Warming Lakes & Rivers = Trouble


It’s pretty easy to find climate change articles discussing the changes that are taking place in the world’s oceans. But, the gringa asks, what about the lakes and rivers of the Earth?

I grew up on a river. I love rivers. I love canoeing and floating down rivers on tubes and camping out alongside the banks of a river. What’s happening with these rivers I love? And what about lakes? Every summer we take a traditional three day weekend family trip to one of the most beautiful lakes in Texas. What’s happening to this fabulous lake? Unfortunately, the research shows that these are all changing as well.

NASA’s response to this change is to create a “global water cycle budget”. It covers a ten year period of the Earth’s freshwater concerns. This will be the baseline by which future “global water cycle budget’s” will be compared.

The water cycle involves the entire environmental process of how water moves, in all forms, around this big, blue planet. As depicted in the image posted it is easy to trace how water evaporates from the surface of the Earth. As it rises into the atmosphere it cools, condenses into clouds, then returns to the Earth as precipitation (rain, snow, hail,  or sleet). This is the kind of science the gringa learned in elementary school but it is, perhaps, the most critical environmental cycle for the continuation of life on Earth.

From the year 2000 until 2010 NASA collected satellite data  to estimate how much energy from the sun was required to move water. Hotter days means more evaporation of water within the soil. More evaporation means more moisture in the winds that transport this moisture throughout the world. Because the Earth is a closed system, any water that evaporates from its surface can be accounted for in the water vapor that eventually accumulates in the atmosphere. It’s kind of like taking a jar of pennies to the bank and getting dollars in return. It’s an even exchange of the same thing, money, but it exists in two different forms, pennies or bills. Water on Earth is the same. It’s either here on Earth as water or in the atmosphere as a form of precipitation.

However, the water model is a bit more complicated. Consider that each penny represents a different data set concerning where the water is specifically located, formed, or used. Such as: ocean, lake, evaporation from soil and plants, streams, rivers, human consumption. To help scientists manage all of this data they divide the Earth into seven land masses (Eurasia, South America, North America, Africa, Antarctica, Mainland Australia, Oceania/New Zealand/Tasmania) and nine ocean basins (North Pacific, South Pacific, Indian, North Atlantic, South Atlantic, Caribbean, Mediterranean, Arctic, Black Sea).

Over two dozen satellites provide scientists with data concerning precipitation and evaporation over the land masses and oceans. Researchers can track the movement of atmospheric water vapor, river runoff, groundwater reservoirs, soil moisture and snowpacks.

These important studies have already determined that lakes around the world are warming. This warming trend is affecting the ecosystems they are a part of as well as threatening the security of adequate freshwater supplies.

To come to the conclusion that lakes are warming, NASA used a twenty-five year compilation of data of ground measurements of over 200 lakes on six separate continents. On average, the lakes are warming about half a degree Fahrenheit every decade. Some lakes, the ones at higher latitudes, are warming even faster, one whole degree Fahrenheit per decade. That means that freshwater lakes are warming faster than the oceans.

As lakes warm, algal blooms increase. These rob the oxygen in the water from the fish. NASA’s models predict a twenty percent increase in these toxic algal blooms over the next century. Not only will this result in a chain reaction within the ecosystem wiping out the fish, as well as the wildlife and fauna that depend on those fish, but the blooms will also increase greenhouse gas emissions. Algal blooms are expected to produce methane emissions that will increase four percent over the next decade unless we Earthlings come up with a solution.

Solving the lake warming problem is a very important component of solving the climate change problem because methane emissions are 25 times more powerful than carbon emissions. A massive worldwide increase of algal blooms in freshwater lakes is a disaster we cannot allow to happen.

If the world’s lakes become a casualty of climate change, it won’t just be an environmental disaster, it will be a humanitarian disaster. These are important sources for drinking water, crop irrigation, and the production of food fish that are an important protein source for vulnerable populations around the world. Some researchers are already detecting evidence that productivity in warming lakes is already declining.

Out of the 37 largest aquifers on Earth, 21 are already past the sustainability tipping point and are being depleted. Another 13 are classified as “significantly distressed”. Eight are classified as “overstressed”. “Distressed” and “overstressed” means that these water sources have no natural replenishment to offset consumption. Five more were classified as “extremely stressed”, being depleted but with some replenishment occurring.

These were the conclusions of NASA’s study of ten years of data from the GRACE satellites. The GRACE satellites measure how Earth’s gravity is affected by existing masses of water. What NASA reports is alarming and difficult for the gringa to swallow, even with a glassful of water. That means that almost one third of our world’s groundwater is rapidly disappearing. And what’s even scarier is there is no reliable data that can predict just exactly when these wells will run dry. Yet, we continue to consume rather than conserve.

One of these overstressed reservoirs is the Arabian Aquifer System. It sustains over 60 million people. If we think there’s trouble in the Middle East right now over regional power struggles and the global fight to dominate the oilfields for profit, what the heck can we expect to see when these people have nothing left to drink? What kind of mass exodus will occur when that happens? This is a problem that must be solved. When climate change deniers scoff at the idea that climate change is the single most issue that threatens the national security of all peoples, they have no idea what they are talking about.

If Americans thought the California and Texas droughts were painful, consider what could occur in India and Pakistan, home to the second-most overstressed aquifer, the Indus Basin. Then there’s the third most overstressed water source, the Murzuk-Djado basin in north Africa. These regions are home to almost two billion people! Think about the Syrian refugee crisis. We ain’t seen nothin’ yet.

While working toward a solution, scientists cannot agree on any projected timeline of “time to depletion”. And when the gringa says they cannot agree, I’m talking about discrepancies of warnings of ten years to twenty-one THOUSAND years! However, one thing that these scientists DO agree on is that in a water-scarce society that is water dependent, this kind of ignorance is intolerable. Well, the gringa is glad to hear that.

Because groundwater reservoirs are so deep beneath the surface of the Earth, the only method to accurately measure just how much is down there is to drill, baby, drill. It’s gonna cost a lot of money, but the experts say it has to be done. NASA is committed to using its technology, personnel and data to help secure mankind’s future and improve lives around the world. By sharing knowledge freely with scientists around the world, the agency hopes to increase understanding that will lead to solutions.

The gringa waits to hear NASA’s announcement of a challenge like “Dig A Hole, Save The Planet”. The gringa has every confidence that NASA will continue to lead the charge to save us Earthlings from ourselves and the messes we continue to make. These challenges are simply a way for us to redeem ourselves after making such awful messes.

1990 Immigration and Nationality Act – It’s The Lottery, Baby!


Let’s play the lottery and see who gets to enter the country! Yes, the 1990 Immigration and Nationality Act introduced a lottery program. But, don’t be fooled. Lottery is just a fun way of saying “quota”. Quota was a bad word in the history of United States immigration policies. I guess legislators thought this was a pretty slick maneuver.

November 29, 1990, President George Bush, Sr., spoke to the nation and made these points about the bill he signed into law:

  • He respected immigrants: “… the fundamental importance and historic contributions of immigrants to our country…”
  • He appreciated the need for family unity: “… our tradition of family reunification… support for the family as the essential unit of society…”
  • He acknowledged the economic benefit of the immigrant, “… immigration of skilled individuals to meet our economic needs… cultivation of a more competitive economy… encourage the immigration of exceptionally talented people, such as scientists, engineers, and educators… promote the initiation of new business… and the investment of foreign capital in our economy…”
  • He was honest about the “bad” element among immigrants: “… swift and effective punishment for drug-related and other violent crime… aliens who, by their violent criminal acts, forfeit their right to remain in this country… jeopardize the safety and well-being of every American resident… improves this Administration’s ability to secure the U.S. border…”

Annually, the Attorney General would review statistics that had been gathered for five years from all over the country. Nations would be designated as “High Admission” or “Low Admission”.  High admission countries had at least 50,000 immigrants that had become permanent residents. Immigrant hopefuls of these nationalities would not be permitted entry unless the “lottery” was unable to be fulfilled by immigrants from the “Low Admission” nations who received preference. The purpose of this was to achieve more ethnic diversity within the United States. The gringa supposes this seems okay on the surface. Let’s dig a little deeper and see how it all works out.

These were the regions that comprised the “High Admission” and “Low Admission” zones considered in the new visa lottery system: Africa; Asia; Europe; North America (Canada and Greenland); Oceania (the geographical area including Micronesia, Fiji, all Polynesia, New Zealand, New Guinea, Melanesia, and Australia); South America; Mexico; Central America; and the Caribbean. In order for an immigrant hopeful to get a visa, not only do they have to come from a “Low Admission” country, but they also have to have a high school diploma and two years of work experience. If an immigrant hopeful was lucky enough to get a visa, their children and spouses were included. The United States considered family unity in this immigration reform policy and the gringa is happy ‘bout dat!

To get down to the specific numbers, America would issue about triple the number of visas than it did prior to the passage of this act. Most of these visas were issued to immigrants who were sponsored by employers. Guess what was required of these employers? They had to show documentation that they were unable to fill the position with an existing American citizen worker. Now, when will all these people stop griping about immigrants coming over here and stealing American jobs? It just ain’t so! Funny how the politicians know these laws exist to protect American jobs yet when an election year comes around some will campaign on headline grabbing, voter stimulating issues that are absolute lies, such as, “We’ve got to do something about immigration! Unemployment is so high and Joe Bob can’t get a job because those damn immigrants are pouring over the border and taking jobs away from good ol’ Americans!” Liar, liar, pants on fire. There are so many jobs that an humble immigrant is grateful to get paid to do that a spoiled American will turn their nose up at. That’s why most of these visas were issued!

For the first five years of this law, maximum limits were put in place. A total of 700,000 would be allowed in annually during this first five year period. Family based immigration was preferred so 465,000 visas were set aside for this type of immigrant. 55,000 visas were designated for spouses and aliens who had spouses or parents who had been legalized in the U.S. under the amnesty plan of 1986. 140,000 visas were set aside for skilled laborers to enter. 40,000 immigrants from “adversely affected” countries were given their own special group.

An example of “adversely affected” people would be the 1,000 displaced Tibetans who entered the country in 1991. On April 30, 1990, China announced the end of martial law in Tibet’s capital. For thirteen months Tibetans had suffered under military rule, harshly silenced and oppressed from any protest against the Chinese government. Military rule had existed in Tibet for decades but China cracked down in 1989 when Tibetans started getting too big for their britches and actually wanted a little freedom and independence, particularly in the area of practicing their religion, and began protesting in public. Too bad it was only 1,000 that made their way here. The gringa wishes all of them could have made it.

Did this immigration reform achieve its goal of creating more diversity in the American population? Prior to this bill, Asia and Latin America were the source nations for the majority of immigrants entering the United States. Under the provisions of this act, the American workforce was primarily supplied with Mexican and Filipino laborers. Indians, Canadians, Chinese and Africans made up the balance. Even today the Latin and Asian immigrants are the predominant ethnicities represented in the immigrant population. So it seems the goal of diversity wasn’t achieved. The most significant change was that fewer of these immigrants were poor.

However, the ethnic fabric of American medicine, science, education and sports was enriched as the result of this immigration reform. To keep these skilled workers in the country, deportation laws were relaxed as well as many stipulations that otherwise would have excluded an immigrant hopeful for qualifying for entry. One of these stipulations, which really seems to get xenophobes all worked up, is that the requirement to speak English was passed over. It makes no difference to the gringa. The gringa likes a challenge, especially a challenging conversation.

The ultimate culmination of the aftermath of this legislation is what we have today. For those who are not threatened by cultural and language differences of other people, the gringa being one those people, we shrug and say, “Who cares. Let ‘em stay as long as they’re minding their own business, working and caring for their family and community.” For the xenophobes, this is their worst nightmare. They have to suffer the indignity of pushing the number one button on their phones to select English. It’s all just so much more damn work and inconvenience that’s been created by these non-English speaking foreigners. It seems American government was socially evolving (except during campaign years when they regressed for the sake of garnering votes). Now the work is to help these hard-headed, scaredy-cat xenophobes evolve.
