As described below, when climate scientists removed the warming factors they chose to create in their models, the results showed lower temperatures. They seem unaware or uninterested that this proves little or nothing, but label it science anyway and say their studies attribute most of the blame for any observed warming to human factors.

Since 1880, the average global temperature on Earth has increased by at least 1.1 °C. The culprit? Climate change, of course, asserts Phys.org.
Getting hotter, faster
According to findings released by the World Weather Attribution (WWA) initiative, a global collaboration between climate scientists and specialists, the record temperatures would have been up to 4 °C cooler without human-caused climate change.
The hottest day ever (40.3 °C) in the UK was registered on 19 July. The WWA analysis also claims [sic] that climate change made this heatwave 10 times more likely.

Dr. Radhika Khosla from the Oxford Smith School of Enterprise and the Environment applauded the WWA’s efforts:
“By carrying out rapid analysis based on established, peer-reviewed methods the WWA team are able to get evidence-based results into the public domain while we can all still remember the major disruptions from last week’s extreme heat. This is the latest in a series of studies that all show the same result: climate change makes heatwaves more likely and more intense.”
The heat is on
The scientists combined observations of temperature records over the years and climate models, or simulations, to determine human impact on extreme heat. “Because we know very well how many greenhouse gases have been put into the atmosphere since the beginning of the industrial revolution, we can take these things out of the model and simulate a world that might have been without climate change,” Dr. Otto explained to ‘BBC’.
“Every little bit of warming really makes these types of events more likely and even hotter. Heatwaves are much more deadly than other extreme weather like floods and climate change is a game-changer for heatwaves.”
We don’t need science to tell us that extreme heat events are becoming more frequent and last longer around the world. Nor do we need science to tell us who can reverse this dangerous trend.
