The Geological Society of America - Position Statement on Climate Change
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), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse-gas emissions) account for most of the warming since the middle 1900s. If current trends continue, the projected increase in global temperature by the end of the twenty-first century will result in significant impacts on humans and other species. 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 strengthened basis for the conclusion that humans are a major factor responsible for 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 future impacts of anthropogenic warming.
One of the larger Scientific Societies concerned with earth sciences.
You sure do love promoting the lies, don't you?
And you love to flap a lying yap, with zero support for your arguements. By the way, I thought that this was a Zone 2 now, or do those rules only apply to those that recognize science?

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.
