Scare of the day: Rising use of nitrogen fertilisers could jeopardise global climate goals

That’s a large chunk of the global food supply in the dock then, according to IPCC-based ‘greenhouse’ climate theories that perform badly in climate models, leading to endless over-prediction of global warming.

The growing use of nitrogen fertilisers in world food production could put ambitious climate targets out of reach, as it leads to rising levels of nitrous oxide (N2O) in the atmosphere, a new University of Oslo study shows.

Nitrous oxide (N2O) is a highly potent greenhouse gas, and its impact on global warming is 300 times larger than that of carbon dioxide (CO2). Once emitted, N2O remains in the atmosphere for more than 100 years. What’s more – it also depletes the ozone layer.

If left unabated, the emissions resulting from the growing use of nitrogen fertilisers will require bigger reductions in CO2 emissions to reach the goal of the Paris Agreement to keep the global temperature rise this century well below 2°C above pre-industrial levels, according to the study.

Study puts ‘agriculturally-driven climate change’ on the alarmist menu

Get ready to be told what the new rules of food consumption should be, according to climate-obsessed researchers. That seems to be the message being pushed here. All based on the assertion that minor trace gases in the atmosphere are going to dictate what happens to the weather, of course.

Reducing fossil fuel use is essential to stopping climate change, but that goal will remain out of reach unless global agriculture and eating habits are also transformed, according to new research from the University of Minnesota and University of Oxford.

A paper published Thursday in the journal Science reveals that emissions from global food production alone could lead to a global temperature increase of more than 1.5°C by mid-century and of nearly 2°C by the end of the century, even if emissions from fossil fuels were to end immediately, reports Phys.org.

The study also identifies the need for large and rapid improvements in farming practices, as well as changes in what we eat and in how much food we waste, to help achieve the Paris Agreement’s goal of limiting global temperature increases to 1.5°C or 2°C.

Solar linked 2C downturn in Canadian prairie temperatures affecting grain yields.

H/t to Electroverse for the heads up on this paper detailing the effect of reduced solar activity and cyclic oceanic oscillations on Canadian agriculture. Let’s hope the policymakers see through the warming dogma in time.

Is Diminishing Solar Activity Detrimental to Canadian Prairie Agriculture?

Ray Garnett¹*, Madhav Khandekar² and Rupinder Kaur³

Abstract: During the grain growing months of May-July, the mean temperature on the Canadian prairies has cooled down by 2ºC in the last 30 years. The cooling appears to be most certainly linked to diminishing solar activity as the Sun approaches a Grand Solar Minimum in the next decade or so. This cooling has led to a reduction in Growing Degree Days (GDDs) and has also impacted the precipitation pattern. The GDDs in conjunction with mean temperature and precipitation are important parameters for the growth of various grains (wheat, barley, canola etc.) on the prairies.
