New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2.

What if Earth's atmosphere was infused with extra carbon dioxide, mused amateur scientist Eunice Foote in an 1856 research paper that concluded the gas was very good at absorbing heat.
"An atmosphere of that gas would give to our earth a high temperature," she wrote in the study, published in the American Journal of Science and Arts and then swiftly forgotten.

Car-manufacturing powerhouse Germany is rushing to join the private sector space race as it looks to ride a boom in mini-launchers for small satellites and compete with major US firms such as SpaceX.
Three projects in particular are making Germany a serious player in the race to provide mini-launchers for the increasing number of small satellites which observe the Earth and provide connectivity for the internet of things and smart vehicles.
At the end of July, German company Rocket Factory Augsburg (RFA) carried out a first successful test of its "RFA One" rocket, igniting the engine for eight seconds at its development site in Kiruna, Sweden.
The rocket's "staged combustion" system is used by Elon Musk's SpaceX and Jeff Bezos's Blue Origin, but is yet to be rolled out in Europe.
Russia’s forests store more carbon than previously thought

Russia has the largest area of forest on the planet, with more than a fifth of the world's trees. A new study, led by Russian scientists using data from ESA’s Climate Change Initiative, has produced new estimates of biomass contained in Russian forests, and confirms that the vast forested area is storing more carbon than previously estimated.

Boeing delays key uncrewed test flight to ISS
Tuesday, 03 August 2021 14:36 Write a comment
Boeing said Tuesday it was delaying an uncrewed flight of its Starliner capsule to the International Space Station (ISS), pushing back a key test it last attempted in 2019.
The spaceship had been due to launch on a United Launch Alliance (ULA) Atlas V rocket built from the Cape Canaveral Space Force Station in Florida at 1:20 pm Eastern time (1720 GMT).
"We're confirming today's #Starliner Orbital Flight Test-2 launch is scrubbed," Boeing Space tweeted.
Boeing said more details would be forthcoming soon, but a weather update in the morning had placed the chances of launch at only 50 percent.
The test flight was supposed to take place Friday but had to be rescheduled after a Russian science module inadvertently fired its thrusters following docking with the ISS, pushing the orbital outpost off kilter.

Russia is planning to stop using the International Space Station by 2028 and create a national space station instead given risks posed by ISS worn-out equipment, state space agency Roscosmos said on Saturday.
The corporation's Scientific and Technical Council held a meeting earlier in the day.

The sudden activation of engines of Russia's Nauka multipurpose laboratory module at the International Space Station (ISS) was triggered by a software failure that was quickly fixed, Russia's ISS segment chief, Vladimir Solovyov, explained on Friday.
"The mechanic aspect of the docking was reliable, without any remarks registered. This resulted in the closure of both docking mechanisms: th
