Satellites are key to monitoring ocean carbon

Satellites now play a key role in monitoring carbon levels in oceans, but we are only now beginning to understand their full potential.

 

Our ability to predict future climate relies on being able to monitor where our carbon emissions go. We will need to know how much stays in the atmosphere, or becomes stored in the oceans or on land. The oceans in particular have helped to slow climate change as they absorb and store the carbon for thousands of years. This critical role the oceans play in regulating our climate will require monitoring and understanding.

Keeping an eye on the oceans will be a huge job, in part because of their sheer mass, covering 70% of the Earth’s surface…a perfect opportunity for satellites to shine.

 

Satellites previously launched to study the movement of wind can also observe the waves, foam and temperature and how they combine to control the movement of heat and carbon dioxide  between the ocean and the atmosphere.

Further , satellites used to monitor gas emissions over land can also be used to measure carbon dioxide  emissions as they disperse over water.

By monitoring the oceans we can gather the necessary information to help protect ecosystems at risk.

Drinking Tigers

Here we have a video that is going viral. We have a lovely family of Tigers drinking water from a river. The video is provided by Susanta Nanda of the Indian Forest Service.

The big cats can live for two weeks without food , but only 4 days max without water.  We all need good clean water to sustain our lives.

Second Ever Interstellar Comet Contains Alien Water

Astronomers has spotted signs of water spraying off comet 21/Borisov, which is flying towards the Sun on a journey from interstellar space. This is the first time scientists have seen water in our solar system that originated elsewhere.

Olivier Hainaut, an astronmer at the European Southern Observatory in Garching, Germany..says the discovery is not surprising because most comets contain much water. What is interesting about this one is being able to confirm it’s presence in a interstellar comet and taking us another step toward understanding how water can move between the stars.

 

Astronomers have been able to track Borisov since its discovery on August 30th with excitement as the tracking shows the origin in deep space. Possibly billions of years ago it got knocked away from where it was to a trajectory that brought it to us today.

On October 11 scientists spotted the telltale signature of oxygen in the spectre of light coming from the comet..most likely from water breaking apart into hydrogen and oxygen.

 

Borisov will fly past the Sun in early December, as it gets closer the heat will cause the icy nucleus to spray out gas and dust. A big show for the scientists and a bounty of information to work with.

Changes coming to water bottling permits in Ontario

A decision on how to proceed with water bottling permits is expected by early to mid-December says Ontario’s Environment Minister Jeff Yurek.

 

On January 1st a moratorium on new and expanded permits to take water for bottling is set to expire. the decision on how to move forward is to be science based, but if no conclusive information is found then it is possible the moratorium will be extended.

Communities, first nations peoples, and businesses are all being consulted, as well as the scientific study.

The moratorium was put in place due to Nestle purchasing a well near Guelph. Concerns were expressed about the effect this would have on the future drinking water supply in the Township of Wellington Centre. Liberals increased the fees for bottlers from $3.71 per million litres of ground water to $503.71 per million litres. Water bottling companies have been able to take millions of litres a day.

 

A balance between all sides needs to be found..a tricky solution indeed.
