The Lockdown’s Lessons for Climate Activism

Published by Wall Street Journal

For decades, climate activists have exhorted people in the wealthy West to change their personal behavior to cut carbon emissions. We have been told to drive less, to stop flying and, in general, to reduce consumption—all in the name of saving the planet from ever higher temperatures. The Covid-19 pandemic has now achieved these goals, at least temporarily. With the enormous reduction in global economic activity, it has been as if people around the world suddenly decided to heed the activists and curtail their travel and consumption.

As we begin our global climb out of the coronavirus depression, we shouldn’t start by letting bad green deals make us poorer

Published by Financial Post

After the ravages of the coronavirus pandemic, the world will be spending trillions of dollars to get us back on track. Increasingly, campaigners and influential policymakers demand this spending be tied to climate goals. IMF chairwoman Kristalina Georgieva urges “We must do everything in our power to make it a green recovery,” and U.S. Democrats, the European Commission and many other countries are pushing ”Green New Deals.” These could cost us tens of trillions of dollars, and, unfortunately, will be one of the worst ways to help us recover.

Earth Day at 50: A surprising success story

Published by The Globe and Mail

As we celebrate the 50th anniversary of Earth Day and the birth of modern environmentalism, we should pause to give each other a virtual high five for the impressive environmental progress society has accomplished during this span. We should also think about the ways we can make the next 50 years far more effective. Case in point: many people are surprised to hear that the environment is improving. A lot. This surprise grows from the unfortunate flip side of the Earth Day legacy, which too often can focus on doomsaying and alarmism, which can make us despondent and drive poor policies.

Cleaner Air for Every Household

Published by The Daily Graphic

Cooking over an open fire or with traditional stoves is widely practiced in Ghana, but these common methods carry serious risks. Emissions caused by the use of solid fuels such as wood and charcoal are one of the leading health concerns in many developing countries. Globally, over 1.6 million people died in 2017 from diseases related to poor household air quality, and in Ghana, 10,000 lives are lost to this cause annually.

Extra emissions are the dirty little secret of electric cars

Published by The Australian

If you listen to the media, a green automotive future has arrived and a tsunami of electric cars is out­selling petrol and diesel around the world, transforming the planet and solving climate change. We need a reality check. Battery-powered electric vehicles are fairly popular in urban China and California, as well as a few countries that heavily subsidise their drivers. But globally, fewer than 0.3 per cent of all cars are pure electric, and across Europe, BMW says, customers don’t want them.

We don’t have money to burn on green mania

Published by The Australian

Scenes of devastation from Australia’s fires have been heartbreaking. How do we stop this suffering? For many campaigners and politicians, the answer is clear-cut: drastic climate policies. When we examine the evidence, this simple answer falls short. Australia is the world’s most fire-prone continent. In 1900, 11 per cent of its surface burned annually. These days, 5 per cent of the country burns every year. By the end of the century, if we do not stop climate change, higher temperatures and an increase in aridity will likely mean a 0.7 percentage point increase in burnt area, an increase...

Kritikere glemmer forbløffende nok at udfordre bare én af mine pointer

Published by Berlingske

Min kronik 17. november havde tre pointer: 1) Danmarks nye 70 pct. klimareduktion i 2030 vil koste mindst 842 mia. kr. over 30 år. 2) Fordelen kan estimeres ved at bruge et studie, der hen over alle skadesmodeller og FNs fem hovedscenarier viser, at et ton CO₂ reduceret i 2030 medfører en skadesreduktion på 31 dollar. Det betyder, at Danmarks bidrag gør tre øre godt for hver krone. 3) Danmarks reduktion vil ifølge FNs klimapanels vurdering reducere den globale opvarmning med en titusindedels grad i 2100.

Mi lehet a klímaváltozás elleni harc reális útja?

Published by Index

Az emberi történelem azt mutatja, hogy az energia rendszerek átalakítása - főleg nagy gazdaságok esetében - hosszú időt, akár 50-100 évet is igénybe vesz. Az EU előtt álló 30 év nagyon kevésnek tűnik, hogy ezt a teljes változást végre lehessen hajtani és a célként kitűzött nettó nulla üvegház hatású gáz emissziót elérje a 28 tagállam. Ráadásul először fordul elő az emberiség története során, hogy a kibocsátás csökkentése a cél és nem kizárólag az, hogy javítsunk az energiarendszer hatékonyságán. A múltban ugyanis mindig az a rendszer diadalmaskodott, amely javítani tudott az egységnyi...

Empty Gestures on Climate Change

Published by Project Syndicate

Switch to energy-efficient light bulbs, wash your clothes in cold water, eat less meat, recycle more, and buy an electric car: we are being bombarded with instructions from climate campaigners, environmentalists, and the media about the everyday steps we all must take to tackle climate change. Unfortunately, these appeals trivialize the challenge of global warming and divert our attention from the huge technological and policy changes that are needed to combat it.

Hvis Mette Frederiksen var modig, ville hun gøre som New Zealand - men hun ville ikke kunne lide resultatet

Published by Berlingske

Jeg pointerede i min nylige kronik (17. november) at regeringens klimaløfte, der skal skære 70 pct. i 2030, vil koste mindst 842 milliarder kroner og reducere den globale temperaturstigning i år 2100 med en titusindedel grad.
