The Arctic is Getting Greener, but the Change is Lower than Expected

The Arctic is Getting Greener, but the Change is Lower than Expected Written by AZoCleantechApr 30 2021 There was a hope that as more plants start to grow in Arctic and boreal latitudes as our warming climate makes those regions more hospitable for plants, those photosynthesizing plants would work to help sequester the atmospheric carbon dioxide that helped them flourish in the first place. But new research led by scientists at UC Irvine and Boston University, out in Nature Climate Change, suggests that all the new green biomass is not as large a carbon sink as scientists had hoped. What does greening really mean? Can we really trust it to save us from climate change? said Jon Wang, an Earth system scientist at UCI who the led the work alongside BU Earth & Environment professor Mark Friedl.

The Arctic is greening, but not enough to help climate change, study finds

  TORONTO While the Arctic is growing greener with climate change, scientists warn that it is not greening fast enough to absorb very much carbon dioxide. According to new research from scientists at Boston University and University of California Irvine (UCI), there was hope that as more plants start to grow in the Arctic with the climate warming, those plants would be able to help photosynthesize the atmospheric carbon dioxide that helped them grow in the first place. However, scientists now say the greening is not nearly enough to curb global warming on the continent. The study, published Thursday in Nature Climate Change, suggests that new green biomass in the Arctic is not as large a carbon sink as previously thought.

The Arctic s greening, but it won t save us

A big question is: What ll happen to the carbon that s currently stored in these forests as above-ground biomass in the face of a changing climate?

Fires Are Keeping Arctic Forest Growth from Offsetting CO2 Release

Scientists hoped new forest growth would trap CO2 released by melting ice and permafrost due to global warming, but a new study shows it’s not enough because wildfires are reducing forest growth.

(Maja Suslin/TT via AP) (CN) Climate change is causing the Arctic to get greener, but those thicker forests will not help battle climate change as well as was hoped, a new study says. Scientists believed that although the warming atmosphere is melting Arctic ice and permafrost, and therefore releasing sequestered carbon dioxide, the warmer temperatures could spur more plant growth in the same area that might be able to offset the CO2 releases.
