The latest garbage science from the BBC:
Climate change threatens the health and survival of urban trees, with more than half of species already feeling the heat, according to a new study.
Oaks, maples, poplars, elms, pines and chestnuts living in the city are among more than 1,000 tree species marked at risk from climate change.
The scientists wanted to better protect existing trees and introduce drought-resistant varieties.
Trees have a cooling effect and provide shade, making cities more livable.
Manuel Esperon-Rodriguez of Western Sydney University in Penrith, Australia, says many trees in urban areas are already under stress from climate change, and as it gets warmer and drier, the number of species at risk potential will increase.
Trees on streets and cities can improve physical and mental health, are important for social inclusion, and can mitigate the impact of rising temperatures – something that has affected families in recent years. pandemic, he said.
He told BBC News: “All of these benefits are mainly provided by large mature trees, so we need to make sure that what we are planting today will reach that stage, where they can provide all those benefits for future generations.
The researchers used the Global Urban Tree Inventory – a database that records more than 4,000 different types of trees and shrubs grown in 164 cities in 78 countries – to assess the likely impact. effects of global warming on trees planted along streets and in parks.
Of the 164 cities analyzed, more than half of tree species were at risk in some cities due to rising temperatures and variable rainfall. And by 2050, this ratio is projected to increase to more than two-thirds.
Climate risks to species in urban areas are particularly high in cities in the tropics and in vulnerable countries such as India, Niger, Nigeria and Togo.
In the United Kingdom, researchers looked at five cities: Belfast, Birmingham, Bristol, London and York.
They found that drier weather due to climate change is expected to have a major impact on trees, particularly in York, London and Birmingham..
Perhaps Miss Briggs might want to explain what this ‘dryer weather’ is for!
Last I checked, Kew Gardens was still very green:
And up here in Yorkshire, I can hardly say we’re turning into the Sahara!
How much was Helen Briggs paid to unleash this craze?
