Probability and Cost Estimates for Climate Change

by Sam Peterson

As the scientific consensus regarding the existence of climate change has grown, two separate, research communities have delineated differences in experimentation and modeling of climate change costs. The “integrated assessment community” has extensively examined the influence of “technological and socio-economic uncertainties on low-carbon scenarios,” while the modeling community has focused on understanding the “geophysical response of the Earth system to emissions of greenhouse gases.” Rogelj et. al. (2013) unite these two seemingly mutually exclusive endeavors by generating “distributions of the costs associated with limiting transient global temperature increase to below specific values, [and] taking into account uncertainties in four factors: geophysical, technological, social and political.” The study concludes that political choices that delay mitigation have the largest effect on the cost–risk distribution, closely followed by geophysical uncertainties.

Improving Food Yield in Africa

by Tyler Dean

According to an article in Appropriate Technology in 2014, climate change is predicted to increase the number of malnourished people in Sub-Saharan Africa by nearly forty percent by 2050, from the current 22 million, to 355 million. In East and Central Africa, suitable areas for growing beans could decline up to eighty percent, while areas suitable for growing bananas could decline twenty-five percent. In aggregate, climate change will severely lower crop yields by adversely affecting the length of the growing season and rainfall. It is crucial for African farmers to switch to “climate- smart agriculture”(CSA). CSA will increase resilience by allowing farmers to adapt to climate change and reduce their greenhouse gas emissions. The government has implemented monitored subsidy programs, consultants and aggregators in order to improve production and instill confidence in Africa’s farmers. Continue reading

Using Cloud Computing to Monitor Climate Change

by Tyler Dean

The department of Biomedical Engineering at the Adhiyamaan College of Engineering has proposed a system that provides monitoring benefits to a large number of users by deploying a collection of observed data over a long period of time. The system uses a combination of advanced technologies to collect comprehensible environmental data that can be accessed from any location online. The system requires sensors for air pollution, temperature and humidity of a selected place. The data acquisition system acquires the data of temperature, humidity, pollution of air including Illumination, dust, carbon dioxide, ultraviolet, wind direction, wind speed, air pressure and the altitude from remote sensing areas .The system can be used for intrusion detection, used to remotely monitor the conditions of a place, to determine the habitat of a place and to field conditions to specify which cultivation is suitable for a region.
