October morning, our boat passes the run-down relicts of Liverpool’s maritime past and heads down the river Mersey and into the Irish Sea. As we steam offshore, I see in the distance a cluster of tall structures that soon reveal themselves to be towers of a wind turbine array. Arriving at the windfarm, six miles offshore, the turbines rise as high as 650ft, taller than the tallest church in the world. Each of the turbines’ three shiny metallic rotor blades is nearly 300ft long.
“A single rotation of an eight-megawatt turbine will cover the daily electricity consumption of an average British household,” says Benj Sykes, vice president of Dong Energy Wind Power, the company that is constructing and co-owns this wind project, as the boat rocks in five-foot swells.

Japan to face criticism at international summit for flouting whaling ban
Japanese fleets have killed more than 300 minke whales in the Southern Ocean despite a court ruling and three-decade-old ban
Japan is likely to face international criticism at a whaling summit this week for killing whales in the Southern Ocean in defiance of a court ruling and a three-decade-old ban.
Japanese fleets killed more than 300 minke whales, many of them pregnant, when they resumed so-called scientific whaling in 2015-16 after a hiatus the year before because the international court of justice decided the hunts were not scientific and should cease.

Great Barrier Reef scores D for health for fifth year in a row
Results of annual report card based on data collected before bleaching killed a fifth of the reef’s coral, suggesting next year’s results will be even worse
The Great Barrier Reef has been given a D on a report card for its overall health by the federal and Queensland governments for the fifth year in a row.
The results of the annual report card were based on data collected before this year’s climate change-induced bleaching event that killed about a fifth of the reef’s coral, suggesting next year’s results will be even worse.

Listening for the shovels, hooves and curses of long-dead miners
Frosterley, Weardale The footpaths were silent and deserted, but, at every turn, there were signs of the days when they echoed with the sounds of human labour
On a windless morning, when the sun had barely reached sufficient elevation to skim the dew on the grass, the footpaths around the old quarries were silent and deserted. And yet, at every turn, there were signs of days when this valley echoed with the sound of human voices and people’s labour.
I stood among the ruins of Harehope Gill lead mine, where only a single wall still stands, and tried to imagine it two centuries ago, when it was at its productive peak: the clop of hooves as ponies dragged squeaky-wheeled wagons laden with lead ore from the mine level tunnel; the thud of picks on rock; clanging shovels; rattle of broken stone tipped on to spoil heaps; and the shouts and curses of labouring miners. Now, just silence, except for the trickling of water.
