How policies can improve air pollution?

Here, one example for this. The carbon monoxide pollution has been decreasing in India for the past 10 years, mostly due to the relevant government policies.

This is also the first detailed analysis of CO pollution in RURAL INDIA.

FORMALDEHYDE and CANCER RISK in INDIA

Spatial variability: Elevated formaldehyde (HCHO) levels occur in industrial hubs, coastal regions, and agricultural zones across India.

Cancer risk hotspots: Northern Indo-Gangetic Plain, Northeast India, and Kerala show the highest cancer risks (up to 81,280 cases per million).

Emission sensitivity: Reducing NOₓ emissions by 25% and 50% lowers cancer risks by 2.60% and 6.74%, respectively.

Policy implication: Strong regulation of HCHO emissions is crucial to reduce health risks, especially in areas with limited healthcare access.

Contribution of Arabian Sea cyclone-driven rainfall to the total rainfall on land and ocean

Its an open access article. Grab a copy:

This study examines the contribution of tropical cyclones (TCs) originated in the Arabian Sea (AS) to the seasonal and annual rainfall in AS and India land regions in the period 2000–2020. A total of 32 TCs are occurred and considered during the period, focusing on rainfall within 300 km radius fr...

Increasing Ecological droughts in India !

Here is the first comprehensive investigation of ecological droughts, their drivers, and their implications during the Indian Summer Monsoon (ISM).

Our analysis reveals that ecological droughts have been increasing across ecologically fragile regions, including pristine forests and croplands, leading to a decline in vegetation health across India.

The rise in multiple forms of aridity, together with shifts in the Indian Summer Monsoon associated with ocean warming and intensified anthropogenic pressures, has contributed to the increasing occurrence and severity of ecological droughts across the country.

The study is published in Communications Earth and Environment (from Nature Group). Its an open access article.

Meteorological aridity and, indirectly, ocean warming contribute to increased ecological droughts in India during the Indian summer monsoon by about 24% and 18%, respectively, according to an analysis of satellite vegetation data over the period 2000–2019 using machine learning.

https://news.mongabay.com/2025/04/ground-level-ozone-pollution-poses-growing-threat-to-planetary-health/

Kilometers above the Earth’s surface, the ozone layer protects humanity and all life from the sun’s harmful ultraviolet rays. But in the troposphere, at ground level, this gas can wreak havoc on planetary health in myriad ways. As temperatures increase due to climate change, the ozone problem is...
