Figure 4: Fingerprints of human-caused global warming.
The science behind global warming is complex. Without question, plants, and natural gas have contributed heavily to GHG pollution, the major cause of global warming. We must unite to shut down these industries. Similarly, consumer overconsumption of fossil fuels represents another big piece of the climate-crisis equation. We absolutely must rethink, retrofit and/or redesign our gas-guzzling cars and our energy-inefficient buildings, if we want to reduce fossil fuel use by 90 percent over the next few decades.
Lets take a look at the major human causes of global warming.
The IPCC stated in a 2013 report that due to human-caused global warming, it is "virtually certain" (99-100% probability) that the upper ocean warmed between 1971 and 2010. An Oct. 2014 study said that the oceans are the "dominant reservoir of heat uptake in the climate system." A separate Oct. 2014 study found that the oceans absorb more than 90% of the heat generated by human-caused global warming. Since 1970 the upper ocean (above 700 meters) has been warming 24-55% faster than previous studies had predicted. A May 2013 study published in found that between 1958-2009 the rates of warming in the lower ocean (below 700m) "appear to be unprecedented." According to an Oct. 2013 study, the middle depths of the Pacific Ocean have warmed "15 times faster in the last 60 years than they did during apparent natural warming cycles in the previous 10,000." Warmer ocean waters can harm coral reefs and impact many species including krill, which are vital to the marine food chain and which reproduce significantly less in warmer water. Warming oceans also contribute to sea level rise due to thermal expansion, and warmer ocean waters can add to the intensity of storm systems.
i think the cause of global warming is the trash we throw out do you know that the fums and STANK of our garbage is also poluting our air and probably twice as bad as the plantations!!!
This category encompasses ice that lasts longer than a year on land, including mountain glaciers, ice caps, ice sheets, and permafrost—most of which are shrinking because of global warming. Discover how .Currently, we are adding greenhouse gases to the atmosphere through the burning of fossil fuels. As more greenhouse gases accumulate in the atmosphere, more heat is being trapped. This causes global warming. Consequently, the fact that carbon dioxide lets sunlight pass freely through the atmosphere is an integral aspect of the greenhouse effect. Carbon dioxide's invisibility is a key part of what causes global warming.Currently, we are adding greenhouse gases to the atmosphere through the burning of fossil fuels.

Carbon dioxide's invisibility is a key part of what causes global warming.1. Forest Fires: is another leading cause of global warming. Natural forest fires are usually televised on the news, showing the devastation of mountain homes and communities. While this loss is tragic, the effects of these natural occurring forest fires pose a problem for the earth’s air. Forest fires emit carbon-filled smoke into the atmosphere, and new forests’ growth is slow and not stable enough to produce the much needed oxygen into the newly, suffocating carbon air. Natural forest fires will eventually run their course, but left in the ashes are polluting gases that get trapped in the atmosphere.According to the National Climate Assessment, human influences are the number one cause of global warming, especially the carbon pollution we cause by burning fossil fuels and the pollution-capturing we prevent by destroying forests. The carbon dioxide, methane, soot, and other pollutants we release into the atmosphere act like a blanket, trapping the sun's heat and causing the planet to warm. Evidence shows that 2000 to 2009 was hotter than any other decade in at least the past . This warming is altering the earth's climate system, including its land, atmosphere, oceans, and ice, in far-reaching ways.The increase of greenhouse gas concentration (mainly carbon dioxide) led to a substantial warming of the earth and the sea, called . In other words: The increase in the man-made emission of greenhouse gases is the cause for global warming. For the effects of global warming see below. Our personal vehicles are a major cause of global warming. Collectively, cars and trucks account for nearly one-fifth of all US emissions, emitting around 24 pounds of carbon dioxide and other global-warming gases for every gallon of gas. About five pounds comes from the extraction, production, and delivery of the fuel, while the great bulk of heat-trapping emissions—more than 19 pounds per gallon—comes right out of a car’s tailpipe.6. Fertilizer Use: Think of the countless farmlands across the heartland of America. The unique thing about fertilizer is that it produces nitrous oxide once it absorbs the soil. Nitrous oxide is 300 times more dangerous than carbon dioxide. The EPA strongly warns that the farming industry’s use of fertilizer is one of the leading causes of global warming.4. Overpopulation: Another cause of global warming is . Since carbon dioxide contributes to global warming, the increase in population makes the problem worse because we breathe out more carbon dioxide in the atmosphere. More people means more demand for food, more carbon dioxide in the atmosphere, more demand for cars and more demand for homes. Some have confused global warming as persistent, increasing warmth. While the global temperature is increasing, it may not translate to a higher temperature in an individual location. "Global warming is important because it is so persistent and global in scale, and because it brings more extreme events such as heat waves - not because it makes every place warm all the time. It doesn't do that," said atmospheric scientist Adam Sobel, author of "" (HarperWave, 2014). In addition to heat waves, the increase in global temperature is having a massive effect on the environment, such as melting polar ice caps, raising the sea level and fueling dangerous and severe weather patterns. Understanding the causes of global warming is the first step to curbing its effects.
