Carbon dioxide is the climate’s worst enemy. Resources are available to help disseminate consistent public health recommendations and evidence-based practices for state, local, territorial and tribal public health organizations, grantees, and practitioners. “Talk to your friends and family, and make sure your representatives are making good decisions,” Haq says. Among the ideas: releasing sulfate particles in the air to mimic the cooling effects of a massive volcanic eruption; placing millions of small mirrors or lenses in space to deflect sunlight; covering portions of the planet with reflective films to bounce sunlight back into space; fertilizing the oceans with iron or other nutrients to enable plankton to absorb more carbon; and increasing cloud cover or the reflectivity of clouds that already form. And citizens of developing nations want and arguably deserve the same comforts, which are largely thanks to the energy stored in such fuels. There are no perfect solutions for reducing dependence on fossil fuels (for example, carbon neutral biofuels can drive up the price of food and lead to forest destruction, and while nuclear power does not emit greenhouse gases, it does produce radioactive waste), but every bit counts. Purchasing energy-efficient gadgets can also save both energy and money—and thus prevent more greenhouse gas emissions. Small steps can add up to big reductions in your electricity use—and your utility bill. Beef production requires 28x more land, 6x more fertilizer, and 11x more water than these other proteins than the calorie-equivalent of pork or chicken, according to a paper published in Proceedings of the National Academy of Sciences. Coal is the substrate, supplying roughly half of the electricity used in the U.S. and nearly that much worldwide—a percentage that is likely to grow, according to the International Energy Agency. It’s responsible for about 20% of global warming, according to National Geographic, and a big portion of methane comes from cows (more on that later). In the most comprehensive report on effective climate solutions, Project Drawdown named educating girls as the #6 most impactful solution (for reference, composting is #60, and rooftop solar is #10). Ten possibilities for staving off catastrophic climate change. It would also take far less land to grow the crops necessary to feed humans than livestock, allowing more room for planting trees. So take shorter showers, turn off the tap while brushing your teeth, and switch to WaterSense-labeled fixtures and appliances. Adopting a sustainable life isn’t easy, especially since it’s difficult to feel that your actions are truly making a difference. Because of a little thing called the drop-in-the-bucket effect (read: “my actions won’t actually make a difference”), 80% of Americans don’t consistently make an effort to live a sustainable life, according to Pew. Oh, wait . Move Closer to Work—Transportation is the second leading source of greenhouse gas emissions in the U.S. (burning a single gallon of gasoline produces 20 pounds of CO2). 2018 was about getting our AI smarter, boosting automation, bringing down loss ratio, and building mad science projects. The Amazon and other forests are not just the lungs of the earth, they may also be humanity's best short-term hope for limiting climate change. Solution to Doom. Here’s what to say to get your friends to exercise their most fundamental freedom, and contribute to the future of our country. The Tempestry Project invites you to spin a colorful yarn about rising temperatures. But it doesn't have to be that way. Here’s how to convince those who don’t. The enormity of global warming can be daunting and dispiriting. Links. Make sure your bank, insurance company, and university (some of the world’s biggest investors in coal) have agreed to divest. The goal is simple. One way to dramatically curtail transportation fuel needs is to move closer to work, use mass transit, or switch to walking, cycling or some other mode of transport that does not require anything other than human energy. 4. (But don’t turn down the heat more than 10 degrees if it’s only for a few hours- it’ll take too much energy to heat back up. Ask your local leaders these five questions. Infrastructure Upgrade—Buildings worldwide contribute around one third of all greenhouse gas emissions (43 percent in the U.S. alone), even though investing in thicker insulation and other cost-effective, temperature-regulating steps can save money in the long run. ), Shore up your windows, seal up the doors, and plug up dafty holes (here’s a comprehensive guide that, Divest your 401k from fossil fuels (you can analyze your stocks on. If they haven’t, call on them to do so. To take but one example, efficient battery chargers could save more than one billion kilowatt-hours of electricity—$100 million at today's electricity prices—and thus prevent the release of more than one million metric tons of greenhouse gases.
