The Alarming Effects of Climate Change and Floods in Pakistan
In August 2022, national rainfall reached 192.7 mm—3.43 × average (56.2 mm). Sindh saw 8.3× normal, and Balochistan 6.9× average precipitation. Such extreme rainfall coupled with melting glaciers triggered the catastrophic floods climate.copernicus.eu.
From June to October 2022, floods displaced some 33 million people (~12‑15% of population), destroyed over 565,000 homes, damaged 1.15 million more, and caused estimated US$40 billion in losses and $15 billion economic impact. At least 1,760 people died Wikipedia+1Wikipedia+1.
In mid‑2025, flash floods—fueled by a heatwave reaching up to 48.5 °C and intense monsoon rains—killed over 200 people, including nearly 100 children, and injured hundreds in Punjab, KP, and Gilgit‑Baltistan.

Climate models show that 5‑day rainfall amounts in Sindh and Balochistan during 2022 floods were 75% higher due to climate change. Sixty‑day totals were 50% higher—a clear example of human amplification of natural extremes UNICEF USA+1#ThinkLandscape+1.
Rapid glacial melt has formed unstable lakes. One‑third of projected river flows may decline over 50 years, while flood risk rises. Projected future flood peaks under SSP5‑8.5 scenario may reach 6,777 m³/s for 100‑year events IWA Publishing. Villagers wade through floodwaters in northern Pakistan as climate-driven monsoon rains and glacial melt submerge their homes — a haunting glimpse into the nation's unfolding climate crisis.
Pakistan launched the 4RF framework—Resilient Recovery, Rehabilitation & Reconstruction Framework—to build back stronger after the 2022 floods. At the 2023 International Conference on Climate Resilient Pakistan, the country raised over US$10 billion, surpassing its target World Economic Forum+1Wikipedia+1.

Hydrological models forecast deeper floods—up to 48 m water depth under high emissions scenarios. Future flood volumes could exceed historic levels significantly, demanding targeted flood protection in high-risk zones IWA Publishing.

Restoring floodplains, reforestation, sustainable river management, and improving drainage systems can reduce flood risk while supporting biodiversity and livelihoods.
Reconstructing resilient health infrastructure, training medical staff for flood outbreaks, and strengthening disease surveillance systems are vital. Early warning and preventive nutrition support can curb post-disaster famine and outbreaks. What caused the 2022 floods?
Heavy monsoon rainfall (up to 8.3× average) and accelerated glacial melt triggered floods, worsened by climate change AP News+2The Guardian+2Human Rights Watch+2. How many people were affected in 2022?
Approximately 33 million people affected; 1,760 deaths; over 1.7 million homes destroyed or damaged; US$40 billion in total damage Wikipedia+1Wikipedia+1. Has flood intensity increased due to climate change?
Yes. Extreme rainfall intensities in worst-hit regions increased by ~75%, and longer‑period rain totals by ~50% compared to pre‑industrial climate IWA Publishing+1Wikipedia+1. Are there more risks in 2025?

Pakistan stands at the frontline of climate change's impact, with climate-induced floods devastating communities across the country. To confront this, urgent action is needed: Invest in early warning systems and nature-based flood mitigation .
. Strengthen public health infrastructure to respond to post-disaster outbreaks.
to respond to post-disaster outbreaks. Channel international funds toward climate resilience, not just recovery .
. Support loss-and-damage mechanisms to deliver climate justice.
Only a coordinated mix of science-based planning, grassroots adaptation, and equitable international support can protect Pakistan's people and future.

I was motivated to write this article by my professor, Professor Dr. Sobia Masood , Chairperson of Psychology Department, Rawalpindi Women University, whose encouragement inspired me to explore the topics continue writing. Her support reminded me that our words can spark awareness, empathy, and change. I hope this piece contributes to that purpose.

Heavy rain and flash floods batter US east coast with emergency declared in New York
Heavy rain and floods are hitting parts of the US east coast, causing flight cancellations and leaving drivers stranded in cities including New York. A total of almost 50 million people in the US are under flood watches, and states of emergency have been declared in New Jersey and , with state workers being sent home early. Airports in NYC, New Jersey and Philadelphia all reported significant flight delays and cancellations as the severe weather arrived on Thursday. Flights leaving all three of New York's largest airports are delayed, and all inbound flights are being held until conditions improve, Sky's US partner NBC News reports. Planes have also been grounded at airports in and Baltimore, Maryland. A major highway in the New York borough of Queens was closed in both directions, with traffic cameras and social media posts showing vehicles stranded in deep water. Officials in New York have warned that heavy rain could also flood parts of the subway and basements. People living in basements have been urged to move to higher floors and New Yorkers are being asked to avoid travel until Friday afternoon. The commuter rail system into suburban Long Island suspended trains on one of its busiest lines as officials pleaded with people to stay at home. "Stay home this evening unless it's absolutely necessary for you to go out," Nassau County executive Bruce Blakeman told Long Island residents. Read more: Tornado warnings were also in place in New Jersey, and while no twisters were reported, more than 6,000 electricity customers have been left without power. In some parts of Pennsylvania, National Weather Service warnings said there could be up to three inches of rain in just one hour, and a downpour flooded the streets of Reading. Up to four inches of rain have fallen in parts of Maryland and Washington DC, and the heavy rain is continuing, NBC reports. Flood and severe thunderstorm watches are in effect for parts of Pennsylvania until Friday, with four to six inches of rain possible in some areas.

Fireflies are lighting up summer skies. But the glowing bugs are still on the decline
NEW YORK — Fireflies are lighting up summer evenings across the U.S. Northeast, putting on dazzling shows in backyards and city parks. There's no official count, but experts say a particularly wet spring may have created the ideal conditions for young fireflies to grow into adults to set summer nights aglow .
