Link builds between weather extremes and warming

Extreme rainfall, heat waves and increased pollen-induced allergies are to be expected as climate change unfolds

Reuters / Extreme weather events over the past decade have increased and were “very likely” caused by man-made global warming, a study in the journal Nature Climate Change said March 25. Scientists at Germany’s Potsdam Institute for Climate Research used physics, statistical analysis and computer simulations to link extreme rainfall and heat waves to global

How ice loss influences the jet stream

I’ve spent a fair bit of time discussing the record warm weather we experienced in March over the last few weeks. We’ve looked at just what led to this remarkable weather and we discussed just how intense it really was. The fact that we saw temperatures that were between three and four standard deviations above


Warm, then cooling trend

It looks like this forecast period will start off a little quieter than last week. After seeing several lows pass through our region over the last week bringing more clouds than sun, plenty of showers, rain and even a little snow, it looks as if a ridge of high pressure will build in during this

Texas drought losses pegged at $7.6 billion

college station, texas / Last year’s drought in Texas cost farmers and ranchers a record $7.62 billion, a newly released study says. “The $7.62-billion mark for 2011 is more than $3.5 billion higher than the 2006 drought loss estimates, which previously was the costliest drought on record,” said David Anderson, a livestock economist with Texas


Seaway opens, expects strong year

The St. Lawrence Seaway is open and officials predict cargo shipments will rise by about three per cent to 38.6 million tonnes this year. Coal from Montana is expected to be a bright spot, but increased grain movement is expected following a $30-million investment by Parrish and Heimbecker in its grain-handling facility at Hamilton, the

U.S. heat wave breaks records

Reuters / An “unprecedented” March heat wave in much of the continental United States has set or tied more than 7,000 high temperature records, and signals a warming climate, health and weather experts said on Friday. While natural climate variability plays a major role, it is the addition of human-spurred climate change that makes this particular


U.S. flood risk low, but droughts, wildfires could continue

Reuters / No area of the United States faces a high risk of major flooding this spring for the first time in four years, but continuing drought across the southern and western parts of the country could lead to wildfires, U.S. government forecasters said March 15. The National Oceanic and Atmospheric Administration said in its

Mexicans see current drought as sign of drier years to come

Reuters / Authorities fear a severe drought in Mexico is just a foretaste of a drier future. As water tankers race across northern Mexico to reach far-flung towns, and crops wither in the fields, the government has allotted US$2.7 billion in emergency aid to confront the country’s worst-ever drought, which has caused $1.2 billion in


Spring heat wave comes to an end

What has been dubbed “summer in March 2012” has now finally come to an end. This rare March heat wave stretched from southeastern Saskatchewan across southern Canada all the way to the eastern seaboard and southward into most of the eastern United States. Last week I explained what conditions came together to bring us this

Well-above-average temperatures to continue

After a brief period of average temperatures last weekend, which really felt cold, it looks like we’ll be returning to much-above-average temperatures during this forecast period. While it looks like temperatures will be warm, it also looks like it could be fairly wet, with plenty of potential storm systems poised to affect our region. The
