Cloquet city officials will no longer require masks to be worn while inside public spaces as of Friday, May 14, due to a recent order from Minnesota Gov. Tim Walz.
Under an emergency city ordinance, Cloquet has been requiring masks to be worn while indoors in public spaces since last summer, passing the mandate in a 5-2 vote, just one day before Gov. Tim Walz announced a statewide mask mandate July 22.
While the city ordinance requiring masks to be worn by the public has not been officially repealed, City Administrator Tim Peterson explained that is deemed null and void under the recent orders from the governor surrounding mask mandates.
Lead author Dr Tim Peterson, from Monash University, said the reason for the reduced water flows was not clear. It was not linked to land use or an increase in ground water, and did not change in response to the wetness of the catchment.
“The groundwater data says it’s not going to groundwater,” he said. “It’s got to go somewhere. The only place that we found was reasonable was increased evapotranspiration per millimetre of rainfall.”
That means that 100mm of rain in 1990 would have resulted in more water flowing into rivers than 100mm falling in the same spot in 2017. In other words, that drought could result in a permanent reduction to the water supply.
Victorian rivers aren’t recovering from drought

One-third of Victorian water catchments have not recovered eight years after severe drought, according to a new paper published in
Science, and the rivers may not recover anytime soon.
The Australian Millennium Drought between 2001 and 2009 devastated communities that relied on the Murray-Darling Basin. It is commonly thought that rivers and underground water will eventually replenish following severe droughts like this.
Now, a team of researchers, led by Tim Peterson of Monash University, challenge this idea. They found that groundwater supplies had not recovered from the Millennium Drought by mid-2017, and around 80% of those catchments show no evidence they will recover in the near future.

Boom time for digital media businesses
After the media companies’ businesses bounced back in the fourth quarter of 2020, some industry executives wondered whether the rebound would carry on into 2021 or whether there would be a slump in the first quarter. Based on the latest quarterly earnings reports released by major publicly traded publishers, tech platforms and TV network owners, both circumstances seem to be true and signal a continued return to business as usual for better or worse, depending on the state of a company’s digital business.

Challenging the assumption that watershed streamflow always recovers from drought, a new study done seven years after the Millennium Drought, the worst drought ever recorded in southeastern Australia, reports that more than a third of the region s affected watersheds had not yet recovered. Of these watersheds that were still dry seven years later, most showed no evidence of recovering soon, despite the rains return. The new study s findings suggest that hydrological droughts can persist indefinitely after meteorological droughts, highlighting an amplification of climate change impacts that could present additional challenges to the sustainable use of already-threatened water resources. Watersheds are widely assumed to fully recover from droughts when precipitation resumes. However, the understanding of how watersheds recover from severe droughts is limited and often overlooked. Using the Australian Millennium Drought (2001-2009) as a natural experiment to better understa
