Why a few degrees temperature rise matters?
Wrong!!
Look at it this way: During the Earth’s last ice age, the Earth was only about 6.7–10°F (4–6°C) cooler than it is today. Although it may not seem like much, these few degrees were responsible for blanketing huge areas of the Earth in thick layers of ice. It had such an impact on ecosystems that some animal species became extinct.
Thus, although a few degrees may seem trivial, the Earth’s climate is so sensitive that those few degrees can make a big difference. Scientists have already proven that temperatures are rising, making it something people cannot ignore now or in the future.
The more people learn about the effects of global warming and how it can affect ecosystems worldwide, the more that can and must be done to slow down the changes. Society has progressed to a point where avoiding global warming is no longer an option, but learning how to slow it down, adapt, and have each person learn to do their part are important pieces of any solution.
Today is the time for action, and people can make a difference. It is key to understand the following:
- Global warming cannot be completely avoided any longer— it is already under way.
- The Northern Hemisphere is expected to warm up more than the Southern Hemisphere.
- Global warming is already having an impact on ecosystems, such as communities, forests, sea ice, permafrost, and wildlife habitats.
- Although some change in climate is normal, humans are causing the bulk of recent changes and rises in temperatures.
- It is humans who are adding greenhouse gases at accelerated rates to the atmosphere, and there are measures that can be taken to help reduce climate change, such as using renewable energy and conserving precious natural resources and other environmentally friendly decisions.

Updates on Global Warming:
U.S. and British meteorologists have reported that the earth’s troposphere is also heating up along with the surface due to global warming. Troposphere is the very first layer of atmosphere above the surface where weather related events occur. The revealing has been done based on data of troposphere temperature recording for the last four decades.
