Climate change is affecting the nights – Temperatures are rising faster

A new British study that describes how the climate is changing temperatures

Climate change affects nights and days differently in much of the world, including Europe, with the former raising temperatures faster than the latter. This shows a new British scientific study, according to which between 1983-2017 there was a difference of rise above 0.25 degrees Celsius in the average annual temperature between nights and days on about half the planet.

In recent decades the days are heating up faster in some countries and the nights in others, but the total land area of ​​the Earth where the temperature rises the most at night is more than double that of the region where the temperature rises faster during the day.

Europe, West Africa, southwestern America and Central Asia are among the regions where nighttime temperatures are rising faster than daytime. In contrast, in the southern United States, Mexico and the Middle East, days are heating up faster.

This “temperature asymmetry” is largely due to changes in cloud cover levels. Increased clouds block the sun’s rays and thus drop the temperature during the day, while maintaining a relatively high temperature and humidity at night. The opposite happens when the clouds decrease, so more heat reaches the Earth during the day and is lost at night.

Researchers at the University of Exeter, led by Dr. Daniel Cox, who published in the journal Global Change Biology, said that “this asymmetry has potentially significant implications for the natural world.” According to Cox, “the greatest rise in temperature at night is related to the wetter climate, which has important implications for plant growth and how species such as mammals and insects interact.

Chinese experimental coronavirus vaccine safe in first stage trials

A Chinese experimental vaccine against COVID-19 developed by the Institute of Medical Biology under the Chinese Academy of Medical Sciences shows safe in a first-stage clinical trial. In Stage 1 of the clinical trial in 191 healthy participants between the ages of 18 and 59, vaccination with the institute’s experimental vaccine showed no serious side effects, the researchers said in their pre-publication.

The most common side effects reported by participants in the trial of this Chinese vaccine were mild pain, slight fatigue and redness, itching and swelling at the site of the vaccine. The candidate vaccine elicited an immune response.

All the evidence from this trial suggests that this inactivated vaccine is safe and elicits an immune response and is encouraging in further studies of its effectiveness in the future,” the researchers said in their report.

China has vaccinated hundreds of thousands of workers in key sectors, as well as people in high-risk groups, with other experimental coronavirus vaccines, although their clinical trials have not yet been completed, raising concerns among experts about their safety. China has at least four experimental vaccines in the final stages of clinical trials.

Instagram will automatically hide offensive comments

Instagram will automatically begin to hide offensive comments as part of its ongoing effort to tackle cyberbullying.

According to CNN, the company said that the comments that will be hidden will be similar to those that users have reported in the past.

The announcement for the pilot application of the service was made today (6/10), on the day of the birthday of Instagram, which closes ten years of operation.

Instagram said it uses artificial intelligence systems to detect comments of intimidation or harassment. Users, however, will still be able to click “show hidden comments” to see specific comments.

The users with restrict button can restrict another person so that their comments are not visible

In fact, last year Instagram added the “Restrict” tool, through which the user can restrict another person so that their comments are not visible to other users.

Various other tools are available to users, such as informing that a comment may be considered offensive before it is published.

People on Instagram say that these actions have improved the situation, while Twitter has conducted similar tests for comments.
