Giant Earthworm and Hottest Period
What’s in news?
The world is falling badly behind in the race to avert climate disaster, with the five-year period ending 2019 set to be the hottest ever.
- World Meteorological Organization compiled and published a report of UN which comes at the time of UN Climate Action Summit that will push countries to increase their greenhouse gas reduction targets.
- The average global temperature between 2015 and 2019 to be the hottest of any five-year period on record.
- The temperature which estimated to be 1.1 degrees Celsius [34F] above pre-industrial [1850-1900] times and 0.2 degrees Celsius [32.4F] warmer than 2011-2015 during this period.
- The Arctic summer sea ice has declined at a rate of 12% per decade over the past 40 years, with the four lowest values between 2015 and 2019.
- The Antarctica’s ice sheets loss increased by a factor of six between 1979 and 2017.
- Carbon dioxide grew 2% in 2018, reaching a record high of 37 billion tonnes.
- There is also no sign yet of reaching what is known as “peak emissions,” the point at which levels will start to fall, though these are not growing at the same rate as the global economy.
GIANT EARTHWORM FOUND
What’s in news?
A “snake-like creature” found while removing soil for roadwork in Mangaluru. It has not been reported in the Western Ghats and the coastal belt of Karnataka so far.
- The earthworm has been preserved in chemical solutions at the laboratory of the department at the Mangalagangotri campus of the university.
- This was the first time such a large earthworm had been sighted in the Western Ghats and the coastal belt.
- When stretched, the earthworm measures 950 mm (more than 3 feet) and is 20 mm in width
- In India, J.M. Julka (2008) had reported the largest earthworm — Drawida nilamburensis, which belongs to the Moniligastridae family. That specimen, from the Nilgiris, measured up to 1,000 mm in length.
- Morphological study of the newly discovered earthworm has tentatively indicated that it belongs to the genus of Moniligaster.
- If internal structures are to be studied, the department would need another earthworm of the same size or category for dissection purposes.
