Donald Trump vows to end climate change funding

At the Williston Basin Petroleum Conference on Thursday, Republican presidential nominee Donald Trump promised to end climate change funding and to greatly expand U.S. fossil fuel production.

After clinching the GOP nomination for President, Donald Trump outlined his energy and environmental policies yesterday to thousands at the Williston Basin Petroleum Conference in Bismarck, North Dakota. During his speech, for which he received many standing ovations, Mr. Trump emphasised the need for an "America First" agenda.

"We're going to rescind all the job-destroying Obama Executive Actions including the Climate Action Plan and the Waters of the United States Rule," Trump said to applause from the audience.

"We're gonna save the coal industry," he said. "And other industries threatened by Clinton's extremist agenda. And it is indeed an extremist agenda. Perhaps even worse than Obama. I'm going to ask trans-Canada to renew its permit application for the Keystone Pipeline."

In December 2015, a global climate change pact was agreed at the UN COP21 summit. This represented a consensus of the 196 parties attending and included measures to reduce the global temperature rise from 4.5°C to 3.5°C by 2100. While far from adequate, it was the biggest milestone to date in terms of halting climate change, with nations around the world promising to curtail their greenhouse gas emissions and pursuing efforts to limit the rise to 2.0°C or below.

The United States pledged emission cuts of nearly 30% by 2025 (relative to 2005 levels) and claimed it was on track for an 80% cut by 2050. One of the main ways in which this goal would be achieved was through stricter regulations on power plants – the single largest source of emissions – to be introduced by the Obama administration.

In addition to boosting renewables, lowering their costs, and increasing the energy efficiency of homes and workplaces, the plan would also create tens of thousands of new jobs, improve air and water quality, prevent 3,600 premature deaths, prevent 90,000 asthma attacks in children and prevent 300,000 missed workdays and schooldays. Consumers would save an estimated $155 billion from 2020-2030.

However, in his speech yesterday, Trump made it clear that he would "cancel the Paris climate agreement" and "stop all payments of the United States tax dollars to UN global warming programs." He also criticised the Endangered Species Act for being used to limit oil and gas operations and promised to "revoke policies that impose unwarranted restrictions on new drilling."

Interestingly, Trump recently applied for permission to erect coastal defences at his seaside golf resort in County Clare, Ireland. A permit application for the wall specifically refers to erosion caused by rising sea levels and extreme weather as a result of global warming. This is despite him calling it "pseudoscience," "bullshit" and "a total hoax."

Real Clear Politics' national polling shows that Donald Trump and Hillary Clinton are now almost level, following a sharp decline in the latter's popularity over the last two months. Their average scores now stand at roughly 43% each. The full speech at the Williston Basin Petroleum Conference is available on YouTube.

More than a billion people exposed to coastal flooding by 2060

To mark the start of Christian Aid Week, a new report launched by the charity highlights the cities most at risk from future coastal flooding.

 

one billion flood risk 2060

 

Christian Aid's report – Act Now Or Pay Later: Protecting a billion people in climate-threatened coastal cities – shows that more than a billion people will be exposed to coastal flooding by 2060, through a combination of sea level rise, storm surges and extreme weather. Published yesterday, the report reveals that people living in three of the biggest carbon polluting countries will be most at risk: China, India and the USA.

According to projections for the year 2070 – based on the latest IPCC reports – India's Kolkata and Mumbai top the list of cities whose populations are most exposed to coastal flooding, with 14 million and 11.4 million respectively. The first seven cities on the list are from Asia, followed by Miami in 8th.

Miami is also forecast to suffer the brunt of the financial losses from coastal flooding by 2070, topping a separate list with an eye-watering $3.5 trillion of threatened assets. The USA is likely to pay a hefty price for its carbon footprint – among the world's highest when measured on a per capita basis – as New York also comes in third place with $2.1 trillion. China's Guangzhou splits the two American cities with exposed assets of $3.4 trillion.

In total, of the top 20 most financially vulnerable cities, half are from either of these two countries: four from the USA, six from China.

Report author Dr Alison Doig, Christian Aid's Principal Climate Change Advisor, said the figures should be a wakeup call ahead of next week's World Humanitarian Summit in Istanbul (23rd-24th May).

"We are facing a head on collision between the growth of coastal urban areas and climate change which makes coastal flooding more likely," she said. "This perfect storm is likely to bring about a heavy human and financial toll, unless we do something about it.

"Cruelly, it will be the poor that will suffer the most. Although the financial cost to cities in rich countries will be crippling, wealthier people will at least have options to relocate and receive insurance protection.

"Evidence shows that from New Orleans to Dhaka, it is the poorest who are most vulnerable, because they have the worst infrastructure and no social or financial safety nets to help them recover."

Dr Doig added: "There is a chance this horrifying vision of the future can be avoided. It is striking that the cities facing the most severe impacts are in countries with high contributions of carbon emissions. The first thing we can do is speed up the global transition away from dirty fossil fuels to the clean, renewably energy of the future. We can also do more to prepare for such occurrences. For every $1 spent on reducing the risk of disasters, we save around $7 later. Such investment is a no brainer."

Ahead of next week's World Humanitarian Summit, UN General Secretary Ban Ki-moon has called for the percentage of global aid spent on disaster risk reduction to be doubled to 1%. This would bring the figure to $1 billion. Christian Aid is calling for a rise to 5%.

Dr Doig added: "This billion dollars would go some way to help protect people in these cities now, alleviating the threat for the billion vulnerable people at risk from coastal flooding by 2060."

In another ranking, the report lists which nations will have the most people living in exposed coastlines by 2060. China tops the list, followed by India and Bangladesh. The UK comes in 22nd.

"In the UK, we've experienced in recent years the winter flooding that has left large parts of the country deluged," Dr Doig continued. "But these figures show that it's not just more rainfall we need to be wary of. The people living along our coastlines will become vulnerable to rising tides unless we do something about climate change."

The report goes on to examine how men and women are affected differently by climate-related disasters, with women on the whole suffering more acutely. It also shows examples of where Christian Aid is offering practical assistance to help the most vulnerable deal with the climate impacts they are already facing.

Bangladesh is among the most vulnerable countries to climate change and is ranked 142nd out of 187 nations on the UN's Human Development Index. However, donations to Christian Aid are helping lift people away from the floodwaters. One example is Feroza Begum and her family, whose home was flooded multiple times and at one point was underwater for 18 days. Thanks to help from Christian Aid partner organisation GUK, their home and surrounding land was raised onto a sturdy plinth.

Feroza was also given livestock and climate-resistant seeds to diversify her income and become more resilient. "Because of this plinth, I feel better," she told Christian Aid. "Now I have been able to make a small plantation and grow some vegetables. I am doing much better and feel much safer."

Christian Aid's report was published on the same day that NASA confirmed April 2016 was the hottest April on record, beating the previous record set in 2010 by 0.24°C, the largest margin ever. It is likely that 2016 will be the hottest year on record globally.

Leopards have lost 75% of their historic range

The most detailed ever study of leopard populations reveals that the animals have lost three-quarters of their habitat range since 1750.

 

leopard

 

The leopard (Panthera pardus), one of the world's most iconic big cats, has lost as much as 75 percent of its historic range, according to a paper published in the scientific journal PeerJ. Conducted by partners including the National Geographic Society's Big Cats Initiative, international conservation charities the Zoological Society of London (ZSL) and Panthera and the International Union for Conservation of Nature (IUCN) Cat Specialist Group, this study is the first known attempt to produce a comprehensive analysis of leopards' status across their entire range and all nine subspecies.

The research found that historically, leopards occupied a vast range of approximately 35 million square kilometres (13.5 million square miles) throughout Africa, the Middle East and Asia. Today, however, they are restricted to just 8.5 million square kilometres (3.3 million square miles).

To obtain their findings, the researchers spent three years reviewing more than 1,300 sources on the leopard's historic and current range. The results appear to confirm conservationists' suspicions that, while the entire species is not yet as threatened as some other big cats, leopards are facing a multitude of growing threats in the wild, and three subspecies have been almost completely wiped out.

Lead author Andrew Jacobson, of ZSL's Institute of Zoology, University College London and the National Geographic Society's Big Cats Initiative, stated: "The leopard is a famously elusive animal, which is likely why it has taken so long to recognise its global decline. This study represents the first of its kind to assess the status of the leopard across the globe and all nine subspecies. Our results challenge the conventional assumption in many areas that leopards remain relatively abundant and not seriously threatened."

In addition, the research found that while African leopards face considerable threats, particularly in North and West Africa, leopards have also almost completely disappeared from several regions across Asia – including much of the Arabian Peninsula and vast areas of former range in China and Southeast Asia. The amount of habitat in each of these regions is plummeting, having declined by nearly 98 percent.

"Leopards' secretive nature, coupled with the occasional, brazen appearance of individual animals within megacities like Mumbai and Johannesburg, perpetuates the misconception that these big cats continue to thrive in the wild – when actually, our study underlies the fact that they are increasingly threatened," said Luke Dollar, co-author and program director of the National Geographic Society's Big Cats Initiative.

Philipp Henschel, co-author and Lion Program survey coordinator for Panthera, said: "A severe blind spot has existed in the conservation of the leopard. In just the last 12 months, Panthera has discovered the status of the leopard in Southeast Asia is as perilous as the highly endangered tiger. The international conservation community must double down in support of initiatives protecting the species. Our next steps in this very moment will determine the leopard's fate."

Leopards are capable of surviving in human-dominated landscapes, provided they have sufficient cover, access to wild prey and tolerance from local people. In many areas, however, their habitat is converted to farmland and native herbivores are replaced with livestock for growing human populations. This habitat loss, prey decline, conflict with livestock owners, illegal trade in leopard skins and parts, and legal trophy hunting are all factors contributing to leopard decline.

Complicating conservation efforts for the leopard, Jacobson noted: "Our work underscores the pressing need to focus more research on the less studied subspecies, three of which have been the subject of fewer than five published papers during the last 15 years. Of these subspecies, one – the Javan leopard (P. p. melas) – is currently classified as critically endangered by the IUCN, while another – the Sri Lankan leopard (P. p. kotiya) – is classified as endangered, highlighting the urgent need to understand what can be done to arrest these worrying declines."

Despite this troubling picture, some areas of the world inspire hope. Even with historic declines in the Caucasus Mountains and Russia's Far East / Northeast China, leopard populations in these areas appear to have stabilised and may even be rebounding with significant conservation investment through the establishment of protected areas and increased anti-poaching measures.

"Leopards have a broad diet and are remarkably adaptable," said Joseph Lemeris, a National Geographic Society researcher and paper co-author. "Sometimes the elimination of active persecution by government or local communities is enough to jumpstart leopard recovery. However, with many populations ranging across international boundaries, political cooperation is critical."

Climate exodus predicted in North Africa and the Middle East

Experts have calculated that in future decades, North Africa and the Middle East may become so hot that human habitability is compromised.

The number of climate refugees could increase dramatically in the future. Researchers at the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario.

Temperatures during summer in the already very hot Middle East and North Africa will increase at more than twice the rate compared to the worldwide average for global warming. This means that on hot days, regions south of the Mediterranean will exceed 46°C (114°F) by mid-century. Such extremely hot days will occur five times more often than was the case at the turn of the millennium. In combination with increasing air pollution by windblown desert dust, environmental conditions may become intolerable and force people to migrate. More than 500 million people live in North Africa and the Middle East, a region where climate change is already evident. The number of extremely hot days has doubled since 1970.

"In future, the climate in large parts of the Middle East and North Africa could change in such a manner that the very existence of its inhabitants is in jeopardy," says Jos Lelieveld, Director at the Max Planck Institute for Chemistry and Professor at the Cyprus Institute.

Lelieveld and his team investigated how temperatures will develop in the Middle East and North Africa over the course of the 21st century. The result of their study is deeply alarming. Even if Earth's temperature were to increase on average by only two degrees Celsius compared to pre-industrial times, the temperature in summer in these regions will increase more than twofold. By mid-century, during the warmest periods, temperatures will not fall below 30 degrees at night, and during daytime they could rise to 46 degrees Celsius (approximately 114 degrees Fahrenheit). By the end of the century, midday temperatures on hot days could even climb to 50 degrees Celsius (approximately 122 degrees Fahrenheit). Another finding: heat waves will occur ten times more often than they do now.

Unbearably hot: average temperatures in winter will rise by 2.5 degrees Celsius (left) by the mid-21st century, and in summer by five degrees Celsius (right) if global greenhouse gas emissions continue to increase according to the business-as-usual scenario (RCP8.5). The cross-hatching indicates that the 26 climate models used are largely in agreement, and the dotting indicates an almost complete match. © MPI for Chemistry

 

In addition, the duration of heat waves will be dramatically prolonged. Between 1986 and 2005, it was very hot for an average period of about 16 days; by the middle of the century it will be unusually hot for 80 days per year. By the end of the century, up to 118 days could be unusually hot, even if greenhouse gas emissions decline again after 2040.

"Climate change will significantly worsen the living conditions in the Middle East and in North Africa," says atmospheric researcher Jos Lelieveld, who is convinced that climate change will have a major impact on the health of people in these regions. "Prolonged heat waves and desert dust storms can render some regions uninhabitable, which will surely contribute to the pressure to migrate."

The research team has also published findings on the increase of fine particulate air pollution in the Middle East. It was found that desert dust in the atmosphere over Iraq, Saudi Arabia, and in Syria has increased by up to 70% since the beginning of this century. This is mainly attributable to an increase of sand storms as a result of prolonged droughts. It is expected that climate change will contribute to further increases, which will worsen environmental conditions in the region.

In their study, Lelieveld and his team first compared data from 1986 to 2005 with predictions from 26 climate models over the same time period. It was shown that the measurement data and model predictions matched extremely well, which is why the scientists used these models to project future climate conditions for the period from 2046 to 2065 and the period from 2081 to 2100.

The researchers based their calculations on two future scenarios:

• The first scenario, called RCP4.5, assumes that global emissions of greenhouse gases will start decreasing by 2040 and that the Earth will be subjected to warming by 4.5 Watts per square metre by 2100. This corresponds to the target set at the recent UN summit, which means that global warming should be limited to less than two degrees Celsius.

• The second scenario, RCP8.5, is based on the assumption that man-made greenhouse gas emissions will continue to grow unabated. It is therefore called the "business-as-usual" scenario. According to this scenario, the mean surface temperature of the Earth will increase by more than four degrees Celsius compared to pre-industrial times.

In both scenarios, the strongest temperature increase in the Middle East and North Africa is expected during the summer – when it is already very hot – and not during winter, which is more common in other parts of the globe. This is primarily caused by desert warming amplification in regions such as the Sahara. Deserts do not buffer heat well, which means that the hot and dry surface cannot cool by the evaporation of ground water. Since the surface energy balance is controlled by heat radiation, the greenhouse effect of gases such as CO2 and water vapour will increase disproportionately.

Regardless of which scenario becomes a reality, Lelieveld and his team agree that climate change will cause a significant deterioration in living conditions for the people of North Africa and the Middle East; and that consequently, sooner or later, many people will have to leave the region. From a geopolitical point of view, the resulting influx of refugees into southern Europe and elsewhere could be highly disruptive.

Fossil fuels could be phased out worldwide in a decade

The worldwide reliance on burning fossil fuels to create energy could be phased out in a decade, according to an article published by a major energy think tank.

 

fossil fuels energy phased out within a decade

 

Professor Benjamin Sovacool, from the University of Sussex in the United Kingdom, believes that the next great energy revolution could take place in a fraction of the time of major changes in the past. But it would take a collaborative, interdisciplinary, multi-scalar effort to get there, he warns. And that effort must learn from the trials and tribulations from previous energy systems and technology transitions.

In a paper published by the peer-reviewed journal Energy Research & Social Science, he analyses energy transitions throughout history and argues that only looking at the past can often paint an overly bleak and unnecessary picture. Moving from wood to coal in Europe, for example, took between 96 and 160 years, whereas electricity took 47 to 69 years to enter into mainstream use.

But this time, the future could be different, he says – the scarcity of fossil fuel resources, the threat of climate change and vastly improved technological learning and innovation could greatly accelerate a global shift to a cleaner energy future.

The study highlights numerous examples of speedier transitions that are often overlooked by analysts. For example, Ontario completed a shift away from coal between 2003 and 2014; a major household energy programme in Indonesia took just three years to move two-thirds of the population from kerosene stoves to LPG stoves; and France's nuclear power programme saw supply rocket from four per cent of the electricity supply market in 1970 to 40 per cent in 1982. Each of these cases has in common strong government intervention along with shifts in consumer behaviour, often driven by incentives and pressure from stakeholders.

"The mainstream view of energy transitions as long, protracted affairs, often taking decades or centuries to occur, is not always supported by evidence," says Professor Sovacool. "Moving to a new, cleaner energy system would require significant shifts in technology, political regulations, tariffs and pricing regimes, and the behaviour of users and adopters.

"Left to evolve by itself – as it has largely been in the past – this can indeed take many decades. A lot of stars have to align all at once. But we have learnt a sufficient amount from previous transitions that I believe future transformations can happen much more rapidly."

To summarise, while the study suggests that the historical record can be instructive in shaping our understanding of macro and micro energy transitions, it need not be predictive.

While his forecast may seem outlandish and overly optimistic, there are signs that he might be correct. The worldwide installed capacities of solar and wind power, for example, continue to grow exponentially as costs plummet and efficiencies improve. Likewise, the number of electric cars in the world is rising exponentially and passed the one million mark in 2015. In Europe, the Netherlands is proposing a ban on all gas and diesel car sales by 2025, while UK firm Ecotricity is looking at "green gas", a carbon-neutral alternative to fracking. Meanwhile in the United States, Elon Musk last year unveiled a new battery system – the Powerwall – that could revolutionise clean energy storage for homes and businesses.

Self-driving trucks complete journey across Europe

Fleets of self-driving trucks this week completed the European Truck Platooning Challenge.

 

self driving trucks fleet 2016

 

As part of the world's first cross-border initiative with smart trucks, six "platoons" of semi-automated trucks have completed their journeys from various cities across Europe, reaching their final destination at the Port of Rotterdam on 6th April.

They were participating in the European Truck Platooning Challenge organised by the Dutch government as part of its EU Presidency. The European Automobile Manufacturers' Association (ACEA) and commercial vehicle members – including Daimler, Scania and Volvo – are active partners of the initiative with each supplying a platoon. One set of trucks made by Scania travelled over 2,000 km and crossed four borders. Daimler made headlines in 2014 when the company demonstrated the world's first autonomous truck in Magdeburg, Germany, and in 2015 its Freightliner Inspiration Trucks gained a licence for road use in Nevada.

Truck platooning – which has the potential to make transport cleaner, safer and more efficient – is the linking of two or three trucks in a convoy. These vehicles follow each other at a fixed, close distance, by using connectivity technology and automated driving support systems.

 

 

 

Using this technique cuts fuel use by 15%, prevents human error from causing accidents, and reduces congestion, according to research firm TNO. Expenses can be lowered significantly.

Two trucks doing 100,000 miles annually can save €6,000 ($6,840) on fuel by platooning, compared to driving on cruise control. Safety is greatly improved by using technology such as Volvo's emergency braking system and Daimler's Highway Pilot Connect – systems with braking reaction times of under 0.1 seconds, compared to 1.4 seconds for a human driver. A Wi-Fi connection between the trucks ensures synchronised braking and can prevent sudden jolt/shock effects.

When operating in platoon mode, a convoy of three semi-autonomous trucks can travel much closer together – requiring only 80 metres of road space, from end to end. For comparison, if they were driven by humans, they would need to fill 185 metres of road. Congestion on roads will therefore be greatly reduced if more and more self-driving vehicles are deployed in the future, while pollution can also be lowered.

 

 

 

Melanie Schulz, Dutch minister for Infrastructure and the Environment who spearheaded this initiative, commented: "The results of this first ever major try-out in Europe are promising. The hands-on experience gained here will be very useful in the informal European transport council on 14th April in Amsterdam. It will certainly help my colleagues and I discuss the adjustments needed to make self-driving transport a reality."

There are still a number of barriers standing in the way of truck platooning across Europe. These barriers are not of a technical nature as platooning technology exists already; rather they are caused by differences in legislation between the EU member states: "Harmonisation is needed if we want a wide-scale introduction of platooning," stated Harrie Schippers, President of DAF Trucks.

Sufficient demand is also crucial, to ensure the right level of market uptake. Following the Truck Platooning Challenge, there have been encouraging expressions of interest from the business community and the transport sector, including Unilever and major Dutch supermarkets. The testing phase is the most important next step. More and more national governments are offering industry the opportunity to test their latest vehicles and technologies, thereby also supporting efforts to increase public awareness, understanding and acceptance. However, this is also vital on a pan-European scale.

"It is precisely for this reason that we believe that the European Truck Platooning Challenge has been a huge success: it has fostered much-needed cooperation between all relevant stakeholders right across the EU, facilitating cross-border driving and encouraging compatibility on legal and technical issues," said Schippers. "We look forward to harvesting the learnings from this initiative so that, together, we can make truck platoons a common sight on Europe's roads in the future."
