Climate Change: 15000 scientists unite to give a second warning
A consortium of over 15000 global scientists on Tuesday gave the world a second warning that time is running out to save the Earth. The scientists said that urgent action must be taken to avoid substantial and irreversible harm to the planet.
New Delhi : A consortium of over 15000 global scientists on Tuesday gave the world a second warning that time is running out to save the Earth. The scientists said that urgent action must be taken to avoid substantial and irreversible harm to the planet.
In 1992, a majority of the worlds living Nobel Laureates united to sign a warning letter about the Earth.
Twenty-five years later, today, scientists have taken grassroots action, with a scorecard showing that of nine areas only one has improved: our ozone.
The article, "World Scientists Warning to Humanity: A Second Notice", has been co-signed by over 15,000 scientists in 184 countries and was published on Tuesday in the journal BioScience.
The initial warning 25 years ago identified trends that needed to be reversed to curtail environmental destruction, including ozone depletion, forest loss, climate change and human population growth.
"In this paper we look back on these trends and evaluate the subsequent human response by exploring the available data," Thomas Newsome, a research fellow at Deakin University and The University of Sydney in Australia, said.
According to Newsome, this was possibly the biggest number of signatories to any published scientific paper.
"It is an overwhelming response we did not quite expect," said Newsome.
The research article highlighted the negative 25-year global trends, including a 26 per cent reduction in the amount of fresh water available per capita and a loss of nearly 300 million acres of forestland.
It also noted that there has been a collective 29 per cent reduction in the numbers of mammals, reptiles, amphibians, birds and fish and a 75 per cent increase in the number of ocean dead zones.
The research article states there is still time but notes the areas that need to be improved, including promoting dietary shifts away from meat, encouraging the adoption of renewable energy and limiting human population growth.
