GRB 020813 gamma ray observed in 2002 and lasting 2 minutes.

An explosion of cosmic gamma rays with Earth could be detrimental to ocean plankton at depths of up to 80 m, according to a team of Cuban researchers. These organisms represent up to 40% of the ocean’s photosynthesis, and if such an event occurs, it could have a serious impact on the Earth’s carbon dioxide levels.

Gamma-ray burst or bursts (GRBs in English) are the brightest electromagnetic events known in the universe.

These gamma-ray bursts, are caused by the collapse of a massive star at the end of its life which begins a rapid rotation. a black hole forming during the death of the massive star produced these gamma rays that carry the power of billions of nuclear bombs

What are the CO2 readings from that Gamma ray burst?

 

[Dalia]

The spectrum of GRB 011211 was reported to include emission lines associated with the chemical elements magnesium, silicon, sulphur, argon, and calcium, which supported the theory that gamma-ray bursts are preceded by highly massive stars undergoing a supernova collapse.However, these results were considered statistically insignificant and somewhat controversial due to the low resolution of the instruments used. The spectrum of GRB 020813 was also found to display emission lines of elements associated with supernovae, in this case sulphur and silicon.This evidence confirmed the connection between supernovae and gamma-ray bursts.

I hate it when that happens. It just makes me so angry!

You won’t have much time to be angry we’re small in the universe and it’s possible we’ll experience such a catastrophe

Imagine, the only life in the universe gone. Do you think that's what they mean by the second coming?

Ok, Praise Allah! I thought a gamma ray burst hitting Earth might be problematic, but there's virtually no CO2, so, no worries

Gamma-ray burst 'hit Earth in 8th Century'

A gamma ray burst, the most powerful explosion known in the Universe, may have hit the Earth in the 8th Century.

In 2012 researchers found evidence that our planet had been struck by a blast of radiation during the Middle Ages, but there was debate over what kind of cosmic event could have caused this.
Now a study suggests it was the result of two black holes or neutron stars merging in our galaxy.
This collision would have hurled out vast amounts of energy.

Does this have something to do with "climate change?"
