Climate-change impacts on natural disturbances have affected ecosystems  , and these impacts will increase with future climate change . Facilitated by warm, dry conditions, 'mega-disturbances' and synergies between disturbances that include wildfires, insect and disease outbreaks, and drought-induced tree mortality continue to affect large areas of North America , overwhelming adaptive capacities of species and degrading ecosystem services . This era of mega-disturbances is expected to become more widespread and severe in coming decades , with potentially significant impacts on ecosystems . Effects include widespread tree mortality  and accelerated ecosystem transformation  .
