Oil majors' climate visions 'inconsistent' with Paris targets

Global decarbonisation scenarios envisioned by oil and gas majors are incompatible with the Paris climate deal temperature goals aimed at averting devastating heating, according to research published Tuesday.. They also assessed the underlying energy system changes that drive emissions and could lead to a given scenario meeting -- or failing to meet -- the Paris temperature goals.

Space mission shows Earth's water may be from asteroids: study

Water may have been brought to Earth by asteroids from the outer edges of the solar system, scientists said after analysing rare samples collected on a six-year Japanese space mission.. The scientists hypothesised that such material probably has an "outer Solar System origin", but said it was "unlikely to be the only source of volatiles delivered to the early Earth".

Tibetan Plateau water stores under threat: study

The Tibetan Plateau will experience significant water loss this century due to global warming, according to research published Monday that warns of severe supply stress in a climate change "hotspot". . They found that due to an increasingly warm and wet climate, the Tibetan Plateau has lost just over 10 billion tonnes of water a year since 2002.
