Local Sea Level Rise- one of the trickiest predictions, part 4: Distribution delay and freshwater forcing This is the final post of my 4 part series on why sea level rise is not distributed equally throughout the world’s oceans. If you missed the first posts, here are the links; (http://on.fb.me/1C2B9Lx , http://on.fb.me/1JsFhdw andhttp://on.fb.me/1CL9HST. In this final post, I’ll explain the distribution delay and freshwater forcing mechanisms that can influence different sea levels worldwide. Ice melting from glaciers and ice sheets contributes immediately to the global mean sea level rise but is not instantaneously uniform throughout the globe. It takes time for water to become distributed globally. For example, melt water from Greenland contributes to sea level rise in the North Atlantic within months, but can be on the decadal time scale to have a worldwide effect due to boundary, Kelvin and Rossby waves (these explain some of the physics behind water movement in the worlds oceans). A similar process can be observed with melt water from the Antarctic. It isn’t that simple though – for example, changes in atmospheric patterns due to the melting of the Greenland Ice Sheet could result in sea level changes in the Pacific within months. Another aspect of freshwater forcing that should be of concern, particularly those on the North American Coast is the weakening of the overturning process that drives ocean currents. In North America, the warm Gulf Stream flows north until it reaches an area between the UK and Greenland where it cools (becoming denser) and sinks. This deep, cold water then flows south-west until it eventually rises and heads back north as warm water once again. Increased freshwater input from the melting of Greenland’s Ice Sheet is diluting the dense salty water which impedes the waters ability to sink. A warmer North Atlantic region may also slow the cooling of the Gulf Stream, further inhibiting its ability to sink and flow. But what does all of that mean? Simply put, if less cool water is sinking, the out flow of Gulf Stream will slow. The slowing of that oceanic current will cause a build-up of water behind it, which is one reason why the North American coast is vulnerable to the fastest and largest sea level rise this century. Increased freshwater input from Antarctic Ice Sheet melt water could also have severe global implications, as the Antarctic Circumpolar Current is the ‘engine room’ of global ocean circulation. I have touched on this in a previous post (although not with respect to sea level rise), see:http://on.fb.me/1MRhJo7 This series of posts was simply an overview of the complications in local sea level rise predictions. Other factors such as land depression from oil extraction and thermal expansion estimates further complicate the predictions. But hopefully now you have an idea of how difficult sea level rise is to predict, especially for a particular region! -MJA Image Credit: James Balog , illustrating melt water on the Greenland Ice Sheet.

Which are the Children Charitable Trusts in India? Childhood is a phase that is meant to be nurtured and cherished for a lifetime. On one hand, where millions of children are receiving the needed care, on the other hand, there are millions who are deprived of even the basic necessities such as nutritious food, health facilities, and education. To uphold the childhood of the latter group of children who struggle each day, many charitable trusts in India and the world have engaged their time and effort; and one such charity is The Akshaya Patra Foundation.

Day 9: #ground … I always think it’s stunning how #life is powerful… #augustbreak2019 Un pugno di terra…eppure guarda quanta #vita!!!! (Però sono sincera, per il giorno 9 stavo per mettere una foto di #lenemarlin… questa parola la associo sempre ad un verso “Maybe one time lost But now you’re found Stand right up before You hit the ground Maybe one time lost But now you’re found Stand right up before You hit the ground, hit the ground”) (presso Treviso, Italy) https://www.instagram.com/p/B0_3DSCIDCS/?igshid=jsnubfy1u7ez

Bunny has asked more than once, “Why don’t you put whole #boiledeggs in the #meatloaf?” I smh, “One day I’ll do it.” I was near Wayland’s Meat Market in Dimond the other day, bought some #ground round. Thought of mama, since she would send me to Jack’s Meats when I was a kid to do the same. I used her recipe but added some #groundchuck, #carmelizedonion, #worcestershire sauce & the dang #eggs. As I formed the meatloaves, I heard mama whisper, “I think the whole eggs are strange too but if it will make him happy, then it’s ok.” Yup, the #thingswedoforlove. #tinatamalecooks #imissmymama #cookingwithmamatamale #haycomidaenlacasa #comfortfood (at Old Oakland) https://www.instagram.com/p/B0_OQIEBO3C/?igshid=1miv3uhzbl93w

Aint is an important part of the ecosystem in Costranos Grove, but not particularly interesting. On the other hand, Its evolved form, Tremorax, hosts thousands of baby Aint in the ant-farm like structure on its tail!
