    Denmark Eyes Green
    Domestic Flights by 2030
    --Renewables Now
    January 7, 2022
    The Danish government has pledged to stop the use of fossil fuels for domestic flights and make all flights across the country fossil fuel free by the end of the decade.
    The ambitious plan was announced by Prime Minister Mette Frederiksen in her New Year’s address in support of the country’s national climate targets. According to it, the first domestic flights run on green fuel will be made in 2025 at the latest.
    “To travel is to live and therefore we fly. But at the same time, it damages our climate. We want to make flying green,” Frederiksen said. She noted, however, that achieving such a goal would be a challenge but pointed out that researchers and companies are already working to find solutions. If these come to be successful, Denmark’s endeavour would be a breakthrough for the whole world, she added.
    Denmark is aiming for a 70% cut in overall carbon emissions by 2030, compared to 1990 levels and is adopting a range of policies in support of the goal. Among them is its commitment to cease all offshore oil and gas pumping activities by 2050.
    Energy-related Carbon
    Emissions Fell in 2020
    -Reneable Energy World

    Carbon dioxide emissions in 2020 were the lowest in nearly 40 years, according to a 2021 year-end report by the U.S. Energy Information Administration (EIA).
    U.S. energy-related CO2 emissions totaled 4.6 billion metric tons, down 11% from 2019. That represented the nation’s lowest total since 1983. EIA cited lower energy demand due to the COVID-19 pandemic, as well as continuing changes in the electricity generation fuel mix.
    The EIA said commercial sector emissions totaled 732 million metric tons, a 12% decrease from 2019. Industrial emissions dropped to 1.3 billion metric tons, an 8% difference.
    Residential sector emissions fell 6% to 894 million metric tons in 2020, the report said. Although people stayed home more often in 2020, a warmer-than-average winter led to a lower demand for heat. That, in turn, resulted in the overall emissions decrease.
    According to the EIA report, emissions fell 15% within the transportation sector in 2020. That was the largest decline among all industries, as fewer people took cars or planes and more worked from home during the pandemic.
    Emissions from gasoline fell 13%, jet fuel emissions fell 38% and those from diesel fell 8%. Among the hardest-hit sectors during the pandemic, transportation accounted for 58% of all decreases in U.S. energy consumption.
    Dams Burst in N.E. Brazil
    As Region is Hit by Floods
    -Reuters
    December 26, 2021
    Two dams gave way in the northeastern Brazilian state of Bahia after weeks of heavy rains, swamping already swollen local rivers as flooding hit towns across the region, authorities said on Sunday.
    The Igua dam, on the Verruga river near the city of Vitoria da Conquista in southern Bahia, collapsed on Saturday night, forcing authorities to evacuate residents, mainly in the town of Itambe.
    A second dam gave way to rising water levels in Jussiape, 100 kilometers to the north, on Sunday morning, bringing more alerts for residents to move to safer ground.
    There were no reports of deaths or injuries caused by the dam failures, though bridges and roads were damaged.
    Further towards the coast in Itabuna, a city of 200,000 inhabitants, fire brigade teams rescued residents trapped in their homes in the downtown area that was under water, Reuters reporters said.
    "It's crazy by the bridge, there are waves almost 2 meters high," shopkeeper Luiz Constancia told Reuters.
    Rescuers rowed dinghies along flooded streets to reach trapped families or take them supplies. One man paddled on an inflatable mattress to reach a home.
    Residents said the level of the Cachoeira river that runs through the town located 30 kms from the coastal port city of Ilheus was the highest in 50 years.
    Dramatic Change In Store
    For the Thwaites Glacier
    -BBC News
     
    December 13, 2021
    Scientists are warning of dramatic changes at one of the biggest glaciers in Antarctica, potentially within the next five to 10 years.
    They say a floating section at the front of Thwaites Glacier that until now has been relatively stable could "shatter like a car windscreen".
    US and UK researchers are currently engaged in an intense study programme at Thwaites because of its melt rate.
    Already it is dumping 50 billion tonnes of ice into the ocean each year.
    This is having limited impact on global sea-levels today, but there is sufficient ice held upstream in the glacier's drainage basin to raise the height of the oceans by 65cm - were it all to melt.
    Such a "doomsday" scenario is unlikely to come about for many centuries, but the study team says Thwaites is now responding to a warming world in really quite rapid ways.
    "This will accelerate the pace (of Thwaites) and widen, effectively, the dangerous part of the glacier," he told BBC News.
    Thwaites is a colossus. It's roughly the size of Great Britain, or Florida, and its outflow speed has doubled in the past 30 years.
    The ITGC has established how this is happening. It is the result of warm ocean water getting under - and melting - Thwaites's floating front, or ice shelf as it's known.
