Hey everyone!
I have just been reading an article about global warming. I thought you might be interested about this article because, it affects everybody.
Basically, what it talks about is an experiment to dim sun and combat global warming. Scientists hope to prove that spraying tiny particles 12 miles above the earth's surface could reduce global warming by reflecting some of the sun's rays back into space.
It is also said that they believe this would replicate what happened naturally in 1991 when Mount Pinatubo erupted in the Philippines and spewed 2o million tonnes of sulphur dioxide into the stratosphere. This cooled the planet by about 0,5 C for 18 months.

The team will use the results to improve computer models used to predict the impact and risks of geoengineering.
A study by Harvard and Yale scientist found that spraying particles into stratosphere would be a “remarkably inexpensive” way of cooling the planet, costing $2bn-$2,5bn a year.
What shocked me most was that the technology might postpone some global warming but could have disastrous consequences for some countries by altering weather patterns, particularly in the tropics. So, some fears are that particle spraying would damage the ozone layer and disrupt rainfall patterns, causing droughts and famines in some regions.
In my mind it is not a good idea to interfere with nature, because the experiment can also have serious consequences, as we have learned before. Scientists should do a lot more researching before they carry out the experiment in the future.
What do YOU think about the experiment?
I hope you enjoyed my blog posting and you are going to read my next.
See you soon,
