Climate Change and Health

Climate change facts are the measurable, evidence-based data points about Earth’s changing climate that urban planners use to design resilient cities and guide adaptation strategies. These facts include rising global temperatures, increased frequency of extreme weather events, sea-level projections, and shifting precipitation patterns that directly inform how communities build infrastructure, zone land, and prepare for future conditions.
For anyone looking to understand how cities respond to climate realities, the connection between data and design is where science meets action. A coastal planner uses projected sea-level rise …

California leads the nation in solar power and electric vehicles, yet coal-fired plants in distant states still power part of our grid. This contradiction isn’t about hypocrisy. It’s about infrastructure, interstate agreements, and the complex reality of how electricity actually reaches your home.
Coal energy remains one of the world’s largest electricity sources, despite aggressive renewable targets in progressive states. The fuel that powered the Industrial Revolution now accounts for roughly 16% of electricity in the Western grid that serves California, down from over 50% two decades ago. That decline represents…

Picture Earth wrapped in an invisible blanket. This blanket, made of gases like carbon dioxide and methane, keeps our planet warm enough for life to thrive. But here’s the problem: humans have been making this blanket thicker and thicker since we started burning coal, oil, and gas to power our cars, heat our homes, and run our factories. That thicker blanket traps extra heat, causing temperatures to rise around the world. This is climate change, and it’s already affecting weather patterns, ocean levels, and ecosystems in ways that touch every corner of the planet.
You’ve probably noticed extreme weather events …

Climate change isn’t some distant threat appearing in computer models. It’s unfolding right now, reshaping our world through forces we’ve set in motion. Understanding what drives these changes matters because the connection between climate change and health affects every breath we take, every meal we eat, and every community we call home.
The science is clear: human activities have fundamentally altered Earth’s climate system. Burning fossil fuels releases carbon dioxide that traps heat in our …

Every night, artificial light floods the sky above our cities, suburbs, and even rural areas. What most people don’t realize is that this glow isn’t just blocking our view of the stars. It’s fundamentally disrupting ecosystems, throwing off wildlife behavior, and contributing to broader environmental challenges that affect us all.
Light pollution has tripled in some regions since 2000, and in 2026, roughly 80% of the global population lives under light-polluted skies. This isn’t merely an aesthetic problem for astronomers. Artificial light at night interferes with natural cycles that countless species have …

Every time you spray pesticides on a lawn or farm field, those chemicals begin a journey far beyond their intended target. They seep into groundwater, drift on the wind to neighboring ecosystems, and accumulate in the tissues of insects, birds, and aquatic life. What starts as a solution to protect crops becomes a cascade of unintended consequences that ripple through entire food webs.
The numbers tell a sobering story. Research from Agriculture and Agri-Food Canada in 2025 found pesticide residues in 87% of tested waterways across agricultural regions, with concentrations frequently exceeding safety thresholds for aquatic organisms…

Canada’s federal environment minister position stands at a crossroads in June 2026, with recent ministerial transitions reshaping the country’s climate leadership at a critical moment. For young Canadians who’ve grown up with climate anxiety as a constant companion, understanding who holds this role matters less than grasping why the position itself keeps falling short of what science demands.
The minister’s office controls billions in climate funding, sets emissions regulations that touch every sector of the economy, and represents Canada in international negotiations where our credibility has taken repeated…
