跨政府氣候變化委員會作出警告:儘管人類擁有工具及專業知識,但並未走上限制全球暖化的正確軌道
人類尚未在應對全球暖化方面走上正軌,但我們確實掌握了答案。在正確的領導下,全世界可以避免遭受危險的氣候變化。在剛剛發佈的聯合國氣候科學小組報告中,跨政府氣候變化委員會強調了這個關鍵訊息。
of global investors see climate change as a key theme in their portfolios by 2025-2026
Climate change has become increasingly important to investors’ investment policies, and this is set to continue. In our 2024 Global Climate Survey, 77% of all investors surveyed said they expected the issue to be central to, or a significant part of, their investment policy in the years up to 2026, up from 62% making such a commitment today.
The survey shows that Asia-Pacific investors have overtaken their counterparts in Europe in making it a priority in 2024, with 79% now doing so. Europe is projected to gain back the baton in two years’ time, with 89% forecasting that it will be central to investment strategy.
Globally, the average figures took a slight knock due to declining interest in North America, following a backlash against ESG investing amid the energy crisis of 2022-2023 in which fossil fuel use rose. Enthusiasm there, though, it set to rise again over the coming two years to more than half of North American investors.

This chart from the World Resources Institute using data from the IPCC 2023 report makes for sober reading. Global warming is causing records to be broken every single day, and it will only get worse while emissions are still rising.

These two charts show how much damage has been done over the last two centuries. While the industrial period effectively began with the advent of steam power in the 1780s, reliable data only goes back to 1850, which is now used for analysis.
The first chart shows how global surface temperatures have increased to at least 1.1 degrees above pre-industrial levels, creating the warmest multi-century period in more than 100,000 years.
NASA’s own research puts the level of global warming even higher, at 1.17 degrees in 2023 than the long-term average for the time of year, and up to 1.36 degrees in total since the industrial era.

The second shows how greenhouse gas concentration levels are now at their highest levels since prehistoric times. Since emissions are still rising, these concentrations are expected to increase.
