Climate change has allowed trees to grow longer and absorb more CO2

(ORDO NEWS) — The early arrival of spring and warmer temperatures have extended the growing season for trees by about a month, during which they grow and develop.

This means that plants have more time to actively absorb CO2, but heat stress can have a negative impact on the flora, according to scientists at Ohio State University in the United States.

American researchers have found that over the past 100 years in Ohio, hardwoods have received an extra month of the year to grow due to the warming climate.

According to the lead author of the study, Professor Kellen Kalinger-Joak, the leaves on the trees lasted about 15% longer than they did a century ago.

“A whole month of growing season extension is huge when we are talking about a fairly short period of time when these changes need to be expressed,” the BBC quoted the scientist as saying.

The professor noted that different species reacted to higher temperatures in different ways. Some trees did not shed their leaves for longer, others gave buds earlier.

Scientists have not yet studied the effects of a longer growing season, but they suggest that it will allow plants to absorb carbon dioxide from the atmosphere for longer.

At the same time, the researchers warn that heat stress can affect the ability of vegetation to absorb CO2.
