NASA rolls Moon rocket out to Kennedy Space Center launch pad

The Artemis-1 rocket is rolled out from the Vehicle Assembly Building en route to Launch Pad 39B at the Kennedy Space Center in Florida

NASA rolled out its largest-ever rocket to a launch pad in Florida on Friday and will try again 10 days from now to blast off on a much-delayed uncrewed mission to the Moon.

After two launch attempts were scrubbed this summer because of technical problems, the rocket returned to the Vehicle Assembly Building to protect it from Hurricane Ian.

The US space agency used the time to carry out minor repairs and to recharge the batteries that power systems on the Space Launch System (SLS) rocket.

The SLS rocket’s four-mile (six-kilometer) journey from the Vehicle Assembly Building to the Kennedy Space Center’s Launch Pad 39B took nearly nine hours, NASA said.

The 322-foot (98-meter) rocket was rolled out slowly on a giant platform known as the crawler-transporter designed to minimize vibrations.

The next launch attempt is scheduled for 12:07 am Eastern Time (0407 GMT) on November 14 with backup dates on November 16 at 1:04 am and November 19 at 1:45 am.

“We’re comfortable launching at night,” NASA associate administrator Jim Free said at a briefing on Thursday.

Free said radar and infrared camera imaging will provide the necessary data to track the rocket’s performance.

If the rocket blasts off on November 16, the mission would last a little more than 25 days with the crew capsule splashing down in the Pacific Ocean on December 9.

The highly anticipated uncrewed mission, dubbed Artemis 1, will bring the United States a step closer to returning astronauts to the Moon five decades after humans last walked on the lunar surface.

The goal of Artemis 1, named after the twin sister of Apollo, is to test the SLS rocket and Orion crew capsule that sits on top.

Mannequins equipped with sensors are standing in for astronauts on the mission and will record acceleration, vibration and radiation levels.

The Orion capsule is to orbit the Moon to see if the vessel is safe for people in the near future. At some point, Artemis aims to put a woman and a person of color on the Moon for the first time.

And since humans have already visited the Moon, Artemis has its sights set on another lofty goal: a crewed mission to Mars.

During the trip, Orion will follow an elliptical course around the Moon, coming within 60 miles (100 kilometers) at its closest approach and 40,000 miles at its farthest — the deepest into space ever by a craft designed to carry humans.

Sunak vows UK will be global leader on climate action

UK Prime Minister Rishi Sunak attended a pre-COP27 climate reception at Buckingham palace with King Charles III

Prime Minister Rishi Sunak on Friday promised Britain would build on the achievements of its presidency of the COP26 climate change summit in Glasgow, as Egypt prepared to host the next meeting to tackle global warming.

The UK hosted world leaders in Scotland last year, with nearly 200 countries coming together on a global deal to combat climate change and work towards net-zero emissions.

Sunak said at a reception at Buckingham Palace that he believed “the agreements we reached in Glasgow are a source of hope for the world” and insisted London’s “global leadership will continue”.

“It is the hope of many that the legacy of this summit, written in history books yet to be printed, will describe you as the leaders who did not pass up the opportunity, and that you answered the call of those future generations,” Sunak told guests.

King Charles III invited more than 200 world leaders, business figures and environmentalists to the palace reception. Those attending included British fashion designer Stella McCartney and US climate envoy John Kerry.

Sunak spoke after changing his mind and deciding to attend the COP27 summit, having faced a storm of criticism for saying he could not go due to his busy schedule at home. 

The summit starts in the Red Sea resort of Sharm el-Sheikh on Sunday.

Charles on the other hand has followed government advice not to go.

Sunak praised the monarch’s devotion to environmental causes, saying Charles “has been working to help find practical solutions to climate change and biodiversity loss for more than 50 years”.

Australia's 'irreplaceable' platypus threatened by dams: study

'Platypuses are arguably the most irreplaceable mammal,' the lead author of the new study says

The future of the platypus, a unique duck-billed, egg-laying mammal only found in Australia, is under threat because they cannot climb over tall river dams, according to a new study.

The platypus is an oddity in many ways. As well as its duck-like bill and egg-laying, it is a rare venomous mammal, brandishing centimetre-long poisonous spurs on its hind legs.

They are also one of the only mammals who can locate prey by detecting electric fields and whose fur glows blue-green under an ultraviolet light. Platypuses even have 10 sex chromosomes — most mammals have two.

But the number of platypuses has fallen by 50 percent since Europeans settled Australia more than two centuries ago, according to previous research.

Its habitat has increasingly come under threat from climate change-fuelled extreme weather events including drought and fire. They are also preyed upon by invasive species such as foxes, cats and dogs.

A new study published in the journal Communications Biology this week identified a new threat: platypuses are not able to climb over large, human-made dams in rivers.

The study’s lead author, Jose Luis Mijangos of the University of New South Wales, told AFP that “there might be as few as 30,000 mature platypuses” left in Australia.

More than three quarters of Australia’s dams measuring over 10 metres (33 feet) are in regions where platypuses live, the study said.

Some platypuses, which mostly live in rivers and streams but can use their webbed feet to walk on land, have been reported to be able to cross smaller dams.

But they cannot get over taller dams, isolating the animals from each other, the study found.

– Increased inbreeding –

The researchers took the DNA samples of 274 platypuses from nine rivers in the states of Victoria and New South Wales. Five of the rivers have dams between 85 to 180 metres tall, while the others flow unimpeded.

Comparing the samples, they found that genetic differences were four to 20 times higher in platypus populations around the dammed rivers compared to those not living near dams, indicating the first group rarely mixed with others.

They also estimated that the genetic differences had increased in every platypus generation since the nearby dams had been completed. 

“These results suggest that almost no or no platypuses have passed around the dams since they were built,” Mijangos said.

As a result, “populations are fragmented, which means that the ability to recolonise available habitat or migrate to areas with more suitable conditions is restricted,” he added.

“Fragmentation also simultaneously reduces both local population size and gene flow, each of which is expected to lead to increased inbreeding and reduction of the genetic variation.”

To address the problem, the researchers propose structures be built to help the platypuses scale the dams. They also suggested that humans could relocate some platypuses to promote diversity.

After all, the platypus is too weird to be lost.

“Platypuses are arguably the most irreplaceable mammal because they have a unique combination of features,” Mijangos said.

At 'African COP', continent's climate needs may go unmet

Maasai women affected by a worsening drought buy barley straw for their animals at a livestock market in Kenya

It is being billed as the “African COP” but scientists and campaigners on the continent least responsible for climate change fear the UN summit that begins on Sunday in Egypt will once again leave them sidelined.

As the toll of climate-linked disasters mounts in debt-ridden countries across Africa, governments are demanding that rich polluters pay for the harm their emissions have already caused, known as “loss and damage”.

“Historically, Africa is responsible for less than four percent of global emissions, but Africans are suffering some of the most brutal impacts of the climate crisis,” said Ugandan campaigner Vanessa Nakate.

“We need financial support to cope with the loss and the damage we’re experiencing across the continent. We need polluters to compensate for the destruction they’ve caused.” 

Richer governments rejected a call for a financial mechanism to address losses and damage at last year’s climate talks in Glasgow and instead negotiators agreed to start a “dialogue” on financial compensation.  

But as floods, heatwaves and droughts sweep across the planet, hitting the most vulnerable hardest, activists are hoping the issue will take centre stage at COP27 in Egypt.

– ‘From words to deeds’ –

In an opinion piece in The Guardian on Friday, the leaders of France, the Netherlands and Senegal urged greater — and more concrete — support for Africa, especially for adaptation. 

“For Africa, climate change is an irreversible reality. It’s too late to turn back the clock,” wrote France’s Emmanuel Macron, Mark Rutte of the Netherlands and Macky Sall, Senegal’s leader and chair of the African Union.

“COP27 is a vital opportunity for the world to support Africa in facing the impact of climate change… the conference must generate a breakthrough on finance for climate adaptation and move from words to deeds.”

In Africa alone, extreme weather events have killed at least 4,000 people and displaced 19 million so far this year, a study by the Carbon Brief news service said last week.

The ongoing drought in East Africa is impacting the livelihoods of more than nine million people, and 1.4 million people have been displaced in recent weeks in the worst floods on record in Nigeria.

The UN’s Intergovernmental Panel on Climate Change in February warned that tens of millions of Africans face a future marked by drought, disease and displacement due to global heating.

“Multiple African countries are projected to face compounding risks from: reduced food production across crops, livestock and fisheries; increasing heat-related mortality; heat-related loss of labour productivity; and flooding from sea level rise,” scientists wrote in a dedicated chapter on the continent.

Chukwumerije Okereke, a professor in environment and development at Britain’s University of Reading, said that African nations would demand greater action from the polluting countries that are driving climate change.

“African countries believe they have been significantly shortchanged because they are the most vulnerable to the impact of climate change,” he told AFP. 

“The best way to stave off a more devastating impact of climate change on the continent is through rapid decarbonisation.”

Countries agreed at last year’s UN climate talks in Glasgow to raise the ambition of their emissions-cutting plans. However, the UN says those additional measures would result in a pollution cut of less than one percent by 2030. 

The Glasgow summit also produced a new strategy for financing the energy transition, with a group of rich nations committing to providing $8.5 billion to coal-dependent South Africa over three to five years — in grants and loans — to help its climate plan and catalyse private investment.

This week the World Bank said that South Africa, one of the world’s largest greenhouse gas emitters, will require at least $500 billion to achieve carbon neutrality by 2050. 

Susan Chomba, director of the African NGO Vital Landscapes, said governments should use COP27 to push green development investment on the continent.  

“We do need development for our people and we need to use the resources that are within our reach on the continent,” she said.

“The war in Ukraine has exposed the naked risk of overdependence on fossil fuels, even for the richest economies, but also the ripple effect that it is having on energy fertiliser and food prices on the continent.” 

– ‘Fake promises’ –

Progress at recent COPs has been stymied by a failed promise by rich nations to provide at least $100 billion annually to developing ones to help decarbonise while adapting to climate impacts.

“COP27 is going to be a COP where we’re going to be able to build up trust,” said Ineza Grace from the Loss and Damage Youth Coalition. 

“All of those fake promises have never been accomplished and we are the generation that is kind of living in the hotspot. But we are also a generation that does not want to sit down and just continue to be victims.”

Okereke said to expect “constructive ambiguity” around loss and damage finance.

“If they do set up such a facility then it might still be four or five years before the structure or the functionalities of such a facility is agreed,” said Okereke. 

“So poor countries should be aware that while having a facility is a victory, it may not necessarily translate to more dollars coming to them.”

Kenya drought kills more than 200 elephants

Victims: Elephants and other big herbivores are suffering in Kenya's historic drought

More than 200 elephants and hundreds of zebras and gnus have died in Kenya’s worst drought in four decades, the country’s tourism minister said on Friday.

The crisis has affected nearly half of Kenya’s regions and at least four million out of its 50 million people.

“The drought has caused mortality of wildlife, mostly herbivore species,” Tourism Minister Peninah Malonza told a press conference in Nairobi on Friday, adding that 14 species had been identified as badly hit.

“The mortalities have arisen because of depletion of food resources as well as water shortages.”

Between February and October, officials recorded the death of 205 elephants, 512 gnus, 381 zebras, 12 giraffes and 51 buffalo, she said. 

“Elephants in (the) Amboseli and Laikipia-Samburu regions are worst affected by the drought, as the ecosystems (there) have recorded more than 70 elephant deaths,” Malonza said.

The authorities are dropping off hay for the animals, she said.

Last year the country had 36,000 elephants, according to tourism ministry estimates.

Four consecutive rainy seasons have failed in Kenya, Somalia and Ethiopia and millions across the Horn of Africa have been driven into extreme hunger. More than 1.5 million cattle have died in Kenya alone.

Dutch to shoot paintball pellets at wolf to scare it away

Wolves are protected animals in the Netherlands

Dutch authorities plan to shoot paintball pellets at a young wolf to teach it to stay away from people, after it got too close to visitors at a national park.

“Over the past few weeks, a wolf in the Hoge Veluwe national park had approached hikers and visitors,” said Gueldre province in the centre of the country on Tuesday.

“It’s probably a young animal. To prevent the wolf from being tamed and to teach the animal to keep away from people, Gueldre law enforcement officers will dissuade the wolf with paintball guns.”

The aim is to teach the animal to keep at least 30 metres (yards) from people, according to local media.

Wolves are protected animals in The Netherlands, meaning that disturbing or hunting them is only possible with special authorisation.

Gueldre authorities said they had a permit and planned to start the paintball shooting shortly.

Wolves killed some 30 sheep in the northern province of Drenthe in September, according to the BIJ12 agency that keeps track of damage caused by wolves in the country.

It estimates that there are currently four packs of wolves and 11 lone wolves in the Netherlands.

India's capital to shut schools as toxic smog chokes city

The burning of rice paddies after harvests across northern India takes place every year

Primary schools in India’s capital New Delhi will shut to protect children from the toxic smog choking the megacity of 20 million people, authorities said Friday.

Smoke from farmers burning crop stubble, vehicle exhaust and factory emissions combine every winter to blanket the capital in a deadly grey haze.

On Friday, levels of the most dangerous PM2.5 particles — so tiny they can enter the bloodstream — were almost 25 times the daily maximum recommended by the World Health Organization, according to monitoring firm IQAir.

Delhi chief minister Arvind Kejriwal, under fire from residents and political opponents for failing to address the crisis, said primary schools would be closed from Saturday until “the pollution situation improves”. 

“No child should suffer in any way,” Kejriwal told reporters.

Delhi is frequently ranked as one of the world’s most polluted cities. On Friday it again topped IQAir’s list of major cities with the worst air quality. 

A Lancet study in 2020 attributed 1.67 million deaths to air pollution in India during the previous year, including almost 17,500 in the capital.

Authorities regularly announce different plans to reduce the pollution, for example by halting construction work, but to little effect.

Tens of thousands of farmers across north India set fire to their fields at the start of every winter to clear crop stubble from recently harvested rice paddies. 

The practice is one of the key drivers of Delhi’s annual smog problem and persists despite efforts to persuade farmers to use different clearing methods.

Farm fire smoke accounted for a third of Delhi’s air pollution on Thursday, according to India’s air quality monitoring agency.

The problem is also a political flashpoint — with Delhi and the northern state of Punjab governed by the Aam Aadmi Party (AAP), a rival to Prime Minister Narendra Modi’s Bharatiya Janata Party.

But Kejriwal called for an end to “blame games and finger-pointing” over responsibility for tackling the smog, after India’s environment minister lambasted the AAP for presiding over an increase in farm fires.

“It won’t help in finding solutions. We can blame them, and they can blame us, but that would lead to nothing,” he said.

“Farmers need solutions,” he added. “The day they get a solution, they will stop burning the stubble.”

Egypt's COP27 climate summit comes at a 'watershed moment'

The COP27 climate summit follows a cascade of extreme weather events, including massive flooding in Bangladesh

Leaders of a divided world meet in Egypt on Monday tasked with taming the terrifying juggernaut of global warming as they face gale-force geopolitical crosswinds, including the war in Ukraine and economic turmoil.

Expectations are high from a world justifiably anxious about its climate-addled future as deadly floods, heat waves and storms across the planet track worst-case climate scenarios.

The November 6-18 meeting in the resort town of Sharm el-Sheikh will also be dominated by the growing need of virtually blameless poor nations for money to cope not just with future impacts, but those already claiming lives and devastating economies.

UN chief Antonio Guterres said Thursday it was time for a “historic pact” between developed and emerging countries, with richer nations providing financial and technical assistance to help poorer ones speed up their renewable energy transitions.

“If that pact doesn’t take place, we will be doomed, because we need to reduce emissions, both in the developed countries and emerging economies,” Guterres told reporters.

Last week the UN warned that “there is no credible pathway in place” for capping the rise in global temperatures under the Paris Agreement target of 1.5 degrees Celsius.

While worst-case projections are less dire than a decade ago, current policies would still see Earth’s surface warm a catastrophic 2.8C, and no less than 2.4C even if countries meet all their carbon-cutting pledges under the Paris treaty.

“There have been fraught moments before,” said E3G think tank senior analyst Alden Meyer, recalling other wars, the near collapse of the UN-led process in 2009, and Donald Trump yanking the United States out of the Paris Agreement in 2016.

“But this is a perfect storm. It has even given rise to a new term: polycrisis,” said the 30-year climate issue veteran.

Casting an even longer shadow on negotiations in Egypt than Russia’s invasion of Ukraine, many experts say, is the further erosion of Sino-US relations, which in the past have anchored breakthroughs in climate diplomacy.

– ‘Watershed moment’ –

At last year’s COP26 in Glasgow, the world’s two biggest economies conspicuously carved out a safe space for climate, issuing a joint statement.

But a Taiwan visit in August by US congressional leader Nancy Pelosi prompted Beijing to shut down bilateral climate channels. Sweeping restrictions imposed last month by the Biden administration on the sale of high-level chip technology to China deepened the rift.

“We are at a watershed moment,” said Li Shuo, a Beijing-based policy analyst with Greenpeace International.

“If the politics are so bad that the world’s two biggest emitters won’t talk to each other, we’re not going to get to 1.5C.”

US President Joe Biden and Chinese leader Xi Jinping are set to attend the G20 summit in Bali days before the talks in Egypt close. Should the two leaders meet, “that dynamic would play back to Sharm el-Sheikh”, said Li.

Biden will arrive in Egypt touting the landmark Inflation Reduction Act (IRA), which earmarks nearly $400 billion — potentially twice that amount — to speed the greening of the US economy.

But legislative elections the day after the UN climate talks open could dampen US bragging rights if Republicans hostile to international climate action take either or both houses of Congress. 

US inflation and a strong dollar, meanwhile, have heaped pain on debt-ridden poor and emerging economies.

A bright spot at COP27 will be the arrival of incoming Brazilian president Luiz Inacio Lula da Silva, who has vowed to aim for zero deforestation in the Amazon, reversing the extractive policies of Jair Bolsonaro, who will step down on January 1.

– Money matters –

COP27 will arguably boil down to a trio of interlocking priorities: emissions, accountability and money.

The make-or-break issue is likely to be the creation of a separate pool of capital for “loss and damage” — UN climate lingo for unavoidable and irreversible climate damages.

The United States and the European Union — fearful of creating an open-ended reparations framework — have dragged their feet on this issue for years and question the need for a separate financial channel. 

But patience has run thin.

“The success or failure of COP27 will be judged on the basis of whether there is agreement on a financing facility for loss and damage,” said Munir Akram, Pakistan’s UN ambassador and chair of the powerful G77+China negotiating block of more than 130 developing nations.

“Where there’s a will, there’s a way,” Akram told AFP in an interview. 

Rich nations will also be expected to set a timetable for the delivery of $100 billion per year to help developing countries green their economies and build resilience against future climate change. 

The promise is already two years past due and remains $17 billion shy, according to the OECD.

Last year’s COP26 in Glasgow prioritised reducing carbon pollution, mostly through sideline agreements orchestrated by host Britain to curb methane emissions, halt deforestation, phase out fossil fuel subsidies and ramp up the transition to renewable energy.

Nations agreed to review their carbon-cutting pledges annually and not just every five years, though only a handful of nations have done so in 2022.

Guterres, meanwhile, will unveil a critical assessment of “net-zero” commitments by companies, investors and local governments to become carbon neutral.

Arctic fires could release catastrophic amounts of C02: study

An aerial view of land charred by fire west of the Russian city of Yakutsk in Siberia in July 2021

Global warming is responsible for bigger and bigger fires in Siberia, and in the decades ahead they could release huge amounts of carbon now trapped in the soil, says a report out Thursday.

Researchers fear a threshold might soon be crossed, beyond which small changes in temperature could lead to an exponential increase in area burned in that region.

In 2019 and 2020, fires in this remote part of the world destroyed a surface area equivalent to nearly half of that which burned in the previous 40 years, said this study, which was published in the journal Science.

These recent fires themselves have spewed some 150 million tonnes of carbon into the atmosphere, the scientists estimate, contributing to global warming in what researchers call a feedback loop.

The area above the Arctic circle heats up four times faster than the rest of the planet and “it is this climate amplification which causes abnormal fire activity,” David Gaveau, one of the authors of this study, told AFP.

Researchers concentrated on an area five and a half times the size of France and with satellite pictures observed the surface area burned each year from 1982 to 2020. 

In 2020, fire charred more than 2.5 million hectares (6.2 million acres) of land and released, in CO2 equivalent, as much as that emitted by Spain in one year, the scientists concluded.

That year, summer in Siberia was on average three times hotter than it was in 1980. The Russian city of Verkhoyansk hit 38 degrees Celsius in summer, a record for the Arctic.

The average air temperature in summer, from June to August, surpassed 10 degrees Celsius only four times in the period under study: in 2001, 2018, 2019 and 2020. These turned out to be the years with the most fires too.

The team fears that this threshold at 10 degrees Celsius will be a breaking point that is surpassed more and more often, said Gaveau.

“The system goes out of whack, and for a small increase beyond 10 degrees Celsius we suddenly see lots of fires,” he said.

– Source of permafrost –

Arctic soils store huge amounts of organic carbon, much of it in peatlands. This is often frozen or marshy, but climate warming thaws and dries peatland soil, making large Arctic fires more likely.

Fire damages frozen soil called permafrost, which releases even more carbon. In some cases it has been trapped in ice for centuries or more.

“This means that carbon sinks are transformed into sources of carbon,” Gaveau said. 

“If there continue to be fires every year, the soil will be in worse and worse condition. So there will be more and more emissions from this soil, and this is what is really worrisome.”

An elevated amount of CO2 was released in 2020 but things “could be even more catastrophic than that in the future,” said Gaveau, whose company, TheTreeMap, studies deforestation and forest fires.

Higher temperatures have a variety of effects: more water vapor in the atmosphere, which causes more storms and thus more fire-sparking lightning. And vegetation grows more, providing more fuel for fire, but it also breathes more, which dries things out.

– Different scenarios –

Looking ahead to the future, the study analyzed two possible scenarios. 

In the first one, nothing is done to fight climate change and temperatures keep rising steadily. In this case fires of the same gravity as in 2020 may occur every year. 

In the second scenario, concentrations of greenhouse gases stabilize and temperatures level out by the second half of this century. In this case severe fires like those of 2020 would break out on average every 10 years, said Adria Descals Ferrando, the main author of the study.

Either way “summers with fires like those of 2020 are going to be more and more frequent starting in 2050 and beyond,” said Gaveau.
