It is still a subject of debate whether how hot is the "acceptable" global warming that might result from greenhouse gasses build up in the planet. Now that global leaders are seeking for sterner policy to alleviate global warming, technical numbers that refer to temperature increase is also becoming a crucial point. Calculations, formula, and models are getting more and more tangled in the numbers debate.
Under the climate change parlance, global warming is the gradual increase in the air surface temperature. However, another round of urgency came to policy makers as a new study suggests that climate sensitivity is parallel with what experts previously thought. This is backed by a conclusion that as factors of climate change kicks in, the sensitivity and warming rate escalates as well.
There is not much difference in the current global warming benchmark of 2.9 degrees Celsius. Comparably, some models suggest that the danger zone for global warming could be just a decimal higher. At any rate, climate change is apparently picking up its pace compared to the pre-industrialization period, according to the Science Daily.
Meanwhile, oceanography and atmospheric science professor Kyle Armour of the University of Washington said that the data is alarming. When the climate adjustment mechanism of the earth is taken alongside the sensitivity model, they appear to be identical, Armour wrote in the Nature Climate Change. Meaning, recent observations and previous theories about global warming is spot on correct all along.
Theoretically, the earth is going to experience an increase of 3 degrees Celsius or probably as high as 6 due to the build-up of carbon dioxide in the atmosphere. This is imminent if the CO2 volume breached twice that of the pre-industrialization period. Currently, it gives no comfort that the earth is already at 1.4 times level - routing to global warming. To make the matter worse, scientists believe that the earth needs thousands of years to fully adjust to this new atmospheric composition or any climatic shift.
