#StephenHawking #theIndependent # 2007 .. Hawking warns: We must recognise the catastrophic dangers of climate change. Climate change stands alongside the use of nuclear weapons as one of the greatest threats posed to the future of the world, the Cambridge cosmologist Stephen Hawking has said. Professor Hawking said that we stand on the precipice of a second nuclear age and a period of exceptional climate change, both of which could destroy the planet as we know it.. #ClimateChange #NuclearWeapons .. https://t.co/PwSsUN5rZR

Ocean waters in the South-West Pacific are becoming hotter and more acidic, harming economies & marine ecosystems. Sea level rise is threatening coastal communities & low-lying island nations.

There was a time when extreme heat was relatively rare.

But not anymore.

Heatwaves, which are already responsible for almost 500,000 deaths a year, are becoming more frequent, more intense and more dangerous.

To help, here are nine ways to stay cool when the temperatures spike:

“The Arctic is currently warming at four times the rate experienced by the rest of the planet. But the Antarctic has started to catch up, so that it is already warming twice as quickly as the planet overall.” https://t.co/gTDinE6ClH

To say El Niño is at record intensity for July is really an understatement. It’s a full .6°C/ 1.1°F ahead of the old record in 2015 in the main ENSO 3.4 region. That’s immense… It’s 1.95°C above the 1990-2020 average already. So just a hair below “Super” (+2C) already… 🧵 1/

Nino 3.4 SST is now up to 3.63 SD above the 1991-2020 baseline, about 1-in-7000 in the absence of anthropogenic warming.

"An increasing number of scientists think we have let the climate crisis fester for so long that our only hope to stave off ever-intensifying catastrophes is to use technological interventions."

Global sea-surface temperatures are at 21.00°C, and have now set a new daily record high for the 33rd day in a row, more than 0.08°C above the previous record high, set in 2024.

In 1985, Carl Sagan told Congress that continuing to burn fossil fuels will increase global temperature, cause climate change, melt glaciers and ice sheets, and cause sea level rise. Imagine if we had listened to him them.

Climate finance isn’t charity, it’s an investment in global stability and a livable planet.

From funding clean energy to drought-resilient seeds for farmers, it cuts emissions and strengthens communities.

Climate change is making floods, heatwaves, and storms more dangerous.

Early warning systems help predict these risks and alert people in time to act, saving lives, homes, and livelihoods.

💰 The cost advantage of #renewables over fossil fuels continued to widen in 2025. More than 90% of new renewable power capacity added globally was cheaper than the lowest-cost new fossil fuel alternative. See key findings in @IRENA's infographic➡️ https://t.co/4MD9uK3wK7

This is what a +3.9˚C El Niño could look like at its peak in December, according to new ECMWF data.

It would be the strongest El Niño on record by a wide margin.

[Ben Noll @BenNollWeather]

Breaking: El Niño intensity forecasts have trended stronger — again.

Every forecast scenario in the new ECMWF outlook shows the strongest El Niño on record this year, with ocean temperatures peaking 3.3˚C to 4.4˚C above average in the central equatorial Pacific in December.
