Although some early efforts to use solar panels to fly around the world have had success, we are still decades away from commercial flights running on solar energy. The cost of utility-scale solar panels has fallen 73% since 2010, for example, making solar energy the cheapest source of electricity for many households in Latin America, Asia and Africa. In the UK, onshore wind and solar are competitive with gas and by 2025 will be the cheapest source of electricity generation.
Now that it has formally assumed the G20 presidency, India should establish an independent review of the G20 debt agenda and make recommendations for reform. Highly-indebted countries, which typically have no voice at G20 summits, must be part of the process, too. The world’s wealthiest countries should seriously consider supporting it.

Secondly, we feed them with other potential sources of food, like maize and soy, which makes for a very inefficient process. And finally, they also require lots of water, fertilisers that can release greenhouse gases, and plenty of land – some of which come from cleared forests, another source of carbon emissions. So, replace your incandescent bulbs with more efficient LEDs, which now come in all shapes and sizes.
Even parking your car andriding a bikethe rest of the way to your destination can save fossil fuel emissions and introduce some exercise to your day. A 2015 study by the Institute of Transportation Studies at UC Davis found that adramatic global increase in bicyclingcould reduce urban transportation emissions up to 10 percent by 2050. For a whole-house systems approach, use the ENERGY STAR Home Advisor tool orHome Performance with ENERGY STAR. Also, consider other improvements such as rooftop gardens, cool roofs, andsustainable landscaping.
Take a close look at the biggest energy hogs in your home.
These adaptation options can be further divided into hard and soft. Hard adaptation relies mostly on capital-intensive human-built infrastructure and involves large-scale changes to human societies and ecological systems. Soft adaptation involves strengthening natural defenses and adaptation strategies in local communities and the use of simple and modular technology, which can be locally owned. The two types of adaptation might be complementary or mutually exclusive.
Others have suggested that certain forms of gender inequity should be addressed at the same time; for example women may have participation in decision-making, or be constrained by lower levels of education. Promoting free trade – e.g., through the removal of international trade barriers – could enhance adaptive capacity and contribute to economic growth. Let industry know you care about climate change by meeting with your bank or investment adviser to make sure your investments do not include fossil fuels. And make sure your workplace, pension fund, university or bank doesn’t invest in fossil fuels either.
Use water efficiently
Scaling that process up to a power plant and building plants big enough cover a significant chunk of the world's growing electricity demand would take momentous efforts requiring materials, land and clear regulations for industry. Politicians supporting the existing fuels and infrastructure may be resistant to rapid change. Besides vastly ramping up the energy from fusion reactions, scientists need to produce them multiple times per second on a constant basis.
If you simply can’t make every change that’s needed, consider offsetting your emissions with a trusted green project – not a ‘get out of jail free card’, but another resource in your toolbox to compensate that unavoidable flight or car trip. The UN Climate Convention keeps aportfolio of dozens of projects around the world you can contribute to. To find out how many emissions you need to ‘buy’ back, you can use its handy carbon footprint calculator. One 2017 study co-authored by Lund University’s Nicholas ranked 148 individual actions on climate change according to their impact. Going car-free was the number-one most effective action an individual could take (except not having kids – but more on that on that later). Cars are more polluting compared to other means of transportation like walking, biking or using public transport.
U.S. reaches a fusion power milestone. Will it be enough to save the planet?
Vote for leaders at all levels of government who take climate change seriously. They should commit to setting science-based targets to reduce harmful carbon emissions, implementing clear plans to reach those targets, adapting to climate change and shifting to a clean-energy economy. The largest source of greenhouse gas emissions come from fossil fuels. Divesting means taking your money out of institutions that fund fossil fuel expansion, which could eventually dry up funding to those projects. So far, the fossil fuel divestment movement has removed $9.94 trillion dollars from fossil fuel companies because of institutional divestments and $5.2 billion thanks to 58,000 individual divestments. The international community must avoid repeating the mistakes of previous debt crises.
The wind energy produced in Denmark, for example, provides about 10 percent of the country's total energy needs. These methods of energy production emit no greenhouse gases once they are up and running. This vulnerability was judged to have contributed to Africa's weak adaptive capacity, resulting in Africa having high vulnerability to future climate change.
More than half the electricity in the United States comes from polluting coal-fired power plants. And power plants are the single largest source of heat-trapping gas. Fortunately, the use of alternative energy sources, such as solar, wind, geothermal, and hydro energy, is gaining increased support worldwide.
Using solar powered garden lights, or switching your outdoor lightbulbs to energy efficient ones is an often overlooked way to cut your energy consumption. Also, avoid power tools and opt for human-powered where you can. Seek out sustainable labels and use rental services for special occasions rather than buying new items that will only be worn once. Lobby local politicians and businesses to support efforts to cut emissions and reduce carbon pollution.#ActNow Speak Uphas sections on political pressure and corporate action - and Count Us In also hassome handy tipsfor how to do this. Pick an environmental issue you care about, decide on a specific request for change and then try to arrange a meeting with your local representative. It might seem intimidating but your voice deserves to be heard.
According to Project Drawdown, universal adoption of LEDs could prevent 7.8 gigatons of carbon emissions. Take advantage of the free home energy audits offered by many utilities. Simple measures, such as installing a programmable thermostat to replace your old dial unit or sealing and insulating heating and cooling ducts, can each reduce a typical family's carbon dioxide emissions by about 5 percent. Replacing single-paned windows with dual-paned windows and installing insulated doors will also greatly reduce heat loss from your home. Research has shown that widespread adoption of vegetarian or vegan diets could lower carbon emissions by 63% and 70% respectively.
If any of these appliances are old, they're probably a lot less efficient than the latest technology. Homes and commercial buildings account for about a third of the country's greenhouse gas emissions, because it takes energy to heat and cool them and to power all the gadgets we've got plugged in. Much of that energy, whether it's electricity from a power plant far away or heat from a gas furnace in your basement, comes from burning fossil fuels, which releases greenhouse gases. When food waste goes to landfill it rots and produces methane, a greenhouse gas with a 100-year global warming potential of up to 34 times that of carbon dioxide. At the 2009 Copenhagen Summit, nations committed to the goal of sending $100 billion per year to developing countries for climate change mitigation and adaptation by 2020.
Adaptations at one scale can also create externalities at another by reducing the adaptive capacity of other actors. This is often the case when broad assessments of the costs and benefits of adaptation are examined at smaller scales and it is possible to see that whilst the adaptation may benefit some actors, it has a negative effect on others. Within the Antarctic and Arctic, at localities where water was close to melting point, socioeconomic systems were particularly vulnerable to climate change. Migration events are multi-causal, with the environment being just a factor amongst many.
To this end the UN is running a partnership titled "Climate Risk and Early Warning Systems" to aid high risk countries with neglected warning systems in developing them. In general higher levels of development mean higher adaptive capacity, but some development locks people in to certain patterns or behaviors. And the most developed areas may have low adaptation capacity to new types of natural hazards, not previously experienced, relative to more familiar natural hazards. The economic costs of adaptation to climate change are likely to cost billions of dollars annually for the next several decades. Reducing, reusing, and recycling in your home helps conserve energy and reduces pollution and greenhouse gas emissions from resource extraction, manufacturing, and disposal.
