What is thin, green and prosperity thanks to climate change?

If you guess the algae, you are right.

New research published in Communications Earth & Environment indicates that the growth of algae is increasing in Canada Lakes – and even those remote – climate change is the main perpetrator.

A team led by researchers at McChel University in Montreal and Université Laval analyzed the sediments’ nuclei taken from 80 lakes across the country and found that algae has been increasing mostly since the mid -nineteenth century.

For the main author Hamid Garanari, the most interesting discoveries were an increase in the rate of algae growth: since the 1960s, seven times increased.

“This was very surprising to us and when we compared our data with other historical records, we discovered that high temperature is a major factor,” said Gabari.

Aside from climate change, nitrogen and phosphorous can also contribute to algae growth when they are carried in waterways through surface flow of animal fertilizer, chemical fertilizers, storm water and wastewater.

Algae, along with bacteria and plant plankton, are necessary for the aqueous food network. But a lot of algae can be a bad thing.

Recently published Study of the counterparts I looked at algae growth in general and did not analyze flowering.

While some lakes see some algae as part of its cycle, Granari said that anxiety is what will happen if the increase in algae leads to growth outside what is normal.

“This is where the problem begins,” he said. “We don’t know at the present time what this threshold is, but we know that the levels of chlorophyll or the increasing algae in the lakes may lead to several problems.”

Gharbari said that the growth of excess algae can harm water life and even human health – reduce water quality, exhaust oxygen in the water and create flowers that can release dangerous toxins, as residents Along the beaches of Lake Erie You know everything well.

“There is a risk to water life,” said Daril McGDRIRIC, head of water quality control and monitoring of the great lakes of the environment and climate change.

“The study is in line with what we see and (we do not doubt that) the effects of warming,” said McGDREC.

It can help global and local work

“Her team noted directly that when the weather is warmer, they see more algae on the lakes.” Her team noted that when the weather is warmer, they see more algae on the lakes.

She said that her ready -made meals from research is that treating algae growth cannot only depend on local work.

“We have already known that we need to change locally – like agricultural practices and also, for example, we need a less paved and water -resistant surface in cities.”

“But what the study shows is that we also need global policies to reduce climate change.”

Gharabari agreed, but added that individual options still help reduce algae growth.

“Simple verbs such as reducing fertilizers … or eliminating home chemicals properly, these simple verbs can help in lakes,” he said.
