Sorry, I couldn't find a better community.

A while ago, maybe one or two months, someone shared a link in a comment that led to a site with a very thorough table of phone models (even obscure ones) with columns for whether they had VoLTE support, or whether they were blocked on the Telstra network.

I didn't think of saving it, and I can't find it anymore in my browsing history :( Does it ring a bell to someone?

Thanks in advance!

Sydney (AFP) – Australia's tropical rainforests are among the first in the world to start emitting more carbon dioxide than they absorb, scientists said Thursday, linking the "very concerning" trend to climate change.

The world's rainforests are typically thought of as crucial "carbon sinks" -- sucking huge quantities of planet-heating emissions from the atmosphere.

Some models predict that increased carbon dioxide in the atmosphere could boost forest growth by offering trees more of the basic fuel they need for photosynthesis.

But new research found extreme temperatures have instead caused more forest death than growth, with rainforests in Australia's northern tropics becoming net carbon emitters.

"This is the first analysis to show this pattern occurring for natural undisturbed forest and as a persistent pattern over many years," senior author of the research Patrick Meir told AFP, describing the results as "very concerning".

The researchers pored through records charting the growth of Queensland's rainforests over almost 50 years.

They found that around the year 2000 they began emitting more carbon dioxide from the decay of dead trees than was being taken in and stored by growing trunks and branches.

Modelling showed the main cause was extreme temperatures linked to climate change, and its related effects on the moisture in the atmosphere and drought. Cyclones, which are expected to increase in intensity with climate change, also had an impact.

The findings are in line with some research on the Amazon that showed growing tree deaths weakening the forest's carbon storage capacity, said David Bauman, a research scientist at the French National Research Institute for Sustainable Development and second author of the study.

"So in that sense our result is not surprising, but the timing... happened earlier than we expected and the effects of the likely climatic drivers (high temperature, drought) are stronger than we expected," he told AFP.

The study, published in the peer-reviewed journal Nature, suggests other rainforests could experience the same shift, but the authors warned more data and research was needed.

"It appears that all tropical forests are likely to respond fairly similarly," said Meir, but "the exact mechanisms and timings for different regions will differ."

The findings should ring alarm bells, said Melanie Zeppel, an expert on forest carbon who was not involved in the study.

"This study shows that impacts of climate change on forest carbon are more severe than previously reported," said Zeppel, associate director at climate change investment firm Pollination.

"Immediate action on climate change must be a key priority," she told AFP.

The study's authors cautioned that some unknowns remain.

Their work focused on branches and tree trunks, but roots and soil also play a role in carbon absorption and emission which has not yet been fully quantified.

Still, the patterns observed are clear, and "indicate that the challenge to limit global warming to well below 1.5 degrees Celsius has become both more urgent and more difficult," said Bauman.

Despite its growing vulnerability to climate-linked natural disasters, Australia remains one of the world's biggest exporters of gas and thermal coal.

Australia's carbon dioxide emissions per person are among the highest in the world, World Bank figures show.

Global emissions have been rising but need to be almost halved by the end of the decade to limit warming to safer levels agreed under the 2015 Paris climate agreement.

The increase in the amount of carbon dioxide in the atmosphere last year was the biggest ever recorded, the United Nations said this week.

At Panchsheel Inter College in Uttar Pradesh, students now study inside a new school wing built not from concrete or traditional brick, but from sugarcane. The innovation was born at the University of East London (UEL) and its creators argue it could reshape how buildings are made and how the planet pays for it.

Sugarcrete combines the fibrous residues of sugarcane, called bagasse, with sand and mineral binders to produce lightweight, interlocking blocks. Lab tests show that Sugarcrete has strong fire resistance, acoustic dampening, and thermal insulation properties. It’s been tested to industrial standards and passed with flying colors. In terms of climate impact, the material is a standout. It’s six times less carbon-intensive than standard bricks, and twenty times less than concrete, by some estimates.

Yet the real excitement doesn’t only come from what Sugarcrete is, but how it’s made and used. It is purposely ‘open access’ in order to establish partnerships to produce new bio-waste-based construction materials where sugarcane is grown. Unlike conventional building materials locked behind patents, Sugarcrete can be made by anyone with the right ingredients and basic manufacturing tools. That choice decentralizes construction innovation, allowing small-scale producers — especially in the Global South — to lead.

Or plant? Sorry if only tangentially related! Second time I don't notice any bites, just itching and after a day or two the monstrosity pictured appears and stays for like a week :( Tropical North Queensland.
