This was a good video…I’m not sure how to change the course this society is on but we must try.
Using graphene to filter and desalinate saltwater
As the global population increases and water supplies become less predictable due to global warming, finding sources of clean drinking water becomes even more critical. Just ask residents of Cape Town, which expects to run out of water around April 12nd! The obvious solution is to desalinate ocean water, but that’s a very energy-intensive process. Well, researchers in Australia found a way to use a graphene film to act as a filter; its structure allows water molecules to pass through but blocks larger contaminant particles. Most membrane filters get clogged up quickly, but this one keeps working even as it gets coated in contaminants. It’s nowhere near a commercial product yet, but is a promising solution to a growing global concern.

Senators go on the record on Climate Change
Some recent votes have put Senators on the record on their position on climate change. Despite them not being climate scientists themselves, many of them are choosing to ignore the conclusions that the overwhelming majority of climate scientists have reached. Specifically, Senators defeated a proposed amendment that stated that “climate change is real (and) human activity significantly contributes to climate change.” To any educated person, that statement is kinda obvious and not a big deal. However, 49 Senators voted ‘NO’ to that statement. Children of the world…these 49 people are blocking efforts to combat climate change at the Federal government level in this country. The science is indisputable…your future is being put at risk by these and others that agree with them. Know this, and remember this, for in the coming years, chances are there will be some pretty creative spin put on the climate change issue as people worldwide are forced to face the reality…they’ll talk about uncertainties, doubts that people had…but know that the IS no doubt in the climate science community. The only doubt is that which is created by those who seek to block efforts to reduce CO2 emissions (the ‘why’ is a subject for another day, but a quick tip there, just follow the money).

The names of the Senators who voted ‘NO’ are shown below (full results are here). Note that Harry Reid (D-NV) did not vote on this amendment so his position is unknown. Note that not a single Democrat voted ‘NO’. To their credit, five brave Republican Senators broke ranks and voted ‘YES’! Nice to see…but we need more like them!

Climate science: what you need to know
Climate change IS happening and WE are causing it. Here’s a great video that sums up ‘what you need to know’ in 24 simple steps. Check it out, and share!
Computer simulation of CO2 in the atmosphere
This is a really fascinating video showing CO2 levels dispersed throughout the atmosphere over a year, as simulated by NASA’s climate modeling program GEOS-5. It’s really interesting to see how the levels change over the year based on plant growth, and also the stark differences between the northern and southern hemispheres. Check it out below, or read about it more over at Wired.
