The state of Hawaii has a bold energy agenda:  it plans to get 100% of its energy from renewable sources by the year 2045.  In order to get there, Hawaii is embracing a diversified mix of renewable energy generation sources.   Of course, Hawaii’s famous sunshine has allowed the state to have the highest per-capital base of installed solar power in the nation.  But it will take more than just solar power for Hawaii to get all of its energy from green sources.

The world’s coral reefs are increasingly threatened by the changing climate.  Both warmer ocean temperatures and increasing ocean acidification are damaging coral populations and endangering the very existence of coral reefs.

We have talked about the plastic blight – the growing presence of discarded plastic polluting our streets and our waterways.  We have discussed the so-called garbage patches in the ocean, composed primarily of plastic.   A new study discusses the effects of ocean plastic pollution on seabirds and the results are horrifying.

It may seem like we are constantly talking about toxic algal blooms – in the ocean, in lakes, and in rivers.  That’s because they are occurring with greater frequency and are posing a greater threat than they have in the past.

It’s no secret that ocean waters are warming, especially in New England.  The waters in the Gulf of Maine are warming 99% faster than the rest of the world’s oceans.  What’s the problem?  Well, lobsters like cold water, and as a result, they’re heading north.

The average surface temperature around the world has gone up over a degree over the past 40 years but some people argue that if the greenhouse effect was really at fault, the temperature rise would be much larger.

Once, the constancy of seawater was taken for granted. Now, as we see evidence of increasing concentrations of mercury in seawater, it is becoming obvious that global pollution is taxing the dilution capacity of the seas. There is also good evidence that the ocean is acidifying.
