Maple syrup producers see climate change as a threat to industry's future

Mills helped call attention to the state's annual celebration of pure Maine maple syrup and the Mainers who produce it. After violent windstorms recently swept through southern Ontario and Quebec, uprooting trees and leaving a trail of damage across a vast territory, Renaud's thoughts went right to his sugar maples in Lanark Highlands, Ont., where storms once considered rogue now seem more frequent.Worsening storms aren't the only changes Renaud sees.

"Trees get stressed and then they are more susceptible to pests and pathogens," said Joshua Rapp, an associate at Harvard University's school of forestry. Each year between late February and early May, maple syrup producers rely on the delicate freeze-thaw cycles of spring. When nighttime temperatures drop below zero, the maple tree contracts and sap rushes up from the roots into its branches. When temperatures rise during the day, the tree's wood expands, putting pressure on the branches and forcing the sap back down the trunk and into the taps.

The effects of changing temperatures are felt unequally. Warmer temperatures could benefit northern parts of Ontario and Quebec, which could see up to 40 litres more sap per tap each year. The industry says keeping up with global syrup demand will require tapping 120 million more trees by 2080. That rise in consumption will add to the carbon levels in the atmosphere due to the wood or other fossil fuels burned to boil the sap.

good， it too sweet for people

😂😂😂😂

Good.. Took them 60 years and 40 000 scientist to understand... Slow like that..even a turtoise do better..

It’s like all you people think co2 and nice weather is good for trees… suckers

The sap will stop flowing? Doubtful…

Oh know, better start hiking up the prices at Millers Meats !😂 winnipeg

Here comes the government money to bail them out .

Climate change threatening maple syrup industry, producers say - National | Globalnews.caSyrup producers are recording declining yields due to rising global temperatures, which are leading to more invasive pests, sap that is less sugary and shorter harvesting periods. You mean the weather hasn't been great last few years for producing syrup. Not climate change. Gas prices are one thing, mess with our maple syrup and it could lead to a civil war!
