annestacey-if that the case way is the temperature rising in the surrounding planets at/near the same rate as earth?

The greenhouse gas carbon dioxide (CO2) is the most abundant gas (after water) emitted by volcanoes. Volcanologists estimate an annual global output of 200 million tons of volcanic CO2 per year. This natural source is balanced by natural processes that remove CO2 from the atmosphere-specifically by the weathering of rock into soil by atmospheric CO2 dissolved in rain and surface waters.
By comparison, human activities such as the burning of fossil fuels and deforestation produce 130 times more CO2 than all the world's volcanoes put together (adding 26,000 million tons of CO2 to the atmosphere each year, the equivalent of 8,000 Kilaueas (Hawaii's most active volcano). This comparison suggests humans are producing CO2 at a rate unprecedented in a geological history stretching back many millions of years. Clearly, there is need to think seriously about the implications of human CO2 emissions and to consider how current energy policy and land use practices may impact our collective future.

our fossil fuel burning is no where near as being as effective as a single volcano, let alone many volcanos.
what my point is- this entire campaign of global warming is a fraud(as its presented). in the past people didnt want to talk about it becuase they would lose money. now they want to talk about it becuase they can make money.
its true the planet is getting warmer, but we need to assess all the information before we start pointing fingers.
i stated befor the temp rise is across the entire solar system. that alone suggests its not a human aspect.
the HORIZON PROJECT is a good place to look in to, there are are a few threads on ATS that go into it.
Comparison of CO2 emissions from volcanoes vs. human activities.
Scientists have calculated that volcanoes emit between about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere every year (Gerlach, 1999, 1992). This estimate includes both subaerial and submarine volcanoes, about in equal amounts. Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 22 billion tonnes per year (24 billion tons) [ ( Marland, et al., 1998) - The reference gives the amount of released carbon (C), rather than CO2.]. Human activities release more than 150 times the amount of CO2 emitted by volcanoes--the equivalent of nearly 17,000 additional volcanoes like Kilauea (Kilauea emits about 13.2 million tonnes/year)!
Present-day carbon dioxide (CO2) emissions from subaerial and submarine volcanoes are uncertain at the present time. Gerlach (1991) estimated a total global release of 3-4 x 10E12 mol/yr from volcanoes. This is a conservative estimate. Man-made (anthropogenic) CO2 emissions overwhelm this estimate by at least 150 times.
Since 1751 roughly 305 billion tons of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. Half of these emissions have occurred since the mid 1970s. The 2003 global fossil-fuel CO2 emission estimate, 7303 million metric tons of carbon, represents an all-time high and a 4.5% increase from 2002.
Globally, liquid and solid fuels accounted for 76.7% of the emissions from fossil-fuel burning in 2003. Combustion of gas fuels (e.g., natural gas) accounted for 19.2% (1402 million metric tons of carbon) of the total emissions from fossil fuels in 2003 and reflects a gradually increasing global utilization of natural gas. Emissions from cement production (275 million metric tons of carbon in 2003) have more than doubled since the mid 1970s and now represent 3.8% of global CO2 releases from fossil-fuel burning and cement production. Gas flaring, which accounted for roughly 2% of global emissions during the 1970s, now accounts for less than 1% of global fossil-fuel releases.
Emissions of CO2 by human activities, including fossil fuel burning, cement production, and gas flaring, amount to about 22 billion tonnes per year (24 billion tons)
