With the veritable amount of evidence that has been laid out before us, why is it that people aren’t concerned about global warming? Despite scientific consensus on the subject, some people think global warming isn’t happening at all. There are several reasons for this, and they cover various overlying and conflicting themes on global communication, and an incentive towards environmental action.
Beginning with the common lay-person, a popular speculation is formulated in the form of this question: If simple forecasts can’t get next week’s weather right, how is it that we can trust the predictions that have been made on the basis for decades or centuries from now?
The answer to this is quite simple, and once again highlights the necessity towards scientific communication, and public education. Weather and climate are not the same. Weather relates to individual, and day-to-day changes in the atmosphere; climate is the statistical average of such changes. Weather is short-term, and of a chaotic nature, thus making it inherently unpredictable beyond a few days. Meanwhile, climate is long-term average weather, controlled by the composition of the atmosphere, and is thus more predictable on the time-scales considered. A simple analogy is provided at the Climate Communication website,
While it is impossible to predict the age at which any particular man will die, we can say with high confidence that the average age of death for men in industrialized countries is about 75. The individual is analogous to weather, whereas the statistical average is analogous to climate.
Stepping beyond the individual, we encroach upon a global dialogue between, and within political and scientific institutions. While most scientists recognize the phenomenon that is global warming, there still remain a few who believe that there is nothing to be worried about. The latter argue that the Earth is more resistant to climate change than proposed. Many of the consequential changes are, in their opinion, not disastrous, and that cutting down the emission of greenhouse gases may result in economic damage far more potent than any of the effects of global warming.
The uncertainty that exists within the scientific community has been carried over to the political realm. Skeptics use it to argue for postponing action, while contenders point out that there are various other facets of life that require action in the face of uncertainty, such as buying health insurance. The IPCC has also pointed out that confronting a large-scale task such as climate change will not occur in an economic dissolution. As quoted from the 2014 report by the IPCC’s Working Group III,
Climate policy intersects with other societal goals, creating the possibility of co-benefits or adverse side effects. These intersections, if well-managed, can strengthen the basis for undertaking climate action.
Ultimately, what can we do about it? It isn’t possible to simply “stop” climate change. Even if we turned off every fuel-burning machine on Earth, the planet would warm at least another 0.5 degrees Celsius as the climate adjusts to the greenhouse gases that already have been emitted. Nevertheless, progressing toward the future, we can still make efforts in decreasing activities that may help propagate and positively reinforce global warming.
On a local level, we can do this basically by not using as much of the stuff that creates greenhouse gases as well as using less energy. Electricity governs much of the modern world, and much of the electricity that operates many of the devices in our homes comes from a power plant, which most likely burns fossil fuels to generate that power. The simple action of turning off lights when they are not in use, and using a fan or an air-conditions only when necessary can help. Similar initiatives can be taken in the view of using public transportation, efficient recycling and waste management, reforestation etc. Beyond all of this, we need to develop non-fossil fuel energy sources. Hydro-electric power, solar power, hydrogen engines, and fuel cells could help in this initiative towards a global change in energy sources.
In conclusion, much of this is easier said than done but that doesn’t mean we should give up. Given the global nature of the climate problem, we all have a hand in contributing to the solution, and in confronting the necessary alternatives and options we must also be willing to face agreements and disagreements in faith of positive communication. The real power to enact significant change rests in the hands of those who devise national and global policies. International and scientific collaboration on technology sharing, effective communication and education of the public supplemented by an efficient transition toward alternative, and green-energy initiatives would help make a difference in the long run.
