Greenhouse gases released by the burning of fossil fuels have steadily risen in the world's atmosphere since the industrial revolution, trapping heat and leading to a global increase in average temperatures.

Since the start of the industrial revolution, carbon dioxide levels are believed to have risen by about one - third, largely due to the burning of fossil fuels.

In the two centuries since the Industrial Revolution, we have wrapped the Earth in a layer of technology, powered by the burning of fossil fuels, whose exhaust products are pooling in the gas bubble that surrounds our blue marble.

Today, science tells us that we have increased the amount of carbon dioxide in our atmosphere by 40 % since 1880 by burning fossil fuels, such as coal, oil, and natural gas, for our energy needs.

1) If we accept that the radiative forcing equations are correct and that a doubling of CO2 will cause an increase of 3.7 W / m2 and that will cause an increase in 1C we have to figure out what is the equation for normalizing this doubling of CO2 so as to get rid of the reference point Ex: doubling of CO2 from 1ppm to 2 ppm will not increase the temperature by 1C 2) Since 1980 mankind has increased fossil fuel burning by 75 % but CO2 in atmosphere has only increased 21 %.

As long as humans continue to increase the greenhouse effect by burning massive quantities of fossil fuels, the planet will continue to warm, as is clear from the acceleration of global warming since 2000.

The CDIAC has told us how much CO2 we've added to the atmosphere since 1750 by burning fossil fuels, making cement, and changing land use (slash and burn etc.).

Since 1750, we have emitted about 580 billion tonnes of carbon into the atmosphere by burning fossil fuels, cutting down forests and making cement.

We are told that there is an overwhelming agreement, or consensus, among scientists that most weather and climate changes that have occurred since the mid-20th century have been caused by human activity — our fossil fuel burning and CO2 emissions in particular.

The carbon dioxide that is building in the atmosphere, at least in part, gets there through human emissions of carbon dioxide that are the by - product of burning fossil fuels (coal, oil, natural gas) to produce the vast majority the energy that has powered mankind's industrial and technical ascent since the Industrial Revolution.

Since the beginning of the Industrial Revolution, people have been releasing carbon dioxide into the atmosphere by burning fossil fuels and clearing forests.

Concerning the CO2 in the atmosphere I personally am 100 % (not 99.9999 % but 100 %) convinced by the arguments that — we know the emissions from burning fossil fuels, — we know the increase in CO2 concentration since Keeling started his measurements at Mauna Loa — we have a rough, certainly inaccurate, but still very significant understanding on the movements of carbon in atmosphere, biosphere, oceans and continents.

On the question of whether observed changes in climate can be attributed to human activities such as burning fossil fuels, Bolin noted that «The global mean temperature has increased by 0.3 - 0.6 degrees C since the late 19th century, and about 0.3 degrees over the last 40 years.»

Already, more than 10,000 people die each day from the small particles emitted from fossil - fuel burning; each year, 339,000 people die from wildfire smoke, in part because climate change has extended forest - fire season (in the U.S., it's increased by 78 days since 1970).

I've been following this topic since the mid-90's and from what I've read, I think they want to stop the burning of fossil fuels mainly in developed countries as well as put the clamps on democracy, and redistribute our wealth to developing countries for two reasons: 1) to bring down their fertility rates by development and 2) to provide reliable electric power to areas of the world without it so that the NSA can easily keep track of the rest of the world's population.

However, I read in Kate Ascher's book The Works that the MTA is by far the largest consumer of electricity in the city, and since power is generated by burning fossil fuels, I find myself wondering how much gasoline it saves to use the subway versus, say, driving a hybrid or taking the bus?

Published last week in the journal Science, researchers from New Zealand's National Institute of Water and Atmospheric Research (NIWA) found that the majority of methane released into the atmosphere since 2006 was produced by bacteria, pointing to sources like agriculture — rather than sources like fossil fuel production or the burning of organic material — as the culprit behind the increase in methane levels.

By contrast current climate change is caused by the thermal effects of CO2 emissions from burning of some 300 billion tons of fossil fuel since the dawn of the industrial age, with consequent increase of CO2 to 380 parts per million, 36 percent above maximum levels (about 280 parts per million) which pertained over the last one million years (The PleistoceneBy contrast current climate change is caused by the thermal effects of CO2 emissions from burning of some 300 billion tons of fossil fuel since the dawn of the industrial age, with consequent increase of CO2 to 380 parts per million, 36 percent above maximum levels (about 280 parts per million) which pertained over the last one million years (The Pleistoceneby the thermal effects of CO2 emissions from burning of some 300 billion tons of fossil fuel since the dawn of the industrial age, with consequent increase of CO2 to 380 parts per million, 36 percent above maximum levels (about 280 parts per million) which pertained over the last one million years (The Pleistocene).
