When The World Is Coming to an End – The Impact of Climate Change
The future is about to get much worse for most of us, and the worst is already here, according to new research published on the eve of the world’s annual climate change summit in Lima, Peru.
The findings, published in Nature Climate Change, show that while global temperature rise could be around 3 degrees Celsius (5.7 degrees Fahrenheit) above pre-industrial levels by 2100, the impacts will be much more severe, with a rise of 4 to 6 degrees Celsius per decade, and possibly more.
For many, that means that, by the end of the century, many people will be dead, said Daniel Crampton, a senior scientist at the University of Queensland in Brisbane, Australia, who was not involved in the research.
The researchers also said that while the effects of climate change will vary widely, it will make the world less safe and more dangerous.
The impact of climate-related disasters will increase by 10 to 30 percent, and extreme weather events will increase even more, the authors said.
“Climate change is likely to exacerbate existing and emerging risks such as floods, droughts, desertification, water scarcity, migration, loss of biodiversity and loss of livelihoods,” the authors wrote.
The impacts are likely to be most pronounced in the tropics, the researchers said.
For example, extreme heat and drought in the arid south-east Asia region could lead to mass migration, and could increase the likelihood of a global famine.
“For now, the situation is not much worse than it was before climate change,” Cramton said.
The results, published last month in the journal Science Advances, also highlight the need for action, said the authors.
The scientists say that while climate change may lead to more extreme weather, it also has the potential to lead to a variety of other problems, including rising sea levels, rising seas, increased extreme heat, more intense heat waves and increased extreme cold.
They said it could also have a profound effect on the way the planet works, with impacts that will have “major impacts on the world economy, ecosystems and people’s livelihoods.”
“The impacts on human health and well-being could be profound,” the scientists wrote.
