Global soil carbon losses in response to warming

In a recent study published in Nature, 50 researchers from around the world confirm the concerns that they have had for a long time: soils will release a large amount of carbon in response to the rising air temperature.

The study is a summary of 49 empirical studies that have investigated carbon emissions from the soil in different places around the world. Although the results varied slightly from area to area, the team saw a pattern in which the carbon losses were higher in those regions that have had the largest rise in temperature so far. The largest losses of carbon were seen in the Arctic areas where the soil is warming up rapidly and is quite deep. They also saw high losses along the mid-latitude areas. The study only considered the upper layers of soil, and if the soil turns out to release carbon from the deeper permafrost layer, emissions could be even more devastating.

The researchers believe that if we continue with a “business-as-usual” scenario, the soil will release 200 billion tons of carbon dioxide by the year 2050. Even if the planet’s vegetation can reclaim some of this carbon, it will not compensate for the losses that have occurred.

Livestock on leftovers

Greenhouse gas and nitrogen emissions from agriculture in the Nordic countries could be reduced by up to 80 per cent with a diet of purely organic produce from an almost self-sufficient food system.

Editorial: Another agricultural system is possible

The current production and consumption of food in the western world is unsustainable. For example, in the EU food consumption is responsible for almost one third of the total environmental impact.

New NEC Directive in force

When fully implemented in 2030, the directive will nearly halve the negative health impacts of air pollution, such as respiratory diseases and premature death.

Big emissions from small chimneys

Domestic wood burning is a major source of air pollutant emissions – a new eco-labelled wood stove is allowed to emit 25 times more health-damaging particles than a ten-year old diesel truck.

CCS is still a failure

After decades of talking and billions of euros in investments there are no large commercial CO₂ storage facilities in Norway, Canada, the US or anywhere else in the world.

Global warming and its implications for coral reefs

At current projected levels of temperature increase it has been suggested that tropical coral reefs could be lost altogether as soon as 2050.

EU needs to shut all coal plants by 2030

The EU will need to phase out CO₂ emissions from all of its coal plants in the next 15 years if it is to meet the Paris Agreement’s long-term temperature goals, according to a new Climate Analytics report released in Brussels in February 2017.

How to get people to eat less meat

Personality, friends, religion and political instruments all have an impact on what we eat. A successful strategy to reduce meat consumption therefore needs to have a mixed approach that targets different factors simultaneously.

Stronger air quality measures needed

Air pollution remains the single largest environmental health hazard in Europe, resulting in a lower quality of life due to illnesses and nearly half a million premature deaths per year.

Cost-effective to cut ship NOx emissions

By supplementing NOx Emission Control Areas with economic instruments, ship NOx emissions can be cut faster and further.

Coal project in Croatia stopped

Croatian electricity company HEP Proizvodnja was proposing that a new 500 MW unit replace the ageing Plomin 1 plant, at the site of the existing Plomin Power Station. As a result, the Plomin Power Station capacity would have increased from 335 MW to 710 MW
