This is the question of global warming.
After researching many sites, such as National Aeronautics and Space Administration (NASA), University studies, Intergovernmental Panel on Climate Change (IPCC) studies, Nongovernmental International Panel on Climate Change (NIPCC), and more, global warming is very complicated.

However, regardless of the current increase in the level of carbon dioxide, previous studies indicate that the current rate of global warming is lower in comparison to the historical data recorded for 450,000 years....
This essay has presented Earth’s many changing faces during its journey. Earth had molten beginnings, was , and may have . Later, and and . Earth experienced swings from to conditions as atmospheric gases dramatically changed, continents moved, and vast and of complex life played out on land and sea. But the changes happened over timescales of millions and billions of years, not hundreds. No climate scientist will deny that carbon dioxide traps infrared radiation and warms Earth’s atmosphere. The vented enough carbon dioxide into the atmosphere to create 200 million years of Greenhouse Earth conditions, when reptiles ruled Earth. Volcanism waned and around 150-to-100 mya. By 35 mya, and the Antarctic ice sheet began forming. Every paleoclimate study I have seen places greenhouse gas (and primarily carbon dioxide) concentrations as the primary determinant of global surface temperatures, after the Sun's radiation, but the Sun's output is considered to have been exceptionally stable and has risen slowly over the eons. , usually by accentuating the carbon dioxide with a positive feedback effect that may have reached runaway conditions at times.
We, as humans, are responsible for global warming.
Because the Western Hemisphere’s inhabitants were virtually all in their Stone Age, they as greatly as Old World civilizations did, and many societies were environmentally sustainable and provided seeming answers to questions that scientists have asked about Old World civilizations’ development. The natives of coastal California were familiar with agriculture, as it was practiced by nearby inland tribes, but they never adopted it. California was so bountiful, and its climate was so human-friendly, that its natives retained their hunter-gatherer lifestyle. Similarly, northward on the Pacific Northwest's coast, natives created an economy in which half of its calories derived from salmon runs, and those peoples were relatively sedentary without agriculture. Natives turned the Great Plains into a big pasture for bison, and the biome was partly maintained by annual burning of the grasslands. In Mesoamerica, farming has been sustainable for thousands of years. In the Amazon, the natives transformed the rainforest, and a higher proportion of plants and trees provided human-digestible foods than in any other “wild” place on Earth, those natives also terraformed thin tropical soils with ceramics (maybe unintentional) and charcoals (intentional) and made super-soils called and . In summary, native practices in the Western Hemisphere were often sustainable if not quite abundant. But when civilizations arose, they had problems that were like their Old World counterparts'. Their problems were also environmental and not just the injustices of hierarchal societies, often steeply hierarchical.
These are just a few contributing factors of global warming.
With industrialization, peoples could export their environmental devastation onto other unfortunates. An early trick of industries was making the smokestacks taller so that the pollution was “airmailed” to their neighbors. Japan regenerated its forests by importing timber from raped forests abroad, mostly from the Asian mainland and North America. Burning fossil fuels has also raised the atmosphere’s carbon dioxide content, which has warmed Earth. It that the radiation-absorbing properties of greenhouse gases were measured, and it before scientists began to suspect that the fossil fuel era might be warming Earth’s atmosphere. A century later, there is still a faux debate regarding the atmospheric-warming effects of burning fossil fuels, and I will briefly address the issue.
The world is changing because of Global warming.
Economics is the study of humanity’s material well-being, but humans have rarely thought past their immediate economic self-interest, even when the long-term prospects were obviously suicidal, such as today’s global energy paradigm. Because environmental issues affect humanity’s material well-being, they are economic in nature. As can be seen so far in this essay, there was little awareness or seeming caring in early civilizations whether they were destroying the very foundations of their civilizations. Even if they did not care how much other life forms suffered, they did not seem to realize that it also meant that those oppressed and exterminated organisms and wrecked environments would not provide much benefit to humanity in the future, especially energy, whether it was food or wood.
