11,000 scientists in 153 countries declare climate emergency

In a paper published in the journal BioScience, 11,258 signatories (69 from India) declared Global Climate Emergency. They presented climate change trends and methods to mitigate the threat. The report was titled “World Scientists”

It is based on the scientific analysis of more than 40 years of publicly available data. It illustrates several key climate change indicators since the scientists from 50 nations met at the First World Climate Conference in Geneva in 1979.


  • The scientists present a list of measures called “Vital Signs” that better represent climate change. It includes measures of human activities that can change climate like air travel, meat production and fertility rate. These activities have been termed as backward steps that are worsening climate change further. In 20 years, the world fertility rate has reduced greatly claims the report.
  • They present 14 measures of impacts of climate change like number of extreme weather events, ocean heat content, ocean acidity, etc.
  • Massive energy efficiency and conservation practices to cut out “Neither use nor dig out fossils under the earth.”
  • The following are the six key objectives of the report
    • Replacing fossil fuels
    • Restoring and protecting ecosystems
    • Cutting pollutants like methane and soot
    • Eating less meat
    • Converting the economy to carbon-free
    • Stabilizing population growth

    How can eating less meat help in mitigating drastic climatic changes?

      The livestock sector — raising cows, pigs and chickens — generates as much greenhouse gas emissions as all cars, trucks and automobiles combined. Cattle ranchers have clear cut millions of square kilometers of forests for grazing pastures, decimating natural “carbon sinks.”
