Why is the earth slowly but surely getting warmer?
This is a question I have been thinking about recently seeing as we (in 🇳🇴)have lesser snow by the minute,and more rain pouring down every year! Something is clearly not right! This and more questions will be answered in this post! But mind you this is a large topic and will take a lot of time to understand properly !
First things first :
I an effort to learn more about the problems that are facing us I am trying to educate myself more on the subject of global warming.Why the sudden interests? Well for the simple reason that I have noticed over the last few years in particular how every winter feels shorter and shorter and plus the lack of snow worries me❄️
Why is global warming happening?
The climate is changing because systems on, and beyond the earth are changing.
The earth has always experienced changes in climate, but they have occurred as a consequence of natural changes like changes in the angle of the earth’s axis, or in the earth’s orbit round the sun, and variations in solar radiation. Natural changes are still taking place, and these are changes not made by humans.
The reason for this is complex feedback loops between the atmosphere, the oceans and the ice. It is therefore difficult to predict how quickly the changes will take place, but they have so far occurred more rapidly than most scientists expected.
Measurements reveal that the temperature over land areas has risen more than in the sea, and that this has been greatest in winter. Climate models which calculate the future trend in the climate show that temperatures will continue to rise, and before the turn of the century the increase will be about 3-5 °C over land and up to 7 °C over the oceans.
Winter temperatures are expected to rise even more, and this can be a huge problem in the future.
Observations suggest that precipitation in arctic regions has increased by almost 10 %, but lack of data and difficulties with the measurements make the results somewhat uncertain. The total annual precipitation is expected to increase by around 20 % by the end of this century. Most of this will fall as rain in summer, but the greatest increase will occur in winter, when up to 30 % more precipitation is expected.
Mankind now has technology that can change the climate, the environment and nature. Unfortunately, we still know too little about how and why we bring about these changes, and for some parts of the Arctic we know little about their state before we began to change them.
Research is needed to learn more about what has happened, what is happening and what will happen. Scientists gather data, and perform detailed studies of problems such as the natural trend in the climate since the last Ice Age and the distribution of sea ice in the polar regions. This knowledge assists politicians and other decision makers to reach correct and important decisions. It helps us to take care of and preserve nature that is vulnerable to sudden changes resulting from our technological progresses!
I for one hope that some day we can reverse back all the bad choices so that we have winters filled with snow,and not ☔️ or a few snow days maybe in January!
More on this topic coming up next week!
