The lines
of evidence and analysis supporting the mainstream position on
climate change are diverse and robust — embracing a huge body
of direct measurements by a variety
of methods in a wealth
of locations on the Earth's surface and from space, solid
understanding of the basic physics governing how energy flow in the atmosphere interacts with greenhouse gases, insights derived from the reconstruction
of causes and consequences
of millions
of years
of natural climatic variations, and the results
of computer models that are increasingly capable
of reproducing the main features
of Earth's
climate with and without
human influences.

The statement continues: «While the
understanding of the drivers and consequences
of climate change will continue to advance with additional research, the fundamental premise remains sound that
human life has altered the atmosphere and is one
of the
causes of climate change.»
Most don't
understand models or the mathematics on which they are built, a fact exploited by promoters
of human caused climate change.
Their work encompasses a range
of problems and time scales: from five - day model predictions
of hurricane track and intensity, to
understanding the
causes of changes in extremes over the past century, to building new
climate prediction models for seamless predictions out to the next several years, to earth system model projections
of human -
caused changes in various extremes (heat waves, hurricanes, droughts, etc.) over the coming century.
But neglecting causation in the opposite direction (clouds
cause temperature) can lead to large errors in our
understanding of how and why the
climate system
changes, as well as in our diagnosis
of how sensitive the
climate system is to
human influences.»
So people not admitting that «
climate change» is
human cause... don't
understand any
of the points above.
As Edward Maibach, director
of the Center for
Climate Change Communication at George Mason University, says, people are influenced largely «by what their friends and family members think about climate change, by news media coverage of climate science, (for example, the recent release of the third National Climate Assessment), by their understanding of the scientific consensus about human - caused climate change, by statements made by the political leaders they trust, and by their own «personal experiences» with climate change.

The study cites Spencer and Bast along with other «manufacturers
of doubt,» whose work to undermine the public
understanding of this consensus has been stunningly successful — only 12 percent
of Americans, their previous work found, know that more than 90 percent
of scientists agree on this — and has resulted in «cascading effects on public
understanding that
climate change is happening,
human caused, a serious threat, and in turn, support for
climate change mitigation and adaptation policies.»
While you acknowledged that the
climate is
changing and that
humans are having an impact on it, it is critically important that you
understand that emissions
of carbon dioxide and other greenhouse gases are the primary
cause.
To
understand why «this current» global warming is
human caused and not natural cycle, one needs to get an idea
of what the natural cycle is and what are the basic mechanisms that
cause climate change in the natural cycle.
Scientists know that recent
climate change is largely
caused by
human activities from an
understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns
of climate change caused by different
human and natural influences.

of taking action.
It is the
understanding of the power
