Your Questions About Climate Change—Answered

Earlier this month, readers sent a flood of questions about the science, the politics, and the everyday impacts of climate change. Somini Sengupta, our international climate reporter, took the opportunity to address them live from COP30 in Brazil, where world leaders, activists, and scientists gathered to chart the next decade of climate action.

What’s the most urgent scientific finding from COP30?

“The data are crystal‑clear,” Somini said. “Global temperatures are on track to exceed 1.5°C above pre‑industrial levels within the next few years unless we dramatically cut emissions.” She highlighted a new IPCC report released at the summit, which underscores the shrinking window for limiting warming to 1.5°C.

How are political leaders responding?

“There’s a mix of optimism and hesitation,” she noted. “While several countries announced more ambitious targets, others remain stuck on outdated fossil‑fuel subsidies.” Somini pointed to Brazil’s pledge to achieve net‑zero emissions by 2050 as a notable step forward.

What can ordinary people do right now?

“Every action counts,” Somini emphasized. “Start by reducing personal energy use, supporting renewable‑energy projects, and demanding climate‑friendly policies from your representatives.” She encouraged readers to join local climate groups and stay informed through reliable sources.

Why is COP30 different from previous conferences?

“The focus has shifted from promises to implementation,” Somini explained. “We’re seeing concrete financing mechanisms for green infrastructure and stronger accountability measures for nations that miss their targets.” She praised the new Global Climate Finance Tracker, which will monitor how pledged funds are actually spent.
