12 小时之前 · As global heat records are obliterated, scientists conclude it’s a signal the planet is likely on track to breach the Paris climate agreement goal of restricting global warming to 1.5 degrees ...

2 小时之前 · However, the new studies published today in Nature Climate Change suggest even a single month or year at 1.5°C global warming may signify Earth is entering a long-term breach of that vital threshold. Global average temperature data from six organisations show 2024 was world's hottest year on record and the first to breach the 1.5°C mark. (WMO)

2025年1月26日 · Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past 100 to 200 years. Although Earth’s climate has been evolving since the dawn of geologic time, human activities since the Industrial Revolution have a growing influence over the pace and extent of climate change.

2025年1月16日 · Access to common climate maps, data, and tools. Search a dataset catalog, check the status of key environmental indicators with the Global Climate Dashboard, or browse the Data Snapshots collection to locate publication-quality images to grab and re-use.

5 天之前 · The effects of human-caused global warming are happening now, are irreversible for people alive today, and will worsen as long as humans add greenhouse gases to the atmosphere. We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves.

Jan-Sept 2024 global average temperature 1.54 (±0.13) °C above pre-industrial level; Long-term warming measured over decades remains below 1.5°C; Past 10 years are warmest on record and ocean heat rises; Antarctic sea ice second lowest on record and glacier loss accelerates; Extreme weather and climate events lead to massive economic and ...

State of Global Climate report confirms 2023 as hottest year on record by clear margin; Records broken for ocean heat, sea level rise, Antarctic sea ice loss and glacier retreat; Extreme weather undermines socio-economic development; Renewable energy transition provides hope; Cost of climate inaction is higher than cost of climate action

Tracking climate change and natural variability over time. The heating influence of all human-produced greenhouse gases was 49 percent higher in 2022 than it was in 1990. This index tracks coordinated shifts in air pressure and the jet stream between the Arctic and the mid-latitudes.
