Energy Imbalance and the Changing Dynamics of El Niño
Context A recent study highlights that the 2022 increase in Earths energy imbalance was largely driven by a shift from a triple-dip La Niña to a warm El Niño, combined with long-term climate change. Earths Energy Imbalance Study Earth’s Energy Imbalance (EEI) refers to the difference between incoming solar radiation and outgoing heat energy. When more heat is trapped than emitted, global temperatures rise.
District Cooling: A Climate-Smart Solution for India’s Urban Future
Context In the backdrop of rising temperatures and rapid urbanisation, district cooling is emerging as a climate-responsive and urban planning solution aligned with India’s sustainability goals. What is District Cooling? District cooling is a centralised system that supplies air-conditioning to multiple buildings through a network of insulated underground pipes.
India’s Net-Zero Pathway: Ambition, Investment, and Reform
Context According to the NITI Aayog’s Scenarios Towards Viksit Bharat and Net Zero, India can achieve net-zero emissions by 2070 while becoming a developed economy by 2047, but this transition will require massive financial and structural shifts. What is Net Zero? Net Zero refers to the state where the amount of GHGs released into the atmosphere is balanced by the amount removed over a given period.

It seeks to enable India’s transition toward a low-carbon economy, aligning with its net-zero commitment by 2070
Delhi to Earn Revenue from Carbon Credits'
Context Delhi government has announced that it has approved a framework for carbon credit monetisation. About Delhi government activities such as operating electric buses, plantation drives, promoting solar energy and waste management, will be used to generate carbon credits under the new policy. The reduction in emissions through these initiatives will be scientifically measured, registered as carbon credits, and sold in national and international carbon markets to generate revenue.
Warming of Earth’s Oceans
Context According to a study titled ‘Ocean Heat Content Sets Another Record in 2025’, found that the oceans absorbed more heat in 2025 than in any year since modern measurements began in the 1960s.
