Some scientists have hypothesized that higher concentrations of GHGs in the Earth's atmosphere could result in climate changes that have significant physical consequences, such as increased frequency and severity of storms, droughts, floods, and other climatic events. If these physical effects were to occur, they could have adverse effects on Greylock Productiona's assets and operations and result in expenses for preparing and responding to them, as well as an increase or decrease in energy requirements as a result of extreme weather conditions depending on the duration and magnitude of such conditions.
