The latest science, described in the World Bank report “Turn Down the Heat,” indicates that we are heading toward a 4° C warmer world, with catastrophic consequences in this century. While carbon dioxide (CO2) is still the No. 1 threat, there is another category of warming agent called short-lived climate pollutants (SLCPs). Mitigating these pollutants is a must if we want to avoid the 4° C warmer future.
The main SLCPs are black carbon, methane, tropospheric ozone, and hydrofluorocarbons. They are potentially responsible for more than one-third of the current warming. Because SLCPs have a much shorter lifetime in the air than CO2; reducing their emissions can create almost immediate reduction of global/regional warming, which is not possible by reducing CO2 emissions alone. According to one U.N. report, full implementation of 16 identified measures to mitigate SLCPs would reduce future global warming by about 0.5˚C.
In this blog, we will focus on one SLCP – black carbon. Black carbon is a primary component of particulate matter (PM), the major environmental cause of premature deaths globally. As a climate pollutant, black carbon’s global warming effects are multi-faceted. It can warm the atmosphere directly by absorbing radiation. When deposited on ice and snow, black carbon reduces their reflecting power and increases their melting rate. At the regional level, it also influences cloud formation and impacts regional circulation and rainfall patterns such as the monsoon in South Asia.
It was heartening to attend the recent Partnership for Market Readiness (PMR) forum at the World Bank, where countries renewed their commitments to testing and piloting market-based instruments for greenhouse gas emission reduction. The PMR is country-led and builds on countries’ own mitigation priorities. Focus is placed on improving a country's technical and institutional capacity for using market instruments to scale up climate change mitigation efforts.
Hot on the heels of Hurricane Sandy, Typhoon Bopha lashed the shores of the Philippines earlier this month, leaving 900 dead and 80,000 homeless. Extreme weather is becoming the norm. The World Bank-commissioned report, “Turn Down the Heat: Why a 4°C Warmer World Must be Avoided” found that scientists are unanimously predicting warming of 4 degrees Celsius by the end of the century. The social, economic, and environmental consequences will be devastating. Over the past 20 years, over half of South Asians – more than 750 million people – have been affected by natural disasters, with the loss of life estimated at more than 60,000, and damages above $45 billion.
For a number of years, a majority of South Asians have been painfully aware that climate change is real and, if left unfettered, has the potential to reverse the significant gains the region has made on poverty reduction and other Millennium Development Goals.
In 2009, the government of the Maldives held a Cabinet meeting underwater to remind the world that the country – which is on average 2.7 meters above sea level – will be completely wiped out if oceans rise.
Nepal’s government held a Cabinet meeting at the base of Mount Everest – at an altitude of 5,242 meters above sea level – to stress that 1.3 billion Asians depend on the seven major rivers with headwaters originating from the vulnerable Himalayan glaciers for their livelihoods.
Farmers in Bangladesh adapting to increased soil salinity and climate change.
Barguna is at the very southern end of Bangladesh and looks nothing like the rest of the country.
Bangladesh is very green – driving through you can see the luxuriant green rice fields stretching out endlessly, the spread interrupted only by clusters of dark trees surrounding a small village, and sometimes by the yellow patches of mustard fields. But Barguna is not green and vibrant - it has now become drab brown.
Stepping onto the soil of Barguna, one is reminded of a parched desert. The ground is rock-hard, cracked and mostly barren. I was careful, threading lightly - afraid of stepping too hard in case the ground suddenly gave away.
The district wasn’t always this desolate. But devastated by repeated cyclones, erratic weather patterns and saline intrusion along the coast, farmers in these coastal communities have seen their lands yield less and less with the passing years.
“I still remember Cyclone Sidr in 2007,” said Hasina Begum, Headmistress of Paschim Napitkhali Primary School in Barguna, Bangladesh.
She fell silent, her face slowly crumpling up - the shadows in her dark eyes gathering into deep pools of sadness.
“There were warnings, but nothing could really prepare us for what happened. Cyclone Sidr hit my hometown, Barguna with ferocious intensity. Powerful gusts of winds and heavy rainfalls frightened the helpless people, many of whom had left their homes and processions to seek the protection of cyclone-shelters, like my school.”
The Paschim Napitkhali Primary School, a non-descript two storied building had played a life-saving role in 2007, when Barguna and other coastal regions were hit hard by the storm surge of over 5 meters (16 ft). Initially established by Hasina’s father, the school was later rebuilt and converted into a school-cum-cyclone-shelter. During the year, the primary school bustles with children – but during cyclones and other natural disasters, the building doubles up as a shelter. In 2007, this cyclone-shelter alone had helped save more than 800 people.
Bangladesh can be described as “ground zero” at the intersection of climate change and food security.
The country is widely recognized as one of the places most vulnerable to the effects of a changing climate, which strains food systems alongside rapidly growing and urbanizing populations. Yet, despite these dual challenges, the World Bank expects Bangladesh will meet its Millennium Development Goal (MDG) of halving the number of people living in extreme poverty by 2015.
Given the impact of the global food crisis and numerous natural disasters, how is Bangladesh managing this feat? And can we map the country’s progress?
This season in Bangladesh marks the 40th anniversary of the 1970 cyclone which ravaged the southern coast and killed over half a million people, decimated the homes of countless families, destroyed millions of livestock, key infrastructure, and damaged productive land. The recent cyclones Sidr in 2007 and Aila in 2008 also claimed the lives of over 3000 people each, leaving millions of poor more vulnerable to climate change than ever before. In the wake of all these cyclones, questions were raised about how to build resilience to climate change impacts without compromising national development goals. Is Bangladesh developing differently? What lessons can be learned from experience of Bangladesh to reframe development and climate action as mutually supportive objectives?
If you were in Bangladesh in June, you would have found teachers in schools, preachers in mosques, and ads in newspapers, television, loudspeakers and pamphlets, encouraging people to bring in their incandescent bulbs to exchange with new Compact Fluorescent Lamps (CFLs) – and encouraged they were! On Saturday, June 19th 2010, at over 1,400 rural and urban distribution centers spread across 27 districts, manned by teachers, utility workers and other volunteers, Bangladeshis collectively took home about five million high quality CFL bulbs, in the first round of distribution.
They broke a record set by the British in January of 2008, for the most number of CFL bulbs distributed in a single day―some 4.5 million. In June, the Government and people of Bangladesh were inspired to do even better … and they did!
