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.

Scientists: Nations Need Stronger Pledges to Curb Climate Change

Governments are moving in the right direction, but nowhere near enough, so hopefully they will be willing to take on much stronger commitments

The vast majority of national commitments in the 2015 Paris Agreement are inadequate to prevent the worst effects of global warming, scientists said on Tuesday, naming the world’s biggest greenhouse gas emitting countries as among those that must ratchet up their efforts.

“Governments are moving in the right direction, but nowhere near enough, so hopefully they will be willing to take on much stronger commitments” in next month’s United Nation’s climate summit in Spain, said Robert Watson, lead author of the report by the nonprofit Universal Ecological Fund.

The report ranked nearly 75%, or 136, of the pledges as insufficient, including ones by major carbon emitters China, the United States, and India. A dozen, by countries including Australia, Japan and Brazil, were judged only partially sufficient.

Countries at next month’s summit in Madrid will hash out some details of the international pact to curb warming. Chile withdrew as host following weeks of riots protesting inequality.

Of the 184 pledges countries made under the climate agreement, only 36 are ambitious enough to help reach the agreement’s goal of keeping global warming less than 1.5 Celsius (2.7 F) above pre-industrial levels, the report said.

Most of those 36 are by countries in the European Union.

Watson, a former chair of the U.N. Intergovernmental Panel on Climate Change, said the report could be read two ways: “You can read ‘My God it’s hopeless’, or ‘My God this is a wake up call.'”

Watson estimated that even if all nations meet their existing pledges, the world would be headed for temperature rise of between 3 and 3.5 degrees Celsius, which could lead to more extreme weather, rising sea levels and the loss of plant and animal species.

The report rated the European Union’s 28 member states as having sufficient pledges because they aim to cut emissions of greenhouse gases by at least 40% below the 1990 level by 2030.

It ranked the United States as insufficient because President Donald Trump reversed former President Barack Obama’s climate policies and yanked Washington out of the pact. The administration, which argues that Paris Agreement would cost U.S. taxpayers too much money, filed official paperwork on Monday to withdraw.

China, the world’s top emitter of greenhouse gases, and India, also came in as insufficient because their pledges focus on carbon intensity targets, which lower emissions per unit of gross domestic product, or GDP. Because those economies are growing and coal produces much of their electricity, total emissions have risen sharply even though carbon intensity levels in China and India have fallen. (VOA)
