By GREG WALKER AUGUST 16, 2018 15:01:50 In a new report, the Intergovernmental Panel on Climate Change (IPCC) says that climate change will eventually lead to the destruction of all species in the world’s natural grasslands, including grassland biodiversity.
The IPCC’s new report warns that while it is unclear exactly how much global grassland species will be lost from the climate change impacts, the report concludes that ecosystems will increasingly be threatened.
The report comes at a time when the UN is pushing to cut carbon emissions and tackle the problem of water shortages.
The UN Environment Programme has warned that the loss of water-rich wetlands, and the degradation of ecosystems in places like the Middle East and the African continent could leave them with nowhere to go.
However, a number of experts have said that the impacts of climate change on grasslands could be worse than what is currently happening.
A report released by the US Geological Survey earlier this year found that grasslands around the world are already being destroyed by drought and floods due to climate change.
The study found that in the past five decades, grasslands in the United States, Mexico, Australia and Canada have lost more than 100 million hectares of land.
This is more than the total land area lost in all the world, and it’s a greater loss than the land loss in Europe, according to the report.
The number of wetlands in the US has more than doubled since 1990, and is now on track to become the biggest land mass lost in human history, the USGS said.
The grasslands of the world have been damaged by climate changes for hundreds of years.
Some of the worst drought events in the history of the planet occurred during the Medieval Warm Period, when a combination of dry conditions, floods and melting glaciers caused vast swaths of the globe to become uninhabitable.
The Great Drought, which began in the mid-17th century, resulted in the mass extinction of large numbers of animals and plants, and a severe decline in crop yields.
The rapid decline of grasslands has left people living in those areas unable to survive in their natural environment, said Andrew Smith, director of the Centre for Ecological Science at the University of Exeter in the UK.
“Many people are now living in areas where the landscape is in a state of complete destruction,” Smith said.
“If we do not act now, it will be devastating for people in these areas.”
The report’s authors also found that global warming will reduce grassland productivity and species diversity in some areas, leading to the loss not only of biodiversity but also the health of the ecosystem.
“The loss of grassland habitats is likely to result in severe changes in water-quality, salinity, temperature and the number of animals that are living there,” the report said.
In some areas where grasslands have been significantly degraded, grasses are already disappearing.
This includes areas in the Mediterranean, Central Asia, the Middle Eastern and North Africa.
The loss will result in fewer fish and other aquatic species and the loss, combined with other impacts such as flooding and landslides, will have a serious impact on biodiversity in those habitats, the authors said.
There is no consensus among experts about exactly how the loss will affect the ecosystem, but the report found that it will lead to biodiversity loss across the world.
In the past, scientists have estimated the total amount of grass-land species lost globally at about 1.5 billion hectares (4.6 billion acres) by 2100.
The world’s annual grassland cover is estimated to be somewhere between 4.5 and 9.3 billion hectares.
According to the US Environmental Protection Agency (EPA), about 1 billion hectares of grass is now under threat globally.
The scientists said that they are already seeing the results of climate changes, such as increased drought, rising temperatures and melting permafrost.
“It is possible that, in the future, these changes could be more severe than the impacts that we are seeing today,” the authors wrote.
“However, if we do manage to avoid these changes, we can still avoid significant loss of habitat and biodiversity.”
In the future they are looking at more severe consequences for the climate and the biodiversity.
“We have seen that we can have dramatic consequences for grasslands as climate change changes,” Smith told Al Jazeera.
“So what we are really looking at is a much longer-term problem that is more severe.”
