We can reach 2°C if we *replace* polluting technology

The Intergovernmental Panel on Climate Change shows that hope is not forsaken: rigorous climate politics locally and nationally has spurred development of new technology sooner than expected. Increased pressure in the pursuit of climate protection is still required to reach the 2°C Target. Carbon Budget: Trillion tons of CO2 The report from the Intergovernmental Panel on Climate Change (IPCC) on the climate climate system launched last year has a clear message: […]

Breathe easier with renewable energy

If we want to limit air pollution and reduce greenhouse gas emissions while meeting unmet demand in developing countries, renewable electricity is a promising option, as our new research shows. By Edgar Hertwich, Thomas Gibon and Anders Arvesen, NTNU The use of fossil energy sources has made it possible for cities, population and prosperity to grow. It has also […]

What’s new in the IPCC report

After 4 years of intensive work, the fifth assessment report of climate change by the Intergovernmental Panel on Climate Change (IPCC) has finally been published. It says that it is urgent to begin reducing emissions, otherwise we will not be able to stay below the articulated limit of two degree temperature rise. Sure, but that was already the main message of the […]

I took a deep breath after a brisk climb up the soft hill near the border to Sweden. The sun peaked out under the clouds and the light was beautifully reflected by the water of Nesjøen, while reindeer was munching away on delicious blueberries a little further down the ridge. The reservoir below contrasted to the barren land on the other side, making it more tranquil and interesting at […]

Ecological tragedy, economic naiveté

The tragic extinction of species, from the black rhinoceros to plants remaining undiscovered, is unfortunately one of the hallmarks of humans on the planet. This week, the Trondheim Conference of Biodiversity celebrated its 20 year anniversary by gathering 400 scientists and international negotiators to an exchange of knowledge and ideas. The focus of this conference was on the economy and options for […]

I just returned from my weekly trip to the supermarket: in addition to Kenyan roses, Brazilian melons, Israeli oranges, Dutch tomatoes, Kiwis from New Zealand, and potatoes from Saudi Arabia (!), I have, for the first time, found minced beef from Botswana, sold for just over half the price of the Norwegian one. We have over the years become accustomed to the increasing variety and prettiness of food we find on supermarket shelves, regardless […]

Germany: Solar influence on climate in public spotlight

Surprisingly, a book co-written by a well-known former German environmental activist presents a strong revisionist story and is able to capture both headlines and spot on the best-seller list. I read the book  “The cold sun: why the climate catastrophe is not happen” by Fritz Vahrenholt and Sebastian Lüning (VL) for a coherent revisionist argument. The book was written with strong conviction and a very pervasive style. It is richly illustrated with charts displaying the […]

Extinction footprints

It is a sad result of human civilisation that we are driving other species into extinction. A new study highlights the main driving forces – rich countries’ consumption. Humans have always affected their environment. Environmental history is littered with stories of modifications of the environment to enhance the growth of fruit-bearing plants and the impact of our hunting. In the Americas, the late arrival of humans resulted in an extinction of most large game – and […]

Guarantees of origin and their misuse in carbon footprint calculations

In the development of the international standard for product carbon footprint analysis, there are now forces arguing that so-called guarantees of origin (GO) should be used to calculate the greenhouse gas emissions associated with electricity. This sound innocuous, but one should not be deceived by a misleading term! Guarantees of origin are not what they sound to be: they do not guarantee that the electricity you buy is actually from the source that it is claimed […]

Unsustainable Developments

It seems like we right now are running hard from facing the truths and some associated pain, and that in at least two instances that are striking for their similarities: the global financial crisis and climate change. Let me begin with the financial crisis. The main problem of the financial crisis is that levels of debt have become too large and cannot be repaid by the original debtors. Lenders and many politicians are now […]
