The problem is real: The incremental increase of CO2 concentration in the atmosphere has led to global warming and climate change. Why? Because “CO2 causes warming, it’s basic physic that has been known for more than a century, it’s pretty straightforward – If you put more CO2 and other greenhouse gases into the atmosphere it will get warmer, there’s no way around”, said Professor Eric Wolff, University of Cambridge.
Why should we care?
Global warming and human-induced climate change are dangerous threats to human existence. Scientists and researchers, for instance, Colin et al. (2015), have been arguing that the current Syria civil war and refugee crisis are results of a historic drought caused by climate change and global warming in the region. The drought was identified as the main cause of the shocking mass migration to Syrian urban areas, which resulted in resources constraints, unemployment, crimes and civil conflicts. What happens in Syria today demonstrates a possible dark future of humanity if climate change and global warming are unstoppable.
However, since 1988, CO2 concentration in the atmosphere has been continuously higher than the upper safety limit, which is 350 parts per million (ppm) and has increased by more than 2% every year (Hansen et al., 2010). According to CO2NOW (2014), 91% percent of humanity’s CO2 in 2010 came from fossil fuels burning and cement production; the rest came from land use change and deforestation. To break down further, 2013 CO2 emissions were constituted by coal (43%), oil (33%), gas (18%), cement (5.5%) and gas flaring (0.6%).
Good news: There are solutions. For instance, one of the critical solutions to reduce CO2 concentration in the atmosphere is to replace all current fossil fuels based vehicles with the next generation of transportation that is powered by renewable energy. The systematic solution should be a completed product-service cycle, in which includes: sustainable energy generation, energy storage (battery), electrical automotive design and manufacturing, infrastructure, recycle. Sustainable energy generation such as the wind and solar, and energy storage on a larger scale can also serve as alternatives to traditional energy solutions – coal, natural gas, nuclear, hydro. “No incremental CO2, that’s the future we need to have”, Elon Musk, CEO of Tesla (2015) addressed in the debut event of Tesla power-wall, the battery pack that stores energy generated by solar panels.
