  • Yes you are right. There are many research paper writing services available now. But almost services are fake and illegal. Only a genuine service will treat their customer with quality research papers. ⇒ www.WritePaper.info ⇐

  • If you’re looking for a great essay service then you should check out HelpWriting.net. A friend of mine asked them to write a whole dissertation for him and he said it turned out great! Afterwards I also ordered an essay from them and I was very happy with the work I got too.

Climate Change Science and the IPCC

  1. 1. Climate Change Valérie Masson-Delmotte valmasdel #showyourstripes
  2. 2. • Climate is changing everywhere, with visible impacts • This is due to global greenhouse gas emissions • On the near-term (horizon 2050), future changes are inevitable and we must be prepared to reduce risks • Long-term changes (beyond 2050) depend drastically on greenhouse gas emissions in the next years and decades • There are many options to act
  3. 3. A major scientific endeavour 17th C Weather instruments 19th C Networks Ice ages Greenhouse effect Fluid physics Thermodynamics Radiative transfers 20th C Past climate Climate modelling Chronology, proxies Super computors Satellites

  21. 21. www.ipcc.ch/report/SROCC Sea level rise risks depend on emissions and on response options
  22. 22. What are plausible futures?
  23. 23. Today’s choices determine future risks Fast reduction of emissions Large increase of emissions Late reduction of emissions 2019 Delayed action
  24. 24. If not us, who? If not now, when?
  25. 25. If not us, who? If not now, when? • There are many options for action, and this requires new mindsets and new skills (« climate literacy ») - not just awareness raising, but skills - systemic vision (beyond usual silos) - understanding science (Earth system) - understanding societal implications - systems transitions (energy, land use, urban, industry, finance) - societal transformation (law, best practices, demand side) - potential and limits, co-benefits and trade-offs, enabling conditions - building resilient, carbon neutral development pathways • Training teachers www.oce.global • Monitor, assess, benchmark « climate literacy »
  26. 26. If not us, who? If not now, when? • Research and action to support transitions and transformations • Agenda of research and action for cities and climate change • Cultural heritage and climate change • Transforming universities, living labs of transitions : - Environmental & carbon footprints - Open data and student projects - Researchers engaged with society - Vision, targets, pathways, implementation - Net zero emissions and resilience - International benchmarking - Creativity www.ipcc.ch/report/SR15 and data.ene.iiasa.ac.at/iamc-1.5c-explorer labos1point5.org futureearth.org/2019/09/20/global-research-and-action-agenda- on-cities-and-climate-change-science-published/ www.icomos.org climateheritage.org
