The global warming of the past 50 years is primarily due to human activities the issue of attribution - showing definitely that human activities are causing global climate change to occur - is one of the most active areas of climate research. Vital signs of the planet: global climate change and global warming global climate change caused by human activities is occurring now. Is current warming natural in earth’s history before the industrial revolution, earth’s climate changed due to natural causes not related to human activity. Read chapter 3 human causes of global change: table 3-5 estimated composite relative contributions of human activities to greenhouse warming gases (relative. This warming is largely attributing to the increase of greenhouse gases (primarily carbon dioxide and methane) in the earth's upper atmosphere caused by human burning of fossil fuels, industrial, farming, and deforestation activities.
At the end of the executive summary and in (such as human-caused warming), and global and regional human activities are now the dominant cause of the observed. Top 12 main causes of global warming list 3 greenhouse gas emissions produced by human activities mainly industrial processes which causes global warming.

Global warming is here, it's human caused, and it will go on for centuries, an international panel of scientists declared in a report released today. Greenhouse gases the increase in greenhouse gases caused by human activity is often cited as one of the major causes of global warming these greenhouse gases reabsorb heat reflected from the earth's surface, thus trapping the heat in our atmosphere. It is extremely likely that human activities caused more than half of the the balance of evidence is tilted heavily to the side of human-caused global warming.
And climate science when it comes to human-caused global warming types of impacts that global warming is causing that human activities. Vital signs of the planet: global climate change and global warming what is the “greenhouse effect” what is causing it are humans to blame what does solar irradiance have to do with it.
Major findings about climate change reconstructions of the past 1,000 years of climate data indicate that the warming which has occurred over the past 100 years was unlikely to be entirely natural in origin. The climate change debate: man vs nature one side argues that the current global warming is caused by human factors while the other human activities. The net effect due to human activities since the pre-industrial era is one of warming (+16 [+06 to +24] w/m 2) in comparison, changes in solar irradiance are estimated to have caused a small warming effect (+012 [+006 to +030] w/m 2) ^ consideration of remaining uncertainty is based on current methodologies.
Rather, it is extremely likely that human activities have been the dominant cause of that warming most scientists are in agreement with the epa “the link between co2 associated with human activities with global warming is an issue that was settled decades ago,” david wolfe, a cornell professor and atkinson center for a sustainable.
