Memorandum for the Petitioners 1119 There is clear link between respondent Carbon Majors’ climate pollution and the impacts occurring globally and in the Philippines 8.137. There is a clear link between the concentrations of GHGs in the atmosphere and the median surface global temperatures, as well as ocean acidification.564 There is also clear link between respondent Carbon Majors climate pollution and global impacts, such as surface temperature and sealevel rise, which in turn is resulting loss and damage in the Philippines.565 Scientists seek to establish a high-level of certainty, at least 90% certainty, a standard much higher than the “ balance of probabilities” test used for civil matters in most jurisdictions (See Part V [C to C. l ]).566 r r 8 . 138 . As mentioned above, it is possible to identify and quantify the contributions to global temperature change and sea-level rise to emissions generated by products produced and marketed by specific major investor-owned companies such as respondents herein providing a potential framework for the apportionment of responsibility for climate-related harm .”567 — 8.139. Dr. Ekwurzel answered the Honorable Commission’s question on how to use scientific evidence to show the causality between the Carbon Majors’ climate pollution and climate impacts globally and in the Philippines. In her answer, Dr. Ekwurzel explained that the scientific study 568 she co authored helps to establish a clear link between the respondents’ emissions, based on the Carbon Majors data , and the climate impacts through wellestablished climate models used by the IPCC . By running the model, this enabled them to see “how much cooler the surface temperature earth would have been in 2010, see how much lower the seas would have been” without the emissions from the specific companies. This process makes it possible to attribute to specific companies an amount of change in temperature and sealevel rise.569 8.140. As shown, the proportional increase in atmospheric carbon dioxide, GMST and GSL rise key climate impacts - can be traced to the emissions of the major carbon producers.
