Climate change: Area of forests the size of France has regrown worldwide since 2000 | Climate News

Published

on

An area of forests larger than France has regrown around the world since 2000, new data suggests.

A mapping study undertaken by the Trillion Trees project found that almost 59 million hectares of forests have grown back worldwide since the turn of the millennium.

The regrown forest area could store almost 5.9 billion tonnes of carbon dioxide, which is more than the annual emissions of the US.

But environmentalists warn “vastly” more hectares of trees are being burned and cut down each year.

The study is a joint venture between WWF, BirdLife International and Wildlife Conservation Society, which looks at areas around the world where woodlands are regenerating.

They range from active restoration, where native trees and shrubs are planted, assisted natural regeneration, where the forest is encouraged to regrow by measures such as clearing invasive species or fencing land to prevent grazing and “spontaneous natural regeneration” where trees come back of their own accord.

The study highlights areas such as the Atlantic Forest in Brazil, where 4.2 million hectares have regrown since 2000, through planned efforts to restore the forest, more responsible industry practices and human migration to cities.

In Mongolia’s northern boreal forests, the study suggests 1.2 million hectares of forest have regenerated in the last 20 years, in part down to work undertaken by WWF and the Mongolian government’s increased emphasis on protected areas.

One of the reasons for the forest regrowth is because people are migrating to cities.

Central Africa and the boreal forests of Canada are also regeneration hotspots, according to the study, which examined more than 30 years of satellite data.

The survey comes after a report from WWF earlier this year which highlighted that forests almost twice the size of the UK was destroyed in global hotspots around the world between 2004 and 2017.

William Baldwin-Cantello, director of nature-based solutions at WWF, said that to avoid dangerous climate change and reverse the loss in nature, there is a need to halt deforestation and restore natural forests.

“We’ve known for a long time that natural forest regeneration is often cheaper, richer in carbon and better for biodiversity than actively planted forests.

“This research tells us where and why regeneration is happening, and how we can recreate those conditions elsewhere,” Mr Baldwin-Cantello said.

“But we can’t take this regeneration for granted – deforestation still claims millions of hectares every year, vastly more than is regenerated.

“To realise the potential of forests as a climate solution, we need support for regeneration in climate delivery plans and must tackle the drivers of deforestation, which in the UK means strong domestic laws to prevent our food causing deforestation overseas.”

Public praised for ‘heroic’ acts in detaining attacker in NZ supermarket stabbing | World News

Published

on

Shoppers and staff at a New Zealand supermarket have been praised for their courage in trying to stop an attacker armed with a knife while waiting for police to arrive.

The man stabbed four people, including two employees at the Countdown supermarket in the South Island city of Dunedin on Monday.

All four victims are in hospital, with three in a serious but stable condition, while the fourth is described as being in a moderate condition.

According to NZ media reports, one is a Department of Corrections officer, one is his wife (a nurse), the third is a manager at the supermarket and the other is a female employee.

New Zealand Police superintendent Paul Basham said he had watched CCTV footage of the attack and the efforts of bystanders to detain the man until police arrived were “nothing short of heroic”.

“This was a fast-moving and extremely traumatic event for every person in the supermarket – for the victims who were stabbed, for those who were present who tried to intervene and those who had to flee to a place of safety.

“What I can say is that those who intervened, some of whom became injured themselves, I think have acted selflessly and with great courage to prevent this man from hurting anybody else,” he said.

A man, 42, has been charged with four counts of attempted murder and he will appear in court later today.

He was also injured in the attack and was treated under police guard.

The motivation for the attack has not been confirmed, with Mr Basham saying: “On the face of what we currently know, we believe this was a random attack”.

New Zealand Prime Minister Jacinda Ardern also praised the actions of those in the supermarket during the attack, describing them as “courageous acts…to protect those around them”.

Supermarket chain Countdown said employees were “shocked and devastated” by what had happened, adding: “We are deeply upset that customers who tried to help our team members were also injured”.

The company said its priority is the injured employees and “caring for our wider team in the wake of this extremely traumatic event”.

COVID-19: Overweight and obese more likely to test positive for the virus | World News

Published

on

People with a higher body mass index – BMI – are more likely to test positive for the virus that causes COVID-19, a study suggests.

Research by Chaim Sheba Medical Centre in Israel found that people who are overweight – with a BMI between 25 and 29.9 – are 22% more likely to contract the virus.

The figure for people who are obese – with a BMI between 30 and 34.9 – rises to 27%.

For those who are morbidly obese, with a BMI at or above 40, the risk increases by 86%.

Some 26,030 people were tested between 16 March and 31 December last year and 1,178 positive COVID-19 tests were recorded.

Even after age, sex, and other medical conditions were considered, the relationship between BMI and the probability of a person testing positive remained significant, the researchers found.

The study authors concluded: “As BMI rises above normal, the likelihood of a positive SARS-CoV-2 test result increases, even when adjusted for a number of patient variables.

“Furthermore, some of the comorbidities associated with obesity appear to either be associated with an increased risk of infection or to be protective.”

People with diabetes were 30% more likely to test positive, while the likelihood was six times greater for those with high blood pressure.

But the risk was reduced for those with a history of stroke (by 39%), ischemic heart disease (by 55%) and chronic kidney disease (by 45%).

The researchers were unable to explain this.

Also, research by the IRCCS Policlinico San Donato research hospital in Italy, has found that abdominal obesity is more important than general obesity in predicting the severity of chest X-ray results in coronavirus patients.

Abdominal obesity is fat around the waist as opposed to general obesity, which is determined by BMI.

Chest X-ray severity scores were calculated by dividing each lung into three zones, with each one scoring a maximum of three points – zero for normal lung performance and three for poor function.

Some 59% of patients with abdominal obesity had a high score, whereas this was true for just 35% of those without abdominal obesity.
