Climate conditions on Earth depend on cycles

Simplified schematic of the global carbon cycle, IPCC WG1AR5, 2013

Climate conditions on Earth depend on cycles. These cycles are a gift from Nature. They provide ecosystem services of central importance for a healthy planet and our lives. Greenhouse gas emissions caused by human activity are changing natural cycles and disturbing ecosystems dramatically.

Take, for example, the carbon cycle. Carbon is an abundant element on our planet. It is present in rocks, soils, the oceans, and the atmosphere. Slow and fast carbon cycles operate to recycle carbon continuously and balance carbon content in these different carbon reservoirs. This involves biochemical reactions, photosynthesis, and volcanic eruptions.

We do not want all…

— education and health are good places to start

We are living through an era without precedent. Truly, we have had technological revolutions before. Only this time, we are moving faster, and the scope of the societal transformations involved is far more comprehensive. This is the digital revolution, and you are part of it!

We are not talking about changing or improving the way we produce things only. With digital technology, we can pull together information and knowledge from different sources and create new knowledge. What comes out of this process has the power to change all spheres of life on our planet. …

Health Day highlights equality

Today is World Health Day. It is also the anniversary of WHO, the World Health Organization. After living a year with a COVID pandemic, this day has gotten a special connotation. What comes to mind?

This could be the worst public health crisis of modern times. At least it will be for some generations. Who could imagine the world would come to halt — not one day, not one week, but over a year? And, we have not yet seen the end of it…

On the positive side, who would imagine we could create a vaccine in one year? This…

They are the symbol of a sustainable life

One of the best things about this time of the year in the Northern Hemisphere is the arrival of spring. It means going from grey to green; from a life in black and white to life in colors.

If you are an attentive observer of nature or if you have a garden, this is the time to study the power of life. You look carefully but miss the sprouts. A minute later, they are there as if by magic.

You watch them grow day after day. Suddenly, you drop your guard, a drizzle comes and you turn away for a…

Reflections after reading Robert Greene

I have recently read Greene’s book — The Laws of Human Nature. The book has been in evidence for some time and there are plenty of interviews with the author on the internet. They give you a feeling for the author’s perspective and the idea behind the book.

There are also different reviews of the book around. One reviewer disliked the book because it does not give you the answers you might expect. That caught my attention. Contrary to this reviewer, I usually dislike books that will give me full answers to profound questions. …

Earth Hour is a global movement organized by WWF to increase awareness and motivate climate action. On the 27th of March, it is time for Earth Hour again. People across the globe turn off the lights for one hour to signal their concern about the planet and to push for change.

The urgency for strong climate policies cannot be overemphasized. Many decisions and investments made today will affect our future for decades to come. Therefore, it is important to make sure we are going in the right direction, and that investments go to low-carbon solutions.

Where to Look If We Want to Succeed

Oil has powered the modern industry for more than 150 years. Today, it is widely accepted that a low-emissions future entails breaking global dependence on oil. Does this mean we are approaching the end of the oil-era? Can we stop pumping oil by the middle of this century?

In the 1970s, oil price shocks revealed oil dependency for energy and curtailed global economic growth. Many countries put in place measures to improve energy efficiency and develop clean technologies. Where are we half a century later?

We have a global agreement to mitigate climate change, and we are moving towards larger…

How Can You Enhance Its Value in Your Life?

We always hear about the value of curiosity. If you have it, it supposedly guides you to discoveries, enhances your memory, and boosts your performance. Research has confirmed the role of curiosity in forging a rich and interesting life.

In science and arts, curiosity is an important drive. Having supervised many Ph.D. and post-doc researchers, I can only endorse the fact that curiosity is not only a great quality for a researcher to have but one that distinguishes the research results.

Curiosity takes artists into new roads of experimentation, as they search for new forms of expression, new types of…

The 22nd March is Water Day. It gives us a good reason to pause and reflect on the use of water. Why are we running out of one of the most abundant resources we have on Earth? What are we doing to guarantee that people can exercise their right to clean water?

Humans, plants, and animals need water for survival. Life on Earth, as we know it, would not be possible without water. In any eco-system, water cycles define life and the diversity of landscapes. Water is more precious than gold!

The United Nations recognizes water as a human right

Governments, companies, researchers, and drivers are all in this race

Electric cars are gaining market shares all over the world. In Norway, the sales of electric cars surpassed the sales of conventional cars in 2020.

Many choose electric cars because they are a better environmental choice. Others dislike electric cars because they provide a different driving experience compared to conventional cars.

While many people speak enthusiastically about electric cars, others remain skeptical. Still, electric cars will probably become increasingly attractive in many countries within this decade.

Why are politicians, investors, and drivers choosing electric cars? Why are researchers so busy developing them? …
