There are two numbers you need to know about climate change. The first is 51 billion. The other is zero. Fifty-one billion is how many tons of greenhouse gases the world typically adds to the atmosphere every year. This is where we are today. Zero is what we need to aim for. To stop the warming and avoid the worst effects of climate change, humans need to stop adding greenhouse gases to the atmosphere. This sounds difficult, because it will be. Every country will need to change its ways. Virtually every activity in modern life – growing things, making things, getting around from place to place – involves releasing greenhouse gases, and as time goes on, more people will be living this modern lifestyle. That’s good, because it means their lives are getting better. Yet if nothing else changes, the world will keep producing greenhouse gases, climate change will keep getting worse, and the impact on humans will be catastrophic. But “if nothing else changes” is a big If. I believe that things can change. We already have some of the tools we need, and as for those we don’t yet have, we can not only invent, but also deploy them, and, if we act fast enough, avoid a climate catastrophe. Two decades ago, I would never have predicted that one day I would be talking in public about climate change. My background is in software, not climate science. Things changed for me when I met with two former Microsoft colleagues who were starting non-profits focused on energy and climate. They brought along two climate experts who were well versed in the issues, and the four of them showed me the data connecting greenhouse gas emissions to climate change. I kept learning everything I could about climate and energy, agriculture, oceans, sea levels, glaciers, power lines, and more. One thing that became clear to me was that our current sources of renewable energy – wind and solar, mostly – could make a big dent in the problem, but we weren’t doing enough to deploy them. It also became clear why, on their own, they aren’t enough to get us all the way to zero. The wind doesn’t always blow and the sun doesn’t always shine. Within a few years, I had become convinced of three things: 1. To avoid a climate disaster, we have to get to zero. 2. We need to deploy the tools we already have, like solar and wind, faster and smarter. 3. We need to create breakthrough technologies that can take us the rest of the way.Not long ago, I grabbed breakfast at a hotel in southern Spain. The only cereal available was a local version of frosted corn flakes, so I readied myself to enjoy a bowl of my childhood favorite. But my sweet indulgence wasn't what I'd expected: The cereal milk was heated — apparently standard in this part of Spain — and my poor frosted flakes immediately turned to mush. Not so grrrrrrreat. Soggy flakes or not, I find breakfast to be a fun part of my travel day, especially because the experience varies so much from one country's breakfast table to the next. The farther north you go in Europe, the heartier the breakfasts. The heaviest is the traditional British "fry." Also known as a "Plate of Cardiac Arrest," the fry is a fundamental part of the bed-and-breakfast experience, and is generally included in your room price. A standard fry comes with cereal or porridge, a fried egg, Canadian-style bacon or sausage (and sometimes mackerel or haggis), a grilled tomato, sautéed mushrooms, baked beans, and fried bread or toast. This protein-stuffed meal can tide me over until dinner. You'll quickly figure out which parts of the fry you like. Your host will likely ask you up front which breakfast items you actually like, rather than serve you the whole shebang and risk having to throw out uneaten food. The Scandinavian breakfasts buffet is the perennial favorite for the "most food on the table" award. It pays to take advantage of breakfast smorgasbords when you can. For about $20 (a cheap meal in these parts), you can dig into an all-you-can-eat extravaganza of fresh bread, cheeses, yogurt, cereal, boiled eggs, herring, cold cuts, and coffee or tea. In place of cereal and milk, Scandinavians like to pour thick yogurt over their granola. Throughout the Netherlands, Belgium, Germany, Austria, Switzerland, and most points east of there, expect a more modest buffet — but still plenty of options (rolls, bread, jam, cold cuts, cheeses, fruit, yogurt, and cereal). In these countries, there's a good chance of finding hard-boiled eggs, but scrambled or fried eggs are relatively rare. In Poland, track down jajecznica, the local wake-up call of eggs scrambled with kielbasa sausage, served with a side of potato pancakes. The breakfast of choice in Russia is oladi, pancakes perfectly fried to be crisp on the outside but soft in the middle, then topped with sour cream, honey, or berries. Germans have an endearing habit of greeting others in the breakfast room with a slow and dour "Morgen" ("Morning" — short for "good morning"), though they have plenty to be happy about. Breakfast is usually included, and offers hearty fuel for the day: ham, eggs, cheese, bread, rolls, and pots of coffee. In Switzerland, don't miss an opportunity to try Bircher Muesli, a healthful mix of oats, nuts, yogurt, and fruit that tastes far more delicious than it looks. If breakfast is optional, take a walk to the nearest bakery — every German, Austrian, and Swiss town has at least a few bakeries offering a world of enticing varieties of bread and pastries, baked fresh every morning. As you move south and west (France, Italy, Spain, and Portugal), skimpier "continental" breakfasts are the norm. You'll mostly likely get a roll with marmalade or jam, occasionally a slice of ham or cheese, and coffee or tea. The good news? These little breakfasts compel you to sample regional favorites: In Spain, look for chocolate con churros (fritters served with a thick, warm chocolate drink), pan con tomate (a toasted baguette rubbed with fresh garlic and ripe tomato), or a tortilla española (a hearty slice of potato omelet). Italian breakfasts are particularly tiny, but the delicious red orange juice you get is made from Sicilian blood oranges. And you can buy a delightful toasted sandwich from a corner bar anywhere, anytime in Italy to make up for the minuscule breakfast. In France, locals just grab a warm croissant and coffee on the way to work. Queue up with the French and consider the yummy options: croissants studded with raisins, packed with crushed almonds, or filled with chocolate or cream. If you expect breakfast to be too sparse, plan ahead to supplement it with a piece of fruit and a wrapped chunk of cheese from a local market. Being a juice man, I keep a liter box of OJ in my room for a morning eye-opener. Coffee drinkers know that breakfast is the only cheap time to caffeinate yourself. Some hotels will serve you a bottomless cup of a rich brew only with breakfast. After that, the cups acquire bottoms and refills will cost you. Juice is generally available at breakfast, but in Mediterranean countries, you have to ask…and you'll probably be charged. In many countries, breakfast is included in your hotel bill, though if you make prior arrangements with the hotelier, you may be able to skip breakfast and pay a lower price for the room. If breakfast costs extra, it's often optional, and you can usually save money and gain atmosphere by buying coffee and a roll or croissant at the café down the street or by brunching picnic-style in the park. When deciding whether to request breakfast, consider your timing; if you need to get an early start, skip the breakfast — few hotel breakfasts are worth waiting around for. Come to the European breakfast table with an adventurous spirit. I'm a big-breakfast traditionalist at home, but when I feel the urge for an American breakfast in Europe, I beat it to death with a hard roll. Can you make 5 questions based on the textSure!

Photosystem II (PSII) – Light Absorption & Water Splitting • Light energy (photons) excites electrons in chlorophyll molecules. • These high-energy electrons leave PSII and are passed into the electron transport chain (ETC). • Meanwhile, water molecules are split (photolysis) into: o O₂ (released as a by-product into the atmosphere) o H⁺ ions (protons, which build up inside the thylakoid) o Electrons (e⁻), which replace the ones lost by PSII. 2. Electron Transport Chain (ETC) • Excited electrons move through protein carriers embedded in the thylakoid membrane. • As they move, their energy pumps H⁺ ions into the thylakoid space, creating a proton gradient (high H⁺ inside, low outside). 3. ATP Production (ATP Synthase) • The buildup of H⁺ ions acts like a “waterfall” of potential energy. • These protons flow back across the membrane through ATP synthase, a protein complex that acts like a turbine. • This flow drives the conversion of ADP + Pi → ATP, which provides energy for the Calvin cycle. 4. Photosystem I (PSI) • Electrons arriving from the ETC enter PSI. • Sunlight excites them again, boosting them to a higher energy level. 5. NADPH Production • The energized electrons are transferred to NADP⁺. • Along with a proton (H⁺), this forms NADPH, another energy carrier. • NADPH is then delivered to the Calvin cycle to help build glucose. End Products of Light-Dependent Reactions: • ATP (energy source for Calvin cycle) • NADPH (reducing power for glucose synthesis) • O₂ (released into the atmosphere as waste) Light-Independent Reactions (Calvin Cycle) • These reactions do not directly require sunlight. • They occur in the stroma of the chloroplast (the fluid-filled space surrounding the thylakoids). • The inputs are ATP and NADPH (from light-dependent reactions) and CO₂ (from the atmosphere). • The outputs are glucose (C₆H₁₂O₆) and other carbohydrates. Think of the Calvin cycle as a factory that uses the energy and “raw materials” made in Stage I (ATP & NADPH) to build sugars. The 3 Main Steps of the Calvin Cycle 1. Carbon Fixation • CO₂ from the atmosphere enters the chloroplast and diffuses into the stroma. • Each CO₂ molecule attaches to a 5-carbon sugar called RuBP (ribulose-1,5-bisphosphate). • This reaction is catalyzed by the enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase — the most abundant enzyme on Earth!). • The result is a short-lived 6-carbon compound, which immediately splits into two 3-carbon molecules called 3-PGA (3-phosphoglycerate). Summary: CO₂ + RuBP → 2 × 3-PGA 2. Reduction Phase • The 3-PGA molecules are “energized” and converted into G3P (glyceraldehyde-3-phosphate), a more energy-rich 3-carbon sugar. • This transformation requires: o ATP (provides energy) o NADPH (provides high-energy electrons and hydrogen atoms). • Some of the G3P molecules will eventually be combined to form glucose and other sugars. Summary: 3-PGA + ATP + NADPH → G3P 3. Regeneration of RuBP • Not all G3P molecules leave the cycle. Most of them are used to regenerate RuBP so the cycle can continue. • This regeneration also requires ATP. • For every 3 turns of the cycle, 5 G3P molecules are recycled to regenerate 3 molecules of RuBP. Summary: G3P + ATP → RuBP The Full Cycle Balance • To make one G3P molecule that can exit the cycle (and later form glucose), the cycle must run 3 times, fixing 3 molecules of CO₂. • To make one glucose molecule (C₆H₁₂O₆), the cycle must run 6 times (since glucose needs 6 carbon atoms). Inputs (for 1 glucose): • 6 CO₂ • 18 ATP • 12 NADPH Outputs: • 1 glucose (C₆H₁₂O₆) • 18 ADP + 18 Pi • 12 NADP⁺ Day vs Night Clarification • The Calvin Cycle is called light-independent, but that doesn’t mean it only happens at night. • It usually happens during the day because it depends on ATP and NADPH, which are only produced in light-dependent reactions (when sunlight is available). Simplified Analogy • Carbon fixation = The factory brings in CO₂ as raw material. • Reduction = Workers use energy (ATP & NADPH) to shape the raw material into useful products (G3P). • Regeneration = Some products are recycled to keep the factory running (RuBP is re-formed). • Output = After enough cycles, the factory produces glucose, the “food” of the plant.I110.31.b.17.C Topic: Reading/Vocabulary Development
