Changing climate will have both beneficial and harmful effects on farming, but the net effect is unknown. Longer frost-free growing seasons and higher concentrations of atmospheric carbon dioxide would increase yields for many crops during an average year, notably soybeans.
Alpine plants are one group expected to be highly susceptible to the impacts of climate change (Logan Pass, in Montana, United States). There is an ongoing decline in plant biodiversity, just like there is ongoing biodiversity loss for many other life forms. One of the causes for this decline is climate change.
High wheat prices caused by the drought have discouraged farmers from investing in alternative drought-tolerant crops. [87] The United States Drought Monitor observed "extreme drought" conditions in much of the eastern half of Massachusetts, southeastern New Hampshire and the southern part of Maine in September 2016. [88]
Heavy rain over the winter eased the drought in the West, but now the middle of the country is extraordinarily dry. “It comes across the Mississippi River and then just disappears,” Shane, 47 ...
Crop yield is also negatively effected by drought stress, the reduction in crop yield results from a decrease in photosynthetic rate, changes in leaf development, and altered allocation of resources all due to drought stress. [72] Crop plants exposed to drought stress suffer from reductions in leaf water potential and transpiration rate.
The effect of increased levels of atmospheric carbon dioxide on the nutritional quality of plants is not limited only to the above-mentioned crop categories and nutrients. A 2014 meta-analysis has shown that crops and wild plants exposed to elevated carbon dioxide levels at various latitudes have lower density of several minerals such as ...
As nearly 40% of the country is currently in drought, scientists are looking to the largest rodent in North America for help: the beaver.Researchers in California and Utah found that dams made by ...
Winter drought is hidden, said Wisconsin state climatologist Steve Vavrus, because most people don't notice dryness outside the growing season. A third of Wisconsin is still in drought. What does ...
