I regularly write op-eds, often about climate change and the Arctic, in the Norwegian newspaper Klassekampen. These columns are – besides English – also available in the original Norwegian version and in Dutch. English translations of these columns are added irregularly.

Norway's continued investment in the oil industry could mean economic suicide.
Last Tuesday, the International Energy Agency (IEA) released a bombshell of a report. It advocated an immediate stop on the exploration of new oil and gas fields to limit global warming to 1.5 degrees. In addition, the IEA projected an explosive growth in solar and wind energy, which means ... Continue reading →

All Norwegian political parties say they want to solve the climate crisis. Do they mean that?
Does it matter who Norway votes for when it comes to climate? Norwegian politicians, from left to right, promise a green future in their party programs – in which the ideological differences seem to have disappeared. Recently, the greens of Mdg supported more research into modern forms of ... Continue reading →

Snow on the Acropolis does not herald a new Ice Age.
It's like clockwork: as soon as it freezes somewhere – like -27.5 degrees Celsius in Hemsedal, Norway recently – the climate skeptics wake up from their hibernation. In this case, it was none other than the vice-speaker of parliament, Morten Wold, who in a Facebook post put the strong ... Continue reading →

How does quick clay cause landslides? And can climate change make this worse?
On the night of December 30, the ground under a neighborhood in Gjerdrum, Norway suddenly became unstable. People, animals and houses were dragged hundreds of meters away, and ten people were killed. This terrible disaster raises many questions. What was the cause of the landslide? Why were ... Continue reading →

Could Joe Biden's election signal a turnaround in climate politics?
Last Wednesday, while the world was anxiously following the results of the US elections, those same United States quietly left the Paris Agreement. It is one of the many messes after four years of Trump that Joe Biden will have to clean up. As if the pandemic, social inequality and intense ... Continue reading →

Less coal and lower CO2 emissions: A glimpse that change is on the way?
2020 is a horrible year in which nothing seems to be going right in the world. The pandemic, Donald Trump's chaos and on top of all that: climate change that's getting worse and worse. Last summer was the warmest ever recorded on our side of the planet. Australia, California and Siberia have ... Continue reading →

Is the Greenland ice sheet lost forever – or can we still turn the tide?
While a temperature of 54.4 °C was recorded in Death Valley – possibly a new world record – news surfaced that Greenland's ice sheet has melted to a point of no return, even if we manage to halt climate change. The study appeared on CNN on August 14th, among others. The Greenland ice ... Continue reading →

Higher emissions lead to more warming, which in turn leads to higher emissions
Not satisfied with the summer weather? Try a holiday in Siberia! The remote arctic village of Verkhoyansk was – until now – famous for being the coldest inhabited place in the world because they recorded 67.8 degrees below zero once. But that was 128 years ago. Last month, temperatures ... Continue reading →

Does Norway need wind energy to enable a fossil-free future?
It must have been a beautiful day in spring, now 15 years ago. I drove through the rolling countryside in central Germany, on my way to the forest where I did fieldwork for my Master's thesis. I saw hills covered with meadows, with a row of windmills adorning almost every top. Spinning ... Continue reading →

Norway's debate about arctic oil exploration is farcical.
While oil prices in the USA dropped below zero, the Norwegian government clung to the fossil fuel-driven economy. Airline companies that fly nowhere and oil companies that cannot get rid of their oil will receive tens of billions of dollars in tax benefits and favorable loans – without any ... Continue reading →

It’s not a given that things will be different this time around.
While half the world is sitting at home waiting for the pandemic to pass, the polluting influence of humans has entered a decline.

Isn't it better to let the earth warm up a bit and pay for the inconvenience?
The recent forest fires in Australia, which were devastating to both humans and animals, came after a record-breaking drought and a summer with unprecedented high temperatures. Still, Australia's Prime Minister, Scott Morrison, denies that reducing Australia's emissions could have any impact ... Continue reading →

We cannot save the climate by planting trees on Greenland.
At the failed climate summit in Madrid it became, once again, abundantly clear that international climate policy is completely dysfunctional. After 25 climate summits, global emissions are still rising, while they need to be reduced by at least 7% per year in order to avoid global warming of ... Continue reading →

Apparently, there's no good news on climate without cooking the books.
The Norwegian governing parties Høyre and Venstre recently had a climate celebration on social media: Greenhouse gas emissions decreased for the third consecutive year and have not been this low since 1995. Venstre tweeted a chart where emissions appeared to be cut in half, and Høyre ... Continue reading →

A better planet is not only defined by lower CO2 emissions.
Imagine that by tomorrow, fossil fuel emissions have suddenly been reduced to zero. That, in some magical way, every car in the world is electric, we only generate electricity with sun, wind and water, and that chimneys of factories neatly capture CO2 and store it underground. If so, has the ... Continue reading →

Local climate policy is an important part of the solution to the climate crisis.

Right-wing parties have not always been bad for the environment.

From their holiday destinations – one was bobbing in a rubber boat at a campsite in Tønsberg, and the ... Continue reading →

It is too early to throw in the towel and wait for the end of the world.
"Are you a climate optimist or a climate pessimist?", I was asked, just after I had given a lecture of an hour about the threat of climate change on the polar region.

Collective action against the climate crisis is badly needed. Time for the green vests?
Save the climate, have fewer children! I regularly come across this advice, in the newspaper or on social media, often in a nicely designed graph.

Biodiversity is essential – not a luxury or a left-wing hobby.
Pando, the forest of one tree, is not doing well. And it's not because of global warming for a change.

To choose polluting aircraft over the train is incomprehensible.
The fight against climate change can be complex, but some decisions are simple. Like not building a third runway at Gardermoen, the airport of Oslo.
