Climate update

 According to a report by the BBC:

"It's now "virtually certain" that 2023 will be the hottest year on record. That's something that no major climate science body expected at the start of the year."

We will be looking to COP28 to lead to some serious action...

Acts of kindness

 I saw this article online at the Guardian. Can we come up with a list for here in Guyana? 

The article lists acts of kindness which can be done (in the UK) to show kindness to another.

To quote the article:

"But what all these acts have in common is that they will make you feel good: research shows that being kind make us happier. So you can help others and feel better yourself all at once."

Examples that work anywhere:

Be polite, cheerful and friendly.

Give blood.

Being kind to animals.

Hope Wind Farm 2022

 This project seems to be moving forward. As it is a ground-breaking project it seems that things will move slowly. According to a report by OilNOW:

"Guyana is now closer to launching its first major initiative in renewable energy. The Environmental Protection Agency (EPA) recently granted approval for construction of the US$45M Hope Wind Farm Project. This represents the first substantial utility-scale renewable energy initiative to be implemented in the new oil producing South American country.

According to project documents, the 25.2MW wind farm will generate over 80GWh per year, to be delivered to the Guyana Power and Light (GPL)’s grid according to the terms of a Power Purchase Agreement (PPA) and Grid Interconnection Agreement. This wind energy therefore represents over 10% of GPL’s gross total electricity generation, enough to supply 7000 homes with power."

Another article appeared in the Guyana Chronicle. 

We look forward to GPL getting a PPA agreed.

Climate change crisis reports

As the crisis deepens three news items caught my attention.

Levels of HFCs rising - The threat from atmospheric HFCs (hydrofluorocarbons) were supposed to have been banished due to international action taken from 2005. However the threat has returned according to a report in Phys.org:
Despite reports that global emissions of the potent greenhouse gas hydrofluorocarbon (HFC) were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values.

Call for reduced investment in fossil fuels world-wide - According to the BBC:
The world will face irreversible heating unless firms shift their priorities soon, the outgoing head of the Bank of England has told the BBC.
Mark Carney said the financial sector had begun to curb investment in fossil fuels – but far too slowly.
He said leading pension fund analysis "is that if you add up the policies of all of companies out there, they are consistent with warming of 3.7-3.8C".
Of course Mark Carney is not alone in this view. Some investors are moving in this direction.


How we can meet our climate goals - An article at ScienceAlert reports on research on those "elements most likely to help society limit global warming".
According to the research, the social tipping interventions that could help us do this would be:
  • removing fossil-fuel subsidies and incentivising decentralised energy generation;
  • building carbon-neutral cities;
  • divesting from assets linked to fossil fuels;
  • revealing the moral implications of fossil fuels;
  • strengthening climate education and engagement; and
  • disclosing information on greenhouse gas emissions.
Of course, many of these mechanisms are already in process and evident in society to some degree, but whether any have yet reached a tipping point leading to a rapid societal transformation is debatable.

Atmospheric carbon dioxide hits another high

... as explained in this BBC report:

"Atmospheric concentrations of carbon dioxide and other greenhouse gases once again reached new highs in 2018.
The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade."

The fact that this just keeps going up and up really shows how far we have to go to take it seriously. Slowing the rise is not good enough. Stopping the rise is not. We to get it going DOWN and fast. Even then it will takes years to really make a difference. It seems not to be lack of knowledge but of political will or due to deliberate blindness.

Next 18 months crucial for action on climate change

A BBC report points this out noting that a key meeting takes place in late 2020 - COP26. Action is needed before then. Time is running out.

"The climate math is brutally clear: While the world can't be healed within the next few years, it may be fatally wounded by negligence until 2020," said Hans Joachim Schellnhuber, founder and now director emeritus of the Potsdam Climate Institute.
The sense that the end of next year is the last chance saloon for climate change is becoming clearer all the time.
"I am firmly of the view that the next 18 months will decide our ability to keep climate change to survivable levels and to restore nature to the equilibrium we need for our survival," said Prince Charles, speaking at a reception for Commonwealth foreign ministers recently.
"One of the understated headlines in last year's IPCC report was that global emissions of carbon dioxide must peak by 2020 to keep the planet below 1.5C.
Current plans are nowhere near strong enough to keep temperatures below the so-called safe limit. Right now, we are heading towards 3C of heating by 2100 not 1.5."

It is too late to stop climate change - it's happening already - but we must act to reduce its ferocity.

BBC looks at Guyana

Our oil prospects seem to have attracted attention this month. One report starts:
"South America's second poorest nation is bracing for an oil boom that could catapult it to the top of the continent's rich list - and beyond. But can Guyana avoid the so-called oil curse and ensure that its newfound riches benefit all Guyanese?"

This links to an Assignment report (podcast):
"Guyana - bracing for the oil boom"

Meanwhile some are urging caution in the light of changing future prospects of fossil fuels. An article in Stabroek News by Melinda Janki warns:
"Even if the present economics of oil added up (and they clearly don’t) the urgent need to halt global warming means oil will cease to be viable within a few years."
There is general agreement that there will be a time of 'peak oil' after which world demand will drop. Some say it will occur around 2025, other not til 2030s or 2040s. If we wish to curb global warming we had better wish for an early date.

The huge cost of global warming in 2018

Global warming is with us and costing us dearly. A report by Christian Aid, as reported by the BBC, counts the cost.
"The charity's report identified ten events that cost more than $1bn each, with four costing more than $7bn each.
Scientists have shown that the chances of heat waves in Europe were influenced directly by human-related warming.
Other events, say the authors, are due to shifts in weather patterns, said to be a consequence of climate change.
According to the report the most financially costly disasters linked to rising temperatures were Hurricanes Florence and Michael, with costs said to be around $17bn for the former, and $15bn for the latter."

Declining fertility

For many decades the rising human population of our planet has been regarded as a major threat to civilisation, often featured in books and movies. It now becomes clearer that fertility is actually declining in more and more developed countries such as North America, Europe and Japan.

According to a BBC report (my emphasis):
In 1950, women were having an average of 4.7 children in their lifetime. The fertility rate all but halved to 2.4 children per woman by last year.
But that masks huge variation between nations.
The fertility rate in Niger, west Africa, is 7.1, but in the Mediterranean island of Cyprus women are having one child, on average.
In the UK, the rate is 1.7, similar to most Western European countries.
If the rate is below 2.1 then the population will start to shrink. In some countries the population may be maintained only by increasing life expectancy and immigration each of which have other issues. This finding has huge implications for the future.

Plastic roads

Several countries such as India, Netherlands and Scotland, are experimenting with using recycled plastic to construct roads. One such approach is described in this BBC report.

What is a green economy?

The government is aiming for a green economy (see this report) but what is a green economy? It would seem that it is difficult to define easily in practical terms.

According to Wikipedia:
'The green economy is defined as an economy that aims at reducing environmental risks and ecological scarcities, and that aims for sustainable development without degrading the environment. It is closely related with ecological economics, but has a more politically applied focus.'
It is said to include:
Renewable energy
Green buildings
Sustainable transport
Water management
Waste management
Land management
And regarding energy (and of special interest to us in Guyana):
"Green economies require green energy generation based on renewable energy to replace fossil fuels as well as energy conservation and efficient energy use."
So we have a long way to go in the energy sector.

Guyana and climate change - Jan 2017

Some recent developments reported locally:

Integrated approach to tackle climate change (Guyana Chronicle)
"The need for closer collaboration between agencies here in addressing climate change was raised on Thursday as the Caribbean Community Climate Change Centre (CCCCC) and the United States Agency for International Development (USAID) commenced a two-day stakeholder engagement in Georgetown.
..provision will be made through the Climate Change Adaptation Programme (CCAP), which will be implemented in several Caribbean countries, including Guyana."

Guyana to participate in Climate Change & ACTO Meetings (GINA)
"Guyana will participate in fourth board meeting of Japan Caribbean Climate Change Partnership Project (JCCCP) at the invitation of the United Nations Development Programme (UNDP) which will be held in Jamaica from February 1- 2 2017."

So why is climate change so important to Guyana? We need to pay more attention to this issue so here are a few things which come to mind:
- it is causing sea-level rise which will become a critical issue for obvious reasons, eventually much of our best farm land will be lost plus our capital
- the slowly rising temperature will have very serious effects in the future, agriculture will have to adapt
- there is a global shift away from using oil which has important implications
- we need to shift our energy sector (and transportation) away from fossil fuels to hydro and solar.

Solar roofs

The US company Tesla, famous for electric cars, has announced glass roofing tiles which are also solar panels. According to this article in Bloomberg:

"If Musk’s claims prove true, this could be a real turning point in the evolution of solar power. The rooftop shingles he unveiled just a few weeks ago are something to behold: They’re made of textured glass and are virtually indistinguishable from high-end roofing products. They also transform light into power for your home and your electric car. "

While they are not cheap they are tough, light-weight and long-lasting. It looks a very promising product. Hopefully other companies will come out with competing products soon and such tiles will become available in Guyana in a few years. Being light-weight is important as it reduces shipping costs and is also better for the kind of houses built here.

Guyana's Energy Sector

Just came across this useful review of Guyana's energy sector in Kaieteur News. It is definitely incomplete but there is a problem getting documentation in many areas.

There have been many solar panels put in place in the hinterland but how many are still functional and in use is a question. A learning experience.

There are plans to increase hydropower but not yet on the scale needed. The future of the Amaila hydropower project is still being considered.

A useful page is that at the Caricom Energy Program which has links to further resources.
The GEA has a Strategic Plan for 2014-2017 on its web site - more on this later.

The role of technology in a climate solution

An interesting item in Bulletin of the Atomic Scientists advocates large reductions in energy use:
"For civilization to continue sustainably, human beings must shift from fossil fuels to solar energy—despite the technical problems. And investments are needed in biotic and other low-energy innovations. But in the end, global energy consumption must be reduced by something on the order of 60 percent. This will require a number of profound non-technological changes. Energy equity must be established among the world's nations—people in wealthy countries should not, as they do today, use hundreds of times as much energy as people in the poorest countries."

Hydro-power for Guyana?

A panel discussion on the topic was recently held, sponsored by the EU and occasioned by the visit of a delegation in regarding preparations for the 2015 Paris Climate Conference, COP21.

Reports were seen at Demerara Waves and Guyana Times.

The experts on the panel differed regarding the urgency of using hydro-power but were agreed on the need to do so.

It seems to me that hydro-power is a resource we absolutely must make use of whether multiple small installations or several large ones. It should have been done decades ago - a start was made but not followed up. It takes years for any such project to be planned, funded and built. It is not rocket science and there is abundant expertise available. We need to get over our political infighting, work together and do some long-term planning.

In the short-term we need to continue expanding the use of other alternatives such as bio-fuel and solar.

World Bank climate change MOOC

This is called 'Turn Down the Heat: Why a 4°C Warmer World Must be Avoided' and is being hosted by Coursera. It is being well-presented by a selection of experts in the usual Coursera format.  It is not a difficult course especially if you are familiar with the topic. Plenty of discussion. Recommended.

I am still hoping to see more Caribbean participants - only a small handful so far.

Civilisation is advancing!

It seems that, despite the impression made by the media, the world is getting to be a better place. This very interesting report in Slate says:
"The only sound way to appraise the state of the world is to count. How many violent acts has the world seen compared with the number of opportunities? And is that number going up or down? As Bill Clinton likes to say, “Follow the trend lines, not the headlines.” We will see that the trend lines are more encouraging than a news junkie would guess."
After examining the statistics the report concludes:
"The world is not falling apart. The kinds of violence to which most people are vulnerable—homicide, rape, battering, child abuse—have been in steady decline in most of the world. Autocracy is giving way to democracy. Wars between states—by far the most destructive of all conflicts—are all but obsolete. The increase in the number and deadliness of civil wars since 2010 is circumscribed, puny in comparison with the decline that preceded it, and unlikely to escalate."

Intergovernmental Panel on Climate Change (IPCC) report 2014


It is way past time to get serious. Governments need to act together in the interest of mankind. According to a BBC news item:
"The world needs a Plan B on climate change because politicians are failing to reduce carbon emissions, according to a UN report.
It warns governments if they overshoot their short-term carbon targets they will have to cut CO2 even faster in the second half of the century to keep climate change manageable"

And the Washington Post reports:
"At a meeting in Berlin, the U.N. Intergovernmental Panel on Climate Change (IPCC) on Sunday released a report that found that nations still have a chance to fulfill the goal but must aggressively turn away from relying largely on fossil fuels such as coal for energy and replace them with cleaner energy sources such as solar and wind power. To reach their target of 3.6 degrees (2 degrees Celsius) over preindustrial levels, nations must work together to lower emissions 'by 40 to 70 percent' of what they were in 2010, the report said."

A sustainable future?


A BBC news item on a recently released UN report entitled "Resilient People, Resilient Planet: A Future Worth Choosing " from the UN High-Level Panel on Global Sustainability reviews the report in some detail. Summarising it comments:

"Growing inequality, environmental decline and "teetering" economies mean the world must change the way it does business, a UN report concludes."

There are many recommendations (56), many of which are straight forward. Here are a few that stood out to the writer and looked relevant to us:


  • "Governments should accelerate the implementation of commitments to advance gender equality and women’s rights, including through the repeal of discriminatory laws and removal of formal barriers, the reform of institutions and the development and adoption of innovative measures to address informal and cultural practices that act as barriers.
  • Government and non-governmental entities should promote the concept of sustainable development and sustainable consumption, and these should be integrated into curricula of primary and secondary education.
  • Governments should work with appropriate stakeholders to provide citizens, especially those in remote areas, with access to technologies, including universal telecommunications and broadband networks, by 2025.
  • Measures should be taken to strengthen the interface between policymaking and science in order to facilitate informed political decision-making on sustainable development issues. Representatives of the scientific community could be included as members or advisers in relevant national or local bodies dealing with sustainable development issues."


And another noteworthy report, reported in a Wired news item, is the report "Towards a Circular Economy" by the Ellen MacArthur Foundation.

According to the news item:
"As the report states: "The essence of the circular economy lies in designing goods to facilitate disassembly and re-use, and structuring business models so manufacturers can reap rewards from collecting and refurbishing, remanufacturing, or redistributing products they make.""

Makes sooo much sense.
