I Am Concerned About Climate Change

[b]Scientific evidence for warming of the climate system is unequivocal.
- Intergovernmental Panel on Climate Change[/b]

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.

In the 1860s, physicist John Tyndall recognized the Earth's natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations. In 1896, a seminal paper by Swedish scientist Svante Arrhenius first predicted that changes in the levels of carbon dioxide in the atmosphere could substantially alter the surface temperature through the greenhouse effect.

[@6578,HoraceGreenley] "The overwhelming evidence of human-caused climate change documents both current impacts with significant costs and extraordinary future risks to society and natural systems. The scientific community has convened conferences, published reports, spoken out at forums and proclaimed, through statements by virtually every national scientific academy and relevant major scientific organization — including the American Association for the Advancement of Science (AAAS) — that climate change puts the well-being of people of all nations at risk."

[@6578,HoraceGreenley] indeed. Unicorns cause global warming. Good riddance.

Quotation from page 6: "The number of papers rejecting AGW [Anthropogenic, or human-caused, Global Warming] is a miniscule proportion of the published research, with the percentage slightly decreasing over time. Among papers expressing a position on AGW, [b]an overwhelming percentage (97.2% based on self-ratings, 97.1% based on abstract ratings) endorses the scientific consensus on AGW.”[/b]

I'm not getting any joy from the facts of global warming. I'm in the same boat as everyone else. A mature adult, when confronted with overwhelming evidence and facts, faces the problem squarely and decides the best course of action.

[@1149,MrBrownstone] Either term will do.
MrBrownstone · 41-45, M
[@601940,badminton] Wrong. 2 different ideas.
windinhishair · 61-69, M
[@1149,MrBrownstone] Two different ideas only to people who don't understand the science. Scientists changed the terminology to global climate change from global warming because people like you couldn't understand that while the planet was warming, some areas may actually get colder due to changes in wind and sea currents and other factors. So it is the same phenomenon no matter what you call it.

These guys are a joke. Wha happened to global warming? Get your lies straight.

[@1149,MrBrownstone] The following page from the Gov't Office of Planning and Research, lists the nearly 200 worldwide scientific organizations that hold the position that climate change has been caused by human action.

And at one time scientists said the sun revolves around the earth.

[@1149,MrBrownstone] They really said that?
badminton · 61-69, MVIP
[@1149,MrBrownstone] No they didn't. The Catholic church of the middle ages said that.
