A new study has revealed that it might have been human activity which is responsible for the decline in number of cheetahs.
Human activities are directly responsible for rising levels of atmospheric water vapour, the most abundant greenhouse gas and a key driver of global warming, scientists say.
The rising levels of water vapour in the upper troposphere - a key amplifier of global warming - owing to greenhouse gases will intensify climate change impacts over the next decades, scientists said.
Contrary to the current belief that about half of earth`s plants and animals would go extinct over the next century because of human activities, a study has found that this extinction rate is overly exaggerated.
A new study has shown that aerosols in the atmosphere produced from human activities tend to weaken hurricane or tropical cyclones.
Sumatran tigers - the tiger specie found only on the Indonesian island of Sumatra - is on the verge of extinction due to high levels of human activities, a new research has suggested.
Human-induced activities may be destabilising desert ecosystems across the world, a new study has claimed.
