Greenland Is Melting at Some of the Fastest Rates in 12,000 Years

The vast Greenland ice sheet is melting at some of its fastest rates in the past 12,000 years. And it could quadruple over the next 80 years if greenhouse gas emissions don’t decline dramatically in the coming decades.

Research published yesterday in the journal Nature warns that the ice sheet’s future losses depend heavily on how quickly humans cut carbon emissions today.

Led by Jason Briner of the University at Buffalo, State University of New York, the study is among the first to compare the possible future of the ice sheet with its ancient past.

“Now we’re really able to put into perspective just how anomalous our current change is and future changes might be,” said Josh Cuzzone, a co-author of the study and a scientist at the University of California, Irvine.

The researchers used models, informed by data from ancient ice samples drilled out from the ice sheet, to

TikTok Users in UK, Germany, France, Italy, Norway: Ages, Screentime, Open Rates

One in four Britons use TikTok every month, with 17 million regulars spending just over an hour a day on the app, signaling the upstart social network has built a local following almost half as large as Facebook Inc.’s in just three years. 

The data, seen by Bloomberg and contained within a presentation this summer from TikTok’s marketing solutions arm, TikTok for Business, shows that among that group four in 10 are between the ages of 18 and 24 as monthly active users, so-called MAUs. The average Brit uses the app for 66 minutes a day and opens TikTok 13 times in 24 hours. 

In comparison, marketing and research firms We Are Social and Hootsuite estimate Facebook has 37 million users in the U.K.

TikTok has grown prodigiously as more people seek entertainment during lockdowns triggered by the coronavirus. A similar presentation distributed in

New data on US infection rates helps identify COVID-19 turning points — ScienceDaily

Mathematicians have developed a framework to determine when regions enter and exit COVID-19 infection surge periods, providing a useful tool for public health policymakers to help manage the coronavirus pandemic.

The first published paper on second-surge COVID-19 infections from US states suggests that policymakers should look for demonstrable turning points in data rather than stable or insufficiently declining infection rates before lifting restrictions.

Mathematicians Nick James and Max Menzies have published what they believe is the first analysis of COVID-19 infection rates in US states to identify turning points in data that indicate when surges have started or ended.

The new study by the Australian mathematicians is published today in the journal Chaos, published by the American Institute of Physics.

“In some of the worst performing states, it seems that policymakers have looked for plateauing or slightly declining infection rates. Instead, health officials should look for identifiable local maxima

It’s Mostly About Rates for Growth-Deprived Emerging Markets

(Bloomberg) — Record low interest rates, rising commodity prices and improved mobility data have been buoying expectations of a recovery across emerging markets even as investors cast a wary eye toward November’s U.S. presidential election.

Yet for all those plus points — and any small boost provided by a gentler geopolitical backdrop — it’s rate differentials that are sustaining much of the investor demand. Bond funds last week extended their longest streak of inflows since a 12-week run in the fourth quarter of 2017, according to EPFR Global, with China bond funds attracting “above-average” interest. Bond inflows into ETFs focused on the developing-world also offset withdrawals from stocks last week.

“Even though policy rates in emerging markets have come down a lot, many of them show meaningful relative interest-rate advantages versus the dollar now, despite benign inflation,” said Morgan Harting, a New York-based money manager at AllianceBernstein who oversees about
