  2. Aug 7, 2018 · Hothouse Earth is a term used to describe a scenario in which human activity causes a higher global temperature than at any time during the past 1.2 million years, due to a breakdown in the...

  3. Aug 7, 2018 · As the world gets hotter due to heat-trapping carbon emissions, there's worrying evidence that melting permafrost soils are releasing even more carbon into the atmosphere – making a bad situation potentially catastrophic.

  4. Aug 6, 2018 · Flooding and coastal erosion may be a major problem in a warmer world. According to the research paper, crossing into a Hothouse Earth period would see a higher global temperature than at any...

  5. Aug 9, 2018 · A new scientific paper proposing a scenario of unstoppable climate change has gone viral, thanks to its evocative description of a “Hothouse Earth”. Much of the media coverage suggests that we ...

    Put simply, climate scenarios ask crucial questions like ‘what can happen?’ and ‘what should happen?’ The scenarios are like key pieces of a mosaic that offer glimpses into possible futures. In this way, it is possible to look up the expected economic loss for a specific country – let’s say Spain or Morocco in any year between now and 2100 – under ...

    The framework explores a set of six scenarios (see Chart 1). Orderly scenarios assume that governments introduce ambitious climate policies immediately and gradually, which will keep both physical and transition risks at bay. Disorderly scenarios explore higher transition risks when climate policy responses are uncoordinated or delayed. And hot-hou...

    The work on the scenarios needs to evolve further to be useful for other new challenges as well. The turmoil in energy markets and the Russian war against Ukraine show that we need to prepare for unpredictable risks in the near future. We need to better assess the consequences of natural disasters to inform policy analysis and stress testing exerci...

  6. As greenhouse gas emissions trap heat, atmospheric temperatures rise, causing a new risk to emerge. We are not only reaching higher temperatures than any point in the last 1.2 million years, but we might push Earth’s climate into something called the Hothouse Earth trajectory.

  7. Aug 6, 2018 · A study published in Proceedings of the National Academy of Sciences shows that there is a risk of Earth entering “Hothouse Earth” conditions where the climate in the long term will stabilize at a global average of 4-5°C higher than pre-industrial temperatures and sea level 10-60 m higher than today.
