Humans have 'nearly exhausted' earth's global warming limit, scientists say

"The remaining carbon budget available to humans is running out, according to new research. The 1.5C global warming limit which is the top amount of emissions that can be put into the atmosphere above pre-industrial levels is nearly exhausted according to the University of Exeter's Global Systems Institute study. And this year, fossil fuel carbon emissions are expected to hit record highs, increasing by 1.1 per cent globally. At the current rate, humans will have used up the 1.5C limit within four years spelling danger for future generations dealing with the repercussions of climate change."

"Professor Pierre Friedlingstein, who led the study said: "With carbon dioxide emissions still increasing, keeping global warming below 1.5C is no longer plausible. He explained: "The remaining carbon budget for 1.5C, 170 billion tonnes of carbon dioxide, will be gone before 2030 at current emission rates."

"It comes after a scorching summer as Londoners endured a gruelling four heatwaves, making 2025 the hottest summer on record. The stifling temperatures made for a busy season for the London Fire Brigade, who put out around 83 wildfires across the capital. The Mayor of London expressed his thanks to the London Fire Brigade after an intense and challenging' summer It marked a 32 per cent increase on 2024, despite being dwarfed by the summer of 2022, where 40C temperatures led to a whopping 207 wildfires. The worst wildfire this year was recorded in Dagenham in July, which saw 20 fire engines and 125 firefighters called to the scene. Sadiq Khan, the Mayor of London, expressed his gratitude to the service over the summer, saying: Our brave firefighters have been working incredibly hard this summer, tackling intense and challenging wildfires across London. The huge increase in wildfires this summer has shown how vital it is that we take collective action to tackle this growing threat to the capital."

The remaining carbon budget for limiting global warming to 1.5C is nearly exhausted. Fossil fuel carbon emissions are rising and are expected to increase by 1.1% globally this year, reaching record highs. At current emission rates, the remaining 1.5C budget of about 170 billion tonnes of CO2 will be depleted before 2030, and the 1.5C limit could be used within four years. A scorching summer produced four heatwaves and made 2025 the hottest summer on record in London, prompting around 83 wildfires and straining fire services. The worst wildfire required 20 fire engines and 125 firefighters, and city leadership called for collective action as temperatures climb.
