A state-of-the-art climate model, funded by the #LeonardoDiCaprioFoundation and released by the prestigious scientific publisher #SpringerNature, offers a roadmap for meeting -- and surpassing -- the targets set by the #ParisClimateAgreement, showing that #wecansolvetheglobalclimatecrisis with currently available technologies and natural climate solutions. The book, entitled #AchievingtheParisClimateAgreement, was the culmination of a two-year collaboration with 17 leading scientists at the #UniversityofTechnologySydney (UTS), two institutes at the #GermanAerospaceCenter (DLR), and the #UniversityofMelbourneClimate&EnergyCollege.
As the #IntergovernmentalPanel onClimateChange (IPCC) warned in its #SpecialReportonGlobalWarming of 1.5°C (SR1.5) released #October2018, the Earth must be kept below the dangerous threshold of 1.5°C in global average temperature rise above pre-industrial levels if we are to avoid a worsening of #climaterelatedimpacts. We are already seeing the #devastatingconsequences of the current 1°C global temperature increase, including rising sea levels in many coastal cities, extreme storms, prolonged droughts, and intensified wildfires.
The impacts resulting from a higher 2°C level are almost unimaginable -- the #deathofthecoralreefs in every ocean, the #collapseofnearlyonequarteroftheworldsagriculturalland, dramatically increased heat waves and wildfires, #100milliondriventoextremepoverty sparking multiple refugee crises; and more than #$11trillionperyearindamages from extreme storms and flooding. Stacked upon each other, these impacts and many more, could #underminetheveryfabricoflife on our planet, greatly challenging the continuation of human civilization as we currently know it.
Up until now, it was assumed to be difficult if not impossible to achieve the carbon budget required to stay below 1.5˚C -- equivalent to approximately 320 billion tonnes (Gt) of net carbon dioxide emissions (CO2) above early 2018 levels*. Humans today release approximately 40 GtCO2 per year, mostly from the burning of fossil fuels – coal, oil, and natural gas. At our current level of emissions, we would only have 7 years to completely cease the use of all ⬇
