After a series of embarrassing predictions and wild factual errors damaged global-warming alarmists’ credibility — possibly beyond repair — the United Nations is again warning of impending doom: localized floods and droughts caused by climate change theoretically linked to human activity. But skeptics are still not buying.
The new report unveiled over the weekend by the UN Inter-governmental Panel on Climate Change (IPCC) claims extreme weather is set to increase dramatically in the decades ahead. But following spectacular failures in its last major report that turned the climate body into a global laughingstock, the UN used far more caution in attributing its predictions to anthropogenic (human-caused) factors.
According to a draft of the report cited by the BBC, it was only considered “likely” that human activities could be linked to changes in cold and warm days. Meanwhile, there was just “medium confidence” that man is responsible for extreme rainfall changes and “low confidence” that variations in tropical cyclones could be attributed to humanity’s relatively insignificant carbon emissions.
“Uncertainty in the sign of projected changes in climate extremes over the coming two to three decades is relatively large because climate change signals are expected to be relatively small compared to natural climate variability,” the draft report admitted. Some climate experts picked up the new cautious tone.
