Wildfires in Australia caused the strongest heating of the stratosphere in the last 30 years

British climatologists have found that the massive forest and steppe fires in Australia in 2019-2020 led to the strongest heating of the stratosphere in the last 30 years. The findings of scientists published in the journal Scientific Reports.

Wildfires in Australia caused the strongest heating of the stratosphere in the last 30 years

Global temperatures rose sharply in January 2020 to peaks not seen since the early 1990s, accompanied by an anomalously strong warming of the stratosphere. Our analysis showed that the fires in southeast Australia were responsible for this warming and warming of the stratosphere.‘, the researchers write.

Large-scale forest fires began on the east coast of Australia in mid-October 2019. The fire covered large areas in the southeast of the continent, as well as a number of areas in the south of the country. The situation improved only after heavy rains that took place in the first decade of February 2020. The fires destroyed more than 12 million hectares of forest and caused the death of approximately 3 billion animals (mammals, birds, reptiles, as well as amphibians and insects). This event was recognized as an environmental disaster.

A team of climate scientists led by Lilly Damany-Pierce, a researcher at the University of Exeter (UK), has uncovered the link between these wildfires and weather anomalies that hit the world in the first half of 2020. Scientists made this discovery while calculating the climatic consequences of the “black summer”, as this cataclysm is called in Australia.

According to climatologists, in December 2020 and January 2021, a lot of drops of sulfur aerosols, microscopic soot particles and other products of forest and steppe fires, which can both cause a cooling of the climate and increase the heating of the upper and lower layers of the air shell of the planet, entered the Earth’s atmosphere.

Guided by this idea, the scientists prepared a detailed computer model that helped them calculate the impact of the Australian fires on the climate of the continent and the whole Earth as a whole. These calculations took into account how the distribution of aerosols and ash was affected by atmospheric currents, as well as hurricanes, dry storms, and other meteorological phenomena.

Calculations carried out by scientists showed that the smoke from the Australian fires rose to a height of 16 kilometers, which allowed a large number of aerosol particles and soot to penetrate into the stratosphere. Their total number, according to scientists, was comparable to how much ash and sulfur compounds enter the atmosphere during large volcanic eruptions.

The penetration of ash and aerosols into the stratosphere led to its record-breaking rapid and powerful heating, which has not been observed since the early 1990s. As a result, the temperature in the stratosphere and in the lower parts of the atmosphere increased by 0.7 degrees Celsius, which was observed for about four months. This suggests that large-scale forest and steppe fires can greatly affect the weather and climate of the Earth at the global level, climatologists summed up.

Camera module for half a smartphone Tecno Phantom X2 camera

In the FCC database, the Tecno Phantom X2 smartphone was lit up, which, first of all, will impress with the dimensions of the main camera module.

As you can see in the drawing, the module will be huge. In terms of the size ratio of the module to the size of the smartphone itself, it is even larger than that of the Xiaomi 12s Ultra.

Of course, the dimensions of the module do not at all mean that the new Tecno will also have a large inch image sensor. Given what the company produces, this is unlikely.

As for other parameters, the FCC base says a 5040 mAh battery with 45-watt charging and Bluetooth 5.3.

With a camera like the Galaxy S23 and a large

This week, high-quality renders of the promising Samsung Galaxy S23 and Galaxy S23 + were leaked to the Web, and now the source has published high-quality images of a much simpler and cheaper model – the Galaxy A14. At the same time, some technical characteristics are also given.

Perhaps the most interesting thing here is the execution of the main camera with “island” (as if separate) modules. The Galaxy S23/S23+ should get the same external camera. But there will be no embedded camera on the screen: the Galaxy A14 will receive an Infinity-U display with a drop-shaped front camera. But the screen itself will become larger – the diagonal will be 6.8 inches.

Galaxy A14 dimensions will be 167.7 x 78.7 x 9.3 mm. The phone is credited with an almost flat side frame, a side fingerprint scanner, a USB-C port. There will also be a standard headphone jack.

Steve Hemmerstoffer, known on Twitter as Onleaks, is behind the leak of these images. He previously published renders of Xiaomi 12 and Xiaomi 12 Pro, Samsung Galaxy S21, Sony Xperia XZ4, Google Pixel 4 XL, Huawei Mate 40 Pro, Sony Xperia 10 III before their official premiere, and all these leaks were subsequently confirmed.

Buy a new model to upgrade from Snapdragon 695 5G

Smartphone Motorola Moto G72, which we talked about the other day, is now almost completely declassified.

To start with, the Moto G72 will not support 5G networks, while the Moto G71 does. Or, perhaps there will be a separate version of the Moto G72 5G, but we don’t know anything about it yet.

As a result, if the Moto G71 relied on the Snapdragon 695, then the G72 will receive the MediaTek Helio G99. And the first not only stands out with 5G support, but it is simply faster. But Moto G72 may be cheaper, but there is no data yet.

The novelty will also receive a 6.6-inch 120-Hz pOLED screen with Full HD + resolution, 6 or 8 GB of RAM, 128 GB of flash memory, a 5000 mAh battery with support for 30-watt charging, and a 108-megapixel main camera. . There will also be moisture protection (IP52), which is familiar to Motorola smartphones.
