«Glaciers in higher colder mountainous
regions will be slower to melt even as temps rise, the lower tundra areas will respond more quickly to such changes and this is shown by the quicker responses in tree line to the lesser

It is worth noting that wildfire incidences like this one, which are occurring across the globe now more frequently, with greater severity, and causing more damage than ever, also function as yet another feedback loop in regard to ACD: As the planet
warms, arid
