A new analysis of 40 years of satellite data shows that it is almost certain that humanity is actively causing global climate change.
Climate deniers often claim, given overwhelming evidence, that the planet is heating up, and natural disasters are becoming more intense and frequent just because they are – falsely claiming that humanity's love affair with fossil fuels has nothing to do with it.
Now scientists say the probability of that being true is only one in a million.
According to research by the Californian Lawrence Livermore National Laboratory, this is because climate data has now reached a so-called "gold standard". From scientific evidence ̵
"The narrative that scientists do not know the cause of climate change is wrong," said Benjamin Santer, the researcher who led the research, to Reuters. "We do."
The scientific research process almost never eliminates uncertainty: researchers are exploring their hypotheses to better understand the world, but there is almost always another factor that could have influenced their outcomes.
In other words, a gold standard is not something that is reckless.
The new analysis examined the three largest satellite datasets used by climate scientists. It shows that two of these datasets reached the gold standard of certitude that humanity caused climate change in 2005 and the third in 2016.
This level of certainty, which is very unusual in scientific research, affects the Earth very clearly. And now we have to figure out what to do about it.
"Humanity can not afford to ignore such clear signals," says the analysis.
