According to scientists around the world, it’s the final call and the most extensive warning on the high risk of rising global temperatures. The report on the rise of temperature says the world is completely out of track when it comes to climate change, heading towards a rise of 3C. The preferred target is 1.5C which is the pre-industrial level.
After an official meeting between scientists and government officials in South Korea, the Intergovernmental Panel on Climate Change (IPCC) issued a special report on the impact of global warming of 1.5C.
The 33-page Summary for Policymakers certainly is under difficult negotiations between climate researchers and political representatives who are more concerned with the economies of their nations and living standards. Prof Jim Skea, who co-chairs the IPCC said:
“The first is that limiting warming to 1.5C brings a lot of benefits compared with limiting it to two degrees. It really reduces the impacts of climate change in very important ways. The second is the unprecedented nature of the changes that are required if we are to limit warming to 1.5C – changes to energy systems, changes to the way we manage land, changes to the way we move around with transportation.”
The impact of climate warming is visible especially in the sea world, coral reefs and the Arctic. Kaisa Kosonen, of Greenpeace, who observed the negotiations said:
“Scientists might want to write in capital letters, ‘ACT NOW, IDIOTS,’ but they need to say that with facts and numbers. And they have.”
Hubble Telescope and Mechanical Failure
The Hubble Space Telescope is currently operating with only essential functions after it lost one of the gyroscopes needed to point the spacecraft.
The observatory stated that one of the most important scientific instruments ever created is in “safe mode,” while scientists try to fix the problem.
Hubble was operating with four of total six gyroscopes when one of them failed on Friday, October 5, 2018.
The Hubble Space Telescope was launched in 1990.
After the gyro failure this weekend, controllers of the telescope tried to switch on a different gyro, but that one was found to be malfunctioning. Currently, Hubble operates with two fully functional gyros.
At any given time in order to work properly, Hubble needs at least three of its gyroscopes to work for optimal efficiency.
At the moment, operators are trying to revive the gyroscope, while flight controllers are trying to bring it online to replace the failed one.
If the gyroscope turns out not to work at all, the orbiting observatory may have to operate only on one gyro. Dr. Rachel Osten, deputy mission head for the Hubble Space Telescope, tweeted recently saying:
“Very stressful weekend. Right now HST is in safe mode while we figure out what to do. Another gyro failed. The first step is to try to bring back the last gyro, which had been off, and is being problematic.”
Solar Panels at Chernobyl Nuclear Power Site
Ukraine recently launched its first solar plant in the middle of the abandoned area around the former nuclear power station. The Chernobyl area was the site of the catastrophic nuclear disaster in 1986. Radioactive materials were released into the atmosphere across Europe leading to a rise in thyroid cancer. Currently, the area around the plant is an exclusion zone with a span of 1000 square miles.
Previously Chernobyl plant was decommissioned and the government was forced to close it in 2000. Ukraine launched their first solar plant in the abandoned area around the former nuclear power station which ended in a disaster more than 30 years ago.
Ukraine’s government wants renewable energy companies to develop in the abandoned land around Chernobyl. The site will be able to create enough energy to power approximately 2,000 households. Still, people won’t be able to return to live in the zone which will remain abandoned for another 24,000 years. The combination of renewable energy and the nuclear catastrophe from 1986 has its own deeper meaning in the world of climate change. Using an area which is inhabitable for good is one step closer to making changes which will be beneficial to all.
