Climate activist Greta Thunberg arrived in Portugal on Tuesday after a three-week voyage across the Atlantic Ocean, telling cheering supporters that the journey had “energized” her for the fight against climate change.
The Swedish teen, whose one-woman protests outside the Swedish parliament helped inspire a global youth movement, sailed into the port of Lisbon after making a last-minute dash back from the United States to attend this year’s U.N. climate conference.
Thunberg has been steadfast in her refusal to fly because of the amount of greenhouse gases emitted by planes, a stance that put her planned appearance at the meeting in doubt when the venue was moved from Chile to Spain a month ago.
“We’ve all been on quite an adventure,” Thunberg told reporters shortly after stepping off the catamaran La Vagabonde, on which she’d hitched a ride back home to Europe. “It feels good to be back.”
Thunberg’s appearances at past climate meetings have won her plaudits from some leaders – and criticism from others who’ve taken offense at the angry tone of her speeches.
“I think people are underestimating the force of angry kids,'” Thunberg said. “If they want us to stop being angry, then maybe they should stop making us angry.”
The 16-year-old said she planned to spend several days in the Portuguese capital before heading to Madrid, where delegates from nearly 200 countries are discussing how to tackle global warming.
“We will continue the fight there to make sure that within those walls the voices of the people are being heard,” she said.
The white 48-foot (15-meter) yacht carrying Thunberg, her father Svante, an Australian family and professional sailor Nikki Henderson sailed into Lisbon amid blue skies, with a small flotilla of boats escorting it to harbor.
Her trip contrasted with the many air miles flown by most of the U.N. meeting’s 25,000 attendees.
Thunberg wanted a low-carbon form of transport to get to the climate meeting, which was switched at short notice to Spain from Chile due to unrest there.
The yacht leaves little or no carbon footprint when its sails are up, using solar panels and hydro-generators for electricity.
“I am not traveling like this because I want everyone to do so,” said Thunberg. “I’m doing this to sort of send the message that it is impossible to live sustainable today, and that needs to change. It needs to become much easier.”
She said bringing her critical message to political leaders can feel awkward. “I feel strange when I get applauded by people in power … because it’s obvious that it’s them I’m criticizing but they can’t show that in front of the cameras,” she said. “It’s quite funny sometimes.”
Looking ahead to next year’s presidential election in the United States, Thunberg said: “I just hope that someone wins that can think on the long term, not just the short term.”
Chile’s Environment Minister Carolina Schmidt, saluted Thunberg’s role speaking out about the threat of climate change.
“She has been a leader that has been able to move and open hearts for many young people and many people all over the world,” Schmidt told The Associated Press at the summit in Madrid.
“We need that tremendous force in order to increase climate action,” she said.
Near to the conference, some 20 activists cut off traffic in central Madrid and staged a brief theatrical performance to protest climate change.
Members of the international group called Extinction Rebellion held up a banner in Russian that read: “Climate Crisis. To speak the truth. To take action immediately.”
Some activists jumped into a nearby fountain while others threw them life jackets. They chanted: “What Do We Want? Climate Justice.”
Others dressed in red robes with their faces whitened to symbolize the human species’ peril danced briefly before police moved in to end the protest.
Meanwhile, the U.N. weather agency released a new report showing that the current decade is likely to set a new 10-year temperature record, providing mounting evidence that the world is getting ever hotter.
Preliminary temperature measurements show the years from 2015 to 2019 and from 2010 to 2019 “are, respectively, almost certain to be the warmest five-year period and decade on record,” the World Meteorological Organization said.
“Since the 1980s, each successive decade has been warmer than the last,” the agency said.
While full-year figures aren’t released until next March, 2019 is also expected to be the second or third warmest year since measurements began, with 2016 still holding the all-time temperature record, it said.
This year was hotter than average in most parts of the world, including the Arctic. “In contrast a large area of North America has been colder than the recent average,” the U.N. said.
The World Meteorological Organization’s annual report, which brings together data from numerous national weather agencies and research organizations, also highlighted the impacts of climate change including declining sea ice and rising sea levels, which reached their highest level this year since high-precision measurements began in 1993.

Canadian researchers have discovered an overlooked gene that plays a major role in the development of antibodies, which help the immune system recognize and fight viruses including SARS-CoV-2, bacteria and other causes of infectious disease. The gene -- FAM72A -- facilitates production of high-quality antibodies by enabling the effect of an enzyme called AID (for Activation-Induced Deaminase), the researchers showed.
Immunologists have known for two decades that AID is essential to produce antibodies capable of clearing infections, but the full mechanism of its effect has remained unknown. "Our findings answer the long-standing question of how AID does its work," said Alberto Martin, a professor of immunology at the University of Toronto's Temerty Faculty of Medicine. "FAM72A helps AID to promote mutations in antibody genes that are essential for the development of effective antibodies," he added.

Genetic mutations that lead to lasting changes in DNA occur through a process called mutagenesis. In the context of antibody development, mutagenesis unfolds largely through the AID-driven mechanisms called somatic hypermutation and class switch recombination -- both of which help antibodies gain the diversity and potency they need to counter a wide range of pathogens.
The results published in the journal Nature will help researchers better understand antibody development broadly, but they also have implications for cancer. Uncontrolled mutagenesis in B cells that produce antibodies is linked to B cell lymphoma, and FAM72A is present at very high levels in other cancers such as gastrointestinal, breast, lung, liver and ovarian cancers.
"Our data show that high levels of FAM72A promote mutations in antibody genes, so increased levels of FAM72A could spur cancer development, progression or drug resistance by increasing mutagenesis,a Martin said. Martin's team is now exploring those possibilities. Intriguingly, unlike other mammals, humans have four gene versions of FAM72A and their roles in cancer and antibody production are still unknown.

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.
This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.

This 50 MW solar power project will reduce CO2 emission by 91,020 tonnes per annum and carbon offsets of around 24,824 tonnes per annum, claimed the MCL. MCL is the leading production subsidiary of Coal India, having mining operations in Angul, Jharsuguda and Sundargarh districts of Odisha. Having achieved the highest ever capital expenditure of Rs 2,419 crore in the financial year 2020-21, the company has coal production and dispatch targets of 163 million tonnes and 182 million tonnes, respectively.
MCL was the coal mining company to introduce environment-friendly surface miner technology, which contributes over 95 per cent in coal production. As another environment-friendly initiative, the company has successfully introduced vertical rippers for blast-less over-burden removal in Hingula and Kaniha opencast projects. (IANS/ MBI)

As the nation celebrated the 114th birth anniversary of his father - renowned poet Harivansh Rai Bachchan - megastar Amitabh Bachchan remembered his dad as he penned a heartfelt note for him. The actor took to his blog where he poured his heart out and also shared an unseen photo with his father. The image in question is from Big B's wedding in 1973, where the two are caught in a sweet moment as they look at each other.
Amitabh Bachchan wrote on his blog,
"My Father , my all .. November 27th his birth in the year 1907 .. Which makes it his 114th Anniversary .. He is in the heavens, with my Mother and they celebrate .. as do we , in thought word and deed .. (sic). But first."
He then posted the picture followed by elaborate paragraphs. The megastar wrote,
"Those rare moments when one would find himself rushing against the winds to prevent the distance between us and to close it down as soon as it can be. The day of my wedding and his expression of fulfilment to not just be in congratulation but instead to be in the face of a belief, a chime, an ultimate season of love and great passion, of the quarries of the fears and conditionings of these deprived gym routines kart ..(sic)". "This could have been unknown for long facilitating years, to give not expected versions and lastly large scale informations of the insides ; but as time passed by, as does now , they explained purposely, the values of education and similarity .. Be in peace and love .. (sic)",
the veteran actor concluded his note. (IANS/ MBI)
