Despite the fact that food is a big climate problem, very little has been done so far to address it. This year's U.N. climate conference in Dubai will be the first to dedicate a whole day to the ...
But little progress has been made, as shown by severe ecological footprint overshoot and lack of sufficient progress on the climate change problem. Something within the human system is preventing change to a sustainable mode of behavior. That system trait is systemic change resistance. Change resistance is also known as organizational ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The depressing thing is, these are just a few of the foods and drinks that could be impacted by climate change. From rising temperatures to deforestation, there are a variety of reasons why some ...
