Global Warming Accelerates: Could Exceed 1.5°C Limit by 2030

Why in news

A study by NASA and other agencies warns that global warming is accelerating significantly, potentially breaching the Paris Agreement's 1.5°C limit by 2030.

Background

Researchers adjusted five major temperature datasets to remove natural influences like El Niño and volcanic eruptions. The study found a statistically significant acceleration in warming since 2013-2014 with over 98% confidence.

Facts for Prelims

• S&TParis Agreement: International treaty aimed at limiting global warming to well below 2°C, preferably 1.5°C.
• FactThe study identifies a significant acceleration in global warming starting around 2013-2014.
• S&TEl Niño: A climate pattern describing the unusual warming of surface waters in the eastern tropical Pacific Ocean.

For Mains

Q. Discuss the implications of accelerated global warming on India's climate goals and the necessity of transitioning to low-carbon economies to meet the Paris Agreement targets.
