South East Asia – Around 25,000 people have been affected and thousands of homes damaged after recent flooding in Malaysia, Indonesia and Thailand. Malaysia reported that over 550mm of rain fell in Marang district of Terengganu State from 23 to 25 November. As of 27 November, the Kemaman and Tebak rivers in the state were both above danger levels. Meanwhile across the Malacca Strait from Malaysia, further heavy rain has affected parts of Sumatra Island of Indonesia, with severe flooding reported in Jambi Province in particular. In Sarolangun Regency, flooding has damaged 1,417 homes, affecting 7,085 people. Southern and central parts of Thailand also saw severe weather during this period, including thunderstorms, strong winds and heavy rain. Around 2,000 people from 268 households were affected by flash floods in Kanchanaburi, Phuket, Songkhla and Yala provinces.

Global Warming

Greenhouse Rise

The U.N. weather agency says that while global carbon emissions fell by as much as 17% globally at times during the COVID pandemic, the levels of greenhouse gasses in the atmosphere have continued to rise to even higher records this year.

“The lockdown-related fall in emissions is just a tiny blip on the long-term graph,” said World Meteorological Organization chief Petteri Taalas. “We need a sustained flattening of the curve.”

He added in a statement that such a rise in carbon dioxide levels as observed over the past four years has never been seen before, either in direct measurements from the atmosphere or in ice-core samples that reveal CO2 concentrations from up to 800,000 years ago.

Trees Lose their Leaves Earlier Due To Global Warming

Trees will start to shed their leaves earlier as the planet warms, a new study has suggested, contradicting previous assumptions that warming temperatures are delaying the onset of fall.

Every year, in a process known as senescence, the leaves of deciduous trees turn yellow, orange and red as they suspend growth and extract nutrients from foliage, before falling from the tree ahead of winter. Leaf senescence also marks the end of the period during which plants absorb carbon dioxide through photosynthesis.

Global warming has resulted in longer growing seasons — spring leaves are emerging in European trees about two weeks earlier, compared with 100 years ago, researchers said.

Increases in spring and summer productivity that come as a result of elevated carbon dioxide, temperature and light levels then actually drive trees to lose their leaves earlier, the experts found. The experts now predict by the end of the century, leaves might even fall off three to six days earlier than at present.

Wildlife

Blue Whales Return

Critically endangered blue whales, the largest creatures ever known to have existed, are returning to Britain’s sub-Antarctic island of South Georgia.

U.K. scientists say the whales appear to be growing in numbers around the island after being nearly wiped out by whaling 50 years ago. While only a single blue whale was seen there between 1998 and 2018, 58 were spotted in a survey in February of this year.

Another recent study found that humpback whales are also returning to the same waters.
