This is an excellent discussion of the contributions that Millan made to highlighting the role that inappropriate vegetation management has caused on the water cycle. I look forward to hearing more on this!

Good to hear from you, Roger. Yes, Alpha Lo has made an excellent contribution. You may enjoy his series on bioprecipitation and aerosols: https://climatewaterproject.substack.com/p/bacteria-make-rain-bioprecipitation

I'll make sure to pass on your paper, which I look forward to reading as well. It's something I've always wondered about. When I first read about desiccation of the cloud forests, it was portrayed as caused by CO2 emissions. Later, when I began learning about land change, I began to wonder about the role of deforestation, and now can learn more from your paper. Thank you.

Here is one of our papers which supports his seminal conclusions

Nair, U.S., R.O. Lawton, R.M. Welch, and R.A. Pielke Sr., 2003: Impact of land use on Costa Rican tropical montane cloud forests: 1. Sensitivity of cumulus cloud field characteristics to lowland deforestation. J. Geophys. Res. - Atmospheres, 108, 10.1029/2001JD001135.

Great article, Rob. Thank you.

Here is another study area that further confirms the conclusions of the pioneering work of Millan. We found a significant decrease in summertime convective rain due to land conversion. The terrain is flat so the signal is easier to explain.

Marshall, C.H. Jr., R.A. Pielke Sr., L.T. Steyaert, and D.A. Willard, 2004: The impact of anthropogenic land-cover change on the Florida peninsula sea breezes and warm season sensible weather. Mon. Wea. Rev., 132, 28-52.http://pielkeclimatesci.wordpress.com/files/2009/10/r-272.pdf
