Consenso científico (90-100%): los humanos hemos causado el cambio climático

Global warming attribution studies consistently find humans are responsible for all global warming over the past six decades.

A new study published in Climate Dynamics has found that humans are responsible for virtually all of the observed global warming since the mid-20th century. It’s not a novel result – in fact, most global warming attribution studies have arrived at the same general result – but this study uses a new approach.(…)

In other words, this new paper adds to the mountain of evidence pointing to humans as the dominant cause of global warming since 1950, using a new statistical approach to answer the question. Disentangling how much warming human carbon pollution has caused from the amount of cooling caused by human aerosol pollution remains a challenging task, but rapid global warming is the net result of human activities.

This mountain of scientific and statistical evidence is the reason why there is a 90–100% consensus among climate science experts that humans are responsible for global warming. It’s what scientists call a “knowledge-based consensus”, as described in the video below.
