Beautiful Warnings….

The cherry trees lining the street where I work now are in bloom.  I have the privilege of walking by them several days a week.  Many of the buds have opened.

The "For Rent" sign was removed from this nest on Monday afternoon.  Renovations are underway and the new tenants are noisy and cheeky....

This afternoon, there are more blossoms open.  Tomorrow the show of pink against blue should be stunning.

Tuesday Blossoms and the sky is even bluer....

Tuesday Blossoms and the sky is even bluer….

 

I have been privileged to stand watch as a four hour sunset turned into a four hour sunrise.  That was many July’s ago during a 12 hour graveyard shift on the roof of a coker at Syncrude.

I do not have a photograph, only memories…  Inside the plant, personal cameras are not allowed to be carried by employees.

 

Today is February 23, 2014.

The photos of the cherry blossoms were taken in Richmond, British Columbia, Canada where in February’s past we have huddled under umbrellas, pulling our jackets close as the cold winds blew in off of the water.  I grew up here.  The cold winds and wet weather of winter are what is necessary to keep the rain forests green.

 

Climate change is real.

 

I have recently read Naomi Klein’s newest book, This Changes Everything:  Capitalism vs. The Climate.  I do not believe that she exaggerates any point.

 

Every small thing we do (or don’t do) to stop the change helps.

Mangrove Forests….

I just found a wonderful and interactive site!  Well, this isn’t just a site, this is a database and, it is worth a visit….

Now, I tried to put the following into my own words but, it is so perfectly written that I have copied and pasted it here for you:

A Case for Mangroves
The approximately 70 distinct species of mangroves in the world cover roughly 17,000,000 hectares globally (Valiela et al.  2001) – only 0.12 percent of the Earth’s surface (Sullivan 2005, Ellison 2008).  The greatest diversity is in Southeast Asia (36-46 species); the lowest diversity is in the United States and the Middle East (1-3 species) (Polidoro et al.  2010).  Mangroves are being cut down or otherwise destroyed at such a high rate that they may be functionally extinct by 2100 (Duke et al.  2007).  In just the last 50 years, 30-50 percent of the global acreage has been lost.  (Alongi 2002, Duke et al. 2007)  Mangroves are among the most valuable and most threatened ecosystems on Earth.  The ecosystems services they provide—e.g., buffering coastal communities against flooding and storms, fiber production, habitat for thousands of species of birds, mammals and marine species—are estimated to be worth US $1.6 billion dollars/year (Polidoro et al.  2010).  In addition, recent evidence suggests that mangroves sequester carbon more effectively than any other tropical forest (Donato et al.  2011).”

This is important!

There are 65 of the most influential papers on mangroves and mangrove forests listed on this site.  All are worth reading but, we don’t all have that much time….

If there is a paper that you feel is missing, please add it in the comments below.  I look forward to hearing from you.

 

Links to Two Articles on Molecular Cell Biology – Yes, I do read this stuff….

I am placing the link information for these articles here with the thought that easier access to articles such as this will encourage reading (or, maybe in this case curiosity) and open discussion.  This is also an open invitation for you to write a precis on this article (or, any other article that you find necessary or interesting)….

Once you actually get into reading articles like these ones, they are not nearly as intimidating as they could be!  This particular article even gives you some of the trickier definitions in the marginalia.

You can find more Biochemistry articles here.
