Climate Tricks 87, 'Man-made' CC causes less storms and more storms

The usual argument by climate alarmism movement is that less rain or more rain, less flood or more flood, less storms or more storms, they are all "proof" of man-made climate change (CC). So regardless of the weather and climate, we should keep sending more money to the UN, governments, big international NGOs, etc. and they will "fight" CC. Scam.

No trend of "worsening" storms, hurricanes, typhoons. Either declining trend or a simple natural cycle of more storms followed by less storms and so on.

Four charts below about Tropical cyclone (TC) accumulated cyclone energy (ACE), from Dr. Ryan Maue, https://policlimate.com/tropical/.

1. Global Hurricane Frequency (all & major) -- 12-month running sums. The top time series is the number of global tropical cyclones that reached at least hurricane-force (maximum lifetime wind speed exceeds 64-knots). The bottom time series is the number of global tropical cyclones that reached major hurricane strength (96-knots+). Adapted from Maue (2011) GRL.


2. Last 4-decades of Global and Northern Hemisphere Accumulated Cyclone Energy: 24 month running sums. Note that the year indicated represents the value of ACE through the previous 24-months for the Northern Hemisphere (bottom line/gray boxes) and the entire global (top line/blue boxes). The area in between represents the Southern Hemisphere total ACE.


Last 4-decades of Global Tropical Storm and Hurricane frequency -- 12-month running sums. The top time series is the number of TCs that reach at least tropical storm strength (maximum lifetime wind speed exceeds 34-knots). The bottom time series is the number of hurricane strength (64-knots+) TCs.


Last 4-decades of Global Tropical Storm and Hurricane Accumulated Cyclone Energy -- Annual totals. The Southern Hemisphere tropical cyclone season occurs from July-June each calendar year. The graph is constructed such that SH annual value for July 2014 - July 2015 is positioned in 2015.
