Evidence For Human Caused Climate Change

Climate Change 101:

“There is virtually unanimous scientific agreement about climate change. Yet due to both the inherent complexity of the topic and the social controversies surrounding it, confusion and doubt often persist. Here are four central questions about climate change, together with brief answers based on the current best scientific understanding of climate change and links to more detailed information.”   Read: http://ncse.com/climate/climate-change-101

Every Major Scientific Organization In The World In Consensus That Humans Are Causing Climate Change:

List of Worldwide Scientific Organizations (Scientific Organizations That Hold the Position That Climate Change Has Been Caused by Human Action) http://opr.ca.gov/s_listoforganizations.php

The consensus among climate scientists on anthropogenic global warming is not “97%,” as has become widely believed. Instead, over 99.9% of publishing scientists accept that humans are causing global warming.


Climate Change Consensus

US Military On Climate Change:

“In fact, military leaders have been warning of climate change threats to national security since at least 2003. The authors of a report in 2007 told the Times the biggest change from 2007 to present was the increase in scientific certainty. (97% of climate scientists now agree climate-warming trends are very likely due to human activity).

“We have to be concerned about all of the global impacts [of climate change], including here at home, where the Defense Department does have a mission in supporting civil authorities in the event of natural disasters,” Sharon Burke, Assistant Secretary of Defense for Operational Energy Plans and Programs told Defense One in May. “We have to be concerned about all of it. We have to be pragmatic about it.” Read more: http://www.businessinsider.com/climate-change-military-2014-7#ixzz3gS3mCgL1

NASA on Climate Change:

“The current warming trend is of particular significance because most of it is very likely human-induced and proceeding at a rate that is unprecedented in the past 1,300 years.1

Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate.

The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response.” Read More: http://climate.nasa.gov/evidence/

How will climate change affect the world and our society?

Climate change will have many different effects on society and on the natural world. Plant and animal species are adapting to changing environments by migrating to new areas. As species move, they bring diseases with them to farms and human populations. Biodiversity diminishes as some species become extinct due either to human-caused climate change or to related human activities such as habitat destruction or toxic pollution. Higher temperatures create new risks for wildfires and place new pressures on farmers. Melting polar ice raises sea levels, putting coastal cities at greater risk of floods… Read: http://ncse.com/climate/climate-change-101/how-climate-change-affects-world-society
