"Consensus on climate change?
They smoke you out!
There has never been a poll of all scientists, not even scientists who study climate. The “anthropogenic causes of man-made global climate change hypothesis,” also known by the acronym CAGW, is a theoretical threat, more often than not used by for-profit environmental fundraising groups.
Evidence is what matters in science - Science is not a democracy
Ask an astrophysicist
Why do you need an astrophysicist to talk about climate? Because the earth's climate is affected by factors outside of our atmosphere. Dr. Nir Shaviv explains it in simplified terms in this video:
Dr. Nir Shaviv discusses the 97% consensus and shows some evidence that climate change is influenced by the sun and not carbon dioxide.
Who are the climate experts? - The IPCC or the solar physicists?
The Intergovernmental Panel on Climate Change (IPCC) is a political organization with a mandate to study climate change caused only by humans - not ALL causes. Dr. Shaviv explains that they only include a nominal aspect of the solar effect in the IPCC studies.
How does the sun influence climate change?
This is a HUGE subject that we cover on this site. Dr. Shaviv gives us a little idea of how the sun influences the climate in the following excerpt.
There are several human-caused impacts on the earth - it's not just about carbon dioxide (CO₂) - But natural factors are more important.
Most scientists agree that humans have an impact on the climate - however, very few agree with the “climate catastrophe” version. Also, scientists disagree what has more impact on climate:
Most scientists agree that humans have an impact on the climate - however, very few agree with the “climate catastrophe” version. Also, scientists disagree what has more impact on climate:
⦁ Deforestation (humans cutting down or burning forests - large fires create tons of toxic gases, soot and explosive energy exhausts, which can generate pyrocumulonimbus clouds that rise higher than the tropopause, even higher than Mount Everest);
⦁ Soil disturbance (agriculture, construction of roads and paving, construction of towns);
⦁ The urban heat island (The heat generated by cities creates a heat bubble);
⦁ Black carbon, or soot, generated by the combustion of fossil gases, falling back into arctic snow and being able to cause warming (black absorbs light, white snow reflects it);
⦁ Aerosols - other types of gases and vapors come from human industrial activities - some of these cause cloud formation or affect precipitation;
⦁ Water disturbance - drainage of wetlands or construction of dams and reservoirs can affect local precipitation trends. ;
Is there a consensus of some sort?
Yes. Some scientists and individuals agree that humans influence climate and temperature in one way or another. That's all.
Where does this 97% consensus come from?
Four different polls, like that of Oreskes (2004) which Al Gore refers to in his film, claim to find an “overwhelming consensus” on climate change. The four polls are biased and infested with statistical manipulation. Three of them focused on summaries (an introductory summary of about 150 words) of scientific studies made by different groups of scientists; one of these studies being just a "poll of opinions"! (Science is based on evidence, not opinions!) What the consensus “claims” is that supposedly scientists “all agree” that climate disasters are imminent and largely due to human activities, especially climate change. carbon dioxide, due to our use of fossil fuels like oil, gas and coal. Only 1 to 3% of the scientists surveyed have academic publications that agree with the visions of disaster. Most have ABSOLUTELY NO OPINION.
