IPCC Mandate

IPCC’s role is…
to assess on a comprehensive, objective, openand transparent basis the scientific, technicaland socio-economic information relevant tounderstanding the scientific basis of risk ofhuman-induced climate change, its potential
impacts and options for adaptation andmitigation.

Key Principles
IPCC reports should be neutral with respect
to policy, although they may need to deal
objectively with scientific, technical andsocio-economic factors relevant to theapplication of policies.

SEVENTH ASSESSMENT CYCLE

Selected findings from IPCC AR6
1. Recent changes in the climate are widespread, rapid, and intensifying,
and unprecedented in thousands of years
2. It is indisputable that human activities are causing climate change,
making extreme climate events, including heat waves, heavy rainfall,and droughts, more frequent and severe
3. Unless there are immediate, rapid, and large-scale reductions ingreenhouse gas emissions, limiting warming to 1.5°C will be beyondreach
4. The climate we experience in the future depends on our decisions now

10SEVENTH ASSESSMENT CYCLE

Admirable, Exceptional and Intriguing Deliberation

Summary and Recommendation
1. With every additional warming, the Intensity and frequency of extreme events including heavy
precipitation, Tropical Storms are increasing and are projected to continue increasing.

SEVENTH ASSESSMENT CYCLE

2. In the Seventh Assessment Cycle (AR7), IPCC is committed to strengthen Inclusivity and Diversity
including promoting the enhanced participation of the experts from Global South including earlier
career Scientists, Young People in Climate Change and IPCC Process.
3. The AR7 provide opportunities for Early Career Scientists to Excel in Science and Innovation inrelation to Climate Change and also provide opportunities for enhancing Networking andCollaborations across levels.
4. We Encourage All Scientists and Experts including Early Career Scientists to strengthen
participation in Climate Change Science and IPCC Process, starting with active participation in theIPCC SRCCC, including preparing policy brief from the report.
