Data from the blaze in Utah could improve models of how wildfire smoke spreads.

'Trees are the lifeblood of our nation, and it is more important than ever to ensure they are rooted not only in our countryside, but in our towns and cities too'

What's low-tech, sustainable and possibly the most effective thing we can do to fight climate change? Planting trees. A trillion of them.

One of the main nurseries for an Ontario tree planting program that's being scrapped by the province said it will likely have to destroy about three million trees because of the cancellation.

Arborist David Milarch is on what he calls a spiritual quest to save California’s coastal redwoods, the largest, strongest, oldest, trees on earth. He believes the fast-growing giants are the best tool we have for fighting climate change. Growing at a rate of 10 feet per year, redwoods are among the fastest growing species of trees on Earth. An average redwood weighs 1000 tons, meaning it is capable of pulling a lot of carbon from the atmosphere, Milarch says in the video below:

Alipay has had millions of trees planted across China as part of a green initiative, it was announced on Earth Day. The ‘Ant Forest’ program within the Alipay app rewards users for making environmentally friendly decisions in their daily lives through a points system which can then be used to plant trees. At present, trees are being planted in areas of China with low vegetation, with the company saying it has planted 100mn trees so far. Ant Forest was first launched in 2016.

There is no doubt that the mass destruction of trees — deforestation — is increasing day by day and also this process is sacrificing the long-term advantages of live trees only for short-term profit. As per reports from National Geographic, forests may still cover about 30 percent of the world’s land but, they are vanishing at an alarming rate. Also, another report by World Bank states that between 1990 and 2016, the world lost around 502,000 square miles ( 1.3 million square kilometers) of the forest area that is larger than South Africa’s area (1.22 million square kilometers).

Scientists are optimistic that innovative techniques can pinpoint the true origin of timber.

Plans to triple the area of plantations will not meet 1.5 °C climate goals. New natural forests can, argue Simon L. Lewis, Charlotte E. Wheeler and colleagues.

Everyone knows plants need CO2 to grow. But does more CO2 make plants grow more and capture more CO2, mitigating climate change? Not likely, say a growing number of studies — most recently one that looked at centuries-old Canadian trees.

Insects like the cold-hardy emerald ash borer could see mass die-offs, but survivors could have hardier offspring

A tree made famous by the TV fantasy drama Game of Thrones has fallen in strong winds. Gale force winds of up to 60 mph hit Northern Ireland overnight on Saturday. The Dark Hedges are a tunnel of beech trees on the Bregagh Road near Armoy that have become an an international tourist attraction since featuring in the hit series.

Saplings from clones of the world's largest and longest-lived trees, felled for timber more than a century ago, could be key to fighting climate change.

The federal judges noted "the Forest Service's serious environmental concerns that were suddenly, and mysteriously, assuaged in time to meet a private pipeline company's deadlines."

Researchers conducting a 5-year-long study examining snow cover in a northern hardwood forest region found that projected changes in climate could lead to a 95 percent reduction of deep-insulating snowpack in forest areas across the northeastern United States by the end of the 21st century. The loss of snowpack would likely result in a steep reduction of forests' ability to store climate-changing carbon dioxide and filter pollutants from the air and water.

Over 300 days during World War One, these villages were completely wiped out – along with hundreds of thousands of French and German soldiers – during the Battle of Verdun.
