  • Avoiding Emissions from Destruction. Keeping warm land ecosystems intact avoids massive greenhouse emissions release from ecosystem clearing.
  • Avoiding Emissions from Drought and Wild Fire. Keeping warm land ecosystems intact keeps moisture cycling intact and thus reduces droughting and drought fires. Native animals also reduce drought fires.
  • Maintaining Ongoing Greenhouse Gas Absorption. Intact, heavily vegetated, native ecosystems on warm lands typically consume the most greenhouse emissions per acre, per year, of all ecosystems.
  • Avoiding Emissions from Economic Development. Keeping warm land ecosystems intact avoids emissions from would be economic development, such as those generated by motorized transport, new construction, cattle ranching, and crop farming.
  • Keeping the Hottest Parts of the Planet Cool. Intact, warm land ecosystems reduce solar heat gain where it’s most intense on Earth.
  • Local Heat Buffering Absorption. Intact, warm land ecosystems provide vegetative heat absorption and buffering locally.
  • Protecting Microclimate. Intact, warm land ecosystems self-maintain optimal microclimate and moisture recycling.
  • Avoiding Hot Spots. Keeping warm land ecosystems intact avoids the increase in local temperature that comes after their vegetation is removed.
  • Avoiding Super Heating and Micro Heating. Keeping warm land ecosystems intact reduces spike heating from drought fire and radiant heating from drought fire debris.
  • Protecting Regional and Global Rainfall Patterns. Keeping warm land ecosystems intact protects i) long-standing atmospheric moisture recharge for inland ecosystem irrigation and ii) long-standing teleconnections between land vegetation and the atmosphere which co-determine rainfall patterns all over the world.
  • Protecting Forest Canopies. Hot forest canopies provide cooling shade, cause cooling air and moisture circulation, and stimulate cooling low cloud formation and precipitation.
  • Avoiding Heat from Economic Development. Keeping warm land ecosystems intact avoids heat gain from would be economic development, such as heat from motorized machines, ecosystem clearing, and road and rooftop installation.
On lands, vegetation density increases rainfall [From Keys, et al, 2029].
