Question: What is global warming?

Answer:

 Here is a simple definition of global warming. (And yes, it is actually happening.) Over the past 50 years, average global temperatures have increased at the fastest rate in recorded history. And experts see that trend accelerating: All but one of NASA's 134-year record has been one of the 16 hottest years since 2000.

Climate change deniers have argued that rising global temperatures have led to a "stagnation" or "slowdown", but several recent studies have rejected this claim, including a 2015 paper published in the journal Science. And scientists say that unless we curb global-warming emissions, the average American temperature could rise to 10 degrees Fahrenheit by the next century.

Question: What causes global warming?

Answer: 

Global warming occurs when carbon dioxide (CO2) and other air pollutants and greenhouse gases collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the Earth's surface. Normally, this radiation escapes into space - but these pollutants, which can remain in the atmosphere for centuries, trap heat and cause the planet to heat up. This is known as the greenhouse effect.

In the United States, the burning of fossil fuels to create electricity is the largest source of heat-trapped pollution, producing about two billion tons of CO2 every year. Coal-burning power plants are by far the biggest polluters. The second largest source of carbon pollution in the country is the transport sector, which emits about 1.7 billion tonnes of CO2 in a year.

To curb hazardous climate change, very deep reductions in emissions are required, as well as the use of fossil fuels worldwide. The good news is that we've started a change: CO2 emissions actually decreased in the United States from 2005 to 2014, thanks to new, energy-efficient technology and cleaner fuel use. And scientists continue to develop new ways of modernizing power plants, generating cleaner electricity, and burning less petrol. The challenge is to ensure that these solutions are used and widely adopted.

Question: How is global warming related to extreme weather?

Answer: 

Scientists agree that Earth's rising temperatures are experiencing longer and more heat waves, more frequent droughts, heavier rainfall and more powerful storms. In 2015, for example, scientists said the ongoing drought in California - the state's worst water shortage in 1,200 years - was intensified by global warming from 15 percent to 20 percent. He also said that the chances of a similar drought in the future had almost doubled in the last century. And in 2016, the National Academies of Science, Engineering and Medicine announced that it is now possible to believe certain weather events, such as some heat waves, directly to climate change.

Earth's ocean temperatures are also warming, meaning that tropical storms can carry more energy. Therefore global warming can turn a Category 3 hurricane into a dangerous Category 4 hurricane. In fact, scientists have found that the frequency of North Atlantic hurricanes has increased since the 1980s, as well as the number of storms that fall into the 4 and 5 ranges. In 2005, Hurricane Katrina - the most expensive hurricane in American history - New Orleans; Sandy, the second most expensive storm, hit the East Coast in 2012.

The effects of global warming are being felt globally. Extreme heat waves have caused thousands of deaths worldwide in recent years. And in an alarming sign of upcoming events, Antarctica has been losing about 134 billion metric tons of ice per year since 2002. This rate may increase if we continue to burn fossil fuels at our current pace, some experts say, leading to sea level rise. Rise various yards over the next 50 to 150 years.

Question: What are the other effects of global warming?

Answer: 

Each year, scientists learn more about the consequences of global warming, and many believe that if the current trend continues, environmental, economic and health consequences are likely to occur. Here's one thing we can look forward to do:

Melting glaciers, early snowfall and severe drought will cause dramatic water scarcity and increase the risk of wild animals in the American West.

Rising sea water levels will cause coastal flooding on the eastern seaboard, particularly in Florida, and other areas such as the Gulf of Mexico.

The forests, farms and cities will face trouble with new pests, heat waves, heavy drift, and increased flooding. All those factors will harm or destroy agriculture and fisheries.

Disintegration of coral reefs and alpine meadows can cause many plant and animal species to go extinct.

Outbreaks of allergies, asthma and infectious disease will become more common due to increased pollen production, higher levels of air pollution and the spread of favorable conditions for pathogens and mosquitoes.

Question: Where does the United States ( U.S. ) stand in terms of global-warming contributors?

Answer: 

In recent years, China has led to global-warming pollution, which is about 28 percent of all CO2 emissions. The United States comes in second. in spite of making up just 4 % of the world's population, we make 16 % of all global CO2 discharges - as much as the European Union and India (third and fourth places) together. And the US is still number one in cumulative emissions over the last 150 years, by far. Our responsibility matters to other countries, and it also matters to us.

Question: Is America doing anything to stop global warming?

Answer: 

We've started. But to evade the worse effects of climate change, we need to do worse, jointly with other nations, to reduce our dependence on fossil fuels and start using clean energy instead.

In 2015, the US Environmental Protection Agency, through its Clean Energy Plan, resolved to reduce carbon pollution from our power plants by 2030 relative to 2005 levels. But fast forward to 2017, and under the Trump administration, the EPA proposed to repeal this important tool to curb climate change. Similarly, under the Obama administration, the US Department of Transportation proposed emission reductions through 2020 to standards for carbon pollution and fuel economy, under the Trump administration, the DOT is working to roll back those clean vehicle safety measures That protect the climate and our health. .

Fortunately, state leaders — including car countries — believe that clean transportation should be a priority if we overcome the costly risks of climate change and protect public health. And regional efforts across the country are helping boost the electric car market, which saw increased sales in 2017 for more than 2016. Our clean energy economy is also growing, derailed despite federal efforts. In 2016, wind employment increased by 32 percent and solar jobs by 25 percent.

Globally, at the 195-nation United Nations Conference on Climate Change in Paris, the United States, including the United States at the time, agreed to pollution-harvesting provisions that would reduce average global temperatures to more than 1.5 ° C pre-industrial. Was with the goal of stopping the time from growing. . (Scientists say that to avoid catastrophic climate effects, we must stay below two degrees of increase.)

To help with the deal, the Obama administration pledged $ 3 billion to the Green Climate Fund, an international organization dedicated to helping poor countries adopt clean energy technologies. Under the terms of the Paris Agreement, participating nations will meet every five years starting in 2020 to revise their plans for CO2 emissions reductions. Starting in 2023, they must also report publicly their progress.

In 2017, President Trump announced the country to withdraw from the Paris Climate Agreement and eliminate "harmful and unnecessary policies such as the Climate Action Plan", forcing Americans to stay ahead without it. The United States Climate Alliance, Regional Greenhouse Gas Initiative, We Are Still in, and Climate Meyers, through the initiative of state, business and local leaders, have resolved to honor and sustain the goals of the Paris Agreement. In more than 25 cities across 17 states, resolutions with populations of more than 5 million have taken resolutions that will enable them to get 100 percent of their energy as wind and solar.

Even better, a new initiative by former New York City Mayor Michael Bloomberg promotes the urban layer of this movement. He asked the mayors of the 100 most populous cities in the country to share their plans to make their buildings and transportation systems run cleaner and more efficiently. 20 which shows the greatest potential for cutting hazardous carbon pollution, which will be part of a total of $ 70 million in technical support funds provided by Bloomberg philanthropy and partners driving climate change.

Question: Is global warming helpful for me in dealing with a problem?

Answer:

 Wondering how to stop global warming? Reduce your own carbon footprint by following a few easy steps. Make energy a part of your routine and your decisions as a consumer. When you shop for new appliances such as refrigerators, washers and dryers, look for the government's ENERGY STAR labeled products; They meet a higher standard for energy efficiency than the minimum federal requirements. When you buy a car, look for the one with the highest gas mileage and the lowest emissions. When possible you can also reduce your emissions by public transport or carpooling.

And while the new federal and state standards are a step in the right direction, much more needs to be done. Voice your support for climate-friendly and climate-change preparedness policies, and tell your representatives that transitioning from dirty fossil fuels to clean power should be a top priority - because it is critical to building healthier, more secure communities is.

Question: When  did global warming start?

Answer:

The history of the scientific discovery of global warming began in the early 19th century when the first glacial period and other natural developments were found in Pulokal and the natural greenhouse effect was identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could cause climate change. Several other theories of climate change were advanced, including forces ranging from volcanoes to solar variations. Thomas Edison, Introduction to electrical technologies, expressed concern for global warming and sustainable energy support in 1930s. In the 1960s, the warming effect of carbon dioxide gas increased rapidly. Some scientists have also reported that human activities that produce atmospheric aerosols (eg, "pollution") may also have cooling effects.

During the 1970s, scientific opinion favored a rapid warming approach. By the 1990s, as a outcome of optimizations in the loyalty of computer models and experimental work confirming the Milankovich theory of the ice age, a agreement position remained: most of the greenhouse gases involved climate change and human-caused emissions, which were profound Were bringing global warming. Since the 1990s, scientific research on climate change has covered many topics and expanded. Research has expanded our understanding of causal relationships, links with historical data, and the ability to numerically model climate change. Research during this period is summarized in an evaluation report by the Intergovernmental Panel on Climate Change.

Climate change, widely interpreted, is an important and permanent change in the statistical distribution of weather patterns over decades to millions of years. This may be a change in average weather conditions, or in the distribution of weather around average conditions (such as more or less extreme weather events). Climate change is caused by factors such as pelagic operation (eg oceanic circulation), amoebic processes (eg, plants), change in solar radiation received by the Earth, plate architectonics and passionate eruptions, and human-induced changes of the natural world . The latter effect is currently causing global warming, and "climate change" is often used to describe human-specific effects.
