World at risk of entering Hothouse conditions even if emission targets are met

As the world experiences unprecedented heatwaves nearly all over, a new report by scientists says the world is at risk of entering “hothouse” conditions where global average temperatures will become four to five degrees Celsius higher even if emissions reduction targets under a global climate deal are met.

Temperatures have risen about 1.1°C (or about 2 degrees Fahrenheit) above pre-industrial levels. Virtually the entire scientific community has concluded that Earth’s temperature is climbing considerably faster than it did prior to the industrial era, and that greenhouses gases generated by human activities are the principal cause.

A new study published in the US Proceedings of the National Academy of Sciences (PNAS) on Monday said it is likely that if a critical threshold is crossed, it may lead to a cascading effect with several tipping points being crossed leading to abrupt change.

Such processes include permafrost thaw; the loss of methane hydrates from the ocean floor; weaker land and ocean carbon sinks; the loss of Arctic summer sea ice and the reduction of Antarctic sea ice and polar ice sheets, said the report.

“These tipping elements can potentially act like a row of dominoes. Once one is pushed over, it pushes Earth towards another,” said Johan Rockstrom, co-author of the report and executive director of the Stockholm Resilience Centre, according to media reports.

“It may be very difficult or impossible to stop the whole row of dominoes from tumbling over. Places on Earth will become uninhabitable if ‘Hothouse Earth’ becomes the reality,” he added.

A 2015 Paris climate agreement aimed to keep global warming below 2 degrees Celcius, compared with pre-industrial levels. But according to the report, the risk of tipping cascades could be significant at a 2C temperature rise — and could increase sharply beyond that point.

“This cascade of events may tip the entire Earth system into a new mode of operation,” warned co-author Hans Joachim Schellnhuber, Director of the Potsdam Institute for Climate Impact Research, according to a report by Al Jazeera.

“The feedback process becomes self-perpetuating after a critical threshold is crossed,” the study said. “The ‘earth system’ may be approaching a planetary threshold that could lock in a continuing, rapid pathway towards much hotter conditions — Hothouse Earth.”

Thus, even if humanity slashes greenhouse gas emissions in line with Paris climate treaty goals, the planet could overwhelm such efforts and irretrievably tip into a hellish ‘hothouse’ state.  Under such a scenario, the earth’s average temperature would stabilise 4 or 5 degrees Celsius above pre-industrial levels, rather than the 1.5 ° C to 2 ° C cap called for in the 196-nation pact.

As it is, the world is struggling to curb the man-made carbon pollution that amplifies the likelihood and intensity of deadly heatwaves, droughts and superstorms: climate change continues to outpace the transition to a green, clean global economy.

But that challenge will become exponentially more difficult if the earth itself gets into the act, the researchers said. Scientists from the Stockholm Resilience Centre, the University of Copenhagen, Australian National University and the Potsdam Institute for Climate Impact Research worked on the study.

They said that “Hothouse Earth” is likely to be dangerous to many and uncontrollable.

Rivers would flood, storms would wreak havoc on coastal communities and coral reefs would be eliminated – all by century’s end or even earlier.

Global average temperatures would exceed those of any interglacial period — meaning warmer eras that come in between Ice Ages — of the past 1.2m years. Melting polar ice caps would lead to dramatically higher sea levels, flooding coastal land that is home to hundreds of millions of people, reported Al Jazeera about the study.

The “carrying capacity” of a 4C or 5C degree world could drop to a billion people, co-author of the study Hans Joachim Schellnhuber has said previously.

Oppo is gearing up to introduce its Reno 15 lineup in India, with the series expected to focus heavily on enhanced imaging, performance stability and creator-friendly tools. The smartphone, which has already been launched in China, is anticipated to reach the Indian market in the coming weeks although the company has not yet shared an official date.

Expected price range in India

Industry estimates suggest the standard Oppo Reno 15 will fall in the upper-mid price bracket. While the Reno 15 Pro was launched in China at CNY 3,699 (roughly Rs 46,000), the Reno 15 base model is expected to be more affordable, likely between Rs 32,000 and Rs 38,000, depending on RAM and storage configurations.

Expected features and specifications

The Reno 15 series is expected to highlight Oppo’s improvements in sustained performance, camera capabilities and thermal management. Globally, the models run on ColorOS 16 and feature advanced cooling, particularly aimed at gaming and continuous live-streaming use.

For India, the upcoming Oppo Reno 15 is likely to offer:

  • A high-refresh-rate AMOLED display
  • Triple-camera setup with a primary sensor optimized for better low-light clarity
  • Secondary wide-angle and portrait cameras
  • Front camera with autofocus and AI-led enhancements for live streaming
  • Around 5,000mAh battery with fast wired charging support
  • AI-driven system optimization for smoother long-term performance

Design-wise, it is expected to follow the Reno 15 Pro’s flat-frame style, offering a slim profile, improved durability and brighter display output. With growing demand for creator-focused smartphones in the country, the Reno 15 is being positioned for users interested in mobile photography, vlogging and gaming.
