In The Power of Carbon Dioxide, geologist Iain Stewart explores how volcanoes play a vital role in releasing carbon dioxide, a gas that helps trap heat and keeps Earth warm enough for life. Without it, our planet would be a frozen wasteland, but too much of it can cause rapid climate changes. Scientists are now studying Siberia, one of the coldest places on the planet, to understand how melting permafrost could be a predictor of Earth’s future climate. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Why Acidic Seas Spell Trouble, geologist Iain Stewart explores how global warming is shaking up life in the ocean. In Palau, an ocean scientist shares the story of millions of golden jellyfish that vanished when the water’s temperature rose by a few degrees. Plus, learn how rising carbon dioxide is making the ocean more acidic, threatening coral reefs and the marine life that depends on them. The ocean is changing fast, and scientists are racing to understand what’s next for our planet's underwater world! This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Phytoplankton, the Life-Giving Force Beneath the Waves, geologist Iain Stewart explains how oceans are vital to life on Earth, especially because of tiny phytoplankton which produce 50% of the oxygen we breathe! These microscopic organisms feed sea creatures and help turn sunlight and carbon dioxide into energy. Oceans also have a vast network of currents that connect all the seas, proven when 29,000 rubber ducks drifted across the world, showing how these currents link every ocean. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In The Survival Strategies of Bedbugs, host Harith Iskander dives into the fascinating survival strategies of Cimex Lectularius, commonly known as bedbugs. These tiny insects, about the size of an apple seed, rely on human blood to reproduce and are highly attuned to their environment. With an excellent sense of smell, bedbugs can detect over 100 compounds found in human skin and are drawn to carbon dioxide and even dirty laundry. This video is excerpted from BBC’s Got Science? a science magazine series that explores and explains science in everyday life.
In Why CO₂ Is Crucial for Our Planet's Survival, geologist Iain Stewart explains how carbon dioxide is essential for life on Earth. Without enough, planets like Mars are freezing cold, while Venus is scorching hot because it has too much. Early volcanoes released carbon dioxide that helped keep the planet warm enough for life to evolve. Yet, scientists have discovered evidence of a catastrophic "Snowball Earth" event 700 million years ago, where the planet may have been completely frozen, as shown by mysterious drop stones found in Namibia. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Climate Change and the Use of Fossil Fuels, scientists explain how human use of fossil fuels has caused Earth’s temperature to rise steadily over the last 100 years. The video explores the role of increasing carbon dioxide levels in the atmosphere and how this has led to climate change and extreme weather events. This video is excerpted from BBC’s Climate Change — The Facts, a documentary that delves into the science of climate change and its far-reaching consequences.
In Deforestation and Palm Oil see how satellite imaging has revealed a surprising amount of forest removal across the globe. Much of the deforestation is driven by the demand for palm oil, which is found in many products. Deforestation reduces the number of plants that absorb carbon dioxide emissions and adds to the emissions through burning forests. This video is excerpted from BBC’s Climate Change — The Facts, a documentary that delves into the science of climate change and its far-reaching consequences.
Discover the amazing hunting techniques of cave glow worms, witness the transformation of lake fly midges, and delve into the mysteries of bioluminescence in the jungle night. Prepare for a close-up look at the miniature marvels all around us!
In Why Mosquitoes Bite, host Harith Iskander explains why female mosquitoes are uniquely attracted to humans and why they need to consume blood to reproduce. Learn how mosquitoes require protein from blood to support their reproductive process, and how, interestingly, they tend to prefer people with blood type O. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
