Climate change: Positive impact on rice, tea in Northeast

Kolkata: A scientist claimed that climate change was going to “positively” impact rice and tea crops in the Northeast.

According to Chandan Mahanta of the IIT-Guwahati, a modelling study carried out by the institute showed in the next 15 years (till 2030), rice and tea can actually have an advantage from climate change.

“Climate change is going to positively impact rice and tea in at least coming 15 years in the northeast. We have modelled that,” Mahanta said here at the South Asia Water Dialogue, adding that scientists looked at climate data, such as temperature, humidity and precipitation in the region to study the changes on the two important crops.

Explaining the variation, he said: “Sometimes it’s not just the temperature alone but also the rate of change of temperature or the rate of change of precipitation so it is not always very simple to say.”

In addition, the difference in growing times also has an influence.

“Tea is grown at three different times. Even rice is grown at different times. Maybe one particular rice variety may be less affected, others may be more affected,” said Mahanta, a professor of the department of civil engineering.

The last 10 years were the hottest decade ever measured on Earth, last year was the second warmest ever and NASA says “you haven’t seen anything yet.”

The National Oceanic and Atmospheric Administration said Wednesday that the average global temperature in the 2010s was 14.7 degrees Celsius, with eight of the 10 hottest years ever recorded.

Parts of Africa, Asia, Australia, Europe and South America had record-high temperatures in 2019. Alaska’s average temperature was above freezing for the first time in recorded history.

Many climate scientists who have seen the study said there was no other explanation for the record-breaking warming than human activity.

“This is going to be part of what we see every year until we stabilize greenhouse gases,” said Gavin Schmidt, head of NASA’s Goddard Institute for Space Studies. “We crossed over into more than 2 degrees Fahrenheit warming territory in 2015 and we are unlikely to go back. This shows that what’s happening is persistent, not a fluke due to some weather phenomenon.”

Experts say natural causes of a warmer atmosphere, including more heat from the sun and climate variations, are not big enough to explain the long-term temperature rise.

For those who still question global warming, the scientists say all one has to do is look at melting ice sheets, more powerful storms, floods in some parts of the world and drought in others as clear evidence. (VOA)
