Analysis finds the frequency and intensity of tropical cyclones decrease with warming

A new report from SPPI and CO2 Science:

Have hurricanes of the Pacific Ocean become more numerous and intense over the past century or so, in response to what climate alarmists typically describe as unprecedented global warming? To provide a firm foundation for answering this important question, this summary contains brief synopses of several real-world (as opposed to climate-model) studies that have appeared in the peer-reviewed scientific literature over the past few decades and have focused on this important question.
In stark contrast to the climate-alarmist claim that tropical cyclone numbers and strength tend to increase with global warming, these real-world observations suggest that, if anything, just the opposite appears to be occurring.
An increase in local SST (Sea Surface Temperature) does not lead to a significant change of the number of intense TCs (Tropical Cyclones) in the WNP(Western North Pacific), which is contrary to the results produced by many of the numerical climate models.
The entire 20th century had but one such intense cyclone (and that was in its early stages in 1911), while there were as many as seven intense tropical cyclones during the global chill that prevailed between AD 1600 and 1800.
In spite of this “remarkable warming,” the two researchers determined that “the frequency of TC against the background of global warming has decreased with time.”
In concluding this summary, and in light of the several sets of hard evidence from the real world of nature that comprise it, as opposed to the theoretical constructs from the virtual world of climate models, it is readily evident that the climatic implications of the two different worlds are truly worlds apart from each other.
