The $50 billion plan to save Louisiana's wetlands

The oceans are acidifying at an alarming rate due to human-influenced climate change, and the effects are proving detrimental to our food chain and the marine ecosystem - especially shellfish, which are literally crumbling due to the increased levels of carbon dioxide. But shellfish farmers, governments, and scientists are striving to respond with a variety of solutions that vary from the short-term, such as altering methods for growing shellfish for improved harvest, to the bigger picture, seeking ways to decrease CO2 emissions on a global scale.

The degradation of peatlands is a public health and climate change issue. Organizations in Indonesia are working to understand these wetlands better by mapping the location of them throughout the country and around the world. By creating a comprehensive picture of peatlands, which contribute up to 10 percent of global anthropogenic greenhouse gas emissions, key partners can understand how to prevent carbon emitting from the wetlands into the atmosphere.

The world's oceans absorb carbon dioxide from the atmosphere, which is a positive thing in the face of climate change for those living on land, but can harm the animals that rely on certain acidification levels of ocean waters. When it became apparent off the coasts of Oregon and Washington that oysters and other sea life with a shell or a skeleton were suffering the ramifications, researchers created a sensor that could detect acidification levels that could warn oyster growers of potentially harmful areas.

In Australia, the Murray-Darling Basin Ministerial Council was formed after a severe drought to bring together federal, state and regional governments and bridge parochial concerns. It was meant to manage the basin as a whole and end overuse and salinization of farm land, leveraging new technologies to adapt to new realities.

The World Conservation Union estimates that 40 percent of the more than 40,000 species it tracks on its Red List are close to extinction and this problem requires humans to change their behavior to fix it. Rare’s the Pride Campaign uses social marketing to attract attention and communicate the conservation message between local communities and government entities. The Pride Campaign has been replicated around the world for different conservation efforts to protect biodiversity.

Instead of building hard seawalls to protect communities from hurricanes, some are turning to “living shorelines.” These are made out of crushed rock or oyster shells that are placed offshore in front of a wetland. There are more than 120 of these types of habitats — including in Beaufort, North Carolina — and they have shown that they can absorb 50 percent of wave energy, which can reduce the risk of loss of human life and property from flooding. This might not work for all coastal communities, but living shorelines are cheaper than the traditional seawalls.

The burning of coal for fuel is one of the world's largest contributors to CO2 emissions, and continues to worsen the detrimental effects of planetary warming. But while many feel hopeless in light of an administration that denies climate change and the billion-dollar companies that continue full steam ahead with mining and burning coal, a few clever individuals present a simple and straightforward solution: buy up the coal while it's still in the ground, and pay the government to keep it there.

Climate change is a growing issue, but the Citizens' Climate Lobby (a group of volunteers who work to get Republicans and Democrats to work in unison) is aiming to curb carbon emissions. So far the group has had a large increase in number of volunteers and politicians joining and willing to work together.

A collaborative effort among the United Nations' District Energy in Cities Initiative, the Malaysian government, and private partners has facilitated planning in Malaysia's rapidly developing southern state of Johor for a "District Energy System": a single heating and cooling network which decreases energy consumption by converting waste heat from large power stations. Because of this intervention, Iskandar is projected to decrease its energy use by almost 40% -- all while saving money on energy costs, recycling heat energy, and contributing to the nation's goals under the international Paris Accord.

In the face of the global climate crisis, conservative politicians and energy leaders in the US are an unlikely source for climate action. Through the promotion of a carbon tax, in which each ton of emissions gets taxed, these leaders are jumpstarting new forms of climate response. While some are hesitant towards both their support and the logistics of the tax, it may appear the best hope for climate action in the current political climate.
