It is indisputable that global warming has become one of the most pressing issues of our time and that urgent action needs to be taken in order to protect our planet and its inhabitants. Unfortunately, however, we are arguably not doing enough to counteract the effects of global warming, presenting a real threat to our environment and our future.
Let us first look at some of the stark facts. Global temperatures have risen by 1.1°C since 1880, and the impact of this warming has been felt throughout the world in terms of increased heat waves, floods and extreme weather events. Sea levels have risen by 8 inches, and are predicted to rise by an additional 6.5 to 9.8 feet over the course of the century. The Arctic has warmed by more than twice the global average, with winter temperatures rising by a startling 5.4°C. This kind of consistent, extreme and accelerated warming is utterly unprecedented in human history and appears to be directly linked to anthropogenic activity, such as the burning of fossil fuels and emissions of greenhouse gases.
Despite this, humanity is still largely failing to take meaningful action to tackle the causes or consequences of global warming. Admittedly, some progress has been made in reducing emissions, but this has so far been inadequate to reverse the long-term trends. Promises made under the Paris Agreement have been ineffective, with most signatories not even meeting the inadequate reduction targets set out in the document. Furthermore, we have little idea about what concrete steps we need to take in order to restore the global climate.
The inaction of political and industrial leaders is only perpetuating the cycle of climate change and necessitating increasingly drastic interventions in order to halt the process. For instance, the ‘Solar Radiation Management’ method of geoengineering states plans to inject aerosols into the atmosphere in order to dim the Sun’s radiation and reduce global warming. Whilst this may result in the short-term reduction of global temperatures, the long-term consequences of such measures are unknown and could be dire. Although this type of measure should not be dismissed entirely, it may be preferable for governments and corporations to reduce their emissions drastically if we are to properly tackle the issue of global warming.
Ultimately, global warming will only be solved if political and economic decision-makers make real commitments to change the current system and actively encourage the transition to renewable sources of energy. It may also be necessary to incentivize consumers and businesses to make the switch, through subsidies, tax credits and other financial measures. To effectively combat the effects of global warming, it is essential that the international community rallies together to develop a multifaceted solution which encompasses meaningful emissions decreases and the development of renewable energy sources. Without substantial intervention, global warming continues to be a pressing and ever-present challenge.
We must accept responsibility for our actions and create a sustainable future by implementing real emissions reductions, developing renewable sources of energy and encouraging everyone to make the sustainable choice. Only then can we hope to save our planet and secure a vibrant future for generations to come.
