IPCC’s AR6: Synergy between Climate Change & Development Impacts

The UN’s climate science panel unveiled (part 1of) its Sixth Assessment Report (AR6) on Climate Change on Aug 9, 2021, the first since AR5 in 2014. This 3949 page report is called “The Physical Basis”. A 150 page Technical Summary and a 39 page Summary for Policy Makers has also been published, among other volumes. The World and Science has changed a lot in the intervening seven years. It provides projections for temperature and sea-level rises less than three months before the climate summit -Conference of Parties COP26-  in Glasgow-Scotland. After two weeks of virtual negotiations, 195 nations (including India) approved the Intergovernmental Panel on Climate Change’s (IPCC) comprehensive assessment of past and future warming on Aug 6, 2021 in the form of a “Summary for Policy Makers” (SPM). The text, vetted and approved line by line, word by word, paints a grim picture of accelerating climate change and dire threats.[i]

Dr. Roxy Mathew Koll: “Warming Indian Ocean means a Weakening Indian Monsoon”

AboveAll-India Summer Monsoon (June-September) Rainfall Anomalies during 1871-2015. Note that since 1950s, not only has the incidence of droughts increased, but rainfall in the excess of 10% has also decreased markedly Source: IITM Paper Interanual Variations of Indian Summer Monsoon

When it comes to Global Warming and Climate Change (not interchangeable terms), India and the world have witnessed a series of firsts in the past year. The last 11 months have been the warmest months in recorded history, each monotonously breaking a previous record[i]. In India, regions like Maharashtra including Marathwada have experienced back to back droughts, in addition to increasing frequency of Extreme Weather events like Hailstorms and unseasonal rainfall. Variability of Western Disturbances has increased, which is linked with extensive anthropogenic warming over Tibet[ii]. Our response to Climate Change and the challenges it poses has been far from satisfactory. There has been no impact of National Action Plan for Climate Change, due to the inherent problems in its inception[iii]. State Plans lay languishing for several years, without clear accountability and transparency[iv]. India’s INDCs (Intended Nationally Determined Contribution) indicate more harm than good.[v] Continue reading “Dr. Roxy Mathew Koll: “Warming Indian Ocean means a Weakening Indian Monsoon””
