Temperature

Since 1901, temperatures have risen in many parts of the world. Since 1970, the pace of this trend has accelerated. Increases in average global temperatures are expected to be within the range of 0.5°F to 8.6°F by 2100, with a likely increase of at least 2.7°F for all scenarios except the one representing the most aggressive mitigation of greenhouse gas emissions according to IPCC (2013). High and low temperatures are also predicted to increase, which may have negative consequences for agricultural production and forest heath. Increasing high temperatures can hurt both crop pollination and fruit development. While crop growth can continue at high daily maximum temperatures, fruit production and pollination are more sensitive. The end result may be lower yields of marketable crops, and reduced income for farmers. 

Warmer temperatures around the globe lead to stronger storms and heat waves, and more of them. Though there will likely be more average rainfall world-wide, some areas can expect to see a greater increase than others. Higher temperatures in some regions areas will intensify drought. This may increase the need for irrigation and other adaptive practices on farms.

An Economic Case Study at Intervale Community Farm After severe drought in much of the Northeast in 2016, the following summer reminded us that the trend in the Northeast is for more rainfall. However, this rain is more often occurring in heavy downpours between periods of hot…

Mid-Atlantic corn and soybean yields show great variability in response to precipitation during critical growth stages. Long-term agricultural research provides unique insights into the impact of climate and weather on agricultural sustainability. The USDA-ARS Farming Systems…

A project designed to build a virtual consortium of Masters and Doctoral students working on climate adaptation in agriculture and forestry. Nominated by a university partner within the USDA Northeast Climate Hub network, GradCAP scholars work with Climate Hub leadership,…

How are climate change and weather variability affecting Northeastern producers? Farmers, foresters, and other land owners in the Northeast are already feeling the pressures of a changing climate and increasing weather variability. In recent years the Northeast has experienced…

How does the changing climate impact dairy operations, and what can dairy farmers do to adapt?  Increased heat stress in dairy livestock can reduce feed intake, milk production, and livestock fertility. For a Southern Pennsylvania farm, average annual losses in milk production…

Across New England “Low-volume” roads provide a critical transportation link for rural communities and commerce. “Low-volume” roads are roads with traffic volumes generally less than 400 vehicles per day. They often provide access to forests for logging and other forest…

This growing network of climate-informed demonstration sites is designed to take you to the field and make you feel 'As If You Were There.' Field tours are a powerful teacher because they are an ideal way to see how farm and forestry practices work in the real world. Consider…
