Global warming is no more a joke. The recent findings are clearly manifesting that planet is getting hotter day by day. It has been proved scientifically in many findings that global warming is a certainty due to which several events are taking place such as melting ice, extreme weather conditions, warming oceans, etc. One of the recent findings is predicting that a warmer world will have less snow and ice. The study is suggesting that areas having year-round ice and snow will start melting due to global warming. It is further suggested that glacier melts faster at the bottom, shortening the glacier and reducing its mass. The melted water will eventually result in increasing the sea level.
The recent study conducted by Dominic Winski and his colleagues suggests that the amount of water melt currently is 60 times greater than it was prior to 1850. The team extracted ice cores to conduct research from the glaciers on Mt. Hunter, in Alaska. While conducting their research, they found that the summertime temperature changes on Mt. Hunter are almost 2°C per century (about 3.5°F) which are actually twice as compared to global temperature.
Their climate models are clearly manifesting that temperatures on these northern mountains are rising faster than the globe. The reason for this behavior is that when snow begins to melt, it exposes dark soil, which absorbs more sunlight, leading to further warming. The researchers call this a feedback loop. The team suggests that other feedbacks also play their part in accelerated melting like changes to vertical temperatures in the air, changes to clouds, and changes to atmospheric currents. The measurements are confirming the predictions.
The authors find that top layer of snow and ice melt during the summer. Due to this, the liquid water permeates the ice beneath it and refreezes, creating a more solid ice layer than before. The melting snow causes the formation of solid ice bands. Measuring the number and thickness of these bands through time enables the researchers to give information about how warm the summer temperatures are. Lead author, Dominic Winski, summarize his findings and claims that their study found that the frequency of melting events increased by 57-fold from the 1650–1850 time period compared with 1980–2011.
The published, as well as ongoing researches, are clearly manifesting that global warming and climate change is a reality. Global Warming is causing a tremendous impact on the biodiversity of the planet. The melting ice caps, warming oceans, rising sea levels and extreme weather conditions are the visible effect of global warming. Time has come for the global community to think how to combat this problem.
