NEW DELHI: Senior Congress leader Jairam Ramesh on Sunday flagged concerns over global climate change and said the world needs tough actions now, not grandstanding slogans for 2050 and beyond.

The former environment minister said 60 scientists from reputed institutions from across the world, including two from India, have just published their third annual update of indicators of global climate change.

Ramesh noted it is a comprehensive analysis.

"There is a faint signal of hope in the update in that the rate of increase in carbon dioxide emissions over the last decade has slowed compared to the 2000s. But global mean sea-level rise continues to accelerate," Ramesh said on X, citing the analysis.

"The earth's energy imbalance, which represents the difference between the radiative forces acting to warm the climate on the one hand and to oppose the warming on the other, has increased significantly," he said.

Most worryingly continued emissions of all greenhouse gases at current levels would cause human-induced global warming to reach the critical 1.5 degrees Celsius in about five years, Ramesh said.

The present policies of the US could well advance this tipping point, he said and added that already 2024 was the hottest year on record.

"The world needs tough actions now, not grandstanding slogans for 2050 and beyond," Ramesh asserted.

He also shared the link to the analysis.
