Risky Business: How Companies Are Getting Smart About Climate Change

The Conversation

The divestment movement is gaining momentum – and is just one of the emerging risks from climate change that businesses face. The Paris climate agreement not only signalled social change but also sent the market a strong signal to move away from carbon-intensive investment.
The divestment movement may be seen by some businesses invested in fossil fuels as a risk. But it is not the only force shaping how companies address climate change. So, what are some of the other factors in rethinking climate risk?

Evolving social norms
The Paris Agreement recently gained more steam with ratification by the United States and China. This signalled the intent of these leading global economies to commit to helping to limit global warming to 2℃. Achieving this will require a transition to a low-carbon or decarbonised economy. China, for example, has been aware of how important this is since 2008.
Since the launch of the Low Carbon Economy Index by PricewaterhouseCoopers in 2009, companies have been better equipped to understand and measure private sector climate risk. This has flow-on effects to just about all human behaviours, and has had a particularly significant impact on private equity investments.
In particular, pension funds and the insurance sector are among the leading sectors in considering future climate risk within and across their portfolios. This is facilitating evolving social norms around climate change. These changes have long been recognised as critical for climate change mitigation and adaptation.

The role of law
Liability risk remains at the forefront in current trends. The acceptance of legal responsibility demonstrated by global leaders' ratification of the Paris Agreement is all the more interesting when we consider recent developments in climate litigation.
Some argue that, in future, there will be parallels between tobacco and asbestos tort litigation and climate litigation, given that the consequences of a changing climate have been well known for decades, and widely cited by scholars and practitioners alike. It is therefore difficult for a legal entity to claim ignorance of climate risks.
Internationally, a decision in 2015 held Dutch public officials legally accountable in reducing emissions. In the United States, instances of litigation have increasingly focused on companies' disclosure of known future climate risk. Pressure has also been building on Exxon Mobil as evidence emerges that the company may have lied to shareholders about this known risk.
In Australia, some recent interesting developments in coastal planning law are contributing to a more coherent body of climate law.
Fiduciary duties are an important aspect of rethinking climate risk. In law, they can require companies to disclose future risk. A failure to disclose on "the business strategies, and prospects for future financial years" under the Corporations Act may be considered a breach of the law and subject to ASIC enquiry.
While some regulatory guides exist for how to achieve general compliance, recent submissions to the Senate inquiry into carbon risk disclosure have argued that specific regulatory guidance for future climate risk is needed. Arguably, disclosing future risks includes future climate risks to assets and company investments.
The courts are moving where regulation and policy may be slower to act. In April 2016, the New South Wales Supreme Court relaxed the hurdles for shareholders to bring action against a company in a case where an insurer, HIH, led the market to believe it was trading more profitably and had greater net assets than was the case. This artificially inflated the HIH share price, resulting in shareholders suffering a loss because they bought overpriced shares. This case is important for shareholder class actions because it is the first time the court has accepted the principle of indirect market based causation.
In a similar way, a failure to disclose known future climate risk in required disclosure documents could potentially amount to misleading and deceptive conduct. This is particularly the case where companies may fail to disclose their asset exposure to climate change impacts.

Technological risk
The World Economic Forum's Global Risks Report 2016 noted that the number-one risk to the global economy was a failure to mitigate and adapt to climate change.
Some argue that technological responses, including carbon capture and storage, continue to require research and development input. Others suggest that investing in renewable energy, particularly for developing countries, will lead to more sustainable global outcomes including, importantly, social equity.
While mitigation technologies continue to compete for long-term success, investors need to be increasingly aware of where and how they prioritise their mitigation efforts.

Where to now for Australian companies?
The 2016 carbon risk disclosure inquiry was due to publish its report in June 2016 but lapsed due to the federal election. This Senate inquiry ought to recommence as a matter of priority.
Additional legal mechanisms that will have flow-on effects for evolving social norms and for rethinking climate risk could include legislative change to require the inclusion of reporting asset exposure risks, under the National Greenhouse and Energy Reporting Act.
Climate risk, the transition to a low-carbon economy, evolving social norms and the continued growth of climate law evidence a need to ensure coherence across economic, social and governance frameworks.

Oceans Are Absorbing Almost All Of The Globe’s Excess Heat

New York Times - Tim Wallace

This year is on track to be the third consecutive hottest year on record. Where does that heat go? The oceans, mostly.

         Where the Oceans Have Been Colder and Hotter Than Average
Average temperatures from each decade compared with the 20th-century average.
Ocean temperatures have been consistently rising for at least three decades. Scientists believe that global sea surface temperatures will continue to increase over the next decade as greenhouse gases build up in the atmosphere.
According to a report by the International Union for Conservation of Nature released last week, the Southern Hemisphere has experienced intense warming over the past decade, with strong heat accumulation in the midlatitude regions of the Pacific and Indian Oceans.
Natural patterns such as El Niño and La Niña can have year-to-year effects on temperatures. Individual storms can also influence ocean temperatures for months or longer. But the overall temperature trends by decade reveal a backdrop of human-caused warming.

Record High Annual Mean Surface Temperatures, 2015

Last year, nearly all observed ocean surface temperatures registered above average because naturally occurring conditions caused by El Niño combined with human-induced warming. About a quarter of those observations broke record highs.

Heat Accumulates in the Oceans
Since 1955, more than 90 percent of the excess heat retained by the Earth as a result of increased greenhouse gases has been absorbed by the oceans, leaving ocean scientists like Eric Leuliette at the National Oceanic and Atmospheric Administration feeling that 90 percent of the climate change story is being ignored.
Estimated Heat Accumulation
Amounts in zettajoules, or sextillions of joules, relative to 1971 levels.
For several decades, more energy has been absorbed than emitted at the top of Earth's atmosphere. According to Gregory Johnson, an oceanographer at NOAA, the rate of energy gained between 1971 and 2010 was roughly equal to the power required to run 140 billion 1,500-watt hair dryers over the same number of years. The rate has only increased in the past decade. This excess energy has largely been sucked up by the oceans, which have a huge capacity to store heat. As the oceans store more heat, however, they expand. Scientists have shown that over the past decade, this thermal expansion has caused about one-third of the rise in sea levels.

What Hotter Oceans Bring
The oceans act as Earth's enormous heat sponge, sheltering continents and the people who live on them from atmospheric extremes. The near-surface ocean takes only decades to warm in response to elevated greenhouse gas concentrations, but the deep ocean will take centuries to millenniums, raising sea level all the while. In the meantime, warmer ocean temperatures may also increase the destructive potential of extreme weather, like cyclones and hurricanes. In fact, the effects of warmer waters are already widespread.

Ice Melt and Sea Level Rise
The Greenland ice sheet is studded with meltwater streams, rivers and lakes. The rate of melt is alarming many scientists. Both ice melt and thermal expansion are causing a significant rise in global sea levels.

Marine Species Are at Risk
Warmer temperatures are threatening some marine animal and plant species, like these bleached coral on the Great Barrier Reef. Scientists also predict that some birds, like the black-legged kittiwakes in Norway, may soon die off in warmer waters.

Habitats Are Changing
The warmer conditions have allowed some jellyfish, like the comb jellyfish, pictured above, in Narragansett Bay, to have longer seasons. Others have expanded their territory. In some cases, United States fisheries have shifted north to cooler waters.

 Bindi, Robert and Terri Irwin have joined Queensland scientists tracking 150 saltwater crocodiles from Cape York's Wenlock River to try and determine the impact of climate change on the animals and reduce the number of attacks on humans.
The annual crocodile research trip takes place in the Steve Irwin Wildlife Reserve in August.
The 2016 expedition captured 23 crocodiles, 11 of which were added to the research program.
The University of Queensland's Professor of Zoology, Craig Franklin, said 150 crocodiles in the Wenlock River had been tagged since 2008.

 Professor Franklin said the data would give scientists an understanding of the types of thermal environments crocodiles liked to live in.
"They do have a preferred temperature range and if it gets too warm for them up top, they may move further south to cooler waters," he said.
During their latest trip, a crocodile tagged in 2008 was recaptured and retagged with an acoustic tag, which lasts 10 years.
"We're going to be tracking that one individual animal for 18 years," Professor Franklin said.
"It was a big animal, definitely one of the alpha males in the river system.
"It had grown by about 18 centimetres [since 2008] and it was close to 4.6 metres long."
Professor Franklin said the acoustic tag was implanted in the crocodile, underneath its left forelimb, during a minor surgical procedure.
"It sends out like a morse code and we have listening stations along the Wenlock River so when it swims past, it tells us the animals in that location," he said.
"It also tells us what the body temperature is of that animal.

"In the times of climate change and global warming, what's going to be fascinating to see is how it will influence the biology of crocodiles."

Living 'safely' with crocodiles a study aim
Professor Franklin said some crocodiles were fitted with satellite transmitters that monitor the diving behaviour.
"So far we have five million recordings of body temperature from the 150 animals and also their location data," he said.
"From their behaviour, to their movement patterns, to their thermal physiology."
Professor Franklin said the data was important in predicting the movements and range of crocodiles as the planet warmed up.
"We would like to educate people more broadly about living alongside crocodiles safely," he said.
"The information we're gaining definitely gives us an indication of what their behaviours are like and when it's best not to be in crocodile habitat or close to the water."
