New paper shows the Holocene Climate Optimum ~6000 years ago was much wetter and warmer
A new paper published in Quaternary Science Reviews reconstructs the Indian Summer Monsoon, a "major global climatic phenomenon," over the past 18,000 years and finds the mid-Holocene Climate Optimum [HCO] in India was characterized by 20% more precipitation in comparison to the pre-industrial period ~1850. Most global precipitation records show a slight increase of precipitation since the pre-industrial period of only a few percent, thus the study suggests the Holocene Climate Optimum was considerably wetter and warmer than present-day climate, as also has been shown by hundreds of other paleoclimate papers finding the HCO was 2-3C warmer and wetter than currently, and thus the probability of drought in a warmer climate would tend to decrease, not increase as many alarmists have claimed.
