Answer:
Global warming occurs when carbon dioxide (CO2) and other air pollutants collect in the atmosphere 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 last for years to centuries in the atmosphere, trap the heat and cause 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 impact is called the greenhouse effect.
Explanation:
Though natural cycles and fluctuations have caused the earth’s climate to change several times over the last 800,000 years, our current era of global 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 largest source of greenhouse gases is transportation (29 percent), followed closely by electricity production (28 percent) and industrial activity (22 percent).
Curbing dangerous climate change requires very deep cuts in emissions, as well as the use of alternatives to fossil fuels worldwide. The good news is that countries around the globe have formally committed—as part of the 2015 Paris Climate Agreement—to lower their emissions by setting new standards and crafting new policies to meet or even exceed those standards. The not-so-good news is that we’re not working fast enough. To avoid the worst impacts of climate change, scientists tell us that we need to reduce global carbon emissions by as much as 40 percent by 2030. For that to happen, the global community must take immediate, concrete steps: to decarbonize electricity generation by equitably transitioning from fossil fuel–based production to renewable energy sources like wind and solar; to electrify our cars and trucks; and to maximize energy efficiency in our buildings, appliances, and industries.
Answer:
What was the Reconstruction era? The Reconstruction era was the period after the American Civil War from 1865 to 1877, during which the United States grappled with the challenges of reintegrating into the Union the states that had seceded and determining the legal status of African Americans.
Explanation:
understand mark me as brainliest
Answer: Sensory memory
Explanation:
Sensory memory is known to be the memory which makes individuals to keep memory of something for a brief time. Thus, it gives comprehensive information about something because the brain unconsciously processes the information and makes a decision to keep it or not to keep it.
Answer:
One drop rule means that if you have a single drop of 'black blood, meaning if any of your ancestors, cousins, and/or parents carried African American genetics, it would make you black. It was a way to segregate the white and black people.
