Amazon near tipping point of switching from rainforest to savannah – study

Climate crisis and logging is leading to shift from canopy rainforest to open grassland

Much of the Amazon could be on the verge of losing its distinct nature and switching from a closed canopy rainforest to an open savannah with far fewer trees as a result of the climate crisis, researchers have warned.

Rainforests are highly sensitive to changes in rainfall and moisture levels, and fires and prolonged droughts can result in areas losing trees and shifting to a savannah-like mix of woodland and grassland. In the Amazon, such changes were known to be possible but thought to be many decades away.

What does the first climate question at a US debate in 20 years reveal?

The question framed the existence of a human-made climate crisis as something that is for some Americans still debatable

The long-awaited climate question in last night’s presidential debate broke a 20-year silent streak from moderators on the crisis – thrusting it into prime time but also revealing just how stuck in the past much of the US is on the issue.

After more than an hour of chaos as the candidates talked over each other, the Fox News anchor Chris Wallace asked Donald Trump: “What do you believe about the science of climate change and what will you do in the next four years to confront it?”

Greenland’s ice melting faster than at any time in past 12,000 years

Increased loss of ice could trigger sea level rise of up to 10cm by end of century

Greenland’s ice is starting to melt faster than at any time in the past 12,000 years, research has shown, which will raise sea levels and could have a marked impact on ocean currents.

New measurements show the rate of melting matches any in the geological record for the Holocene period – defined as the period since the last ice age – and is likely to accelerate, according to a paper published in the journal Nature.

40% of world’s plant species at risk of extinction

Race against time to save plants and fungi that underpin life on Earth, global data shows

Two in five of the world’s plant species are at risk of extinction as a result of the destruction of the natural world, according to an international report.

Plants and fungi underpin life on Earth, but the scientists said they were now in a race against time to find and identify species before they were lost.

California braces for dangerous heat as wildfire battle continues

Triple-digit temperatures could spark new fires just a few weeks after a record heatwave

California is bracing for another dangerously warm weekend, with dry winds, parched vegetation, and triple-digit temperatures threatening to ignite new fires and complicating containment efforts in an embattled state.

With only a few weeks’ reprieve after a record heatwave in early September, firefighters have made progress in containing the dozens of blazes tearing across the region. But fatigued crews – many of whom have spent weeks fighting on the frontline – are preparing for a potentially rough week ahead.

Young people resume global climate strikes calling for urgent action

Greta Thunberg leads protests as Covid rules restrict numbers compared with last year

School pupils, youth activists and communities around the world have turned out for a day of climate strikes, intended to underscore the urgency of the climate crisis even in the midst of the coronavirus pandemic.

Social distancing and other Covid-19 control measures dampened the protests, but thousands of activists posted on social media and took to the streets to protest against the lack of climate action from world leaders. Strikes were scheduled in at least 3,500 locations around the globe.

New all-time coldest northern hemisphere temperature discovered

Reading of -69.C in 1991 from Greenland is nearly 2C colder than previous known records

The coldest temperature ever recorded in the northern hemisphere just got colder, thanks to the work of climate detectives at the World Meteorological Organization.

Searching through the WMO archives of heat records from weather stations at the top of the world, researchers found the coldest temperature reading came from an automatic weather station in Greenland in midwinter almost 30 years ago, nearly 2C (3.6F) colder than the previous known records.

A third of my country was just underwater. The world must act on climate | Sheikh Hasina

The climate crisis and Covid-19 are crying out for international cooperation, writes the prime minister of Bangladesh

One-third of my country was underwater last month. The heaviest rains in almost a decade began and have still not abated. More than 1.5 million Bangladeshis are displaced; tens of thousands of hectares of paddy fields have been washed away. Millions of my compatriots will need food aid this year.

Calamities, alas, never strike alone. The floods, which come in the wake of widespread destruction caused by Cyclone Amphan in May, are making it more difficult to contain the coronavirus. More than 2.4 million people had already been moved from the destructive path of the storm without delivering them into the even greater danger of Covid-19. Yet while the infection and death rates have been contained, concerns remain until a foolproof safeguard is acquired. Economic lockdowns have hit our textile industry and exports and forced hundreds of thousands of our international migrant workers to return home, with the vast majority remaining unemployed.

Facebook suspends environmental groups despite vow to fight misinformation

Facebook blames mistake in system for restrictions on groups including Greenpeace USA

Facebook has suspended the accounts of several environmental organizations less than a week after launching an initiative it said would counter a tide of misinformation over climate science on the platform.

Groups such as Greenpeace USA, Climate Hawks Vote and Rainforest Action Network were among those blocked from posting or sending messages on Facebook over the weekend. Activists say hundreds of other individual accounts linked to indigenous, climate and social justice groups were also suspended for an alleged “intellectual property rights violation”.

Meet the doomers: why some young US voters have given up hope on climate

Politically active young people are often championed as the Earth’s great hope to reverse the climate crisis – but many believe we’ve already passed the tipping point

When Siddharth Namachivayam casts a ballot in Colorado this fall, he’ll forego Democratic nominee Joe Biden, whom he sees as just a “Band-Aid,” and instead support the longshot Green party candidate focused on climate action.

“I guess, yeah, it’d be marginally better if Biden was president, but I don’t think Biden being president is more important than the Green party growing in the next couple of years,” Namachivayam says.

I lived the climate crisis every day of my childhood. This November, I’ll vote on it | Jessica Díaz Vázquez

Chemical headaches, plant sirens – these were the constant background to my home and school life. My community is on the climate frontline

My teacher first taught me about global warming in the third grade. She explained how an increase in greenhouse gases increased the amount of heat that could be trapped in our atmosphere. We discussed how climate change is melting the ice caps polar bears call home, leading to their extinction. We didn’t discuss how the climate crisis was already at our homes.

I grew up with the smell of freshly made salsa from chiles picked from our backyard garden, the bright colors of fruit gifted to us by neighbors, and the sound of off-key singing to Joan Sebastian and Selena Quintanilla. At school, my friends and I slipped between English and Spanish, moving between the topics of our English essay to la quinceañera de nuestra mejor amiga with ease. But looming over my vibrant community was, and is, the fossil fuel industry.

World’s richest 1% cause double CO2 emissions of poorest 50%, says Oxfam

Charity says world’s fast-shrinking carbon budget should be used to improve lot of poorest

The wealthiest 1% of the world’s population were responsible for the emission of more than twice as much carbon dioxide as the poorer half of the world from 1990 to 2015, according to new research.

Carbon dioxide emissions rose by 60% over the 25-year period, but the increase in emissions from the richest 1% was three times greater than the increase in emissions from the poorest half.

My country may be swept away by the climate crisis if the rest of the world fails to uphold its promises | President David Kabua

Now is a time for courage. It will take sacrifices from everyone for us all to survive, the president of the Marshall Islands writes

My country joined the United Nations nearly 30 years ago, in September 1991. But unless my fellow member states take action, we may also be forced from it: the first country to see our land swept away by climate change.

As the UN general assembly meets in New York, celebrating the 75th anniversary of its formation, we must ask: how many of the 193 nations that it brings together will survive to reach its centenary?

World fails to meet a single target to stop destruction of nature – UN report

‘Humanity at a crossroads’ after a decade in which all of the 2010 Aichi goals to protect wildlife and ecosystems have been missed

The world has failed to meet a single target to stem the destruction of wildlife and life-sustaining ecosystems in the last decade, according to a devastating new report from the UN on the state of nature.

From tackling pollution to protecting coral reefs, the international community did not fully achieve any of the 20 Aichi biodiversity targets agreed in Japan in 2010 to slow the loss of the natural world. It is the second consecutive decade that governments have failed to meet targets.

Biden condemns Trump as ‘climate arsonist’ as wildfires burn – live

Trump has landed in California, where he will receive a briefing on the west coast wildfires, which have already claimed at least 35 lives.

“There has to be good, strong forest management, which I’ve been talking about for three years with the states, so hopefully they’ll start doing that,” Trump said.
