A Wild Solution for Climate Change

In addition to the physical impacts of climate change—the retreat of ice in most places, change in fire regimes, extreme weather events (droughts, major storms), sea level rise and ocean acidification, there are multiple biological impacts. The latter are no longer just modest changes in phenology and geographical distribution. The shift to accelerating change makes a strong case for limiting climate change to no more than 1.5° above pre-industrial temperature. That challenging goal can only be achieved by lowering greenhouse gas concentrations. Restoration of extensive historically degraded and destroyed ecosystems has the potential to substantially lower atmospheric CO2 concentrations—hence a “wild solution” to climate change.
