Looks like the pre-monsoon season is prolonging this time.

>⚠️ The EU's Copernicus climate service now projects the 1.5°C threshold will be crossed by May 2029. The UN's WMO puts the odds at 70%. This isn't a drill.

Most people hear "1.5 degrees" and think: that's nothing, I barely notice 1 degree in my house. But this isn't your thermostat. This is the average temperature of the entire planet — oceans, poles, tropics, everything. And the science is unambiguous about what comes next.

Here's the thing that really got me: in 2015 when the Paris Agreement was signed, the 1.5°C threshold was projected to arrive in 2045. That's 30 years. Plenty of time, right? Today, that projection is 2029. We burned through 16 years of runway in just one decade.

What crossing 1.5°C actually looks like:

🪸70–90% of coral reefs collapse. These reefs support a quarter of all marine species and billions of people's food supply. At 2°C, 99% are gone.

🌊Ocean warming doubles its current pace. In 2025, ocean heat content hit its highest level since records began in 1960, absorbing heat 18× humanity's total annual energy use — every single year.

🌀Hurricanes, droughts, floods — all intensifying. Warmer oceans fuel stronger storms. We saw this in 2025 alone with deadly floods across Australia, France, Algeria, India, China, and Ghana.

🌾Food and water security crumbles. Crop yields drop, fisheries collapse (U.S. East Coast faces a 20–30% fish harvest decline by 2060), and water scarcity spreads across already-stressed regions.

🦠Disease vectors expand. Malaria, dengue, and heat-stress illness spread into regions that never experienced them before as habitable zones shift.

🧊Arctic sea ice keeps shrinking. Arctic warming outpaces the global average. Sea ice in the Barents, Bering, and Okhotsk seas is projected to keep declining through 2029 and beyond.

>"If your face is about to slam into the wall at 100 miles per hour, it is sort of irrelevant if your nose is currently 1 millimeter or 2 millimeters from the wall."— Glen Peters, climate scientist, Norwegian CICERO Institute

The good news — and yes, there is some — is that every fraction of a degree still matters. 1.6°C is meaningfully better than 2°C. We don't fall off a cliff at 1.5°C. But this is an inflection point where risks compound, feedback loops kick in, and recovery becomes exponentially harder.

Scientists are clear: the solution is fast, deep cuts to fossil fuel emissions. The technology exists. The economics increasingly favor it. What's lacking is political will — and public pressure is one of the few things that creates that.

TL;DR: The 1.5°C warming limit will likely be crossed by 2029 — 16 years ahead of schedule. This means mass coral die-offs, stronger storms, food and water insecurity, and cascading ecosystem breakdown. It's not the end of the world, but it's a critical threshold that makes everything harder to fix. Share this. Talk about it. Vote on it. The window to act is still open — barely.

Being born and living my entire life in Mumbai, I am noticing that year after year the heat here is getting unbearable. To a point that it is outright life threatening to go outdoors anytime during the sun. I have never seen such dramatic and rapid change ever in my life earlier. Does anyone else have the feeling to leave India just because of this shitty climate? Am I the only one who feels that no one else cares around me because they are too busy in the "spirit of Mumbai" and the famous "chalta hai" and "adjust karo" mentality. I bet even if the average temperature crossed 60°C people will keep adjusting here. I know global warming is affecting the entire globe and not just India, but India is FAR MORE VULNERABLE to climate change yet nobody seems to bother when they are suffering themselves too. Maybe at one point it just becomes impossible to survive here and we might see a mass migration movement to north India or towards the west which would be catastrophic. What would be the consequences of such scenarios? I would genuinely love to discuss this and hear what do you guys think about this serious crisis knocking our doorstep?
