1. Human interference with the climate system is occurring and climate change poses risks for human and natural systems.
2. In recent decades, changes in climate have caused impacts on natural and human systems on all continents and across the oceans.
3. In many regions, changing precipitation or melting snow and ice are altering hydrological systems, affecting water resources in terms of quantity and quality.
4. Many terrestrial, freshwater, and marine species have shifted their geographic ranges, seasonal activities, migration patterns, abundances, and specific interactions in response to ongoing climate change.
5. Based on many studies covering a wide range of regions and crops, negative impacts of climate change on crop yields have been more common than positive impacts.
6. Differences in vulnerability and exposure arise from non-climatic factors and from mulitdimensional inequalities often produced by uneven development processes.
7. 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.
I had the opportunity to be on Hofstra's WRHU Morning Show this morning with the lead author of the report, Christopher B. Field, to discuss the report. It was an honor to be on the show with him. One of the things he stressed is that the report is based on many thousands of research papers and governmental reports. One of the hosts of the show noted how we are definitely past the days when we can be in denial on climate change and its impacts. We just now have to figure out how to live with it while working on reductions in greenhouse gas pollution.
