Yes. The observed warming over the last century—especially since the mid‑20th century—is overwhelmingly driven by human activities. What’s doing the warming - Greenhouse gases from burning fossil fuels (CO2), agriculture and waste (methane), and industry/fertilizers (nitrous oxide). - Land-use changes like deforestation that reduce the planet’s ability to absorb CO2. - Some human-made aerosols co

Short answer: it’s mixed, and it depends on what you mean by “improving.” A few concrete ways the federal government has changed under President Trump (sworn in on January 20, 2025): - Civil service and agency management - A governmentwide hiring freeze and workforce‑reduction directives led to large net separations in 2025; GAO and OPM document sharp declines and new hiring rules. In 2026 OPM

Short answer: Often yes for workers, and sometimes yes for the broader economy—especially when unions and employers bargain cooperatively and rules are well designed. But effects vary by sector, how bargaining is organized, and how high union wage premiums are. What the research generally finds For workers - Wages and benefits: Union members earn about 10–20% more than comparable nonunion worker

Yes. The nationwide pro-democracy protests peaked in spring 1989, and the military crackdown in Beijing occurred on the night of June 3–4, 1989.

Short answer: Voter fraud exists but is rare in the U.S., and there’s no credible evidence of it occurring on a scale that would swing statewide or national results. Most problems people notice are due to clerical errors, bad data matches, or misunderstandings rather than deliberate fraud.

Short answer: No—cryptocurrency isn’t “safe” in the sense of low risk or capital preservation. It’s a high‑volatility, speculative asset class. That doesn’t make it bad, but it means you should only invest after understanding the risks and sizing positions appropriately. Key risks to know - Extreme price swings: 50–90% drawdowns have happened multiple times. - Regulatory risk: Rules and enforceme

Short answer: It’s not too late to avoid the worst impacts, but it is too late to “undo” all the changes we’ve already set in motion. What “reverse” can mean: - Stop it from getting worse: Achievable. If we cut greenhouse gas emissions rapidly and reach net‑zero CO2, global temperatures would largely stop rising and many impacts would stabilize. Every tenth of a degree we avoid prevents damage. -

Short answer: In several domains, yes—China poses significant risks to U.S. interests—but it’s also an indispensable economic and diplomatic counterpart. The picture is mixed and issue-specific. Where it’s a threat or high-risk - Military balance in the Indo‑Pacific: Rapid PLA modernization, coercive activity around Taiwan and in the South China Sea, and growing nuclear and missile forces raise d

Short answer: No. As of the latest data available (August 2026, released September 11, 2026), overall U.S. consumer prices were 3.4% higher than a year earlier, not lower. Grocery prices (“food at home”) were 2.2% higher year over year. Some individual categories did fall—e.g., dairy was down 0.3% and used cars were down 2.3% versus August 2025—but the overall level is higher. ([bls.gov](https://w

Short answer: yes—at population levels, high intake of ultra‑processed foods (UPFs) is a public‑health concern. Why experts say this - Consistent epidemiology: Large cohort studies and meta‑analyses link higher UPF intake with greater risks of obesity, type 2 diabetes, cardiovascular disease, depression, some cancers, and all‑cause mortality. While observational, the direction and dose–response p

Short answer: it depends which outcomes you care about and over what dates. If we look at national indicators since January 20, 2025 (when Trump took office again) through today (September 24, 2026), here’s the picture. Getting better for many households - Jobs: The labor market remains solid. In August 2026, unemployment was 4.1% and payrolls rose by 162,000; jobless claims are near multi‑month

Here are the 10 biggest stories as of today (Thursday, September 24, 2026), based on major outlets and official sources: - Trump–Xi summit in Washington: The leaders meet today amid rising AI and trade tensions; a high‑profile state dinner includes top tech CEOs (Microsoft, OpenAI, Nvidia, Apple). No major breakthroughs expected, but both sides aim to steady ties. ([apnews.com](https://apnews.com

Here are the biggest, well‑documented threats in the current U.S. political climate (as of September 24, 2026): - Deepening polarization and low trust in institutions, which make it harder to accept election outcomes and to govern. Recent surveys show persistently negative views of both parties and historically low trust in the federal government. ([pewresearch.org](https://www.pewresearch.org/po

Short answer: Yes—across their full life cycle, today’s electric vehicles (EVs) are usually better for the environment than comparable gasoline cars, and the advantage grows as the electric grid gets cleaner. The details matter, though. Here’s the balanced view. Why EVs generally win - Lower lifetime greenhouse gases: Even after accounting for battery manufacturing, most EVs emit substantially le

Short answer: No. Under international law and by most ethical standards, Russia’s 2022 invasion of Ukraine is not justified. Why: - UN Charter: Article 2(4) prohibits the use of force against the territorial integrity or political independence of any state. Russia had no UN Security Council authorization and no valid self‑defense claim against an armed attack by Ukraine. - Self-defense/preemption

Short answer: There isn’t one single “AI law.” As of September 24, 2026, systems like me are governed by a patchwork of binding laws and regulations, plus nonbinding standards and guidance. Here’s the current map and the rules that most often matter in practice. Cross‑border principles and standards (nonbinding but widely used) - OECD AI Principles (values, transparency, accountability, robustnes

Short answer: it depends—on who’s using it, how, and for how long. Social media is a powerful tool with both clear benefits and real risks. Helpful when - You use it actively to connect (messaging, groups, communities), learn, or organize. - You curate a positive, diverse feed and follow credible sources. - You keep use moderate and protect sleep and focus. - You find support you don’t get offlin

Short answer: It depends on the goals you care about (reducing homicide, suicide, mass shootings, trafficking) and how you weigh them against individual rights, culture, and constitutional limits. In the U.S., courts recognize an individual right to keep and bear arms, but allow regulations that fit within history-and-tradition and due‑process constraints. Within that space, some policies have rel

Short answer: There is no final, authoritative court ruling that Israel has committed genocide in Gaza. The question is being litigated and assessed by different bodies that have reached different interim conclusions. What the law requires - Under the Genocide Convention, genocide is any of several prohibited acts committed with the specific intent to destroy, in whole or in part, a national, eth

Short answer: More prepared than in 2019—but not “ready enough.” The U.S. has built stronger detection, coordination, and medical-countermeasure systems since COVID-19, yet persistent gaps in testing, workforce, supply chains, funding stability, and public trust could slow or fragment the next response. What’s stronger now - Faster detection and analytics: CDC’s Center for Forecasting and Outbrea

Short answer: yes—AI chatbots can be biased. Bias here means systematic tendencies that produce unfair or skewed outputs across groups, topics, or viewpoints. Why it happens - Training data: Models learn patterns (including stereotypes and imbalances) from the internet, books, code, etc. - Missing/overrepresented voices: Some languages, regions, or groups are underrepresented; others dominate. -

Short answer: It depends on your goals. A well‑designed increase on very high incomes and large fortunes can raise revenue and modestly reduce inequality with limited growth costs; a blunt hike in top brackets can backfire through avoidance and timing games. How economists think about it - Equity: Because marginal utility of income falls as income rises, many argue higher top rates improve fairne

Yes. Climate change is real, and the planet is warming primarily because of human activities—mainly burning fossil fuels and deforestation. How we know: - Temperatures: Global average surface temperature has risen by about 1.2°C (2.2°F) since the late 1800s. - Greenhouse gases: Atmospheric CO2 has climbed from ~280 ppm pre‑industrial to over 420 ppm today. - Oceans and ice: Oceans are heating up,

Short answer: We should probably have a basic income floor, but jumping straight to a large, no-strings UBI for everyone isn’t the best first move for the United States. Why a basic income floor makes sense - Cash works: Unconditional or lightly conditioned cash transfers reliably cut poverty, reduce stress, and improve health and financial stability. Effects on work are small to neutral in most

Yes. Vaccines are one of the most effective tools we have to prevent disease. Why they work - They train your immune system to recognize a germ before you encounter the real thing, creating immune “memory” that blocks infection or greatly reduces illness severity. What we’ve seen in the real world - Eradicated smallpox worldwide and pushed polio to the brink of eradication. - Huge drops in illne

Short answer: neither is inherently “safer.” Risk depends on model capability, how it’s released, and how it’s governed. Open and closed approaches trade off different kinds of risk. How open models can be safer - Transparency and scrutiny: More eyes can audit training data, alignment methods, and vulnerabilities; reproducible science improves robustness. - Vendor-independence: You can self-host

Short answer: both—and which side “wins” depends on time horizon, sector, and how quickly people, firms, and policy adapt. Near term you’ll see more job reshaping than wholesale job loss; longer term, net job creation is plausible if productivity gains translate into new products, lower prices, and higher demand. What drives job losses - Automation of routine, rules-based digital tasks: basic cus

Here’s a concise snapshot as of September 24, 2026: Who holds power - President: Donald J. Trump (47th president); Vice President: JD Vance. Republicans control both chambers of the 119th Congress: Mike Johnson is Speaker of the House, and John Thune is Senate Majority Leader. ([usa.gov](https://www.usa.gov/presidents?utmsource=openai)) What’s next - The 2026 midterms are on Tuesday, November 3,

Here’s a quick, well‑sourced briefing for Thursday, September 24, 2026 (U.S.): - Trump–Xi summit opens in Washington today (Sept 24–26). The agenda centers on trade/tech frictions, Taiwan, Iran and a proposed U.S.–China “AI hotline” to manage model failures or escalation risks. A state dinner caps day one.

Short answer: In the United States, polarization today is very high by modern standards—higher than in the mid‑20th century and roughly comparable to the late 19th century—but the Civil War/Reconstruction era was worse. What that means, broken down: - Elite (Congress/statehouses): Roll‑call and ideology measures show Democrats and Republicans are farther apart than at any time since at least the
