global Warming And the Absolutely important questions
What is global warming?
A: Below is a simple definition of global warming. (And yes, it happens.) Over the past 50 years, the average global temperature has increased at the fastest rate in recorded history. Experts say the trend is accelerating: all sixteen hotter years have occurred in NASA's 134-year history since 2000 except for one year.Climate change deniers have argued that there has been a "pause" or "slowdown" in heating, but several recent studies, including a paper published in 2015 within the journal Science, have refuted this claim. Unless global warming emissions are limited, scientists say, average temperatures in the United States can increase by up to 10 degrees Fahrenheit in the next century.
Q: What causes global warming?
A: heating occurs when CO2 (CO2) and other air pollutants and greenhouse gases accumulate within the atmosphere and absorb sunlight and radiation that has bounced off the surface. This radiation emerges into space - but these pollutants, which may persist for years to centuries within the atmosphere, trap heat and prompt the earth to warm. This is known as the greenhouse effect.In the United States, burning fossil fuels to produce electricity is the largest source of heat pollution, producing about two billion tons of carbon dioxide each year. Coal-fired power plants are by far the largest polluter.
The transportation sector is the second-largest source of carbon pollution in the country, producing around 1.7 billion tons of carbon dioxide emissions annually.
Reducing serious climate change requires very deep emissions reductions, as well as the use of fossil fuel alternatives worldwide. The good news is that we have started a transformation: US CO2 emissions have decreased from 2005 to 2014 thanks in part to new energy-saving technology and the use of cleaner fuels.
Q: How does global warming relate to extreme weather?
A: Scientists agree that global warming feeds longer and hotter heat waves, more frequent droughts, torrential rains, and more powerful hurricanes. In 2015, for example, scientists said that California's persistent drought - the state's worst water shortage in 1,200 years - was intensified by 15 to 20 percent due to global warming. They also said that the likelihood of similar droughts in the future almost doubled over the past century. In 2016, the National Academies of Science, Engineering, and Medicine announced that it's now possible to confidently attribute some weather events, like some heat waves, to climate change.
Earth's ocean temperatures are getting hotter as well, which means that tropical storms can pick up more energy. So global warming could transform, for example, a Category 3 storm into a Category 4 storm more serious. Scientists have found that the frequency of hurricanes in the North Atlantic has increased since the early 1980s, as well as the number of storms that reached categories 4 and 5. In 2005, Hurricane Katrina - the most severe hurricane in US history - struck New Orleans; the second most expensive hurricane, Sandy, struck the east coast in 2012.
The effects of global warming are felt throughout the world. Extreme heatwaves have caused tens of thousands of deaths worldwide in recent years. In a worrying sign of upcoming events, Antarctica has lost about 134 billion metric tons of ice annually since 2002. This rate could accelerate if we continue to burn fossil fuels at the current speed, some experts say and causing sea levels to rise several meters over a while. The next 50 to 150 years.
Q: What are the opposite effects of worldwide warming?
A: annually, scientists learn more about the results of worldwide warming, and lots of agree that environmental, economic, and health consequences are likely to occur if current trends continue. Here’s just a smattering of what we will anticipate: Dissolving glaciers, early snowmelt, and critical droughts will create more dramatic water deficiencies and enhance the danger of wildfires in the American West. Rising sea levels will cause coastal flooding on the Eastern Seaboard, especially in Florida, and in other areas like the Gulf of Mexico.Forests, farms, and cities will face disturbing new bugs, heat streams, heavy storms, and increased flooding. All these factors will destroy or damage farming and fisheries. Separation of habitats like coral reefs and Alpine meadows could drive many plant and animal species to extinction. Allergies, asthma, and communicable disease outbreaks will become more common thanks to increased growth of pollen-producing ragweed, higher levels of pollution, and therefore the spread of conditions favorable to pathogens and mosquitoes.
Q: Where do we substitute terms of global-warming contributors?
A: In current years, China has become the lead in global-warming contamination, giving about 28 percent of all CO2 emissions.The United States reports in second. Despite making up just 4 percent of the world’s population, we produce a whopping 16 percent of all global CO2 emissions—as very much like the ECU Union and India (third and fourth place) combined. And America remains favorite, by far, in cumulative emissions over the past 150 years.
Our responsibility matters to other countries, and it should interest us, too. While there's little the talk that excess CO2 within the industrial era has mostly come from burning fossil fuels, the longer-term strength of land and ocean carbon sinks is an area of study.
Q: Is that us doing anything to stop global warming?
A: We’ve started. But to avoid the worst effects of global climate change, we'd like to try tons more—together with other countries—to reduce our dependence on fossil fuels and begin using clean energy instead. In 2015, the U.S. EPA promised to reduce carbon pollution from our power plants by approximately a third by 2030, relative to 2005 levels, through its Clean Power Plan. But fast-forward to 2017, and under the Trump Administration, the EPA proposed repealing this critical tool for curbing global climate change. Likewise, while under the Obama administration, the U.S. Department of Transportation proposed carbon pollution and fuel economy standards intended to chop emissions through the 2020s, under the Trump administration, the DOT is functioning to roll back those clean vehicle guards that guard the climate and our health.Fortunately, state leaders—including in-car country itself—recognize that clean transportation must remain a priority if we are to deal with the costly risks of global climate change and protect public health. And regional efforts around the country are helping to spice up the electric car market, which saw a rise in sales for 2017 over 2016. Our clean power economy is improving too, despite governmental efforts to derail it. In 2016, the wind profession grew by 32 percent and solar jobs rose by 25 percent.
Globally, at the United Nations Conference on global weather difference in Paris, 195 countries including us, at the time, admitted to pollution-cutting provisions to prevent the quality global temperature from rising quite 1.5 degrees Celsius above preindustrial times.
To help achieve the deal, the Obama administration has pledged $ 3 billion to the Green Climate Fund, an international organization dedicated to helping poor countries adopt cleaner energy technologies. Under the terms of the Paris agreement, participating countries will meet every five years, starting in 2020, to review their plans to cut carbon dioxide emissions. Starting in 2023, they will also have to report their progress publicly. In 2017, President Trump announced the country's withdrawal from the Paris climate agreement and the elimination of "harmful and unnecessary policies such as the climate action plan," without which the Americans would step forward. Through initiatives such as the United States Climate Alliance and the regional greenhouse gas initiative, we are still at home, and climate mayors, business leaders, companies, and local leaders have pledged to respect and adhere to the Paris Agreement goals. More than 25 cities in 17 states, with a population of more than 5 million, have adopted decisions enabling them to get 100 percent of electricity from renewable sources such as wind and solar energy. Even better, a new initiative by former New York City Mayor Michael Bloomberg is giving the urban class this boost.
The mayors of 100 of the country's most populous cities have been asked to share their plans to make their buildings and transportation systems operate in a cleaner and more efficient manner. The 20 countries with the greatest potential to reduce serious carbon pollution leading to climate change will contribute a total of $ 70 million to the technical assistance provided by Bloomberg Philanthropies and partners.
Q: Is global warming a very big problem for me to help tackle?
A: Wondering how to stop global warming?
Reduce your carbon footprint by taking a few easy steps. Make energy conservation part of your daily routine and decisions as a consumer. When buying new appliances like refrigerators, washers, and dryers, search for products that are tagged with the govt. Energy Star; It meets higher energy efficiency standards than minimum federal requirements. When buying a car, find a car with the highest gas mileage and lowest emissions. You can also reduce your emissions by public transport or car use when possible.
While federal and new state standards are a step in the right direction, much remains to be done. Express your support for climate-friendly preparedness policies to confront climate change, and tell your representatives that the transition from dirty fossil fuels to clean energy should be a top priority - because it is vital to building healthier and safer societies.
The Economic sectors with more greenhouse emission contributions have a greater stake in global climate change policies.
