Climate crisis: What can trees really do for us?
Hindustan TimesBy Rob MacKenzie, Professor of Atmospheric Science, University of Birmingham & Rose PritchardPresidential Fellow in Social-Environmental Systems, Global Development Institute, University of Manchester: Forests are not nurtured, they have to fend for themselves. Carbon current accounts To find out, my colleagues and I at the University of Birmingham’s Institute of Forest Research use a free-air CO₂ enrichment facility. Forest carbon current accounts can hold carbon for decades, occasionally centuries, in their standing timber and roots and soil, tiding us over the 21st-century peak in atmospheric CO₂ – a carbon cashflow crisis caused by burning fossil fuels and deforestation. People and trees Scientific models have estimated how much tree planting or reforestation is needed to offset rising CO₂ in the atmosphere. Local foresters were also preoccupied with meeting tree planting targets, rather than nurturing the kinds of forests and trees which local people valued.
