The world is full of stuff and many parts of the world are drowning in it. Except for those parts of the world where people don’t have any stuff at all. Nothing to speak of.
Within our family, we stopped giving stuff as gifts quite some time ago. Nowadays, we mark occasions such as birthdays, anniversaries and significant celebrations with the gift of time.
The planet has plenty of time to spare, even though humanity does not. In a few hundred years, or a thousand years, even if mankind has pursued its current illusion of prosperity to oblivion, the planet will sedately roll on, and prosper without us. Just as it prospered long after the last dinosaur ceased to exist.
When Isaac Watts wrote his hymn, based on the 90th Psalm, he was not thinking of humanity’s self-induced annihilation as he composed the following lines.
Time like an ever rolling stream, bears all its sons away
They fly forgotten as a dream, dies at the opening day.
For those ‘successful’ busy people who have no time at all to spare, here’s a suggestion for a gift of stuff that’s actually a gift to the planet and buys us time. This gift has the added benefit of helping people who don’t have much stuff at all. Here’s a link to an Impact Calculator from Solar Aid. With enough gifts like these, perhaps one day we can sit down with Gaia and have the last laugh together.
The Climate Action Tracker posts regular progress reports on how well various countries are doing to adhere to the Paris Agreements. It tracks emissions from 32 selected countries and the list of the good, the bad, and the ugly is quite surprising even to this seasoned watcher.
Only two countries are on track to fulfil the Paris goal, of limiting emissions to keep global temperatures from rising above 1.5 degrees C; Gambia and Morocco.
The second best choice made in Paris was, if not 1.5 degrees, then at the least 2 degrees C. Just 5 of 32 countries meet this target. Bhutan, Costa Rica, Ethiopia, India and Philippines. All of the remaining 25 countries fall into the category of emitters that will lead to a world of 3 degrees warming or more. See the original list here.
Of course this predicator of doom and gloom relies only on official government policies. The reality on the ground may be a bit different in many of the countries on the list. For example, despite their governments, a few cities, power companies and private individuals already find it cheaper to produce unsubsidised renewable energy, a trend that will speed up, just a cell phone sales did in developing country markets worldwide.

Continuing the series on breaking news that deserves a bigger audience, here’s Bill Gates with a few facts about the world of today.
Today, more people are living healthy, productive lives than ever before. This good news may come as a surprise, but there is plenty of evidence for it. Since the early 1990s, global child mortality has been cut in half. There have been massive reductions in cases of tuberculosis, malaria, and HIV/AIDS. The incidence of polio has decreased by 99 percent, bringing the world to the verge of eradicating a major infectious disease, a feat humanity has accomplished only once before, with smallpox. The proportion of the world’s population in extreme poverty, defined by the World Bank as living on less than $1.90 per day, has fallen from 35 percent to about 11 percent.

Ever wanted to go on an ocean liner? Cruise ship advertisements idealise the high life to be had on the high seas. What they never say is how much ships pollute. The average ship runs on low grade oil, which can be likened to a sludge that emits more particulate matter than a million cars; more sulfur than seven million cars. And that’s just one cruise liner!
Several Scandinavian ferries now run on hybrid diesel-electric systems but, as in most advances in electric propulsion these days, China is taking the lead, as a cargo ship with a 2.4 MWh battery pack launches in Guangdong. Ironically, the ship will be used to transport dirty coal!
Car makers have a problem. They don’t admit it yet. Or maybe they do admit it to themselves, although not in public. Why should they, when enough people are buying bigger cars? Global car sales in 2017 were close to 90 million vehicles in all categories, including SUVs and light trucks. That’s roughly 1 car for every 77 people. Less than 1% of these were electric. How many more cars do we need? Car companies are powerful entities that are in the business of selling dreams; dreams of freedom, of the joy of the open road, dreams of independence. The irony is that as we buy into the dream, we destroy the very foundation on which our dreams are based.

February 2018 will mark five years after my retirement from IIASA. These five years have been full of new experiences, travel and writing. My wife and I have also attempted during this time to modify our lifestyle to be as carbon neutral as possible. Measures include living without a car, using a bicycle for shopping and public transport for travel where possible. Trips by air are unavoidable in the lifestyle we’ve chosen, and we’ve attempted to offset this carbon by buying solar panels for a farm school in India and a solar farm in Austria, 8 KW in all. These panels will apparently offset around 8 tons annually, but there’s still more to be done.
I first heard about sea level rise in a talk by paleo-climatologist Herbert Flohn at IIASA sometime in the late 1970s. At that time, many of the information requests that the IIASA library received were about global effects of a nuclear winter in the aftermath of nuclear war. Research themes changed quickly; interest moving to carbon dioxide emissions from fossils fuels, global warming, acid rain and stratospheric ozone.
In the intervening years, the reality of human-induced global warming has been accepted by all but the most ideologically blinkered societies worldwide. Travelling through parts of rural India soon after retirement in 2013, I saw repeated instances of people taking actions to adapt to climate change; water harvesting to compensate for unprecedented droughts, reforestation efforts; introduction of organic farming methods and drought resistant crops. I’d like to think that much of the credit for these adaptation and mitigation actions goes to studies by IIASA and other research institutions worldwide; scientific studies whose results filtered down over decades through the media and drew attention to these problems early on. There’s no way to prove this, and some of the water harvesting systems I saw were really ancient structures brought back into use. See more about that here
Efforts in 2015 and 2016 to help establish a rural education and vocation center failed for a very positive reason. The five acres of land (2 hectares) that had been donated to us for school use by a well-wisher is worth approximately € 300,000 (€65,000 per acre at today’s prices). The donated property was fertile agricultural land and classified as such. The local administrative authorities refused permission to reclassify the plot for use as a school and insisted that the land remain in use for agriculture. This was a positive outcome, because one of our reasons for this choice of location of a school was to prevent displacement of the rural population by expensive housing projects that would only benefit urbanites.
However the effort was not wasted. Since then our local partners have decided to build an organic farm on the land and use the experience gained to encourage the farming practices of communities in neighbouring villages. One function of this farm would be to develop markets for organic produce. We discovered several small companies in the area that offer free midday meals to their workers. They were happy to find a local supply of good vegetables. One enterprising factory owner offered his workers three free meals a day, sourcing all the vegetables from his own backyard. The vegetables he showed us were grown in plastic tubs lined with mats made of nutrient-rich hemp fibers. In fact, the method is so successful that he gives away growing kits free to any of his workers who want one for their own families’ use.
An encounter in early 2017 with a conservationist who runs a hatchery for Olive Ridley turtles on the sea coast near Chennai city led me to Tiruvannamalai, a town 200 km to the south-west. Here is an organic farm school where text-book sustainable living is practiced in the most lively and joyous manner possible. There are around 100 children in the school, ranging in age from 8 to 18. The links below will give an idea of activities at the school.
In addition to organic farming, environmental conservation and education, the school also works with villagers in the surrounding countryside, reforesting the hill that dominates the temple town, planting around 15,000 trees a year. The school’s efforts inspired us (myself and a few friends in India) to help them become energy self-sufficient, adding 5 KW of solar panels to the three they already had. Together with battery backup, the school is now completely independent of the grid. (photo attached).
This activity led me to a thought. If IIASA’s work ultimately inspired these kinds of sustainability acts, what about IIASA’s own carbon footprint? IIASA’s alumni are scattered all over the world. What if we joined together, wherever we are, and worked to offset IIASA’s carbon emissions? Such actions would benefit our own communities, wherever we may happen to live. To kick-start this effort, I’ve decided to fund the planting of 1000 trees in 2018 through the farm school mentioned above. If each tree sequesters 25 kilos of carbon (as a rule of thumb, regardless of species), this would offset 25 tons of the Institute’s annual carbon emissions.
Should this be a formal organized effort? Readers’ suggestion welcomed here. All we would need is a virtual platform where one can document one’s own efforts and have a running tally. Ultimately the goal is to achieve carbon neutrality, not only for the Institute, but also for the communities in which each one of us lives. But, as for so many initiatives, IIASA could be a starting point.
On a personal note, the years since retirement have been very fulfilling. Thanks to my wife’s job, we were able to spend 2 idyllic years on an island paradise near Hong Kong. This provided background material for a work of fiction, Grace in the South China Sea. There are two sequels in the pipeline (The Trees of Ta Prohm, and Heartwood), to appear in 2018. Look for the earlier books and announcements on the Amazon author page here.

A recent article in a Salzburg newspaper talked about the bleak future for winter sports in Austria. As snow becomes ever scarcer on the lower slopes of alpine regions, those communities that rely on income from winter tourism are looking around for alternatives to keep their economies going. Ski trails are increasingly carpeted with artificial snow that serves the purpose but cannot compete with the magic delight of snowflakes from heaven. A custom that has gained traction in recent years is snow farming. In effect, the practice is very simple. Snow is piled up during winter months in convenient natural depressions called snow depots and covered with a mix of wood chips and sawdust. The depot is then blanketed with a white covering that further insulates the reserve and preserves up to 80% of the snow through the summer months. The heat of evaporation from the moistened wood chips actually helps cool the bulk of the snow reserve. Austrian snow harvesting programs are for the benefit of the tourism business, but in the high altitudes of Himalayan Ladakh, engineers and environmentalists are creating artificial ice stupas and glaciers as a survival mechanism to provide water for village communities in the spring and summer months.
When religious leaders step outside their core business of spiritual leadership and meddle in secular affairs, then perhaps they should take their cue from the Tibetan monk in the video above. True religion should promote harmony, protect nature and improve livelihoods instead of preaching. As can be seen from the video above, reverence naturally follows.
