When we, as human beings, get a fever, we immediately get worried and take action. After all, we know that if our body temperature rises to 1.5ºC, let alone 2ºC [3.6 ºF] above the normal average, there can be severe damage, while an increase of 4-6ºC [7.2-10.8 ºF] or more can cause a comatose situation and even death.
So it is, when planet Earth gets a fever. For the past 11,000 years, the average temperature of the Earth has been around 14ºC [57.2ºF]. It is now about to reach an increase of 1ºC. And, if we do not take appropriate measures now to stop this fever from spreading, the forecast is that our planet will be well on its way to anywhere between 2ºC to 6ºC rise in temperature before the end of this century. Under such feverish conditions, life as we know it will dramatically change on planet Earth.
We have no other recourse but to take action now. Not just any action but the right action and at the right time. When, for example, a human person has a fever, we urge them to rest their body, give them a lot of liquids, prescribe the right medicine, and if the fever goes up we bring them to the hospital and try to find the underlying cause of the fever, which can range from a simple infection to life-threatening diseases like cancer.
