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"
