Degrowth: The Path From Consumerism To Survival

Climate Hour ·

2025/09/01

CLIMATE HOUR – Sustainability is about finding life’s balance. Producing enough to satisfy your customers’ needs while earning enough to satisfy the needs of you and your co-workers. In contrast, perpetual economic growth is about a cycle of producing surplus, more than is needed, then using mass marketing to convince people to overconsume.Perpetual economic growth is based on consumerism. Convincing people to buy more than they need. More than is healthy. Fast fashion, fast food, commercial

How Melting Ice Sheets Are Drowning The World

Climate Hour ·

2025/08/01

CLIMATE HOUR – Sea level rise may be climate change’s biggest long-term impact. With just today’s 1.2 degree Celsius increase in global temperature, we can expect sea level rise of at least 1-2 meters (3.3-6.6 feet). And that’s our best case scenario. If countries continue to ignore the Paris Climate Accord and temperatures rise 2.5 degrees Celsius, we can expect the collapse of the Greenland and West Antarctic ice sheets. And that will raise sea level 10-12 meters (40 feet).We’re seeing the

2025/07/01

CLIMATE HOUR – Climate issues are clearly on everyone’s minds. The constant weather disasters, disruption of our food systems, sea level threats to coastal communities. Yet in the face of what we see every time we open our front doors, climate denialism continues to flourish. People continue to deny that the climate is changing or that our lifestyle choices are contributing to that change.And there’s plenty of disinformation to help the deniers. Scientists in the oil & gas industry were

CLIMATE HOUR – Today’s electric vehicles out-perform gas vehicles on every front. A study at Michigan's Transportation Research Institute found that the average cost to operate an EV in the U.S. was $485 per year, compared to an average cost of $1,117 to operate a gas vehicle. That’s a 56% savings in EV operating costs. A U.S. Department of Energy study found that scheduled maintenance on an average EV costs 6.1 cents per mile compared to a cost of 10.1 cents per mile for an average gas vehicle

How To Make Trees Fight Climate Change

Climate Hour ·

2025/04/01

CLIMATE HOUR – You can make trees. You can plant them, watch them grow, and they will automatically fight climate change for you. Trees are made out of cellulose and cellulose is carbon. There are literally six atoms of carbon in every molecule of cellulose. And all of the carbon going into trees come out of the air. So make a tree, and that tree will fight climate change for you.Trees look good. They smell wonderful and they produce fruit and nuts. Planting trees is certainly easier than mowing

2025/02/02

CLIMATE HOUR – Prospering may sound like it has financial overtones, but there’s more to it than that. A prosperous life is one filled with joy and love; full of friends and community. We’re prosperous when we have our health and can enjoy fresh air & water. Prosperity is measured by the wealth of our daily activities and not by the balance of our bank account.Scientists started blowing whistles about climate change in the 1980s. That’s over half-a-century ago, far too long ago to avoid or stop

2025/01/01

CLIMATE HOUR – Many people are experiencing climate-related disasters on a regular basis. This can lead to climate anxiety; a type of emotional anxiety which may express itself as distress about future climate disasters, or even distress over the long-term existence of humanity and the survival of our friends and family.Worry about climate is not the same as climate anxiety. We all need to be worried about climate issues. This is a healthy response to real problems. But when worry becomes

The Case for Climate Optimism and Green Energy Law

Climate Hour ·

2024/12/01

CLIMATE HOUR – Current political trends are making it harder and harder to express climate optimism. Not only are countries failing to meet their Paris Climate Treaty commitments, but recent elections have given climate deniers control of many governments. The prospect for significant climate action through legislation is dimming. But the potential for economic solutions to climate change are growing. Electricity produced from renewable wind and solar is now cheaper than that from fossil fuels. The

CLIMATE HOUR – What is the role of state government in the challenge of Climate Change? The scientific consensus is that global warming of over two degrees Celsius will threaten human life as we know it. The Paris Agreement defines 1.5 degrees as a more desirable goal to limit the worst outcomes. Yet as of October, 2023, the planet’s average surface-temperature increase was already 1.4 degrees Celsius.There’s many things we can do to reduce our personal carbon footprint. But we also need to

2024/05/01

CLIMATE HOUR – A little community orchard provides an amazing number of benefits. First there’s basic carbon sequestration. Trees take carbon out of the air and reduce global warming. Then there’s food sovereignty. Trees give you control of your own food sources. In today’s corporate farming system, genetically modified foods are picked green, irradiated to prevent spoilage, then shipped half way around the world to high priced grocery stores. Food sovereignty means growing tasty, nutritious food
