How Mexico City's poorest neighbourhood is battling climate change

While some parts of the United States struggle with drought, others are faced with more water than they know what to do with. Minnesota reconstructs roads and drainage systems in order to be more prepared for the large amounts of rain fall they have received, largely due to climate change.

In Oakland, a company created an online crowdfunding platform that allows users to earn interest by financing clean energy projects and gives people with good social intentions a direct line of action. Across the world, there is a growing movement toward people-powered clean energy.

Americans often want to connect to a cause beyond writing a check. Crowdsourcing is creating new forms of philanthropy globally, giving donors more choice and a stronger connection to the projects they fund.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

Louisiana and Vietnam both need affordable solutions to rising sea levels. Leaders from Vietnam visited Louisiana to compare ideas.

Very few people go to city council meetings. MindMixer, a tech startup company, increased civic participation in states across the U.S. with online platforms for city officials and the community to discuss ideas.

Bangladesh is fighting rising sea levels due to climate change. It's doing so with the help of foreign money and Dutch-inspired engineering.

In a country of limited resources — and perhaps for that very reason — preparing for natural disasters is top of the agenda in Bangladesh. Various grassroots, collaborative programs have been put in place over the years to help address many facets of the calamities caused by cyclones, from improved emergency shelters to long-term support for those who lose their livelihoods in the storms.

Summer in the Northwest presents a great risk of wildfires. A pile burning operation, just one facet of the strategy that Oregon has enacted to conserve its forests, clears undergrowth to lessen the risk of mega-fire. The work stimulates the local economy and provides employment, but it's also a very small part of what needs to be done.

After the drought hit Australia in the early 2000s, city officials had to start thinking seriously about ways to conserve and creatively store their water. External tanks became the solution, storing rain runoff to create an available source of water for Melbourne residents. This solution may not fit every location, but there are other teachable lessons such as taking radically shorter showers.
