Opening
As per WMO, 40% of Arctic has lost its 40% of ice since 1975 acting as one of the tipping point in anthropo-cene destruction.
Body
Major drivers of arctic retreat
→ Global warming due to rise in GHG emissions fuelled by coal & oil
→ Urbanisation with increased use of AC, fridge etc.
→ Deforestation & Mining leads to high carbon emission
→ Vehicular emissions with rising automobile concentration leading to high N2O and SOx concentration
→ Agriculture has higher carbon footprint with rice & sugarcane production
Potential Impact
→ carbon emissions - 92 Billion Carbon likely to be emitted by 2100
→ Methane emissions - more than the total concentration of current CH4 levels
→ Rise of diseases - Ex Russian Anthrax breakage due to Arctic retreat
→ Geographizal changes like changes in ocean current movement, heating of seas, changes in AMOC et.
→ sea level rise - (IPCC) can lead to 1 cm rise by 2100
→ impacts indigenous population - loss of habitat
→ Positive Impacts
→ 22% of unexplored oil
→ rare earth metals in Arctic
→ new source of energy
→ less shipping time
Close
Arctic must be supported with collaborative efforts and SDG-13 targets of climate change must be met.
