Islamic Climate Change Declaration Calls for Zero Emissions Strategy


18 August 2015: Islamic leaders, during an International Islamic Climate Change Symposium, called on the world's 1.6 billion Muslims to take an active role in combating climate change and urged governments to agree to a new climate change agreement in Paris.


The Symposium convened to discuss proposed messages from the Islamic community and to mobilize stakeholders in advance of the Paris Climate Change Conference in December 2015. It also aimed to seek consensus on an ‘Islamic Declaration on Climate Change,' which was drafted and circulated for comments prior to the symposium.


Approximately 60 participants, including international development policymakers, faith group leaders, academics and other experts, attended the Symposium, which met from 17-18 August 2015, in Istanbul, Turkey. The event provided the opportunity for: networking with leaders from other faiths and secular organizations; promoting inter-faith and cross-movement cooperation around joint messages; focusing on the role and contribution of Muslims to the climate movement; and securing high-level representation from participating stakeholder groups. The Symposium reaffirmed that the Islamic faith community represents a significant section of the global population and, thus, can be influential in the climate change discourse.


The 'Islamic Declaration on Climate Change,' agreed to by participants, presents the moral case, based on Islamic teachings, for Muslims and people of all faiths to act on climate change. It was drafted by international Islamic scholars from around the world and is “in harmony” with the Papal Encyclical.


The Declaration urges: setting clear targets and monitoring systems; phasing out greenhouse gas emissions; committing to 100% renewable energy and/or a zero emissions strategy; and richer countries and oil-producing states to lead the way in phasing out their emissions by 2050. The Declaration also calls for, inter alia: the provision of financial and technical support to poorer countries to phase out greenhouse gases; limiting temperature rise to below 2°C, and preferably below 1.5°C; investing in a green economy; and prioritizing adaptation efforts with support to more vulnerable countries.


In addition, the Declaration urges corporations, finance and the business sector to, inter alia: reduce their carbon footprint; commit to 100% renewable energy and/or a zero emissions strategy; adopt a “circular economy that is wholly sustainable”; consider social and ecological responsibilities; and help in divesting from the fossil fuel driven economy.


Welcoming the Declaration, UNFCCC Executive Secretary Christiana Secretary Christiana Figueres said that Islam's teachings, which emphasize the “duty of humans as stewards of the Earth and the teacher's role as an appointed guide to correct behavior,” provides guidance to take action on climate change.


The Pew Research Center data estimates that 84% of the world's population is religiously affiliated, which points to the importance of support by faith groups for climate action. Many other faiths and denominations have also called for governments to act on climate change, including through the Papal Encyclical, a forthcoming Buddhist Declaration on climate change and a Rabbinic Letter on the Climate Crisis.

Pakistan, Bangladesh face ‘state failure’ as globe heats up

Study compiled by experts from US, UK, China and India underlines migration potential from warming world

India will face a huge influx of refugees from Afghanistan, Pakistan and Bangladesh should high degrees of climate change develop, according to one of the country’s senior military officials.

Drought and flooding linked to sea level rise would place the governments of those countries under "severe stress" and lead to large-scale migration, said Vice Admiral Pradeep Chauhan, head of the Indian Naval Academy.

"In India, this would combine with an internal population shift from rural to urban areas, further increasing demographic pressure in cities," he wrote in a climate risk study backed by the UK Foreign Office.

A significant influx of migrants could further destabilise what is known as India’s "Red Corridor", a belt of land running through east India where Marxist rebels are fighting the state.

"The temptation to solve this problem through military intervention could become overwhelming," he added.

Current greenhouse gas emissions will "likely as not" mean temperature increases of 4C above pre-industrial levels by 2150 said the study, with severe implications for human health and crop yields.

A N M Muniruzzaman, a retired Bangladeshi major general, said millions of people in his country could be displaced as a result of sea level rise.

"Flooding is projected to increase in many regions, but it could be a particular problem in South Asia due to the contribution of melting glaciers," he said.

Planning battle

Chauhan’s and Muniruzzaman’s comments were based on a war gaming exercise held in Delhi in March, hosted by the Council on Energy, Environment and Water.

Former military officials from India, China, the US, the UK, Bangladesh, Germany, the Netherlands, and Finland took part, along with scientists and diplomats.

"In the game, it was notable that increasing numbers of refugees contributed to several large countries becoming more isolationist in their foreign policies," says the study.

"Participants in our exercise considered it extremely likely that climate change would exacerbate humanitarian crises over the coming decades."

Long term water stress in South Asia could become so severe previous agreements over resource sharing between India, Pakistan, China and Bangladesh "could be broken", the study warns.

"At the high degrees of climate change possible in the long-term future, participants in our scenarios exercise considered that there could even be risks to the political integrity of states that are currently considered developed and stable."

Alex Randall from the UK-based Climate Change and Migration Coalition said the document presented a "one sided view of migration" seeing it only as a security threat.

"While there is growing evidence linking climate change to changing patterns of migration, there is little evidence suggesting that migrants and refugee present the kind of security threat suggested in the report," he said.

"There is also strong evidence indicating that migration could become a key way for some people to adapt to climate change." More

Deciphering clues to prehistoric climate changes locked in cave deposits

It turns out that the steady dripping of water deep underground can reveal a surprising amount of information about the constantly changing cycles of heat and cold, precipitation and drought in the turbulent atmosphere above. The analysis of a stalagmite from a cave in north east India can detect the link between El Nino conditions in the Pacific Ocean and the Indian monsoon, a new study has found.

When the conversation turns to the weather and the climate, most people’s thoughts naturally drift upward toward the clouds, but Jessica Oster’s sink down into the subterranean world of stalactites and stalagmites.

That is because the assistant professor of earth and environmental sciences at Vanderbilt University is a member of a small group of earth scientists who are pioneering in the use of mineral cave deposits, collectively known as speleothems, as proxies for the prehistoric climate.

It turns out that the steady dripping of water deep underground can reveal a surprising amount of information about the constantly changing cycles of heat and cold, precipitation and drought in the turbulent atmosphere above.

As water seeps down through the ground it picks up minerals, most commonly calcium carbonate. When this mineral-rich water drips into caves, it leaves mineral deposits behind that form layers which grow during wet periods and form dusty skins when the water dries up.

Today, scientists can date these layers with extreme precision based on the radioactive decay of uranium into its daughter product thorium. Variations in the thickness of the layers is determined by a combination of the amount of water seeping into the cave and the concentration of carbon dioxide in the cave’s atmosphere so, when conditions are right, they can provide a measure of how the amount of precipitation above the cave varies over time. By analyzing the ratios of heavy to light isotopes of oxygen present in the layers, the researchers can track changes in the temperature at which the water originally condensed into droplets in the atmosphere changes and whether the rainfall’s point of origin was local or if traveled a long way before falling to the ground.

The value of this information is illustrated by the results of a study published May 19 in the journal Geophysical Research Letters by Oster’s group, working with colleagues from the Berkeley Geochronology Center, the Smithsonian Institution National Museum of Natural History and the University of Cambridge titled “Northeast Indian stalagmite records Pacific decadal climate change: Implications for moisture transport and drought in India.”

In the study, Oster and her team made a detailed record of the last 50 years of growth of a stalagmite that formed in Mawmluh Cave in the East Khasi Hills district in the northeastern Indian state of Meghalaya, an area credited as the rainiest place on Earth.

Studies of historical records in India suggest that reduced monsoon rainfall in central India has occurred when the sea surface temperatures in specific regions of the Pacific Ocean were warmer than normal. These naturally recurring sea surface temperature “anomalies” are known as the El Niño Modoki, which occurs in the central Pacific, and the Pacific Decadal Oscillation, which takes place in the northern Pacific. (By contrast, the historical record indicates that the traditional El Niño, which occurs in the eastern Pacific, has little effect on rainfall levels in the subcontinent.)

When the researchers analyzed the Mawmluh stalagmite record, the results were consistent with the historical record. Specifically, they found that during El Niño Modoki events, when drought was occurring in central India, the mineral chemistry suggested more localized storm events occurred above the cave, while during the non-El Niño periods, the water that seeped into the cave had traveled much farther before it fell, which is the typical monsoon pattern.

“Now that we have shown that the Mawmluh cave record agrees with the instrumental record for the last 50 years, we hope to use it to investigate relationships between the Indian monsoon and El Niño during prehistoric times such as the Holocene,” said Oster.

The Holocene Climate Optimum was a period of global climate warming that occurred between six to nine thousand years ago. At that time, the global average temperatures were somewhere between four to six degrees Celsius higher than they are today. That is the range of warming that climatologists are predicting due to the build-up of greenhouse gases in the atmosphere from human activity. So information about the behavior of the monsoon during the Holocene could provide clues to how it is likely to behave in the future. This knowledge could be very important for the 600 million people living on the Indian subcontinent who rely on the monsoon, which provides the area with 75 percent of its annual rainfall.

“The study actually grew out of an accidental discovery,” said Oster. Vanderbilt graduate student Chris Myers visited the cave, which co-author Sebastian Breitenbach from Cambridge has been studying for several years, to see if it contained enough broken speleothems so they could use them to date major prehistoric earthquakes in the area.

Myers found a number of columns that appear to have broken off in the magnitude 8.6 earthquake that hit Assam, Tibet in 1950. But he also discovered a number of new stalagmites that had begun growing on the broken bases. When he examined these in detail he found that they had very thick layers and high concentrates of uranium, which made them perfect for analysis.

Because of the large amount of water running into the cave, the stalagmite they choose to analyze had grown about 2.5 centimeters in 50 years. (If that seems slow, compare it with growth rates of a few millimeters in a thousand years found in caves in arid regions like the Sierra Nevada.) As a result, the annual layers averaged about 0.4 millimeters thick — wide enough for the researchers to get seven to eight samples per layer, which is slightly better than one measurement every two months. The amount of information about the climate that scientists can extract from the stalagmites and stalactites in a cave is amazing. But the value of this approach increases substantially as the number of caves that can act as climate proxies increases.

It is not a simple task. Because each cave is unique, the scientists have to study it for several years before they understand it well enough to use it as a proxy. For example, they must establish how long it takes water to move from the surface down to the cave, a factor that can vary from days to months.

Efforts to use the mineral deposits in caves as climate proxies began in the 1990’s. Currently, there are only a few dozen scientists who are pursuing this line of research and they have analyzed the mineral deposits from 100 to 200 caves in this fashion.

Announcing “Disastersand Ecosystems: Resilience in a Changing Climate”

Announcing “Disastersand Ecosystems: Resilience in a Changing Climate”, a new Massive Open OnlineCourse (MOOC) to be launched on 12 January, 2015

What we all know is that disasters are increasing worldwide. Population growth,environmental degradation and climate change will likely exacerbate disasterimpacts in many regions of the world. What role do ecosystems play in reducingdisaster risks and adapting to climate change? This is the topic of an exciting new Massive Open Online Course thatwill go live in January 2015. It was developedjointly by the United Nations Environment Programme (UNEP), the Center for NaturalResources and Development (CNRD) and the Cologne University of Applied Sciences(CUAS), Germany. This is UNEP’s first MOOC, developed through its engagement with universities worldwide including the Global Universities Partnership on Environment for Sustainability (GUPES).

The MOOC covers a broad range of topics from disastermanagement, climate change, ecosystem management and community resilience. Howthese issues are linked and how well-managed ecosystems enhance resilience to naturaldisasters and climate change impacts are the core theme of the course.
The MOOC is designed at two levels: the leadership track, with the first 6 units providing generalintroduction to the fundamental concepts, which is suitable for people from allbackgrounds who wish to have a basic undertaking of the topic. The second level, or expert track comprises 15 units with more in depth learning on thevarious tools of ecosystem-based disaster risk reduction and climate changeadaptation.
The course is delivered by both scientists and practitioners.In addition there are guest lectures from global leaders and experts, such as Achim Steiner, the Executive Director of the United Nations Environment Programme, Julia Marton-Lefèvre, former Director General of the International Union for the Conservationof Nature (IUCN), Rajendra Pachauri of Teri University and Margareta Wahlströmof the UN International Strategy on Disaster Reduction (UNISDR).

Students will have the opportunity to enhance their knowledgethrough quizzes, real life and fictitious problem-solving exercises, additionalreading materials, videos and a discussion forum. An Expert-of-the-Week will be available torespond to questions and interact with students. Students will receive weeklynewsletters with up-to-date news on ecosystem-based disaster risk reduction andadaptation.
The course is invaluable for universities around the world,where faculty members can use it to update their curriculum and use thelectures and teaching materials for blended learning for their own courses. Atthe same time, the MOOC format also allows those currently outside theuniversity system to learn about the new developments in the area of disastersand climate change, without having to enroll in a university or pay for anonline course. Those who successfully complete the course will be provided witha course certificate.

Ebola and Climate Change: ‘We Are Running Out of Time,’ says World Bank President

Not acting on climate change could have the same results as the inaction on Ebola with significant human and economic impact, warned World Bank Group president Jim Yong Kim in a speech Friday to the International Monetary Fund/World Bank Group annual meeting. He said that addressing both would further the World Bank’s goal of ending extreme poverty by 2030.

Jim Yong Kim President World Bank

“In a world where natural disasters, conflict, financial shocks and epidemics are becoming more frequent and destructive, we at the World Bank Group must do everything we can to become even more relevant,” he said. “Indeed, we’ve been fully engaged lately in fighting two of these global threats: the Ebola epidemic and climate change.”

Ebola and climate change have a few things in common,” he said. “Most importantly, we are running out of time to find solutions to both. Also, until very recently, the plans to fight them were either nonexistent or inadequate. And inaction is literally killing people–one because of the rapid spread of a deadly virus, the other from the poisoning of the atmosphere and the oceans. And finally, perhaps most critically from our point of view, resolving these problems is essential to development, whether from the perspective of human suffering, economic growth or public health.”

Kim, an infectious disease physician, called the initial global response to Ebola “inadequate and slow” but said “Once engaged, we’ve moved with creativity, speed and purpose.” He said that the World Bank’s world on climate change over the last two years provided a blueprint for its response to Ebola.

“Soon after I started at the World Bank [July 2012], I asked my team a simple question: What’s the plan to fight climate change?” he said. “The responses received from our staff and even from leaders in the climate change community were mostly tactical: new technologies here, some efficiencies there. While important, they were not equal to the challenge of keeping a global increase in temperature below 2 degrees Celsius. So, working with others, we developed our own strategy that we hoped could take us a long way toward achieving this objective.”

That five-part plan including carbon pricing, eliminating fossil fuel subsidies, building cleaner cities, encouraging climate-friendly agriculture, and investing in renewable energy sources. He described in detail the World Bank’s campaign on carbon pricing: building a coalition of cooperating governments and businesses.

“At the start of the campaign, we counted 22 countries that would support this goal,” said Kim. “With lobbying, the number kept climbing. Less than a week before the deadline, China, the world’s largest emitter of carbon dioxide, agreed to support carbon pricing. It became the 54th country to endorse the statement. In the four days before the [UN Climate] summit, 20 more countries signed on. At the time of the announcement, 74 governments and more than 1,000 companies and investors had agreed to put a price on carbon. Together, the countries account for up to 54 percent of the world’s carbon emissions, 52 percent of the world’s GDP and nearly 50 percent of the world’s population.”

“Later today, ministers, CEOs and the World Bank Climate Group will join me to turn this pledge into action,” he said.

“We must maintain this commitment because increasing global fragility and volatility will challenge us more and more every day,” he concluded. “In our march to end extreme poverty, conflict, typhoons, floods, droughts, financial shocks and epidemics may at times slow us. But they will not stop us. The Bank will be aggressive and creative and apply large-scale solutions to help states manage, prepare for, recover from and conquer these risks, so they can grow and flourish.” More

Explaining Extreme Events of 2013

A report released today investigates the causes of a wide variety of extreme weather and climate events from around the world in 2013. Published by the Bulletin of the American Meteorological Society, "Explaining Extreme Events of 2013 from a Climate Perspective (link is external)" addresses the causes of 16 individual extreme events that occurred on four continents in 2013. NOAA scientists served as three of the four lead editors on the report.

Of the five heat waves studied in the report, human-caused climate change was found to have clearly increased the severity and likelihood of those events. On the other hand, for other events examined like droughts, heavy rain events, and storms, fingerprinting the influence of human activity was more challenging. Human influence on these kinds of events—primarily through the burning of fossil fuels—was sometimes evident, but often less clear, suggesting natural factors played a far more dominant role.

"This annual report contributes to a growing field of science which helps communities, businesses and nations alike understand the impacts of natural and human-caused climate change," said Thomas R. Karl, L.H.D., director of NOAA’s National Climatic Data Center. "The science remains challenging, but the environmental intelligence it yields to decision makers is invaluable and the demand is ever-growing."

Confidence in the role of climate change about any one event is increased when multiple groups using independent methods come to similar conclusions. For example, in this report, five independent research teams looked at specific factors related to the record heat in Australia in 2013. Each consistently found that human-caused climate change increased the likelihood and severity of that event. However, for the California drought, which was investigated by three teams from the United States, human factors were found not to have influenced the lack of rainfall. One team found evidence that atmospheric pressure patterns increased due to human causes, but the influence on the California drought remains uncertain.

When human influence for an event cannot be conclusively identified with the scientific tools available today, this means that if there is a human contribution, it cannot be distinguished from natural climate variability.

"There is great scientific value in having multiple studies analyze the same extreme event to determine the underlying factors that may have influenced it," said Stephanie C. Herring, PhD, lead editor for the report at NOAA’s National Climatic Data Center. "Results from this report not only add to our body of knowledge about what drives extreme events, but what the odds are of these events happening again—and to what severity."

The report was edited by Herring, along with Martin P. Hoerling, NOAA’s Earth System Research Laboratory; Thomas Peterson, NOAA’s National Climatic Data Center, and Peter A. Stott, UK Met Office Hadley Centre and written by 92 scientists from 14 countries. View the full report online (link is external).
