In higher-income regions, major interventions are needed at the retail and consumer levels. school (see #6). For individuals to give up meat in favor of options lower on the food chain, those options should be available, visible, and tempting. New uniform, science-based guidance on cover crop management helps producers prevent erosion, improve soil properties, supply nutrients to crops, suppress weeds, improve soil water content, and break pest cycles. Fixing problems related to climate change will likely require a wide range of solutions. In addition, agricultural land use and associated energy consumption to grow livestock feed produce carbon dioxide emissions, while manure and fertilizers emit nitrous oxide. “That speaks to the fact that [climate change] is the defining challenge for that generation.”, “We have to reach a point in which a critical mass, or a tipping point, is reached so that societies in the U.S. and around the world demand their government’s attention to this.”–Cary Coglianese. This is based on the United States. The second is to inform public policy and the changes that would be necessary at all levels of government. In a median time of 66 years, tropical forests can recover 90 percent of the biomass that old-growth landscapes contain. When these areas are disturbed, carbon is released. Education also shores up resilience to climate change impacts. Ranking: Recycling is #70, with 0.90 gigatons of CO2-equivalent reduced. The 2014 New York Declaration on Forests affirmed that aim and added a cumulative target of 865 million acres restored globally by 2030. HFC substitutes are already on the market, including natural refrigerants such as propane and ammonia. After being carefully removed and stored, refrigerants can be purified for reuse or transformed into other chemicals that do not cause warming. Once blanketing 12 percent of the world’s land masses, they now cover just five percent. Solutions in progress: Today, 314,000 wind turbines supply 3.7 percent of global electricity. They have lower incidence of HIV/AIDS and malaria. GHG reduction (Drawdown Scenario—requires greater refrigerant management): 96.49 gigatons of reduced CO2-e by 2050. All materials copyright of the Wharton School of the University of Pennsylvania. (See #6 for statistics on per capita emissions.) The opportunities are enormous, and the majority of it lies in tropical regions. Cost (Plausible Scenario): $41.6 billion net cost. Energy storage and more flexible grids that can manage the variability of production from PV farms will also be integral to solar’s success. Because educating girls (#6) has an important impact on family planning, Project Drawdown allocated 50 percent of total potential Refrigerants, specifically chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), were once key culprits in depleting the stratospheric ozone layer, which is essential for absorbing the sun’s ultraviolet radiation. In simpler words, climate change is the change in weather patterns which can last for extended period of time, even millions of years. Though not focused on safety, these markers often confuse consumers about expiration. Work to be done: See #8 “Solar Farms.”. Compared to rooftop solar, solar farms enjoy lower installation costs per watt, and their efficacy in translating sunlight into electricity is higher. Critics argue that turbines are noisy, aesthetically unpleasant, and at times deadly to bats and migrating birds. Similarly, consumers spurn imperfect spuds in the produce section, overestimate how many meals they will cook in a week, toss out milk that has not gone bad, or forget about leftover lasagna in the back of the fridge. If the world reduces its food waste by 2050, it would see the following: GHG reduction (Plausible Scenario): 70.53 GT of reduced CO2-e by 2050. GoodWeave rescues child weavers from carpet looms in Despite challenging global politics, they reached a remarkable agreement. It will soon be much more. The problem: A third of the food raised or prepared does not make it from farm or factory to fork. Change included access to reproductive health services in its 2014 synthesis report and pointed to population growth as an important factor in greenhouse-gas concentrations. The Knowledge@Wharton radio show on SiriusXM discussed some of the climate change solutions and major takeaways from the Penn report with Cary Coglianese, Penn law professor and political science professor and director of the Penn Program on Regulation; Steven O. Kimbrough, Wharton professor of operations, information and decisions, and Carolyn Kousky, executive director at the Wharton Risk Management and Decision Processes Center. But the data had some surprises in store. They are more empowered at home, at work, and in society. Loosely defined, climate is the average weather at a distinct place that incorporates temperature, precipitation, and … If all nations adopted a similar rate and achieved 100 percent enrollment of girls in primary and secondary school by 2050, there would be 843 million fewer people worldwide than if current enrollment rates sustain. They can be created by planting trees in open pasture, letting those that sprout mature, or by thinning a woodland or plantation canopy to allow for forage growth. That is why, as solar generation continues to grow, so should complementary renewables that are constant, such as geothermal, and that have rhythms different from the sun, such as wind, which tends to pick up at night. Below are the top ten solutions, ranked in terms of emissions reduction potential over a 30-year period. According to the Brookings Institution, “The difference between a woman with no years of schooling and with 12 years of schooling is almost four to five children per woman.” Women with more years of education have fewer, healthier children and actively manage their own reproductive health. As the impacts of global warming progress, silvopasture can help farmers and their livestock adapt to erratic weather. Energy, building, mobility and planning solutions and innovations in cities have the potential to deliver major emission cuts. For example, establish schools in refugee camps. 1 “We need to think about ways of capturing the carbon, either at the source or through forestation or other ways of sequestering the carbon,” Coglianese said. Knowledge@Wharton. Literature Cited. Even as the world continues to spew more carbon pollution, change has begun—and is accelerating Utility-scale solar is currently 0.4 percent of global electricity generation. Soil is the other essential component—and key to the potential silvopasture has for mitigating climate change. The project is ongoing, and plans are to publish more proposals as participants identify newer solutions to combat climate change. top 100 climate-change solutions. Climate change affects all regions around the world. When we lose forests, primarily to agricultural expansion or human settlement, carbon dioxide discharges into the atmosphere. On that last aspect, Coglianese called attention to a paper by Eric Orts, Wharton professor of legal studies and business ethics and faculty director of the Initiative for Global Environmental Leadership. GHG reduction (Drawdown Scenario—requires higher rate of adoption): 47.5 GT of reduced CO2-e by 2050.. So-called geoengineering, radical interventions to either block sunlight or reduce greenhouse gases, is a potential last resort for addressing the challenge of climate change. Radical change from one state, or even the whole United States, won’t address climate change on its own, but taking these actions could help start the planet down a … Because educating girls has an important impact on family planning (#7), Project Drawdown allocated 50 percent of total potential emissions reduction to each solution. The Penn project brings to bear cross-functional skills from across the university, noted Coglianese. The fundamental need is for a “normative change” where society as a whole makes it abundantly clear that climate change is unacceptable, according to Coglianese. Climate change, the periodic modification of Earth’s climate caused by atmospheric changes and the atmosphere’s interactions with geologic, chemical, biological, and geographic factors.
