"Impacts from recent climate-related extremes, such as heat waves, droughts, floods, cyclones, and wildfires, reveal significant vulnerability and exposure of some ecosystems and many human systems to current climate variability (very high confidence). Impacts of such climate-related extremes include alteration of ecosystems, disruption of food production and water supply, damage to infrastructure and settlements, morbidity and mortality, and consequences for mental health and human well-being. For countries at all levels of development, these impacts are consistent with a significant lack of preparedness for current climate variability in some sectors."
Unfortunately, though clear cut and definitive, statements like this trigger anxiety, guilt, denial, or sadness. Fortunately, for some, they trigger opportunity - an opportunity to make a difference. Even small differences added together make things happen.
