Last month was the warmest September on record for planet

Earth's surface was warmer last month than any other September on record, the European Union's Earth Observation Programme said on Wednesday. Temperatures since January surpassed those of the hottest ever calendar year in 2016.

This year has now seen three months of record warmth - January, May and September - with June and April virtually tied for first, the Copernicus Climate Change Service (C3S) reported.

"There is currently little difference between 2020 and 2016 for the year-to-date," Copernicus senior scientist Freja Vambourg said.

For the 12-month period through September, the planet was nearly 1.3 degrees Celsius above pre-industrial levels.

That is alarmingly close to the 1.5°C threshold for severe impacts detailed in a major 2018 report by the UN's climate science advisory panel, the IPCC.

The Paris Agreement to combat climate change has enjoined nations to cap global warming at "well below" 2°C, and 1.5°C if feasible.

So far, Earth has warmed on average by one degree, enough to boost the intensity of deadly heatwaves, droughts and tropical storms made more destructive by the rising seas.

Climate change driven by greenhouse gas emissions from burning fossil fuels has picked up pace in recent decades.

Nineteen of the last 20 years are the warmest since accurate readings began in the late 19th century.

Since the late 1970s, the global thermometer has crept up 0.2°C every decade, according to EU data.

Temperatures in September were "exceptionally high" over northern Siberia, which - along with much of the Arctic Circle - has seen freakishly warm weather for months.

September was brutal in the Middle East, with new high temperatures reported in Turkey, Israel and Jordan.

Parts of North Africa and Tibet were also scorching hot, while maximum daytime values reached 49°C in Los Angeles County early in the month.

Across California, five of the state's six biggest wildfires in history were still burning at the end of the month.

"September was warmer by 0.05°C than September 2019, the previous (recorded) warmest September," the Copernicus report said.

Last month's global heat record was all the more remarkable because of the regional cooling effect of a naturally occurring La Nina weather event over the tropical Pacific ocean.

Arctic sea ice, meanwhile, shrank to its second lowest extent last month, slipping below four million square kilometres for only the second time since satellite records began in 1978, said C3S.

The Arctic ice cap floats on ocean water around the North Pole, and thus does not contribute directly to sea level rise when it melts.

But it does accelerate global warming. Freshly fallen snow reflects 80 per cent of the Sun's radiative force back into space.

But when that mirror-like surface is replaced by deep blue water, about the same percentage of Earth-heating energy is absorbed instead.

Climate change has also disrupted regional weather patterns, resulting in more sunshine beating down on the Greenland ice sheet, which is melting - and shedding mass into the ocean -  quicker than at any time in the last 12,000 years, according to a study last week.

Sinopharm vaccine explained

The Sinopharm vaccine was created using techniques that have been around for decades. 

“This is an inactivated vaccine. Simply what it means is that the virus is taken, cultured and inactivated," said Dr Nawal Al Kaabi, chair of the UAE's National Covid-19 Clinical Management Committee.

"What is left is a skeleton of the virus so it looks like a virus, but it is not live."

This is then injected into the body.

"The body will recognise it and form antibodies but because it is inactive, we will need more than one dose. The body will not develop immunity with one dose," she said.

"You have to be exposed more than one time to what we call the antigen."

The vaccine should offer protection for at least months, but no one knows how long beyond that.

Dr Al Kaabi said early vaccine volunteers in China were given shots last spring and still have antibodies today.

“Since it is inactivated, it will not last forever," she said.
