    Continueing the trend of stronger statements on the dangers of the warming that we are seeing from scientific societies.

    http://www.geolsoc.org.uk/webdav/si...nge - evidence from the geological record.pdf

    What are the grounds for concern?
    The last century has seen a rapidly growing global population and much more intensive use of resources, leading to greatly increased emissions of gases, such as carbon dioxide and methane, from the burning of fossil fuels (oil, gas and coal), and from agriculture, cement production and deforestation. Evidence from the geological record is consistent with the physics that shows that adding large amounts of carbon dioxide to the atmosphere warms the world and may lead to: higher sea levels and flooding of low-lying coasts; greatly changed patterns of rainfall2; increased acidity of the oceans 3,4,5,6; and decreased oxygen levels in seawater7,8,9.
    There is now widespread concern that the Earth’s climate will warm further, not only because of the lingering effects of the added carbon already in the system, but also because of further additions as human population continues to grow. Life on Earth has survived large climate changes in the past, but extinctions and major redistribution of species have been associated with many of them. When the human population was small and nomadic, a rise in sea level of a few metres would have had very little effect on Homo sapiens. With the current and growing global population, much of which is concentrated in coastal cities, such a rise in sea level would have a drastic effect on our complex society, especially if the climate were to change as suddenly as it has at times in the past. Equally, it seems likely that as warming continues some areas may experience less precipitation leading to drought. With both rising seas and increasing drought, pressure for human migration could result on a large scale.

    Cement production. There's talk of that in another thread as I recall.

    Can you say Anthropocene?...

    Study: Human Imprint Has Thrust Earth Into New Geological Epoch
    January 07, 2016 — The indelible imprint left by human beings on Earth has become so clear that it justifies naming a new geological epoch after mankind, experts said Thursday.

    Yeah...that whole atomic age thing probably should have it's own defining point. Of course the "would take years of research" part for the rest of it is a transparent "we need more funding" request.

    OK, time for an update;

    http://sciencepolicy.agu.org/files/2013/07/AGU-Climate-Change-Position-Statement_August-2013.pdf

    Human‐Induced Climate Change Requires Urgent Action Humanity is the major influence on the global climate change observed over the past 50 years. Rapid societal responses can significantly lessen negative outcomes. Human activities are changing Earth’s climate. At the global level, atmospheric concentrations of carbon dioxide and other heat‐trapping greenhouse gases have increased sharply since the Industrial Revolution. Fossil fuel burning dominates this increase. Human‐caused increases in greenhouse gases are responsible for most of the observed global average surface warming of roughly 0.8°C (1.5°F) over the past 140 years. Because natural processes cannot quickly remove some of these gases (notably carbon dioxide) from the atmosphere, our past, present, and future emissions will influence the climate system for millennia. Extensive, independent observations confirm the reality of global warming. These observations show large‐scale increases in air and sea temperatures, sea level, and atmospheric water vapor; they document decreases in the extent of mountain glaciers, snow cover, permafrost, and Arctic sea ice. These changes are broadly consistent with long‐ understood physics and predictions of how the climate system is expected to respond to human‐caused increases in greenhouse gases. The changes are inconsistent with explanations of climate change that rely on known natural influences.

    The Geological Society of America - Position Statement on Climate Change

    Climate Change

    Adopted in October 2006; revised April 2010; March 2013; April 2015

    Position Statement
    Decades of scientific research have shown that climate can change from both natural and anthropogenic causes. The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2011), the Intergovernmental Panel on Climate Change (IPCC, 2013) and the U.S. Global Change Research Program (Melillo et al., 2014) that global climate has warmed in response to increasing concentrations of carbon dioxide (CO2) and other greenhouse gases. The concentrations of greenhouse gases in the atmosphere are now higher than they have been for many thousands of years. Human activities (mainly greenhouse-gas emissions) are the dominant cause of the rapid warming since the middle 1900s (IPCC, 2013). If the upward trend in greenhouse-gas concentrations continues, the projected global climate change by the end of the twenty-first century will result in significant impacts on humans and other species. The tangible effects of climate change are already occurring. Addressing the challenges posed by climate change will require a combination of adaptation to the changes that are likely to occur and global reductions of CO2 emissions from anthropogenic sources.

    Purpose
    This position statement (1) summarizes the scientific basis for the conclusion that human activities are the primary cause of recent global warming; (2) describes the significant effects on humans and ecosystems as greenhouse-gas concentrations and global climate reach projected levels; and (3) provides information for policy decisions guiding mitigation and adaptation strategies designed to address the current and future impacts of anthropogenic warming.

    Pretty unequivocal statements from the largest scientific societies in the US dealing with Geology.

    LOL,,,,,

    MORE POLITICAL BULL SHIT FROM OLD FRAUD!

    And they have zero scientific evidence to back up their assertions..

    Poor little retarded Silly Billy. The AGU has videos of their fall meeting every year, in which they have presentations from the actual scientists doing the work.



    All we have from you is the flap yap and lies from someone that has yet to present anything that indicates he even finished middle school.

    Someone inform the Leftard OP that geology has nothing to do with meteorology.
