Gaseous signaling molecules

Greenhouse gas concentrations in the atmosphere reached new record highs in 2023, locking in future temperature increases for years to come, the United Nations warned on Monday.

Levels of the three main greenhouse gases, the climate-warming carbon dioxide, methane and nitrous oxide, all increased yet again last year, the U.N.'s weather and climate agency said.

It never occurred to Baki Bajraktari that the presence of hydrogen in the Bulqize chrome mine where he works in northeastern Albania could be considered good news: a colleague died in an explosion in 2011 when a team hit a gas pocket.

As winter nears, European nations, desperate to replace the natural gas they once bought from Russia, have embraced a short-term fix: A series of roughly 20 floating terminals that would receive liquefied natural gas from other countries and convert it into heating fuel.

At least one person has been killed following a huge explosion on Jan. 14 at a petrochemical plant in the industrial Catalan city of Tarragona.

The blast was so strong that it caused a building around three kilometers (about two miles) away to collapse. It was there that the death occurred.

Firefighters have found the body of a second victim following a massive explosion and fire at a chemical factory in northeastern Spain, they said on Jan. 15.

The explosion in Tarragona a day earlier left another eight injured, rescue officials said, and the fire continued to burn on Jan. 15.

US air carrier JetBlue is beginning to use recycled fuel to cause less environmental damage. The innovative solution is part of a major plan by the company to support nature conservation, writes BBC.

JetBlue has announced that they'll carbon offset all of their domestic flights as of July 2020.

Daytime speed limits on Dutch roads must be lowered to 100 km / h in order for the country to cope with its emissions and nitrogen oxide pollution, Dutch media quoted by economic.bg.

Prime Minister Mark Rutte said it was an "unpleasant measure" but necessary. The existing limit of 130 km / h will still be allowed overnight.

The molecules, containing carbon and hydrogen, are locked in rocks that are 3 billion years old. Scientists also discovered that the amount of methane gas in the Martian atmosphere changes with the seasons, although the cause of these fluctuations was not clear.     

US scientists have discovered a lake at the bottom of the Gulf of Mexico, BNT reported. The water in it is about five times saline compared to the surrounding. It also contains poisonous concentrations of methane and hydrogen sulphide and therefore does not mix with the surrounding sea water. If an animal or person enters this pool, toxic chemicals can be deadly.

Australian and New Zealand scientists have discovered two new types of bacteria previously believed to be impossible to live on Earth, the Tape reported.
