BoE governor fears regulation to tackle global warming will leave assets ‘stranded’

By on January 6, 2017 in Climate Change, Energy, Technology

Only about one-third of the world’s 1,000 largest companies provide effective disclosure of the risks they face due to climate change, according to Bank of England Governor Mark Carney. At the same time, Carney stated that the transition to an environmentally sustainable future in the coming decades provides an annual opportunity worth trillions of dollars for companies and financiers.

Former New York City mayor Michael Bloomberg has been leading efforts to make climate-related financial disclosures more transparent, and together with Carney he revealed recommendations for a voluntary disclosure code in London in December.

The prospect of tougher global climate action has grown since delegates from nearly 200 countries agreed on a UN climate change accord in Paris in December 2015, which has new been ratified. Still, it is not clear if the agreement will deliver the cuts in global greenhouse gas pollution that scientists say are needed to ensure global temperatures do not rise more than 2°C from pre-industrial times.

NASA creates a stunning new 3-D view of CO2

NASA released a new visualization of a year in the life of carbon dioxide, showing how carbon dioxide twists and turns around the globe like a river. Scientists modeled the atmosphere using similar techniques as they use with fluid dynamics, based on data from NASA’s OCO-2 satellite, which takes nearly 100,000 carbon dioxide measurements a day.
Understanding the sources of carbon pollution is important for climate negotiations as well as regional plans for how to reduce it.

The recommendations from the World Economic Forum focus on short-term energy futures: Unless we are able to sharply reduce global GHG emissions by the early 2020s, our scope for mitigating the most dangerous consequences of climate change will be compromised.

As the significant reductions in wind and solar power continue, the potential for decarbonising the electric power sector has never been better.

Climate change health crisis: Global experts launch Lancet Countdown

An international, multi-disciplinary research initiative was launched at the COP22 climate talks taking place in Morocco. It brings together leading experts to track and analyze the impacts of climate change on public health.

The interrelation of climate change and public health is becoming increasingly clear. The Lancet Countdown builds on the findings of the 2015 Lancet Commission on Health and Climate Change, which concluded that climate change posed both a “potentially catastrophic risk to human health”, while conversely being “the greatest global health opportunity of the 21st century” if the right steps are taken.

Air pollution linked to increased mental illness in children

Higher levels of air pollution may correspond to higher rates of mental health disorders in children e.g. kids and teens, according to a new study conducted in Sweden.

Researchers found that, in areas with higher levels of pollution, there were more medications dispensed for psychiatric conditions in children and teens, compared with areas with lower levels of air pollution.

The new findings add to previous research that has shown links between air pollution and anxiety, perceived levels of stress and mental health conditions in the general population, the researchers said in their study, published June 3 in the journal BMJ Open.

“The results can mean that a decreased concentration of air pollution — first and foremost, traffic-related air pollution — may reduce psychiatric disorders in children and adolescents,” lead study author Anna Oudin, a public health researcher at Umeå University in Sweden, said in a statement.

One striking aspect of the new research is that Sweden has low levels of air pollution, but the researchers still saw the link even below levels of 15mcg/m3. “Sweden is not a country that suffers from very bad air quality, said Kelly. “This suggests that other countries and cities have an even bigger challenge, as they will have to make significant improvements to their air quality so that it is even cleaner than Sweden’s.”

Prof Frank Kelly, at King’s College London, said the research was important. “This builds on existing evidence that children are particularly sensitive to poor air quality probably because their lifestyles increase the dose of air pollution they are exposed too – ie they are more active – and that developing organs may be more vulnerable until they fully mature.”

Air pollution rising at an alarming rate in world’s cities

world_pollution

Outdoor air pollution has grown 8% globally in the past 5 years, with billions of people around the world now exposed to dangerous air, according to new data from more than 3,000 cities compiled by the World Health Organisation (WHO).

Air pollution levels were generally much lower for cities in developed countries with Sydney, New York and London registering 17, 16 and 22 micrograms per cubic metre for PM10s respectively. However, the data only includes measurements for particulates and does not include forms of air pollution such as NO2 and ozone.

“We have a public health emergency in many countries. Urban air pollution continues to rise at an alarming rate, wreaking havoc on human health. It’s dramatic, one of the biggest problems we are facing globally, with terrible future costs to society,” said Dr Maria Neira, director of public health at the WHO in Geneva.

Outdoor air pollution causes more than 3m deaths a year – more than malaria and HIV/Aids – and is now the biggest single killer in the world. The toll is expected to double as urban populations increase and car numbers approach 2bn by 2050.

Air pollutants such as sulphates, nitrates and black carbon penetrate deep into the lungs and into the cardiovascular system, posing the greatest risks to human health, says the UN.

“As urban air quality declines, the risk of stroke, heart disease, lung cancer, and chronic and acute respiratory diseases, including asthma, increases for the people who live in them. When dirty air blankets our cities the most vulnerable urban populations – the youngest, oldest and poorest – are the most impacted,” said Flavia Bustreo, WHO assistant director general.

“More than 80% of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed the World Health Organisation limits.

It is crucial for city and national governments to make urban air quality a health and development priority,” said Dr Carlos Dora, co-ordinator of the WHO’s Interventions for Healthy Environment programme. “When air quality improves, health costs from air pollution related diseases shrink, worker productivity expands and life expectancy grows. Reducing air pollution also brings an added climate bonus, which can become a part of countries’ commitments to the climate treaty.”

Air pollution linked to premature birth and $4.3B cost to the United States

By on April 4, 2016 in Air pollution, Climate Change, Health

Premature birthAir pollution is now linked to premature birth in the U.S., causing over 3% of these events, about 16,000 each year. The annual cost has reached $4.3 billion, according to a new study by the NYU Langone Medical Center in New York City (Particulate Matter Exposure and Preterm Birth: Estimates of U.S. Attributable Burden and Economic Costs, Trasande et al. 2016).

Researchers say the costs include prolonged hospital stays, long-term use of medications for the infant, as well as lost economic productivity for the mother. The report also found that the number of premature births linked to air pollution was highest in urban counties. Air pollution, the research says, introduces toxic chemicals to the mother such as fine particulate matter, which in turn leads to a cascade of ill effects: immune system stress, a weakened placenta, preterm birth and a host of potential mental and physical disabilities for the baby.

In the weeks immediately after birth, premature infants often have difficulty breathing and digesting food. They can also encounter longer-term challenges such as impaired vision, hearing, and cognitive skills as well as social and behavioral problems. Pregnant women may want consider moving away from areas with heavy pollution or at least purchase air filters and close windows during high traffic periods.

“Air pollution comes with a tremendous cost, not only in terms of human life, but also in terms of the associated economic burden to society,” says Dr. Leonardo Trasande, a professor at the medical center who led the research. “It is also important to note that this burden is preventable, and can be reduced by limiting emissions from automobiles and coal-fired power plants.”

Dr. Trasande plans to share the findings with policymakers. He also says the number of premature births in the U.S. remains well above those of other developed countries. The report, published in Environmental Health Perspectives, is the first to trace the frequency and cost of premature births related to air pollution.

 

 

Climate Change is a ‘Medical Emergency’ experts warn

NASA, NOAA Analyses Reveal Record-Shattering Global Warm Temperatures in 2015

NASA, NOAA Analyses Reveal Record-Shattering Global Warm Temperatures in 2015. 2015 was the warmest year since modern record-keeping began in 1880, according to a new analysis by NASA’s Goddard Institute for Space Studies. The record-breaking year continues a long-term warming trend — 15 of the 16 warmest years on record have now occurred since 2001

According to the 2015 Lancet Commission on Health and Climate Change, the threat to human health from climate change is so great that it could undermine the last 50 years of gains in development and global health.

Extreme weather events such as floods and heat waves bring rising risks of infectious diseases, poor nutrition and stress, the specialists said, while polluted cities where people work long hours and have no time or space to walk, cycle or relax are bad for the heart as well as respiratory and mental health.

Almost 200 countries have set a 2 degrees C global average temperature rise above pre-industrial times as a ceiling to limit climate change, but scientists say the current trajectory could lead to around a 4 degrees C rise in average temperatures, risking droughts, floods, storms and rising sea levels.

“That has very serious and potentially catastrophic effects for human health and human survival,” said Anthony Costello, director of University College London’s (UCL) Institute for Global Health, who co-led the report. “We see climate change as a major health issue, and that’s often neglected in policy debates,” he told reporters at a briefing in London. The report, commissioned and published by The Lancet medical journal, was compiled by a panel of specialists including European and Chinese climate scientists and geographers, social, environmental and energy scientists, biodiversity experts and health professionals.

It said that because responses to mitigate climate change have direct and indirect health benefits – from reducing air pollution to improving diet – a concerted effort would also provide a great opportunity to improve global health.

The report said direct health impacts of climate change come from more frequent and intense extreme weather events, while indirect impacts come from changes in infectious disease patterns, air pollution, food insecurity and malnutrition, displacement and conflicts.

“Climate Change is a medical emergency,” said Hugh Montgomery, director of UCL’s institute for human health and performance and a co-author on the report. “It demands an emergency response using technologies available right now.”

The panel said there were already numerous ways to bring about immediate health gains with action on climate change.

Burning fewer fossil fuels reduces respiratory diseases, for example, and getting people walking and cycling more cuts pollution, road accidents and rates of obesity, diabetes, heart disease and stroke. 

Cardiovascular disease is the world’s number one killer, leading to some 17 million deaths a year, according to World Health Organization data.

“There’s a big (energy) saving in people using calories to get around, and there are some immediate gains from more active lifestyles,” Montgomery said.

The commission also recommended the creation of a new global independent body with the task of monitoring climate change and global health. This coalition would report every two years on the health effects of climate change, track the progress of policies designed to mitigate climate change and make new suggestions on how to further adapt to climate change and implement low-carbon, sustainable health systems.

Air pollution now a public global health emergency: WHO

The World Health Organisation has issued a stark new warning about deadly levels of pollution in many of the world’s biggest cities, claiming poor air quality is killing millions and threatening to overwhelm health services across the globe.

Before the release next month of figures that will show air pollution has worsened since 2014 in hundreds of already blighted urban areas, the WHO says there is now a global “public health emergency” that will have untold financial implications for governments.

The latest data, taken from 2,000 cities, will show further deterioration in many places as populations have grown, leaving large areas under clouds of smog created by a mix of transport fumes, construction dust, toxic gases from power generation and wood burning in homes.

“We have a public health emergency in many countries from pollution. It’s dramatic, one of the biggest problems we are facing globally, with horrible future costs to society,” said Maria Neira, head of public health at the WHO, which is a specialist agency of the United Nations. “Air pollution leads to chronic diseases which require hospital space. Before, we knew that pollution was responsible for diseases like pneumonia and asthma. Now we know that it leads to bloodstream, heart and cardiovascular diseases, too – even dementia. We are storing up problems. These are chronic diseases that require hospital beds. The cost will be enormous,” said Neira.

The latest scientific research, published in the journal Nature, suggests that air pollution now kills more people a year than malaria and HIV combined, and in many countries accounts for roughly 10 times more deaths than road accidents.

According to the WHO, air quality is deteriorating around the world to the point where only one in eight people live in cities that meet recommended air pollution levels.

AURAIA @ Paris COP21, a unique social & economic opportunity

By on November 27, 2015 in Climate Change

Climate Change effects such as increased temperatures, changing precipitation patterns, rising sea levels, and more frequent weather-related disasters are already being experienced around the world.

UN Climate Change Conference

United Nations Climate Conference

In 2014, near the end of the warmest year on record, leaders representing over 190 countries set in Lima a plan to reach a global deal within the next year addressing climate change. This unique opportunity, being formed over the past two decades, is culminating in December 2015 at the United Nations Climate Conference (COP21) in Paris, where each nation will cement its commitment to reducing emissions.

If successful, the agreement will be a breakthrough in curbing the sources and effects of climate change and leading us to a prosperous low-carbon future. The momentum surrounding Paris provides a clear window for change for our future generations !
