Sea Ice Antarctic news.
Yep, it is shrinking.
Below is a summary about recent sea ice news.
Antarctic sea ice likely shrunk to a record low last week, US researchers said Monday, its lowest extent in the 45 years of satellite record-keeping.
The Antarctic cycle undergoes significant annual variations during its summers of thawing and winters of freezing, and the continent has not experienced the rapid melting of the past four decades that plague the ice sheets of Greenland and the Arctic due to global warming.
But the high melt rate since 2016 raises concerns that a significant downward trend may be taking hold.
Melting of the sea ice is problematic because it helps accelerate global warming.
When white sea ice—which bounces up to 90 percent of the Sun's energy back into space—is replaced by dark, unfrozen sea, the water absorbs a similar percentage of the Sun's heat instead.

Due to rising sea levels and increasing precipitation from climate change, research says that in some areas, like the Gulf Coast, back to back hurricanes could occur as frequently as once every 3 years. Researchers led by Ning Lin, an associate professor civil and environmental engineering at Princeton University feel "Today's extremely rare events will become far more frequent." Storms that might have passed with little notice in the past will become threats, particularly when they hit one after another due to soil saturation. A major takeaway from this research is the need to plan for the ramifications of back to back storms.
*Hopefully the U.S. government and local officials are reading this study too.

Someone recently made a post that I haven’t located yet, it was about the destruction of trees and landscape, maybe it was in Florida, and the terrible sense of loss. I thought about it for a few days and made a little (not quite semantically correct) collage about it. Then I began researching the rights of nature, something I was dimly aware of, and found that while it’s complicated the rights of nature movement is thought to have the potential to mitigate climate change.
An example: the citizens of Toledo, fed up with trying to get the state and federal governments to clean up Lake Erie, voted for the Lake Erie Bill of Rights granting legal rights to a waterbody and allowing citizens to file lawsuits on behalf of the lake. This was about 2013 or so, and in 2020 it was found to be unconstitutional. But the movement continues to grow. Here’sa summary article: https://news.climate.columbia.edu/2021/04/22/rights-of-nature-lawsuits/
Anyone see this as a real possibility for change? It may be that big climate changes are coming so swiftly and dramatically that it may be too little/too late for this strategy?
A Thank You to who posted about the tree loss, your words really resonated with me to the point of having to do something even so small as a postcard-size collage.
@marigold that may have been a post of mine - where I shared my distress at the Hyundai Electric Battery plant going up just 4 miles down the road from me. There are already 3 new subdivisions going up in what was forest and fields along the river. The loss of habitat and ensuing human/animal interactions and ignorance have just devastated me. People complaining of black bear, foxes, bob cats etc being in their yards and scrounging for food - the easily adaptable ones like coyotes, raccoon ...urban opportunists and brazen with it... getting shot at and killed while killing pets etc etc. If it was my post? I thank you that it moved you to take action.
We are facing the loss of another pristine area - full of history, endangered flora and fauna and irreplaceable trees and rare wildflowers and plants as well as animals. I have been signing petitions, writing Senators, fund raising as the state has an opportunity to purchase said area - which has been a Wildlife Management Area for years.... that the owners graciously let the state use. They are offering first dibs to the state to buy...we are working hard to save it. Say a prayer that we may.... places like these? would take hundred of years to recover from development and environmental losses.
Your collage is beautiful! Y'all look up "Don't it make you want to go home" by Joe South... it says it all.
@journeywithme2 Yes, it was your post and thank you again! I put the postcard up on Instagram to spread the word. "Don't It Make You Want to Go Home" - for real. The woods, with wild pink azaleas, I used to play in as a child are now office condos. Sending very best wishes for success in preserving the pristine natural area you are working so hard to save at present.
Hi
I think it was mentioned before about problems possibly forming with the Gulf Stream affecting the Northern Hemisphere, it looks like something similar in the Southern hemisphere is happening as well. Those underwater conveyer belts moving the nutrients around the oceans slowing down or stopping could cause the breakdown of a lot of ecosystems, fish stocks, affect the weather.
We really don’t know know what we are doing to this world, what else might be happening in the background that we are ignorant of.

“We’ve already had to abandon some of the index glaciers that we used to monitor, because their snowlines and meaningful ice volume have completely disappeared.”
Not good, less melt for farming and hydro electricity etc.

“These pulses translate into sea level rise and could be really important for sea defences,” she said. The rate of loss was critical if, for example, a rise expected over 200 years could actually occur in 20 years, Batchelor said. The research could also be used to enable computer models to make better predictions about future ice loss.
Me no like this
