For the nation’s 2.4 million farmworkers, climate change is poised to exacerbate the harms of pesticides, a growing body of research shows.

Heat stresses the body, making it more vulnerable to pesticides and other toxicants, and protective clothing worn in the heat only adds to this stress. Hotter temperatures can also lead to higher evaporation rates, increasing farmworkers’ exposure as more pesticides are applied to crops. And heat can boost rates of chemical transformation of pesticides into more toxic compounds.

“When it’s in the air, you are inhaling it through your nose. You are exposed to it through your other organs like skin. Your skin can absorb some of the pesticides [that are] in the air, and also when you’re sweating as part of doing your work you are increasing the pore size of your skin,” said Omanjana Goswami, a scientist in the food and environmental program at the Union for Concerned Scientists, an advocacy group. “It is awful. There is no other word for it.”

It’s been a wild first half of the year in the US power sector, with announcements of gigantic natural gas power plants and some long-awaited renewable energy projects coming online.

At times of rapid change, forecasting is difficult. So I feel a measure of comfort focusing on something concrete like the list of 368 utility-scale plants that began operation from January to June, according to data from the US Energy Information Administration. The group is dominated by utility-scale solar.

This is a top-heavy list, led by SunZia Wind South and SunZia Wind North in New Mexico, which went online this spring and are the largest wind farms in the country, with a combined generating capacity of 3,650 megawatts. SunZia has been in the works for about a decade and arrives at a time when US onshore wind power development has dwindled for a host of reasons related to regulations and public opinion.
