Giaever also disputed the significance of the measured 0.8 °C average global surface
warming over the past 130 years, comparing it to a
human fever and the temperature at which he had to maintain
tissue for cell growth during his own biophysical experiments, also showing the following slide:
Criteria Description Fish Toxicity Measure of the acute toxicity to fish (both saltwater and freshwater) Daphnia Toxicity Measure of the acute toxicity to Daphnia (invertebrate aquatic organisms) Algae Toxicity Measure of the acute toxicity to aquatic plants Persistence / Biodegradation Rate of degradation for a substance in the environment (air, soil, or water) Bioaccumulation Potential for a substance to accumulate in fatty
tissue and magnify up the food chain Climatic relevance Measure of the impact a substance has on the climate (e.g., ozone depletion, global
warming, etc.) Other Any additional characteristic (e.g., soil organism toxicity, WGK water classification, etc.) relevant to the overall evaluation but not included in the previous criteria 1.3.3 Material Class Criteria The following material classes are flagged due to the concern that at some point in their life cycle they may have negative impacts on
human and environmental health.
