Nuclear Bombs Exploded At Bikini Atoll

Nuclear Bombs

 
There were 22 nuclear bombs exploded at Bikina Atoll with devastating effects.
 
What is an atoll?
 
Atoll is a word used to describe a ring shaped coral reef. The word itself, taken from what the Mayalalam peaople call the Maldive Islands, is “atolu.”
 
But a true atoll is not like the Maldives. An atoll is a circular coral reef system formed at the peak of an underwater extinct volcano.
 
At Bikini Atoll is a chain of coral islands. Situated in the central Pacific Ocean, nuclear bombs detonated there created massive craters. Destruction caused by detonation of the bombs has now been revealed by scientists.
 
The first nuclear bomb test, codenamed “Baker,” was detonated underwater in July 1946. In a milliesecond, a 274 metre wide column of sand, pulverised coral and water shot to 1.6 kilometres in the air. 22 of these bombs were detonated between 1946 and 1958.
 
What we do not know is what the long term effects of such actions will be. It is clear that the coral was destroyed alongside unknown amounts of sea life. Does exploding nuclear devices in this way contaminate the ocean?
 
I beleive it must. Does this mean then that we eat seafood? You tell me.
 
Back to the atoll. The US bombs have caused two enormous craters in the sea bed. These craters cover an area around 1.5 times the size of New Yorks Central Park. They have now been measured accurately to a depth of 56 metres.
 
Detonating a bomb that causes that much devastation must have ramifications.
 
We know that Earth has seven tectonic plates. We also know that these plates are always moving. So what other harm has the testing of nuclear bombs at sea done?
 
Has it caused the fault lines that existed to lengthen?
 
Has it altered the height or angle of the Pacific plate? Not having the technology in the 1940’s to measure as we do now, who can say?
 
So 70 years on and we are still testing nuclear weapons. North Korea, for example, does it.
 
Will we never learn?
 
France also used atolls in it’s atomic bomb tests.

Climate Change And Sea Turtles

Climate change Puts Sea Turtles At Risk

You will be aware that Sea Turtles lay their eggs on land. Climate change is threatening their existence. Even though they can live up to the age of 150 years. The average is a 50-year life span.

climate change

Sea Turtles drag themselves up the beach away from the shoreline to bury eggs in the sand. Six to eight weeks later, the hatchlings dig their way up to the surface and face a perilous journey to the ocean. Seagulls and Skuas know when the hatch takes place. They wait for an easy dinner when the baby turtles surface.

The hatchlings that make it to the water are still not safe. One in One Thousand hatchlings are likely to survive.

Now a new fear has arisen. The Scientific Community and Nature Conservation bodies are in agreement. Climate change will cause rising sea levels. Add the increase in severe weather events and the outcome is clear.

The waterline will rise. The beaches will erode. These factors will destroy the nesting sites of the Sea Turtles. Then, in turn, the population will drop. There will be fewer hatchlings, yet the same number will die on the way to the ocean. And so the population dwindles. All due to climate change.

this tied with two other years, 2007 and 2016. Recording arctic sea ice levels began in 1970. This tells you that scientists must have been aware of climate change for 50 years.

What is the Artcic Sea Ice?

Arctic sea ice is a vast area of seawater that is frozen and floats on the Arctic Ocean.

It grows each year in the Northern winter and shinks again in the 6 months of Arctic summer.
Historical data now shows that the ice area is less across both seasons in the Arctic. This affects the ecology of the area as a whole. More icebergs are now freed from the main body of ice. Weather patterns change and the ocean currents alter.

Arctic Sea Ice


A quote from climate change senior scientist Claire Parkinson. “This year’s minimum sea ice extent shows that there is no sign that the sea ice cover is rebounding.” This means that the ice amounts will continue to deplete.

Rising ocean levels will contribute to changes in weather patterns.
Ice melts every summer. We all know that. But the changes in climate mean the ice does not recover fully in the freeze season.
As the 2019 Arctic sea ice lowest on record data shows, we are gripped in a constant loss of ice. Coupled with rising temperatures, extreme weather events will become more frequent.

Australian woman Finds Mammoth Tusk Due To Global Warming

Mammoth tusk

Mammoth Tusk found by australian geologist

The Mammoth Tusk was found by an Australian Geologist known as ‘Thora The Explorer’ while holidaying in Alaska. She spotted a bit of a blue, curved object, protruding from the mud.

She soon recognised that she had found a Mammoth’s tusk. The tusk is estimated at a minimum of 10,000 years old.

The main reason that the tusk became visible is the more and more of the permafrost has melted over the last few years.

While this is a wonderful find that anyone would treasure, it is another indication that our governments need to make urgent changes to prevent more melting of the permafrost and glaciers.

The tusk had been turned blue by thousands of years of mineralisation.

Major causes of climate change

Major causes of climate change

Major causes of climate change

 
 
Our activities are the cause of climate change. Chopping down forests, burning coal, oil, gas, and land clearance are the main ones. When we burn these fossil fuels large amounts of carbon dioxide (CO2) get released. This CO2 accumulates in Earths atmosphere. Deforestation reduces the number of trees available to consume excess CO2.
 
 
Increases in CO2 and other greenhouse gases prevent solar radiation from escaping. This traps heat and raises the temperature on Earths surface. This is the “Greenhouse Effect.”
 
The greenhouse effect keeps Earth warm and habitable. Unfortunately, human activities intensify the heat causing the planet to overheat. This the “Enhanced Greenhouse Effect.”

Impacts of a warming climate

greta thunberg
Different regions on our planet experience different effects of climate change. That is, the temperature rises at different rates depending on the region.
 
Many areas experience unpredictable and extreme weather events. Some become colder or drier. Others may become wetter or hotter.
 
Projections by the scientific community say that our climate could raise by as much as 6 in the next 80 years. Cutting carbon emissions could, at least, lessen this.
 
An increase of 6 is likely to affect crucial food chains and fragile ecosystems. This would result in massive rain-forest destruction. Sea levels will rise by large amounts. Ice sheets will also melt in our polar regions.
 
As a result, we and other life on or planet would suffer greatly.
 
I will look at the effects of climate change on wildlife in my next post.
