Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-twentieth century and its projected continuation. The term ‘global warming is a specific example of global climate change. In common usage, the term global warming refers to the warming in recent decades and implies a human influence. According to one of the most detailed ecological studies of climate change, global warming is already directly affecting the lives of animals and plants living in various habitats across the world. Scientists say that even the small increase of 0.6C over the past 100years in the global average temperature has left a major imprint on wildlife. According to various researches, the various random changes in the wildlife have one thing in common and that is a warmer world.
For the first time, scientists have found a direct relationship between global warming and the evolution of contemporary wildlife. This is what a research team had to say about it, “We think we know a lot about how animals might respond to global warming, but we really have very little idea about their actual genetic response to environmental change”. Global warming is one of the gravest threats facing wildlife today. Plants and animals around the world are in real danger of falling victim because their habitat is changing too rapidly for them to cope up.
There is no remaining scientific debate that humans are causing global warming and it is past time we do something about it but some still believe that global warming is not the key to the receding wildlife on the planet. Computer models predict that continued global warming could have catastrophic effects and changes in temperature could devastate wildlife. According to some, there are no long-term seasonal trends. Instead, year to year and decade to decade variability is most evident. In no season do recent temperatures appear unusual compared with observed temperature history? There is no evidence of climate change. Several studies have shown that during the several decades, the population in major U.S cities has grown better adapted and thus less sensitive, to the effect of excessive heat events.
Warming during the last 50 years is causing glaciers to melt and recede. It appears that the rise of sea level and inundation of shallow coastal wetlands is inevitable. Ten years or so ago, the divergence between satellite and ground-based measurements of temperature was a big problem – the ground-based measurements showed warming in line with climate models but the satellites showed a cooling trend. The combination of new data and improved calibration has gradually resolved the discrepancy in favor of the ground-based measurements and the climate models. Finally, the evidence has come up to support those who do not believe that global warming is negatively affecting the wildlife, that with a handful of exceptions, others who do not believe in the harms of global warming, are not as fearless of seekers of scientific truth as they claim to be, but ideological partisans and paid advocates presenting dishonest arguments for a predetermined party line conclusion.
Whether global warming is the cause of the recession of the wildlife or not, the effects caused by it all around the globe can certainly not be called positive. If the population of the globe does not unite now to stop this slow poison, it might get too late.
