When Ice Gives Way: Nepal’s Floods, Climate Change, and a Touch of Green Humour

It was a typical monsoon afternoon in the Kathmandu valley when the roar of water echoed from the mountains, drowning the quiet chatter of market stalls. Within minutes, villages downstream were under knee‑deep water, roads turned to rivers and families scrambled for higher ground. The culprit? A glacial lake outburst flood – a dramatic, and increasingly common, symptom of climate change gripping the Himalayas.

Glacial lake outburst floods, or GLOFs, happen when a moraine‑dammed lake perched on a glacier’s edge suddenly ruptures. The melt‑water that had been safely stored behind piles of rock and debris rushes downhill with terrifying speed, picking up sediment, boulders and, unfortunately, human lives. In Nepal this year, the flood took a particularly harsh turn, wiping out fields, bridges and, tragically, a handful of homes.

Scientists have long warned that warming trends are inflating these high‑altitude lakes. A study by the International Centre for Integrated Mountain Development (ICIMOD) notes a 30 % rise in lake surface area across the Nepalese Himalaya over the past two decades. As temperatures climb, glaciers recede, exposing new basins that fill with melt‑water – a perfect recipe for disaster if the natural dams fail.

For the people living in the valleys, the physics feels distant; what matters is the sudden surge of cold, mud‑laden water slamming into their doorsteps. “We heard a loud bang, then the water rose like a wall,” recounts Lakshmi Thapa, a farmer from the Lamjung district. “We ran, we prayed, we lost our cattle.”

While emergency crews worked tirelessly – shoring up makeshift levees, rescuing stranded children, and delivering food parcels – another, quieter rescue was underway on a different battlefield: the public imagination. Rohan Chakravarty, a cartoonist based in Nagpur, has been turning the grim reality of GLOFs into a series he calls ‘Green Humour’. His sketches feature anthropomorphic glaciers sighing under the weight of carbon emissions, and rivers muttering, “You promised me a calm life, but you gave me a wild ride!”

Chakravarty’s work may seem light‑hearted, but it serves a purpose beyond laughter. By distilling complex climate science into relatable visuals, he helps bridge the gap between researchers and the everyday citizen. In one panel, a mountain goat wearing a safety helmet warns, “Don’t ignore the cracks – they’re louder than you think!” The caption reads, “Glaciers are melting, but the jokes are still fresh.” It’s the kind of humor that sticks, prompting readers to pause and reflect.

Environmental NGOs have welcomed the series, sharing the cartoons on social media to raise awareness about GLOFs and the urgent need for climate‑adaptation measures. Some local governments have even used Chakravarty’s illustrations in community workshops, teaching villagers how to spot early warning signs – like sudden rises in lake water levels or fissures in moraine walls.

But jokes alone won’t stop the floodwaters. Experts argue that a multi‑pronged approach is essential: continuous monitoring of glacial lakes using satellite imagery, early‑warning systems installed in vulnerable catchments, and community‑led disaster preparedness drills. International funding, too, must be mobilised to reinforce infrastructure – bridges that can withstand surge flows, and evacuation routes that stay clear even when roads are washed away.

There is a growing consensus that the Himalayas are a climate sentinel. Their rapid response to warming offers a stark preview of what could happen elsewhere. If policymakers ignore these warning signs, the next outburst could be far larger, affecting not only Nepal but downstream nations like India and Bangladesh.

In the meantime, Chakravarty continues to sketch, his pen dipping into both satire and sorrow. One of his recent drawings shows a melting glacier sending a postcard to the Earth: “Wish you were here – it’s getting hotter!” It’s a gentle nudge, reminding us that the planet’s humor is fading, and the stakes are no longer a punchline.

So when the next rumble rolls down the hills, remember the stories behind the water. And perhaps, pause a moment to read a cartoon that, in its own quirky way, asks the same question we should all be asking: what are we doing to keep the ice from saying goodbye?
