In 1996, when climate research was more certain about the link between fossil fuel combustion and climate change than during the time of Shaw's memo, Exxon's new chairman and chief executive Lee Raymond said in a speech in Detroit: «Currently, the scientific evidence is inconclusive as to whether human activities are having a significant effect on the global climate.»

Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 27 billion tonnes per year (30 billion tons)-LSB-(Marland, et al., 2006)-- The reference gives the amount of released carbon (C), rather than CO2, through 2003.].

About 40 percent of methane is emitted into the atmosphere by natural sources like wetlands and termites, with the rest coming from human activities like cattle breeding, rice growing, fossil fuel exploitation, landfills and biomass burning.

What's lost in a lot of the discussion about human - caused climate change is not that the sum of human activities is leading to some warming of the earth's temperature, but that the observed rate of warming (both at the earth's surface and throughout the lower atmosphere) is considerably less than has been anticipated by the collection of climate models upon whose projections climate alarm (i.e., justification for strict restrictions on the use of fossil fuels) is built.

Without releases from fossil fuels and other human activities the concentration would be about 125 ppm less.

When we talk about climate change, we're talking about the scientifically observable — and increasingly severe — changes in global climate patterns that became apparent in the mid-to-late twentieth century and can be attributed to the rising levels of atmospheric greenhouse gases (carbon dioxide, in particular) produced by human activities like burning fossil fuels.

«Climate Change» is a general term used when referring to a wide range of effects brought about by human activities such as burning fossil fuels, deforestation, and «heat island effects» resulting from buildings and pavement in the major human settlements.

Our movement is about both pulling hard on the brakes of the fossil fuel industry's activities, while pushing hard on the accelerator of the transition towards a fair and renewable future for all.

Among those who have taken some interest in addressing climate change, there have over the last decade or so been discussions about whether a focus on curtailing the activities of the fossil fuel industries or a focus on reducing demand for fossil fuels is the right single or leading method to move society into a transition away from fossil energy.

The red numbers and arrows show the additional fluxes caused by human activities averaged over 2000 - 2009, which include emissions due to the burning of fossil fuels, cement production and land use change (in total about 9 PgC / year).

In the context of fossil fuel production and transportation, underground is home to a number of activities about which the public has a dire need to be well informed.

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.»
