Reading
Read the article carefully. Hover over the highlighted words to see a short hint.
Scientists have been warning us about climate change for decades, and yet the Earth seems determined to prove them right ahead of schedule. The planet's average temperature has risen by approximately 1.2 degrees Celsius since the pre-industrial era, a shift that sounds modest until you consider what it has already triggered. Glaciers are retreating, sea levels are creeping upward, and weather patterns that communities relied upon for centuries have become increasingly unpredictable. The culprit, according to an overwhelming scientific consensusgeneral agreement, is the accumulationgradual build-up of greenhousetraps heat in atmosphere gases, primarily carbon dioxide and methane released through human activity.
The consequences of this warming are not confinedlimited to one place to polar bears and distant ice caps. Extreme weather events have intensifiedbecome stronger dramatically over the past two decades, with hurricanes, droughts, and wildfires occurring with a frequency and ferocityextreme violence or force that meteorologistsweather scientists find deeply concerning. Coastal cities from Miami to Mumbai are investing heavily in flood defences, while agricultural regions across Africa and South Asia are grapplingstruggling to deal with with shifting rainfall patterns that threaten food securityreliable supply of food for hundreds of millions of people. Climate change, it turns out, is less a future problem and more a present emergency that is quietly, and sometimes loudly, reshaping life across the globe.
The political response to this crisis has been, to put it diplomaticallycarefully, avoiding offence, complicated. International agreements such as the Paris Accord have established ambitious targets for reducing emissionsgases released into air, but progress has been uneven at best. Wealthy nations have historically been the largest emitters, yet developing countries often bear the most severe consequences, a disparityunfair difference that has fuelled significant tension in global climate negotiations. Meanwhile, the fossil fuel industry has spent considerable resources lobbyinginfluencing politicians against the rapid transitionchange from one to another to renewable energy sources.
Despite these obstacles, a genuine shift is underway. Renewablenaturally replenished energy energy capacity has expanded at a remarkable pace, with solar and wind power now competing economically with coal and gas in many markets. Electric vehicles are being adopted in increasing numbers, and reforestationreplanting trees in an area projects are being launched on every inhabited continent. Younger generations, in particular, have pushed climate action firmly onto the political agendalist of topics to act on, refusing to accept the argument that economic growth and environmental responsibility are mutually exclusiveunable to coexist.
For language learners, the climate debate offers a fascinating window into how English is used to persuade, inform, and inspire. The vocabulary of climate science, from emissionsgases released into air to resilienceability to recover, appears constantly in newspapers, podcasts, and political speeches you will encounter as your English improves. Engaging with this topic does not just build vocabulary. It connects you to one of the definingmost important, shaping conversations of our time, one in which your voice, in any language, genuinely matters.
