Climate Change Affect Plants EssayHistorical climate change has had a profound transaction on current biogeography, so we can expect our ongoing and rapid climate change, to have as great an effect. Climate change has important implications for or so every aspect of life on Earth, and effects are already being felt. * Temperatureeffectsaverage, minimum or maximum can be important determinants of bring distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem is susceptible to frost.Conversely, boundaries mingled with vegetation types (e. g. Arctic treeline) are principally determined by summer warmth * Rainfall is also an important determinant for example it affects the balance of grasses to woody vegetation * Other factors such as soil type or herbivory may also be affected by climate change. Effects on Plant Diversity * Species left base as they are unable to change distribution fast enough. Species with long life cycles and/or slow dispersal are particularly vulnerable. Some apart(p) or disjunct species are particularly vulnerable, as they may have nowhere to go. These include Arctic and alpine species, and Island endemics Coastal species which will be squeezed between human settlements and rising sea levels.* Plant genetic composition may change in response to the selection pressure of climate change. * Some launch communities or species associations may be lost as species move and adapt at different rates. Increased invasions by alien species may occur, as conditions suit more suitable for exotic species whilst native species become less well suited to their environment (for example, Bromus is more invasive in wet days (Smith et al, 2000)). This is especially true given human interventions which have deliberately and accidentally facilitated the spread of species across the globe. * Many plant communities act as sinks (store vitamin C), which helps to offset carbon emissions. However, over the next 70 years, the effects of climate change on plants mean many terrestrial sinks may become sources.
