Recent research found that natural solutions like improved management of
forests, wetlands, grasslands and agricultural lands can remove about 5.6 GtCO2e of carbon per year by 2030 — a figure equivalent to total

In addition to local weather patterns, shaped by climate change, a review of Chile's wildfires published in the
Global and Planetary Change journal warned that the «pattern, frequency and intensity» of wildfires in the country «has grown at an alarming rate» in
recent years, partly because of intensive
forest management practices that have led to a large amount of flammable fuel in the country's
forests.
Recent multi model estimates based on different CMIP3 climate scenarios and different dynamic
global vegetation models predict a moderate risk of tropical
forest reduction in South America and even lower risk for African and Asian tropical
forests (see also Section 12.5.5.6)(Gumpenberger et al., 2010; Huntingford et al., 2013).»
