Climate change brings many societal changes with it. Farmers are especially affected being dependent on weather and constantly looking at climate trends to adapt to changing weather conditions.
Sarah Alexander, executive director of the Maine Organic Farmers and Gardeners Association, said, "One of the most challenging parts of climate change is that it does look different every season."
"We are seeing severe weather on both ends of it. we are seeing drought conditions, but we are also seeing extreme rain events where there is a lot of rain that comes all at once."
Sean Birkel, a Maine state climatologist, says predicting drought is difficult and uncertain.
“The region will get wetter overall, it's just how will the distribution of precipitation change," Birkel said.
Warmer weather is actually well-suited for a lot of crops grown in Maine.
Alexander said, "I think we grow a lot of crops that are really suited to our climate but also we grow a lot of crops that really prefer warmer weather climates, think about things like tomatoes and peppers.
Warmer climates are not only appreciated by the plants, but by pests too.
Alexander continued, "I think the things that will be harder to adapt to are additional pests and diseases that may come with the season, so we see the pests that come up from the south arriving a little earlier each year and farmers will need new situations in terms of adapting disease."
Even though the climate is getting warmer, it doesn’t necessarily mean that the growing season is also getting longer.
"One of the interesting things that we see from the data is that northern Maine in particular even though the summers have gotten warmer including overnight low temperatures, the growing season length hasn't necessarily increased as fast,” Birkel said.
In fact, one of the biggest dangers is an early fall frost.
Birkel said, "If we measure the growing season length based on frost dates, we find there has still been a tendency, particularly in the fall for an early killing frost that for some crops will end the growing season."
Thus, the preparation and climate tracking farmers do are crucial-not being prepared could be costly.
"We don't know what the serve weather impact will be for any given crop but I think crop failure and crop disaster probably is the biggest concern when it comes to climate change," Alexander said.
In the future, Alexander thinks irrigation could help maintain crops better.
"Climate change is here. the farmers see it every day, every season, have been seeing it for a long time and I think it brings a lot of uncertainty and unknowns in terms of what the future will look like, and I think it gives a lot of challenges within any growing season," Alexander said.
Despite the changing climate, Birkel is hopeful.
"I am concerned in that the climate is changing and we are feeling impacts and we will feel more impacts as temperatures increase. I also feel hopeful that we can adapt," Birkel said.
State lawmakers passed the Healthy Soils Program in 2020 to provide farmers with access to resources and to cover the costs of adopting new technologies.
