Pofatu: A new database for geochemical ‘fingerprints’ of artefacts

(Max Planck Institute for the Science of Human History) Due to the improvement and increased use of geochemical fingerprinting techniques during the last 25 years, the archaeological compositional data of stone tools has grown exponentially. The Pofatu Database is a large-scale collaborative project that enables curation and data sharing. The database also provides instrumental details, analytical procedures and reference standards used for calibration purposes or quality control. Thus, Pofatu ensures reproducibility and comparability between provenance studies.

Sea level could rise by more than 1 meter by 2100 if emission targets are not met

(Nanyang Technological University) An international study led by Nanyang Technological University, Singapore (NTU Singapore) scientists found that the global mean sea-level rise could exceed 1 meter by 2100 and 5 meters by 2300 if global targets on emissions are not achieved.

Scientists have created new nanocomposite from gold and titanium oxide

(ITMO University) ITMO University researchers together with their colleagues from France and the USA have demonstrated how a femtosecond laser can be used to tune the structure and nanocomposite properties for titanium dioxide films filled with gold nanoparticles.

USA Today Keeps Changing Date For Climate Armageddon

Environmentalists in the media often seem to want to move the goalposts on their climate Armageddon predictions. USA Today ran a story headlined “Unsuitable for ‘human life to flourish’: Up to 3B will live in extreme heat by 2070, study…

Unsuitable for ‘human life to flourish’: Up to 3B will live in extreme heat by 2070, study warns – USA TODAY

By 2070, up to 3 billion people are likely to live in climate conditions ‘deemed unsuitable for human life to flourish.’ Rapid reductions in greenhouse gas emissions could halve the number of people exposed to such hot conditions. The study…

Will an ‘unprecedented decline’ in carbon emissions help limit climate change? – USA TODAY

Worldwide emissions of carbon dioxide are forecast to drop about 8% in 2020. An energy expert calls it “a historic shock to the entire energy world.” Coal use has been especially hard hit during the lockdowns, as has natural gas…

Catastrophic outburst floods carved Greenland’s ‘Grand Canyon’

(Geological Society of America) Buried a mile beneath Greenland’s thick ice sheet is a network of canyons so deep and long that the largest of these has been called Greenland’s ‘Grand Canyon.’ This megacanyon’s shape suggests it was carved by running water prior to widespread glaciation, but exactly when and how the island’s grandest canyon formed are topics of intense debate.
