Many studies have looked at whether there is a correlation between boron levels and climate change, one found that the correlation to be positive. This means that as boron goes down, climate changes negatively because of increasing global temperatures. It's suspected that many plants use boron as a defense against herbivores, pests and pathogens; decreasing quantities can harm plant health leading to increased population rates of these organisms which could in turn create an unstable ecosystem.
Scientific evidence also suggests that warmer climates speeds up natural processes like wind and water erosion which would lead to higher concentrations of dissolved solids (which points to more dissolved nutrients) which has been identified as another impact on plants using boron for defense.
