Overall, the panel's reports have never focused much on research examining how humans respond (or fail to respond) to certain kinds of risk, particularly «super wicked» problems such global warming, which is imbued with persistent uncertainty on key points (the pace of sea - level rise, the extent of warming from a certain buildup of greenhouse gases), dispersed and delayed risks, and a variegated menu of possible responses.

By that I mean an unvarnished depiction of what science has, and has not, revealed about the potential for dangerous outcomes from the building blanket of human - generated greenhouse gases in the atmosphere, and about the strengths and limits of possible responses.

Including the idea of carbon removal enables us to explain climate change in as simple a way as possible: climate change is caused by the giant (albeit invisible) mess humans are making in the sky by emitting carbon dioxide and other greenhouse gasses.

In the 1980's, greenhouse gas (GHG) emissions from human activity became a worldwide concern and are a possible cause of climatic changes.

It is not the first such optimistic study: researchers have lately argued that the 2 °C target set in Paris is possible, if humans start reducing greenhouse gas emissions towards zero, and do so within 40 years.

Beginning in the late 1960s, computer simulations indicated possible changes in temperature and precipitation that could occur due to human - induced emission of greenhouse gasses into the atmosphere.

«[Senator Cruz argues that the] mismatch between modeled and observed tropospheric warming in the early 21st century has only one possible explanation — computer models are a factor of three too sensitive to human - caused changes in greenhouse gases (GHGs)[13, pages 1 and 2].

This will help scientists explore, more accurately than is possible today, how rising temperatures, shifting precipitation patterns, increasing greenhouse gas levels, and other natural and human - induced changes affect tropical forests» influence on Earth's climate.

They also discovered that such a huge shift in the jet stream would not have been possible without anthropogenic, or human - caused, greenhouse gas emissions.

On the basis of well - established evidence from the past 20 years, there is now wide consensus among scientific organizations and approximately 97 % of climatologists that human - generated greenhouse gas emissions are the cause of climate change.1 — 4 Although the effects of climate change are already being felt across the world, the magnitude of the effects of future changes depends on our ability to substantially reduce greenhouse gas emissions and implement adaptation strategies within the ensuing decades.5 Thus, it remains possible to protect children, families, and communities from the worst potential effects of climate change.

32 Human Impact on Climate Change The Greenhouse Effect Is a natural warming of both Earth's lower atmosphere and surface Makes life as we know it possible Major Gases: Water Vapor and Carbon Dioxide Humans have added more greenhouse gases to the atmosphere in the past 200 years by burning foGreenhouse Effect Is a natural warming of both Earth's lower atmosphere and surface Makes life as we know it possible Major Gases: Water Vapor and Carbon Dioxide Humans have added more greenhouse gases to the atmosphere in the past 200 years by burning fossil Gases: Water Vapor and Carbon Dioxide Humans have added more greenhouse gases to the atmosphere in the past 200 years by burning fogreenhouse gases to the atmosphere in the past 200 years by burning fossil gases to the atmosphere in the past 200 years by burning fossil fuels

And if the climate is currently warming, and we can (and have) eliminated other possible causes for that change, then human produced greenhouse gasses are the most likely cause of our current warming.

We further recognize the need to reduce the global emission of greenhouse gases by 80 % by mid-century at the latest, in order to avert the worst impacts of global warming and to reestablish the more stable climatic conditions that have made human progress over the last 10,000 years possible.

They also now realize that other greenhouse gases are being released into the atmosphere as the result of human activity, and that they additionally contribute to global warming and possible climate change.
