The Consensus on Climate Change

Scientists are rigorous, they relish challenges and they are always looking to disprove or prove a hypothesis. This is why it's very important that Climate Change and the fact that we are causing it, are agreed upon by the overwhelming majority of scientists.

In fact the 3% of studies that supposedly fell outside of that consensus were proved to be flawed in recent studies. 

Here is some reading to back that up:

Consensus on consensus: a synthesis of consensus estimates on human-caused global warming

"We examine the available studies and conclude that the finding of 97% consensus in published climate research is robust and consistent with other surveys of climate scientists and peer-reviewed studies."

Learning from mistakes in climate research

This is the study that found the 3% of climate change denier studies were flawed or biased. Well worth a read. 

"A common denominator seems to be missing contextual information or ignoring information that does not fit the conclusions, be it other relevant work or related geophysical data. In many cases, shortcomings are due to insufficient model evaluation, leading to results that are not universally valid but rather are an artifact of a particular experimental setup. Other typical weaknesses include false dichotomies, inappropriate statistical methods, or basing conclusions on misconceived or incomplete physics. We also argue that science is never settled and that both mainstream and contrarian papers must be subject to sustained scrutiny"

Those 3% of scientific papers that deny climate change? A review found them all flawed

"researchers tried to replicate the results of those 3% of papers—a common way to test scientific studies—and found biased, faulty results"

Scientific Consensus: Why Should We Accept It?

"As opposed to politics, where vested interests contend for supremacy, science is a field where the single goal is to discover the truth. The spirit of science propels those who work in their various fields to make sure current popular beliefs are tested for veracity"

A little video to help introduce you to the topic:

How Do We Know That Global Warming Today is Man Made?

Like any detective story, the search for the culprit in the climate change saga takes diligence and the hard and fast rules of scientific investigation. After long and painstaking studies, research has repeatedly found the fingerprints of human activity on current global warming.

How is that possible?

Multiple models and studies have shown that there is a causal correlation between an increase in greenhouse gases and an increase in global temperatures, both of which have been on the rise since the industrial revolution. That is indisputable at this point. Now the reason we can tell that the increases are our fault (rather than due to natural cycles etc..) is because we can actually trace the origins of the greenhouse gases to particular sources, exactly like a fingerprint


Greenhouse gases from industry have a lighter weight, their 'combined signal' is different than a carbon molecule from natural sources. That is one way we know that human industry and activity is a cause of global warming.

It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases
— American Meteorological Society- 2012

All the models used to predict climate change that include human influence come up correct while natural influences either do not correlate or would predict a much different current and future climate than the one we are experiencing. 

In one study researchers managed to "apply diverse analyses to more than 1,700 species, and show that recent biological trends match climate change predictions" Read Article 

As for the notorious 3% of studies that supposedly contradict the scientific consensus on climate? Well a new review of those reports shows that they are all flawed.

We cannot continue to ignore or deny our part in climate change nor can we shirk our duty to act to mitigate and reverse global warming. 

The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.
— American Association for the Advancement of Science (2006)
Human influence on the climate system is clear, and recent anthropogenic emissions of greenhouse gases are the highest in history. Recent climate changes have had widespread impacts on human and natural systems

Volunteer to Help Climate Science

No matter what your job or background if you are interested in helping climate scientists do their work there are ways you can volunteer or contribute and we have some suggestions for you:

Earthwatch Institute

Earthwatch Institute has been pairing volunteers with researchers that need help collecting data and it is all exciting and hands on work in the field and in the lab. Here are some of their Climate expeditions you can join:




Discover more expeditions on Climate Change

Prefer to work online from the comforts of your own home or town? Well you can help with these apps and online citizen science options:



Brought to you by NOAA's National Severe Storms Laboratory and the University of Oklahoma and Cooperative Institute for Mesoscale Meteorological Studies this app lets you submit your weather observations from where you are.

Climate CoLab
From the MIT Center for Collective Intelligence

"The goal of Climate CoLab is to harness the collective intelligence of thousands of people from all around the world to address complex societal problems, starting with global climate change" Get working!


"The phytoplankton in the sea account for over 50% of all photosynthesis on Earth and, through the food web they support, theyunderpin the marine food chain. Living at the surface of the sea the phytoplankton are particularly sensitive to" Climate Change. You can help by downloading the app.

Organisations Fighting Climate Change

Congratulations! You are making a difference by deciding to join forces with others to fight climate change caused by global warming...

We have some recommendations for you:


This is the place to go to support major climate battles and get a wealth of resources on actions, activities and organising. You can donate to them or get active with help from their multitude of resources. 


If you haven't joined Greenpeace you can start by doing that, and you can also choose to donate to them to support their work globally. 

Union of Concerned Scientists

Support UCS if you want your efforts to back "rigorous science to work to build a healthier planet and a safer world". You can donate to them too.

Conservation International

Help Conservation International "empower people to protect the nature that we rely on for food, fresh water and livelihoods". You can donate to help. 

Don't Forget

Check with your school, place of work or town to see what climate initiatives they have in place and join them. If they are doing nothing yet, then it's your chance to be a trailblazer and get them started!
