Ribeirão Preto completa 170 anos com um rico patrimônio histórico. O g1 preparou um roteiro com 12 locais que contam a história da cidade, desde a época dos barões do café até a chegada dos imigrantes.
Researchers are testing a geoengineering method in Cambridge Bay, Canada, to refreeze Arctic sea ice. The Real Ice project pumps ocean water onto the ice surface, thickening it and reflecting more sunlight. While controversial, it's a research effort to explore potential solutions to climate change.
France and other nations rebuked the US at an Antarctic Treaty meeting for avoiding the term 'climate change', preferring specific environmental issues. The US cited a need for action-oriented discussions, but conservationists and experts criticized the stance as out of step with global consensus.
The Biodiversity Heritage Library (BHL), a digital archive of natural world literature, has made over 64 million pages freely available. Despite its crucial role in scientific research and understanding biodiversity crises, BHL faces funding cuts and may cease operations by 2027.
Over 13,000 seal pups have died on Australia's Heard Island due to H5N1 bird flu, with high mortality rates confirmed among penguins, seals, and petrels. The virus likely spread from French subantarctic islands, marking its eastward movement around the region. Australia is increasing preparedness for potential mainland incursions.
Hyundai Motor Group will implement a clean hydrogen energy system at South Korea's Antarctic research station, reducing reliance on diesel generators. The system converts surplus solar energy into hydrogen, which is then used to produce electricity via fuel cells when solar power is limited.
Antarctica's harsh environment has led to numerous unexplained deaths and disappearances over decades. From a young Chilean woman on Livingston Island to Scott's doomed expedition and accidents involving crevasses and storms, records are often fragmentary, leaving many events without clear closure.
Antarctica's west coast is experiencing a severe deficit of winter sea ice in the Bellingshausen Sea, with an area the size of France missing. This alarming trend raises concerns for penguins, marine life, and global sea levels, and may have intensified a recent heatwave on the continent.
Scientists detected iron-60, a radioactive isotope from ancient supernovae, in Antarctic ice up to 80,000 years old. This suggests Earth is still being showered by debris from stellar explosions millions of years ago, indicating our planet is traveling through a cloud of cosmic dust.
An area of Antarctica comparable to France has failed to form winter sea ice in the Bellingshausen Sea, alarming scientists. This unusual event, coinciding with a heatwave, raises concerns for penguins, marine ecosystems, and sea-level rise.
Conservationists propose a protected area for Ernest Shackleton's Endurance wreck in the Weddell Sea, fearing climate change and increased shipping may damage the historic site. The proposal passed a key meeting but awaits final approval from CCAMLR.
A report has warned that old chemicals found inside historic huts belonging to Ernest Shackleton and Robert Falcon Scott in Antarctica could pose potential explosive hazards. The chemicals, possibly picric acid crystals, solution, and peroxide crystals, require careful handling and disposal.
A report has warned that old chemicals found inside historic huts belonging to explorers Ernest Shackleton and Robert Falcon Scott in Antarctica could pose potential explosive hazards. The chemicals, possibly picric acid and peroxide crystals, require careful handling and disposal, with experts noting they can detonate under specific conditions like heat or shock.
Scientists express concern over the Bellingshausen Sea in West Antarctica, which is missing a 'France-sized' chunk of winter sea ice, approximately 650,000 sq km. This area, typically ice-covered in June, remains largely ice-free, raising fears it may not reform.

Australia's One Nation party faces scrutiny over 'sloppy' financial reports with over $1m in missing assets. US President Trump accuses Iran of 'playing us for suckers' amid imminent strike threats. Thousands of Australian women face medicine uncertainty, while World Cup predictions begin.
Australia's $528M icebreaker RSV Nuyina cannot refuel in its home port of Hobart due to restrictions related to the Tasman Bridge. Despite fitting under the bridge, directional stability concerns and simulations showing potential collisions have led to the rejection of refueling applications. This forces the ship to travel 674km to Burnie, adding nearly $900,000 annually to its fuel costs.
Tasmanian authorities are reviewing a ban preventing the Antarctic icebreaker RSV Nuyina from travelling under Hobart's Tasman Bridge to refuel. The detour adds significant cost and time, prompting consideration of new modelling and alternative solutions.
Tasmanian authorities are reviewing a ban preventing the Antarctic icebreaker RSV Nuyina from travelling under Hobart's Tasman Bridge. The ban, imposed due to directional stability concerns, forces a costly detour for refueling. New modeling is being considered to assess the feasibility of transit.
Japanese lawmaker Mitsuhiro Yokota voiced concerns in parliament about potential future exploitation of Antarctica's vast mineral and energy resources, specifically mentioning China's interest and its resource acquisition ambitions.
South Korea will host the 49th Antarctic Treaty Consultative Meeting (ATCM) and the 29th Committee for Environmental Protection in Incheon in May next year, marking the first time in 32 years it has hosted the event.
The federal government has rejected Tasmania's proposal to use road tankers to refuel the Antarctic icebreaker RSV Nuyina, deeming it unacceptable. The state government missed a July 31 deadline for a solution, impacting a $188 million deal.
Seven shipping containers, including one with diesel and others with rubbish, broke off from an Antarctic ice shelf during a storm and drifted on a newly formed iceberg. While some waste was salvaged, the fuel container is presumed to have leaked, posing an environmental risk.
Seven shipping containers, including one with diesel and others with rubbish, broke off from Antarctica's coast on an iceberg. German officials are assessing environmental impact, with fuel leakage a major concern.
