Per capita food waste increases as the age of the household head increases, attributed to older households' purchase of more fruits and vegetables. The largest life cycle greenhouse gases from food waste was 90.1 kg-CO2eq for those in their 60s while the smallest was 39.2 kg-CO2eq for 20s.

Trees might need our help to survive climate change, study finds - Tree ranges are shrinking in response to climate change but failing to expand into cooler, wetter regions. This suggests that forests are struggling to regenerate fast enough to keep up with rising temperatures, wildfires and disease

Using carbon dioxide removal (CDR) for easily decarbonised sectors may make net zero unachievable. Nearly all 1.5°C pathways require CDR for hard-to-abate emissions, so misallocating it risks failure.
