Today’s episode features a conversation with Dr. Stephanie Roe, WWF’s Global Climate and Energy Lead Scientist. Stephanie explains the role that climate change plays in driving heat waves, what key indicators she’s following to determine just how bad heat-related climate impacts have gotten, and what we can all do in our daily lives to address climate change and adapt to extreme heat.

I cannot imagine being at all hopeful that emissions will peak anytime in the next 2 decades.

here in Oregon the USFS is CLEAR CUTTING millions of acres of public forest due to fear of fires! and the heavy equipment they use is also tearing up the soils! Recovery of those forest won't happen in my life!

Jevons' paradox. Increased energy efficiency will result in more energy consumption, not less.

Over 40 years ago the late great Carl Sagan warned us against tipping into a "Runaway Greenhouse". From what I see it looks like we did that beginning last July, and the evidence mounts daily showing that is likely. Maybe it's time to dig Sagan out of the memory hole. When Hansen spoke to Congress in 1988 he was mostly just telling the same story that Sagan told Congress in 1985! It's on Youtube...

We talk allot about what "we" are emitting, as we should. Here's the problem as I see it. The CO2 that "we" are emitting has warmed the planet enough to start melting permafrost, which acts like a cork on a bottle. Under permafrost is centuries worth of detritus material which when thawed will decay and send those gases into the atmosphere in a reinforcing feedback loop. In other words: "the more ice we melt the faster we melt ice". I hope I am wrong but if this occurs we are in for some very bad times.

Good report and appreciate it. However, CO2 removal from the atmosphere (an additional 5-7 billion tons per year) is a joke. People making better food choices, another joke. Politicians changing policy fast enough to make a dent in fossil fuel use, really? When equatorial zones become uninhabitable and billions of people migrate north and south, then, maybe, the population of people will get the idea that radical changes need to happen.

Greed has finally caught up with our species and humanity is going to pay the ultimate price

The aerosol masking paradox makes abundantly clear that there is no way out of this situation!

Nothing you can do.... Grow a damn forest garden!!!!

It's time to start building underground housing.

The climate crisis is an existential threat, but it is just one of many facing us and life on Earth. Our human population is still exploding and our cities are still gobbling up farmland and wildland. Twelve billion people won’t leave any habitat for other species. We are are still overexploiting increasingly scarce ground and surface water. Scarcity and demand are driving up prices for fossil fuel and fertilizer, key inputs for agriculture. And, wildlife populations are rapidly declining and going extinct. We are already using more resources than our planet can sustainably provide to us. As our population rapidly grows from immigration in the US and Europe, and too many births elsewhere, and as the climate veers further from what our agricultural systems can adapt to, mass starvation will increase.

Soylent Green, watch it.

Hanssen hypothesizes that sulfate cooling effects, and as a result, CO2 heating effects may both be underestimated in IPCC climate models. Since 2010 sulfate output is reduced. A few extra years of accelerated warming are needed to confirm the hypothesis of much stronger warming vulnerability of CO2.

Here in the US Midwest we’re hitting a stunningly LOW number of summer record highs. We’re still burning lots of coal and have high SO2 levels. Columbus OH # of 100F+ days from 1931-1955: 31. Number of 100F days from 1956- 1980: Zero. Coal plants started going into service around 1950. India also has high SO2 and per Goddard climate reports it is not warming nearly as fast as planet average. Scaling up renewables will mean much hotter summers in the Midwest. No more aerosol masking and we’ll obliterate records.

This video should have millions of views.

The reason we have climate changes is the same reason nothing much will be done to mitigate climate change. The rush for profit and progress has driven climate change. The people who've achieved great success want to continue doing all the things they have gotten used to doing. Which means more profits, more tech progress and more climate change.
-
Our climate and environment issues are beyond human fixing. Why ? Because we humans have something called " greed and selfishness" and those issues require team work which governments and individuals are not willing to do so. Maybe in word but in reality.

We're already in uncharted territory . The 1st CO2 molecule for the industrial era went up I750. It won't come down for another 730 years. We are the frogs in the pot of water.

Great talk. Former and plant ecologist here, and resource manager for various entities. In retirement, I run a construction and travel business. My ideas differ from yours a bit, but mostly agree with you. I’m concerned about the climate crisis because it is currently costing me and my construction and lodging business at least $50,000 in direct costs (higher food, air conditioning, electricity, insurance costs); lost business due to fire and smoke; mitigation including using more fire resistant siding and other materials, etc. And, thousands of people in North America and hundreds of thousands of us humans throughout the world, who who used to think our regions were safe from fire and flooding, are losing our homes now! Today! As I type! Human overpopulation is the primary driver of the climate crisis, increasing food and water scarcity, mass extinctions of wildlife, increasing global conflict, etc. If we ignore overpopulation, no point in wasting time and money addressing the climate crisis. I am infinitely skeptical of carbon removal. The promise of it does nothing more than justifying the continued sale and profit from fossil fuels by the Saudis, Russia, Excon, the US, etc. Then there is increased migration which is causing riots in Britain today, and the election of fascist strongmen like Trump in Europe and North America. We now think that the Syrian civil war was caused by climate impacts to farmland. Water and food shortages, the deaths of the natural systems that sustain us, are the result of human overpopulation and rapid climate change. We need to stop burning stuff. Yesterday. If we act now, we will save more of our natural world and our civilization. Individual actions are good but insignificant compared to societal-scale actions. Ok, good work you two. Keep speaking out.

Thank god the "new Ice age" was prevented in the 1970's. I used to lay in bed worring about freezing to death by 1982,
