Top 10 High Albedo Sports Arenas | Lowering the Heat

Washington (GGM) Analysis | September 21, 2021 by author and climate journalist Noreen Wise

High albedo is a vitally important climate solution, that will not only lower indoor temperatures and curb carbon emissions, but will also help reflect the sun’s energy, making up for the decreased sun reflection of our shrinking icecaps. 

The threat of the smaller white icecaps has been highlighted in several powerful recent documentaries, one of which was A Life on Our Planet, in which Sir David Attenborough highlighted that forcers such as smaller white icecaps are now causing warming to increase at an increasing rate, which has scientists very concerned.

In light of this looming peril, and following the release of last month’s IPCC Report in which the IPCC warned that we only have 11 years to fix this, Chairwoman of the House Select Committee on the Climate CrisisKathy Castor (FL-D) was recently interviewed and stated boldly and decisively for all to understand: “It’s a call to action. It’s a call to immediate action.”

Sports arenas, as well as many convention centers and hotels in the hottest cities around the country, were developed in high albedo colors and materials, and now serve as great role models in this new era of high heat. High albedo is their rule of thumb. Too many empty seats in steaming hot arenas forced them into action. They responded to the crisis with innovative solutions that reversed the trend.

Let’s all do the same. In fact, this is what the IPCC and scientists around the globe are hoping for. That we all rush to reverse the trend with innovative solutions. 

The following is a very subjective list of the Top 10 High Albedo Sports Arenas in US. To be honest, it appears that nearly every sports arena in the world has high albedo which is a bold statement in and of itself.

The list of international high albedo sports arenas is long, but the stunning National Stadium in Singapore, with its massive white dome, is a standout.

What colors do you see when you drive through your county? In Northern Virginia, it’s plainly clear that high albedo is the rule of thumb for hotels, hospitals and large office complexes and appears to be the standard recommendation of developers of large spaces. The Pentagon, which opened its doors in 1943, is a great example of moderately high albedo in its massive complex that employs 35,000 people.

I’m thus confused about the choices made by residential developers who defy these principles and instead choose to nail down black roofs and often use darker materials on exterior walls like red brick. It’s time to turn this around.

Boosting Albedo Everywhere Is a Climate Solution

Washington (GGM) Analysis | September 19, 2021 by author and climate journalist Noreen Wise

After a summer of unprecedented weather events, with hundreds of deaths and many billions of dollars in damages, the IPCC Report released on August 8, 2021, fell on open ears. We all stopped to process the urgent warnings.

CODE RED for humanity. We must make immediate changes.  These bold and chilling declarations were blasted through the vast major media outlets worldwide, as well as thousands of podcasts, millions of private conversations, and billions of social media posts. Articles such as the one by US New and World Report in July 2021, informing us that climate change already results in an extra 5 million deaths per year, provided real time data of just how forcefully climate change is crashing down on us.

And then there were this week’s extreme weather events to drive home the point. This is how traumatic it is at only 1ºC+. But the world is currently on a trajectory of 3ºC. The IPCC recently advised that if we rush and do what’s necessary, we’ll be able to stay below 2ºC. But even 2ºC seems unendurable.

Heart of the matter. “Without the white icecaps less of the sun’s energy is reflected back out to space, and the speed of global warming increases.” —Sir David Attenborough, A Life On Our Planet

The speed of global warming increasing at an increasing rate due to the shrinking icecaps, is motivation to sprint so that we have the time to make the necessary systemic changes to our infrastructure, as well as transition individual daily household and personal behaviors to eco-friendly, sustainable and green behaviors in a circular economy.

At a symposium in London in the spring of 2009, Nobel laureate and President Obama’s Secretary of Energy at the time, Stephen Chu, boldly announced to the crowd that whitening all the roofs and pavements in the world would be the equivalent of removing all cars on the planet for 11 years.  He didn’t mean this literally of course, but rather as a powerful illustration that we’d all be able to identify with.

This cool phenomenon is known as the albedo effect. Albedo is the ability of surfaces to reflect the sun’s energy, just like the polar icecaps. Albedo is measured in increments from 0 to1, with 0 being the darkest colors that absorb the sun’s energy which become quite hot, and 1 being the the coolest colors that reflect the the sun’s energy the best and keep everything cool.

Albedo levels:

  • Black – albedo 0
  • Green grass – albedo .25
  • Desert sands – .40
  • Newly poured concrete – .55
  • White – .8
  • Metallic silver – .9
  • Perfect mirror – albedo 1

Stephen Chu emphasized the three main benefits of whitening roofs and pavements:

  • Immediately cools a building’s interior which drives down use of air conditioning.
  • Results in lower energy use, which cuts costs and lowers carbon emissions.
  • White and lighter colors reflect the sun’s energy (which will make up for lost icecaps).

Next Steps:

Stephen Chu’s urgent recommendations were made 12 years ago. Many large convention centers, sports arenas, coliseums followed through exactly as suggested and rebuilt their stadiums applying the ideal albedo colors. We have to do the same on an individual level.

  • Switch roof on our houses to white or a much lighter color, no black.
  • If your normal re-roofing is scheduled for 2 years from now, move it up and re-roof immediately.
  • Is your driveway black asphalt? Quickly transition to concrete or paint it non-reflective white.
  • From now on, go with light colored cars.
  • Form an albedo committee in your town and lobby local government to paint town parking lots white, school roofs, libraries, and all surfaces.

Good Luck! Staying below 2ºC is the most precious gift we can give our children. They’ll never forgive us if we don’t succeed at this.
