The climate of the eastern Caribbean stretches from the Virgin Islands to Trinidad. And like other tropical regions, it is highly dependent on rainfall for freshwater resources. Yet climate change could throw the current precipitation cycle out of whack. Generally, wet places are projected to get wetter and the dry places drier. NCAR scientist Kevin Trenberth refers to this phenomenon as, “the rich get richer and the poor get poorer.” That raises big questions for the eastern Caribbean.
Everyone on Earth is somehow going to be affected by climate change. Children are extremely vulnerable to climate impacts and they’ll be forced to deal with the long-lasting changes carbon emissions are driving.
From early in the morning on a workday to the wee hours after a party, from my grandmother’s home to one of the world’s finest restaurants, at every Mexican table, corn is king. It’s not just one type of corn, but numerous varieties used for different dishes. Yet climate change could threaten the diversity of maize.
The key to planning is identifying climate trends and impacts and what appropriate preparedness actions we can execute in a timely manner. For weather events like the current trend of rainy afternoons, an appropriate preparedness action would be to keep an umbrella handy. But what can we do for climate events during the hurricane season, for example?
As we enter the second half of 2014, climate forecasters continue to watch the Pacific for the development of an El Niño event. An El Niño Watch has been in place since March, but conditions still have yet to fully develop.
Climate-induced human migration makes a quiet but notable appearance in the third U.S. National Climate Assessment released this May. It comes in chapter 23, in the form of a ‘key message’ to the 100,000 or so atoll inhabitants within the U.S.-affiliated Pacific Islands region:
“Mounting threats to food and water security, infrastructure, and public health and safety are expected to lead to increasing human migration from low to high elevation islands and continental sites.”
Twice a year, delegates from 192 countries, along with a range of non-governmental organizations, news outfits, and for-profit groups under the guise of non-profits, descend on the small German city of Bonn for a session of the United Nations Framework Convention on Climate Change, or UNFCCC.
C+S Co-Director Ben Orlove recently spoke with the Guardian about how to deal with climate change from a business perspective when skeptics are involved. Orlove suggests that many times identity comes into play, especially with so called climate change losers, such as the coal industry. To help, Orlove recommends finding allies who are also fighting […]

Tropical forests have benefits that go beyond carbon sequestration. Despite this, deforestation continues unabated around the world, contributing to massive quantities of carbon emissions. Through her internship at the United Nations Development Programme, C+S student Manishka De Mel is supporting the UN-REDD Programme to review approaches to participatory monitoring – bringing together science and society.
It was around sunrise when I stepped off the turbo-prop airplane’s worn aluminum staircase and into the thick humid air, filled with wood smoke, the smell of burning trash, and the calls of countless roosters. I had no idea what to expect on this, my first day of fieldwork on Flores Island. Flores is one of the more than two thousand islands that make up the region called Nusa Tenggara Timur or NTT for short- a region situated about four hours by air to the east of Jakarta.
Come visit us at Idealist Grad Fairs across the U.S. this fall.
The Indian Monsoon is the primary source of water for approximately one-fourth of the world’s population. Tree-ring data from India’s forests can be a perfect model to peek into the climate of the past and improve predictions for the region in the future.
Yogi Berra was right, the world isn’t perfect, and it never will be. What we love about New York often leaves us open to perils we need to shield ourselves from. Reynir Winnan discusses updating the City’s Hazard Mitigation Plan.
You might ask yourself what plastic bags have to do with climate change. Sofia Martinez explored the connection and worked with the Human Impacts Institute to see if there’s support for a plastic bag ban in New York.
Ministries of agriculture generally want to estimate crop yield to plan for food security and crop exports. Ever wonder how it’s estimated?

By Elisabeth Gawthrop, Climate and Society ’13 For many of us, dust is just an annoyance. It’s the coating that accumulates on our picture frames, and, for some, it may trigger unwelcome allergies. Dust is increasingly garnering interest, however, in the scientific community, including the role it plays in the climate system. And for many in […]
“For me finance is no longer associated with wearing suits and reading the Wall Street Journal.” I am glad my classmate Ricarda Dahlheimer cleared that up for all of us in her post earlier this summer and made the task of describing my summer internship a great deal easier. Since I started my internship at the United Nations Development Program (UNDP) in early June, I have enjoyed the comfort of light summer dresses and not once read the Wall Street Journal. And yet, I work on climate finance.
The Agricultural Model Intercomparison and Improvement Project (AgMIP) is a major international effort linking climate science, agriculture and economics to improve model predictions of global agricultural production and world food security under the conditions of a changing climate.
In Eastern Sudan, where cracking soils and Acacia-Balanites woodlands dot the landscape, there roams a ferocious little female bug whose bite packs a serious punch. The female sand fly, of the genus Phlebotomus, has a terrifying and death delivering parasitic unicellular organism residing within it, Leishmania donovani, responsible for the disease, Visceral Leishmaniasis (VL), affecting people worldwide.
Despite considerable advances in climate modeling, projections can never be certain, but they get the job done anyway.
Meningitis is an infectious disease caused by bacteria Neisseria Meningitides and is transmitted between humans through respiratory droplets or throat secretions. Existing research has confirmed the tie between environmental factors and the transmission risk of meningitis. Such factors include but are not limited to humidity, temperature and wind speed. With infectious diseases being one of the three most challenging climate sensitive health issues, the central question that the environmental science and the health communities both struggle to answer is: how to integrate climate information into public health decision making process?
Tucked away in the corner of the Lamont campus, a lone building is marked only with the words “Tree Ring Lab” in fading white paint on a cross-section of a tree. Although the lab holds an idyllic charm with dendro-chronologists walking barefoot and sipping foreign teas, this is the home to some of the most ground-breaking tree ring research.
Climate change affects the agricultural sector directly, by altering growing seasons through precipitation and temperature changes and increasing the number of extreme events that can destroy whole crops. In an urban environment, however, the effects can be compounded by reliance on the transportation sector to ship in most food items, population density creating high demand in a small region and economic disparity.
One significant effect of climate change is increased climate variability. High temperatures are going to become higher and extremes will be more frequent, dry spells are going to last longer, storms are going to be more intense. Many parts in Africa are already feeling this effect: long dry spells and food shortages are followed by intense storms and flash floods. In Uganda, the Partners for Resilience (PfR) are working to help marginalized communities adapt to this increased variability by implementing early warning systems across timescales.
A “Monsoon” is traditionally defined as a seasonal reversing surface wind and corresponding change in precipitation. Monsoon regions experience a sharp contrast between a wet summer and a dry winter. The Asian monsoon, including regional monsoons over South Asia, East Asia and Northwest Pacific, is one of the major monsoon systems of the world. Since summer monsoon precipitation dominates the total annual precipitation in these regions, analyzing changes to the monsoon has important implications for water resources, agriculture, food security, etc.
In rural Uganda, an evaluation to discover how much a Red Cross project taught communities about climate change and disaster risk reduction instead shows how much there is to learn from these communities.
Climate change has been ascending in the Peruvian environmental public agenda, with greenhouse gas (GHG) mitigation being recognized as an opportunity to address structural issues such as environmental degradation, social conflict, and competitiveness. As one of the fastest growing countries in Latin America, Peru has the opportunity to shape its development model before getting locked-in to a highly emitting, low technology and socially exclusive economy
How hot is too hot? How much does humidity matter? Is a heat wave in May worse than one in August? These are the questions being worked out at the IRI, in pursuit of creating a heat wave map room for the Red Cross/Red Crescent Climate Centre. The questions are deceptively simplistic, but the answers could have major health implications. And they’ve been on the mind of one Climate and Society student every day this summer.
Early Warning Systems based on seasonal climate forecasts together with Early Detection Systems have proved essential to preventing and controlling malaria and cholera outbreaks throughout Sub-Saharan Africa.
The heated debate on climate change often brings into question how much our planet may or may not actually be warming. Are recent heat waves and wild land fires actual phenomena of anthropogenic climate change or are they nothing more than a sporadic event experienced from time to time? And just how accurate is station data utilized to make future projections?
With international policy efforts to limit greenhouse gas emissions stalling over the past two decades, it is an increasingly recognized opinion that climate change adaptation strategies, and the policies that enable them, must be given immediate priority. In contrast to mitigation, adaptation seems in many ways the more straightforward approach to tackling the challenges of climate change, with more attainable goals in the short term.
New York. A torrential downpour. Suddenly, the edges of pavements are gushing rivers. Did you ever stop to think – where does this stormwater go? Alice Cowman has some answers and a look at innovative solutions to ensure cities aren’t swamped.
Seasonal climate forecasts can be integral pieces in natural resource management decisions for Tajikistan, considering its lack of climatic data and vulnerability to climate change.
Can science and social capital go hand in hand? How do we approach climate change without seeming preachy? Is there a way to integrate science into daily social interactions, and if so, how far can it go?
Cities all over the world are getting hotter and more polluted as a result of climate change and urban heat island effect. Is this phenomenon irremediable? Certainly not in view of the burgeoning of innovative adaptation measures across the world.
Creating forecasts and working on climate science in the confines of the lab can sometimes lead to a narrow perspective. C+S student Jack Poberezny takes pause for thought about the other perspectives that might be out there after an article about the issues he’s working on for his summer internship show up on Reddit.
Island systems are on the forefront of global change. Through his internship at the Center for Biodiversity and Conservation, C+S student Nadav Gazit is learning how islands adapt to these changes in a fast-track world.
While the solutions to climate adaptation might seem obvious, figuring out how to successfully implement them is anything but.
Climate change is threating the lives of human beings, wildlife and the ecosystem and its impacts are being felt, expected to get worse and affect the most vulnerable especially children, women and the elderly. Regions with less adaptive capacity such as Africa, Small Island States and also Least Developed Countries will be the hardest hit. Climate finance is needed in order to cope with, adapt and also mitigate changes.
Sarah Abdelrahim found her way from C+S to Nairobi, Kenya. What skills did she gain from the program that are informing her work with the United Nations Environmental Programme? Find out!
Few countries have saved enough pennies for “a rainy day” and even less of those have considered saving for “extreme precipitation” and other impacts associated with climate change. Oftentimes, the bottleneck of building climate resilient communities is financing.
Extreme events often prompt questions that begin with “why?” Why now? Why me? Why here? There is no simple answer to these questions due to the chaotic nature of the climate system. However, part of the answer can be found by examining past climate trends and projections for the future. Events such as Hurricane Sandy cause huge impacts on individuals and the environment. From catastrophes such as these and the questions that follow, an opportunity for conversation is created. One organization that is committed to facilitating that conversation is City Atlas.
Climate and Society students have left the classroom behind and for summer internships. Over the next two months, each student will be sharing their experiences in individual blog posts. Read on for a preview of what to expect!
