Issued: Monday, February 23, 2009 Covering: February 25 –March 4

Last week we talked about arctic high pressure dominating the weather and it looks like the same thing will happen during this forecast period, at least during the first half. It is currently looking like a strong area of arctic high pressure will build southwards over Western Canada during this week. This region of high

Natural Trend Or Global Warming?

During the win-ter months the one thing I probably hear the most in regard to global warming and climate change is “how can it be so cold if we are experiencing global warming?” or “we just broke a record low, where’s global warming now?” At first glance these comments kind of make sense. After all,


China declares emergency as drought bites

China has declared an emergency over a drought which could damage the important wheat crop, threatening further hardship for farmers amid slumping economic growth. The dry winter gripping parts of central and northern China sent Zhengzhou wheat futures up five per cent last week but physical prices have not moved, with most investors confident the

La Nina seen gradually weakening in 2009

The La Nina weather anomaly will persist into the spring of 2009 but should gradually weaken during that period, the U. S. Climate Prediction Center said on Feb. 5. In a monthly update, the CPC said “a majority of the model forecasts… indicate a gradual weakening of La Nina through February-April 2009, with an eventual


General atmospheric circulation

After the last couple of weather school lessons on wind, we now have a basic understanding of what drives our winds. With this knowledge we are now ready to take this information and start piecing together the bigger picture of global winds, or what is referred to as general atmospheric circulation. We now know that



Burned plants may store more carbon in soil

An ancient technique of plowing charred plants into the ground to revive soil may also trap greenhouse gases for thousands of years and forestall global warming, scientists said Dec. 5. Heating plants such as farm waste or wood in airtight conditions produces a high-carbon substance called biochar, which can store the greenhouse gas carbon dioxide

La Nina could ease Australian drought

Australia’s drought-hit farmlands may see vital summer rains from a La Nina system that could develop next year, bringing relief after a year of sweltering temperatures above the global average, scientists said on Wednesday. Australia’s Bureau of Meteorology said farms in the wheat belt of southern Queensland and northern New South Wales states had a


Heavy rain threatens Australia’s wheat crop quality

Australia’s wheat growers, reeling from years of drought, now face a new problem, with heavy rainfall provoking concern about the quality of the 2008-09 crop. The 2008-09 wheat harvest now underway has been disrupted by downpours in some key crop-growing regions in eastern parts of the country, including the northwest of New South Wales state

Whole-systems analysis needed

Laura Rance’s column “Publicity stunt or junk science?” in the Oct. 30 Manitoba Co-operator raises a point about catchy headlines versus the central message. The National Centre for Livestock and the Environment (NCLE) is a team of research scientists dedicated to strengthening the environmental sustainability of animal production systems. Through sound and thorough scientific investigations,
