Trees are 'getting shorter due to climate change'

Daily Mail  

Trees are getting shorter due to climate change with their size dropping drastically over the last century alone, a landmark study has claimed. Meanwhile, rising carbon dioxide levels have offered little respite to older trees as they only increase growth in young forests with abundant nutrients and water. The introduction of managed woodland, pictured, will also change the appearance of these habitats as fewer older trees will be present The University of Birmingham's Dr Tom Pugh said: 'This study reviews mounting evidence that climate change is accelerating tree mortality, increasingly pushing the world's forests towards being both younger and shorter. 'Increasing rates of tree mortality driven by climate and land-use change, combined with uncertainty in the mix of species that will form the next generation, pose big challenges for conservationists and forest managers alike.'

We’ve discovered the world’s trees absorb methane – so forests are even more important in the climate fight than we thought

Tree bark in the world’s forests absorbs the greenhouse gas methane, my colleagues and I have demonstrated for the first time on a global scale – a discovery that could have big implications for tackling climate change. But now, our large-scale study proves that there’s another way that trees absorb greenhouse gases – so forests can provide even more climate …

Researchers have found that in tropical forests, such as this one in Brazil, a leaf’s ability to produce oxygen and convert sunlight to energy begins to collapse at around 116 degrees. “Photosynthesis typically starts to decrease at much lower temperatures than 116 degrees, but that is fully reversible,” said Martijn Slot, a study author and forest ecologist with the Smithsonian …
