Letter to the Editor
I'm writing because climate change is real and demands urgent attention. The evidence is clear: global temperatures have risen about 1°C since the late 1800s; glaciers, ice sheets, and Arctic sea ice are shrinking; sea levels are rising faster as oceans warm and land ice melts; and atmospheric CO₂ has climbed from about 280 ppm before the Industrial Revolution to over 420 ppm today, largely from burning fossil fuels. Scientists also observe stronger heat waves, heavier downpours, worsening wildfire conditions, and shifts in ecosystems. Evidence from ice cores, tree rings, corals, and ocean sediments shows today’s warming is unusually rapid compared with most natural changes. Taken together, these facts lead to one conclusion: Earth is warming, and human activity is the main cause. We should listen to science and act.
