Extreme weather risk high despite Paris Agreement: Study

The study published in the journal Science Advances showed that meeting the Paris Agreement's goal was likely to reduce the area of the globe that experiences greater than threefold increases in the probability of record-setting events

  • The Paris Agreement saw nearly all the countries in the world set an aspirational target of capping global warming at 1.5 degrees Celsius
  • The researchers found that if countries kept their minimum commitment to limit global warming to 2-3 degrees Celsius

Meeting the Paris Agreement’s goal of keeping the global-scale warming this century to less than 2 degrees Celsius could still lead to extreme weather events compared to the present, claims a study.

The Paris Agreement saw nearly all the countries in the world set an aspirational target of capping global warming at 1.5 degrees Celsius, Xinhua news agency reported on Thursday.

But even if the target was reached, “we still will be living in a climate that has a substantially greater probability of unprecedented events than the one we’re in now”, said Noah Diffenbaugh, a climate scientist at Stanford University and the paper’s lead author.

The study published in the journal Science Advances showed that meeting the Paris Agreement’s goal was likely to reduce the area of the globe that experiences greater than threefold increases in the probability of record-setting events.

However, even at this reduced level of global warming, the world was still likely to see increases in record-setting events compared to the present.

The researchers found that if countries kept their minimum commitment to limit global warming to 2-3 degrees Celsius, it was still likely to result in a more than fivefold increase in the probability of record-breaking warm nights over approximately 50 percent of Europe, and more than 25 percent of East Asia.

A 2-3 degree global warming would also likely result in a greater than three-fold increase in record-breaking wet days over more than 35 percent of North America, Europe and East Asia, the study said. (IANS)

Dusshera In Delhi Casts A Dark Blanket, Air Quality Worsens

The National Capital and the regions around it continue to suffer a “very-poor” air quality on Friday, which according to experts, may worsen due to combined effects of Dussehra and meteorological reasons such as low winds in Delhi.

Between 6pm to 8pm, over 48 areas across the National Capital Region — 36 from Delhi alone — suffered ‘very poor air-quality’ with pollutants registering over four times the national safety standards.

Weather analysts say this may worsen as Delhi currently has very light variable winds with no definite directions, which is likely to help in aggregating the pollutants.

“Delhi has a negligible wind speed and morning temperatures are low. Also, many effigies were burnt across the region on Dussehera. This will push up the pollution levels,” said Mahesh Palawat, director private weather forecasting group, Skymet.

The air-quality was already ‘severe’ at Anand Vihar in east Delhi and Rohini in north Delhi, Bawana in northwest Delhi, Mundaka in West Delhi and Bhiwadi in Rajasthan, acoording to the real-time monitoring taken up around 8pm by Central Pollution Control Board (CPCB).

The average presence of major pollutant PM2.5 or particle with diametre less than 2.5mm, was 129 unit across Delhi-NCR and 133 units in Delhi, which is more than twice the national safe limits. Rohini was the most polluted with PM2.5 concentration at 166 units, about three times the safe limits.

The permissible range or PM2.5 is 60 as per national standards and 25 by the international standards.

At 4pm, the Air Quality Index (AQI) of Delhi was 276 marked ‘poor’ against ‘moderate’ mere 48 hours back.
