There is a controversial method of cutting greenhouse gas emissions called climate engineering. Climate engineering would lower climate temperatures by reflecting the run's radiation back into space, which will possibly be made done through changing cloud forms, or repecating particles that cover the atmosphere casued by volcanic eruptions.It is hoping to limit global warming to under two degrees and is said to be rapid and cost effective, though uncertainties are still present. It is possible that there may be side- effects and if they are to arrise, the method would have to be stopped suddenly, assuming it is possible to do so. Side effects may include the weakening of monsoon rains and food production in Asia and Africa. If it were a necessity to end the climate engineering, this too would lead to significant climate change and many ecosystems would struggle to adapt.
Though climate engineering has the potential to halt global warming, the side effects are too unknown at this point to risk the use of such a method. https://www.sciencedaily.com/releases/2016/12/161208085848.htm

Prairie cordgrass is an especially durable plant, able to withstand the effects of flooding, salt stress, and now newly discovered, freezing. The discovery that the grass can withstand freezing is so important becasue it provides an insight to engineering freeze tolerant plants. When a plant is exposed to temperatures at freezing point, crystals form and burst the living cell. Cordgrass, however, quickly pumps ions to the outside of the cell, keeping the crystals from forming. Scientists are just beginning to unravel the genetic mechanisms in order to understand how the cordgrass is able to react in a way that preserves its state. There are hopes that wth further knowledge, the concept can be used towards other crops such as corn. With a longer planting season and resistance to frostbite, more successful seasons may be possible. https://www.sciencedaily.com/releases/2016/11/161129133631.htm |
