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 affects now. Many of the major roads in the Florida Keys will be underwater this year. Cities like Miami, New Orleans, Bangkok, Amsterdam, Ho Chi Minh City, and Kolkata India, are going to be submerged by 2030. The countries most exposed to rising sea levels are the United States, followed by China, India, Japan, the Netherlands, Thailand, Vietnam, and Bangladesh. In our best case scenario, we can expect a trillion dollars a year in global flood damage. And a quarter-billion people looking for new homes. If we continue to ignore the Paris Climate Accord and warm the planet 2.5 degrees Celsius, we’ll displace over a billion people. That’s 13% of the world’s urban population looking for new homes, food and jobs.



The worst case scenario is that we throw caution to the wind. That we revert to full dependence on fossil fuels and melt ALL the world’s ice. That will raise sea levels 60-70 meters (200-233 feet). But at the point, sea level may be the least of our problems.







Join host, Bob Grove, and guests to discuss How Melting Ice Sheets Are Drowning The World. Guests include:

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 accurately predicting today’s global warming issues as far back as the 1950s. And the petroleum industry spent millions of dollars to deny their own climate research and to reposition global warming as a theory, not a science-based fact. In 2022, they spent over a quarter billion dollars on U.S. media, lobbying and political campaigns to deny accepted climate science.



That’s a lot of money paying for a lot of climate disinformation. So, how do we talk about climate issues with friends and family who are constantly exposed to this disinformation? How do we understand and constructively speak truth to climate deniers?







Join host, Bob Grove, and guests to discuss the Reasons For Climate Denialism: How To Speak The Truth. Guests include:

* Jack M. Gorman MD, President and Co-Founder of Critica

CLIMATE HOUR – The study of volcanoes and rocks help scientists chart our planet’s history of warming and cooling. These studies provide quantifiable data that is accurate, objective, and results in a high degree of consensus among scientific communities. Consensus among geologists who study our planet’s rocks and the minerals and processes that shape and form them. Consensus among geomorphologists who study our planet's surface, why landscapes look the way they do, and how they evolved. And consensus among volcanologists who study the lava and magma beneath our planet’s surface.



Together, these hard sciences provide solid data that leads to testable climate science predictions. But, perhaps more importantly, the study of volcanoes and rocks give us a baseline for comparison to today’s accelerated period of climate change. And current rates of volcanic and geomorphic change may help our scientists predict and prepare us for the climate change coming down the road.







Join host, Bob Grove, and guests to discuss the study of Volcanoes and Rocks, climate’s ultimate hard science. Guests include:

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. That’s a 40% savings in EV maintenance. And our friends at the Union of Concerned Scientists report that, over the lifetime of your car, the average emissions of an EV is 28 metric tons compared to a gas vehicle’s 57 metric tons. That’s a 51% reduction in EV greenhouse gas emissions.



Electric Vehicles now cost the same as equivalent gas-powered cars, and a single charge will take you the same distance as a single tank of gas. Electric vehicles are cost-effective, healthy, and great for the planet. There’s no reason not to own one today.







Join host, Bob Grove, and guests to discuss how electric vehicles make practical sense under multiple scenarios. Guests include:




* Chris Yunker, Managing Director of Resilience, Clean Transportation and Analytics at the Hawaii State Energy Office



* David Reichmuth, Senior Scientist in the Clean Transportation Program at the Union of Concerned Scientists



* Jamie Green, Managing Consultant at Plug-in KC



* Kathy Harris, Director of Clean Vehicles at the Natural Resources Defense Council

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 grass. And the more trees you have around your house, the cooler and cleaner your air will be. So plant a tree.



Or plant a forest. Teams in India and other places around the world are growing home pocket forests with as many as 300 trees in an area the size of six parking spaces. That’s 300 trees growing in around 900 square feet. That’s a full on ecosystem in your backyard. You can plant a forest.
