There are just certain topics that I wish I knew more about, and the environment/global warming are one of those topics.

A few thoughts hit me over the Christmas (In Norway) “why is there so little snow”, and why is there 3 degrees above cero in the middle of December ?

Something is terrible wrong, and so the question is “how can we make small changes” from day-to-day that can make a huge difference in the years to come? Changes that can maybe insure snow for future generations?

That is what this posting series will be all about. Making small changes, and teaching myself more about the topic in the process!

The goal

 

Well I am glad you asked me that question, and so here comes the answer as I after much reading understand it.

Global warming:


Global warming is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.


Global warming can be best understood as the gradual heating of Earth’s surface, oceans and atmosphere. Since the late 1800s scientists have documented the rise in average temperatures worldwide. Earth’s average temperature has risen by 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past century, according to the Environmental Protection Agency (EPA). Scientists say the temperatures  are projected to rise another 2 to 11.5 degrees F (1.133 to 6.42 degrees C) over the next 100 years. Is that a scary thought to more people than me????

Most of the leading scientific organizations in the world acknowledge the existence of global warming as a fact, according to a NASA report. Furthermore, 97 percent of climate scientists agree that the rate of global warming trends the planet is now experiencing is not a natural occurrence, but is primarily the result of human activity. That consensus was made clear in a major climate report released Sept. 27, 2013, by the Intergovernmental Panel on Climate Change (IPCC). In that report, climate scientists indicated they are more certain than ever of the link between human activities,and global warming.

 

 

The greenhouse effect:

Global warming begins with the greenhouse effect, which is caused by the interaction between the Earth’s atmosphere and incoming radiation from the sun. The basic physics of the greenhouse effect were figured out more than a hundred years ago by a smart guy using only pencil and paper Svante Arrhenius in 1896 was far ahead of his time.

Solar radiation passes through the atmosphere to the surface of Earth, where it is absorbed and then radiated upward as heat. Gases in Earth’s atmosphere absorb about 90 percent of this heat and radiate it back to the surface, which is warmed to a life-supporting average of 59 F (15 C). This very helpful process is called the greenhouse effect.

Personally I find the topic of global warming/the greenhouse effect, and how it affects us deeply terrifying but interesting at the same time. Once you start reading on the topic you find how little you really know, and how much you truly ought to understand plus read up on when it comes to this topic. The topic is something we hear so much about, and try to discuss without really knowing what we talk about. When we choose to have an opinion on such a large, and well researched topic. We should do our very own research, and read multiple sources at the same time. That way you can make up your own mind, and have as informed opinion as possible. We should be more critical of what the media prints, but that is an entirely other topic 🙂

The topic of global warming, and greenhouse gasses is something I will be writing a whole lot more on in the future!

Here are eleven facts about global warming that might surprise you, and even educate you a bit. I for one find this whole situation pretty scary!

  1. Global warming is the increase of Earth’s average surface temperature due to greenhouse gases that collect in the atmosphere like a thickening blanket, trapping the sun’s heat and causing the planet to warm up
  2. Greenhouse gases keep heat close to the earth’s surface making it livable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal).
  3. With the start of industry in the 1700’s, humans began emitting more fossil fuels from coal, oil, and gas to run our cars, trucks, and factories. By driving a “smarter” car, you will not only save on gas, but help prevent global warming.
  4. There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years.
  5. Though Americans make up just 4 percent of the world’s population, we produce 25 percent of the carbon dioxide pollution from fossil-fuel burning — by far the largest share of any country.

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!
