We have the technology and practical solutions at hand.
Solutions Solutions to Global Warming There is no single solution to global warming, which is primarily a problem of too much heat-trapping carbon dioxide CO2methane and nitrous oxide in the atmosphere. Learn more about the causes of global warming.
The technologies and approaches outlined below are all needed to bring down the emissions of these gases by at least 80 percent by mid-century.
To see how they are best deployed in each region of the world, use the menu at left. The energy used to power, heat, and cool our homes, businesses, and industries is the single largest contributor to global warming.
Energy efficiency technologies allow us to use less energy to get the same—or higher—level of production, service, and comfort. This approach has vast potential to save both energy and money, and can be deployed quickly.
A variety of solutions are at hand, including improving efficiency miles per gallon in all modes of transport, switching to low-carbon fuels, and reducing vehicle miles traveled through smart growth and more efficient mass transportation systems. Renewable energy sources such as solar, wind, geothermal and bioenergy are available around the world.
Multiple studies have shown that renewable energy has the technical potential to meet the vast majority of our energy needs. Renewable technologies can be deployed quickly, are increasingly cost-effective, and create jobs while reducing pollution.
Phasing out fossil fuel electricity: Dramatically reducing our use of fossil fuels—especially carbon-intensive coal—is essential to tackle climate change.
There are many ways to begin this process. Key action steps include: While it may sound like science fiction, the technology exists to store carbon emissions underground. The technology has not been deployed on a large scale or proven to be safe and permanent, but it has been demonstrated in other contexts such as oil and natural gas recovery.
Demonstration projects to test the viability and costs of this technology for power plant emissions are worth pursuing. Managing forests and agriculture: We can fight global warming by reducing emissions from deforestation and forest degradation and by making our food production practices more sustainable.
Because nuclear power results in few global warming emissions, an increased share of nuclear power in the energy mix could help reduce global warming—but nuclear technology poses serious threats to our security and, as the accident at the Fukushima Diaichi plant in Japan illustrates to our health and the environment as well.
Developing and deploying new low-carbon and zero-carbon technologies: Research into and development of the next generation of low-carbon technologies will be critical to deep mid-century reductions in global emissions. Current research on battery technology, new materials for solar cells, harnessing energy from novel sources like bacteria and algae, and other innovative areas could provide important breakthroughs.
The countries of the world—from the most to the least developed—vary dramatically in their contributions to the problem of climate change and in their responsibilities and capacities to confront it. A successful global compact on climate change must include financial assistance from richer countries to poorer countries to help make the transition to low-carbon development pathways and to help adapt to the impacts of climate change.
Adapting to changes already underway: As the Climate Hot Map demonstrates, the impacts of a warming world are already being felt by people around the globe. If climate change continues unchecked, these impacts are almost certain to get worse. From sea level rise to heat waves, from extreme weather to disease outbreaks, each unique challenge requires locally-suitable solutions to prepare for and respond to the impacts of global warming.
Unfortunately, those who will be hit hardest and first by the impacts of a changing climate are likely to be the poor and vulnerable, especially those in the least developed countries.
Developed countries must take a leadership role in providing financial and technical help for adaptation. Solutions to Global Warming.The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action should be taken to curb it, and if so what that action should be.
Nov 20, · Global Warming: News, Facts, Causes & Effects. Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a .
Global Warming Is A Serious Issue That Should Have Immediate Attention As Vice President Al Gore has said about the threat of global warming, it is "the most serious problem our civilization faces" (2). May 05, · Global warming and climate change is looked at in this section of the global issues web site.
Introduced are some of the effects of climate change. In addition, this section attempts to provide insights into what governments, companies, international institutions, and other organizations are attempting to do about this issue, as well as the Status: Open.
The global warming debate would not be so heated if it were simply a question of science. Since one side blames mankind for the crisis, they demand immediate action to avoid imminent disaster.
A: In recent years, China has taken the lead in global-warming pollution, producing about 28 percent of all CO2 emissions.
The United States comes in second. The United States comes in second.
