sixth assessment report (AR6) of Intergovernmental Panel on Climate Change (IPCC).
PART-1
the Intergovernmental Panel on Climate Change (IPCC) released the first part of its Sixth Assessment Report (AR6) titled Climate Change 2021: The Physical Science Basis.
The report insisted that, the average surface temperature of the Earth will cross 1.5 °C over pre-industrial levels in the next 20 years (By 2040) and 2°C by the middle of the century without sharp reduction of emissions.
The last decade was hotter than any period of time in the past 1,25,000 years. Global surface temperature was 1.09°C higher in the decade between 2011-2020 than between 1850-1900.
Carbon dioxide (CO2) Concentrations are the highest in at least two million years. Humans have emitted 2,400 billion tonnes of CO2 since the late 1800s.
Most of the emission is caused by human activities, particularly the burning of fossil fuels( vehicular emission). In order to fulfill its commitment toward economic development human have polluted and destroyed ecology.
Sea level has risen by the multiple to three compared to 1901-1971, Arctic sea is continuously melting at unprecedented rate.
