Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit. Between 1880—the year that accurate recordkeeping began—and 1980, it rose on average by 0.07 degrees Celsius (0.13 degrees Fahrenheit) every 10 years. Since 1981, however, the rate of increase has more than doubled: For the last 40 years, we’ve seen the global annual temperature rise by 0.18 degrees Celsius, or 0.32 degrees Fahrenheit, per decade. The result? A planet that has never been hotter. Nine of the 10 warmest years since 1880 have occurred since 2005—and the 5 warmest years on record have all occurred since 2015. Climate change deniers have argued that there has been a “pause” or a “slowdown” in rising global temperatures, but numerous studies, including a 2018 paper published in the journal Environmental Research Letters, have disproved this claim.

The impacts of global warming are already harming people around the world. Now climate scientists have concluded that we must limit global warming to 1.5 degrees Celsius by 2040 if we are to avoid a future in which everyday life around the world is marked by its worst, most devastating effects: the extreme droughts, wildfires, floods, tropical storms, and other disasters that we refer to collectively as climate change. These effects are felt by all people in one way or another but are experienced most acutely by the underprivileged, the economically marginalized, and people of color, for whom climate change is often a key driver of poverty, displacement, hunger, and social unrest.

Causes of global warming

Global warming happens when carbon dioxide (CO2) and other air pollution gather in the environment and absorb sunlight and solar radiation that have bounced off the earth’s surface. Normally this radiation would escape into space, but these pollutants, which can final for years to centuries in the atmosphere, lure the warmness and reason the planet to get hotter. These heat-trapping pollutants—specifically carbon dioxide, methane, nitrous oxide, water vapor, and synthetic fluorinated gases—are known as greenhouse gases, and their have an impact on is called the greenhouse effect.

Though natural cycles and fluctuations have triggered the earth’s local weather to trade a number of times over the closing 800,000 years, our cutting-edge generation of international warming is directly attributable to human activity—specifically to our burning of fossil fuels such as coal, oil, gasoline, and natural gas, which results in the greenhouse effect. In the United States, the greatest supply of greenhouse gases is transportation (29 percent), observed carefully by way of electrical energy production (28 percent) and industrial undertaking (22 percent).

Curbing dangerous local weather exchange requires very deep cuts in emissions, as properly as the use of selections to fossil fuels worldwide. The correct information is that international locations round the globe have formally committed—as part of the 2015 Paris Climate Agreement—to decrease their emissions through setting new requirements and crafting new insurance policies to meet or even exceed these standards. The not-so-good news is that we’re not working quickly enough. To keep away from the worst influences of climate change, scientists inform us that we need to reduce global carbon emissions by means of as an awful lot as forty percent by means of 2030. For that to happen, the global neighborhood should take immediate, concrete steps: to decarbonize electrical energy generation by means of equitably transitioning from fossil fuel–based production to renewable power sources like wind and solar; to electrify our automobiles and trucks; and to maximize power effectivity in our buildings, appliances, and industries.

Effects of Global Warming

Global warming is anticipated to have far-reaching, long-lasting and, in many cases, devastating penalties for planet Earth. Global warming, the gradual heating of Earth's surface, oceans and atmosphere, is caused with the aid of human activity, specifically the burning of fossil fuels that pump carbon dioxide (CO2), methane and other greenhouse gases into the atmosphere. Despite political controversy about local weather change, a foremost record launched Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC) mentioned that scientists are extra sure than ever of the link between human things to do and international warming. More than 197 international scientific organizations agree that international warming is real and has been precipitated by means of human action. Already, global warming is having a measurable effect on the planet.

"We can examine this taking place in actual time in many places. Ice is melting in both polar ice caps and mountain glaciers. Lakes round the world, which include Lake Superior, are warming rapidly — in some cases faster than the surrounding environment. Animals are altering migration patterns and flora are changing the dates of activity," such as timber budding their leaves beforehand in the spring and losing them later in the fall, Josef Werne, a professor of geology and environmental science at the University of Pittsburgh, instructed Live Science.

Note

Experts confirms that global warming is the major challenge for our global society. There is very little doubt that global warming will change our climate in the next century. So what are the solutions to global warming? First, there must be an international political solution.
