; Whereas current climate science and real-world observations of the energy imbalance demonstrate that the approximately one degree (1°) Celsius of warming that has already occurred as a result of human-caused climate change is already dangerous and negatively affecting all aspects of our society and our economy; Whereas the last time atmospheric concentrations of CO2 were over 400 ppm, the seas were 70 to 90 feet higher, Greenland had no ice, and coral reefs suffered a major extinction, and similar conditions will result if our Nation does not drastically reduce CO2 emissions and naturally sequester excess concentrations of atmospheric CO2 this century; Whereas climate change is a threat to national security, as it contributes to and exacerbates global instability and conflict; Whereas the generation of today’s children was born into a climate system made hazardous to their health and well-being because of human-caused climate change; Whereas children are uniquely vulnerable to human-caused climate change because of their developing bodies, higher exposure to air, food, and water per unit body weight, unique behavior patterns, dependence on caregivers, and longevity on the planet; Whereas human-caused climate change is a public health emergency that is adversely impacting the physical and mental health of children through, among other impacts, extreme weather events, rising temperatures and increased heat exposure, decreased air quality, altered infectious disease patterns, and food and water insecurity; Whereas infant mortality increases 25 percent on extremely hot days, with the first 7 days of life representing a period of critical vulnerability; Whereas heat illness is a leading cause of death and illness in high school athletes, with nearly 10,000 episodes occurring annually; Whereas 8.4 percent of children suffer from allergic rhinitis and the ragweed pollen season in North America has grown 13 to 27 days longer since 1995 due to higher temperatures and greater CO2 levels
