Coral reefs face extinction within 50 years: experts
 
Interestingly the article discusses pH issues due to excess CO2 in the atmosphere. I have not heard of this before.

I think the term there using now-a-days is Ocean Acidification, its a sad topic but there has been a fair amount of reseach put into play and it looks like the increase in atmospheric CO2 is really causing some problems for small inverts and the develpment of there carbonate shells. One thing is for sure, something has to be done or we could be looking at some pretty white reefs right away here :cry:.

And to think - there's still climate crisis deniers out there...

This is why I'm not having kids. I dont want to bring anyone into this pathetic world we're creating.

This type of thinking needs to be exported to certain ...countries, LOL.

Sure our population is low but our emissions are not.

We waste so much fresh water. In 10-20 years wars will not be fought over oil but water.

last place amongst the G8... Really - yet we still emit 10% of the US CO2 emmisions...

Yeah, but we forget how this work, CO2 acidifies the water, Calcium carbonate disolves, raising pH ... calcium reactor... Reefs have existed during periods where temperatures were much heigher, atmospheric CO2 much heigher...

Lets keep things in perspective...

C'mon Andy, you're being lazy :P

Pre-industrial Revolution, variable world oceanic pH was 8.0 to 8.3.
Today's average variable oceanic pH is 7.9 to 8.2.
That's over the course of 150 years.

Prehistorical parallels took tens of thousands, if not millions of years. Acidic oceans are not unprecedented (late-Jurassic ~7.5), but the rate at which they are becoming so is.

There's your perspective.

I've given up on climate change... I switched to CFL lights (actually putting me down one rung on the environmental ladder, since they contain toxic mercury and my power is all hydro), I don't drive a car, I buy organic and recycled materials (and recycle those that are worth recycling)... What more can I do?

I need to start breeding endangered species in my living room if I'm to be seen as helping (rather than hindering) these days...
