What If We “Got Shot” of the Moon? :   23 comments


No “Year In Review” From WordPress….So!

What If We “Got Shot” of the Moon?!!

‘The geological history of the moon and Earth are intimately tied together such that the Earth would be a dramatically different planet without the moon.’

It would? So what exactly would happen if we just got rid of it altogether and there was no moon? Which there probably wasn’t so far as many of us were concerned over Christmas! But say we blew it up?!! Blasted it completely out of the sky? After all do we actually need this shiny ball in the sky anyway?

The Birth of a New Ring World Earth Surprised smile

All those tiny fragments of blown up moon would be far too small to stick back together and create a new, if rather misshapen and little moon, which would have at least managed a near normal gravitational pull on Earth…important scientific detail….

A lovely ring would form around Earth consisting of little lumps of moon shrapnel …very, very tiny ones…very pretty but trouble is they wouldn’t be content with staying out there in space. Oh no, they would much rather make a regular and devastatingly determined habit of periodically hurtling out of their ring-world and slam-dunking into the Earth’s surface, bombarding us with meteorites that should otherwise never have thought of coming anywhere near us…oh dear! Moulton moon rain, cities destroyed, countries obliterated….

Moon formedImage NASA JPL-CaltechOn top of which, if we have blown the moon sky high all those particularly dangerous outer space meteorites that had previously hammered the moon’s surface would no longer have anything to prevent them making a bee-line for Earth, happily re-creating the Moon’s surface on the home-world! Great! Craters everywhere… Even more cities destroyed, countries obliterated….








Axial Tilt of Earth Eye rolling smile

In between moon rocks and meteorite bombardments from the rest of the cosmos, Earth, minus the moon’s gravitational pull would develop a wobble…it had a little one before but it was stabilised by the Moon, which also protected it from the gravitational pull of the other planets…now it would have a huge wobble, and be pulled one way by Mars and another way by Jupiter – our planetary neighbours. Consequently with no moon to slow Earth’s orbit down we would be flying merrily around the sun in a wildly unhinged and erratic orbit…. shortening Earth’s day from 24 hours to only 8 – 10 hours.

Catastrophic seasonal changes Disappointed smile

moon_asexuality.orgOn top of which whilst currently we are worrying about global warming and climate change….or at least those of us with a scrap of common sense are, with the moon gone these problems will seem trivial….of course to the uneducated or just plain stupid they already are, but you “aint seen nothing yet!!”

Earth would be a very, very different place. As it would now be rotating so much faster, 160-200 km winds would be zooming across Earth’s surface.








With Earth’s now unstable axial tilt, we would see dramatic environmental changes over the course of thousands-millions of years – the loss of our conventional seasons and radical modifications in temperature would cause wide-ranging consequences for the growth of plant life and crops. This in turn would create some major headaches and very thorny problems for producing food for the billions of people dwelling on Earth. The animal world would have to adapt pretty quickly to a much shorter life pattern in terms of mating, migration and hibernation.


Moreover, the changing temperatures would lead to the loss of Earth’s N and S Poles. To an extent this is already happening but in such circumstances melting ice would have a hugely dramatic effect on the oceans which would rise to a point where they change the all the world’s coastlines.

Life on Earth both in countries and in cities would have no choice but to adapt pretty drastically in order to survive or disappear into extinction.


Tidal Chaos Confused smile

With no moon to affect the tides, which show a configuration related to the lunar phase cycle, Earth’s oceans would become very tranquil and still. Solar tides would have a very small effect; about half that of the Moon, so there would be the odd wave or two. (Assuming we hadn’t blown the Sun up as well 😉 ) Tides were also important in life’s early stages of evolution so this would be terrible news for sea life which would rapidly become extinct. Barely-there tides do not mix oceans which therefore do not circulate nutrients required for sea-life’s survival…so fishermen would quickly go out of business and no –one would be microwaving their “Fisherman’s Pies” ever again!

Coral Reefs and Climatic Change

CoralReef  bonaire-flower-coral

Corals themselves are tiny animals which belong to the group cnidaria (the “c” is silent)which also include hydras, jellyfish, and sea anemones. Corals are not mobile but stay fixed in one place. They feed by reaching out with tentacles to catch prey such as small fish and planktonic animals. Corals live in colonies consisting of many individuals, each of which is called polyp.

It was believed in the Middle Ages that sea fish were created to balance with the stars in the sky and were consequently equally numerous.



  • Corals are amongst the oldest eco systems on Earth and the largest living structure on the planet.
  • They cover less than 1% of Earth’s surface but are home to 25% of all marine life
  • They protect our shorelines from erosion
  • Provide food and livelihoods for 500 million+ people
  • Used in treatment of cancer, HIV, cardiovascular diseases and ulcers
  • Corals porous limestone skeletons have been used for human bone grafts
  • 1/3 of our corals are now threatened with extinction. At present destruction rates 70% of the world’s coral reefs will be destroyed by 2050


Rising Temperatures (Global Warming)

  • This puts strain on corals which then eject the algae (zooxanthellae) that live in their soft tissue, providing nutrients and energy for photosynthesis. Algae also give corals their bright rainbows of colours. Without algae the coral becomes bleached and open to disease.


Atmospheric CO2 (Ocean Acidification)

  • Oceans become increasingly acidic as they absorb Carbon Dioxide from the atmosphere. Coral reefs have limestone foundations and the acidity is responsible for them dissolving, which has a critical affect on a corals ability to grow.

With the exception of amphibians corals are at higher risk of extinction than all the terrestrial animals groups…they are also the most sensitive to climatic changes.

Destruction of their habitats, overfishing, ocean warming, increased risk of acidification and millions of tonnes of nutrient run-off all play a part in this situation.


Global Dead Zones

Regions of coastal seawater that have been deprived of oxygen as a result of fertilisers and sewage overspill, consequently, can no longer support life. Twice as many such zones have developed since 1960. Coupled with rising Carbon Dioxide levels not only shallow-water marine life, but also numerous deep-sea species will also suffer and die.

  • SWEDEN – cyanobacteria is blooming resulting in the Baltic Sea becoming a deadly, toxic brown sludge.
  • HAWAII – Massive stacks of fetid, contaminated green-brown algae dumped on the ocean coasts.
  • FLORIDA – Red tides of toxic algal are killing of hundreds of marine mammals….
  • CARIBBEAN – 80% of reefs are suffocated by algae…..


Climate change, coupled with ocean warming, is likely to result in a global collapse of coral reefs within the next few decades. There is clear census of scientific opinion that it is essential to reduce greenhouse gases if coral reefs are to survive.

Fear the heat of the Sun


The Ice Is Melting Too Quickly….. The Climate Is Changing Too Fast…..

Glacial zones around the world are retreating with increasing rapidity. When they have gone, rivers will not flow, sea levels will rise, and millions will die from famine or ‘water wars’.

The world’s glaciers are melting faster now than at any time since records began, threatening catastrophe for hundreds of millions of people and their eco-systems.

Soot pollution from vehicles and industry may be playing as much a part in this as global warming.  Clean white surfaces reflect sunlight and enable it to remain cool.  The soot polluted ice soaks up solar radiation and so the glaciers melt much faster. The smaller they become  the quicker they melt.


The latest report from the World Glacier Monitoring Service adds to the growing alarm about the rise in sea levels and increased reports of flooding, avalanches and drought.


As the climate warms so the glaciers melt, sea levels rise, and the risk of catastrophic fires icreases

Based on historical records and other evidence, the rate at which the glaciers are melting world-wide is faster than at any time in the past 5,000 years.  It is not possible to prevent further increases in atmospheric CO² but even if we could, within a generation the planet’s glaciers will be gone completely.


The only exceptions to this are the currently reasonably stable Antarctic glaciers.  It would be good for them to remain in this condition as if the South Pole loses it’s ice, sea levels will rise by a daunting 70 m (230 ft) and the remaining space left by the mountain glaciers would be the only areas still above water.


This is ‘The Inconvenient Truth’ In trying to get a grip on global warming, we will need to use every tool that is available to us.  Global warming is not a political issue, but a moral and global issue.  For our children and for the future of the human race, it may very well be an issue of survival.
