“如果我们现在采取行动，我们仍然可以为所有人确保一个宜居、可持续的未来，”主席李会成在政府间气候变化专门委员会(IPCC)最新报告的发布会上说。
这份报告由世界顶尖的气候专家撰写，为大幅削减排放和修复已经造成的损害指明了一条清晰的道路。但这需要各国政府参与进来，毫不拖延地为其提供资金。
这份综合报告汇集了有关我们这个变暖的星球的所有最新科学。
它表明，尽管挑战的规模空前，但有许多减少温室气体排放的解决方案。最重要的是，我们现在就可以使用它们。
2018年，IPCC让世界意识到将全球变暖控制在1.5°C这一前所未有的挑战。五年后，随着温室气体排放量的持续上升，这一挑战变得更加严峻。
迄今为止所采取的行动的速度和规模还不足以应对气候变化。
IPCC主席Hoesung Lee补充说，综合报告“强调了采取更有雄心的行动的紧迫性”。
1. 我们没有时间可以浪费了
科学家表示，一个多世纪以来化石燃料的燃烧以及土地和能源使用的不平等导致全球变暖1.1摄氏度。它导致了更加频繁和强烈的极端天气事件，影响了世界各地的人们。
随着地球变暖，这些危险迅速升级。我们看到了更强的降雨，更强烈的热浪和其他极端天气。
联合国秘书长António古特雷斯在报告发布会上说:“人类如履薄冰，而这冰正在迅速融化。”
他说，它详细说明了人类如何对过去200年几乎所有的全球变暖负责。
“气候定时炸弹正在滴答作响。但今天IPCC的报告是如何拆除气候定时炸弹的指南，”他说。

这份报告还将损失和破坏列为重点。报告说，气候变化将继续对最脆弱的人群和生态系统造成尤其严重的打击。
损失和损害是指气候变化对人类社会和自然环境造成的负面后果。气候变化是COP27会议的一个重要议题，会议达成了一项突破性协议，建立了一个基金来应对这些后果，特别是对脆弱国家而言。
《综合报告》的93位作者之一Aditi Mukherji说:“气候正义至关重要，因为那些对气候变化贡献最小的国家正受到不成比例的影响。”
她补充说，世界上几乎一半的人口生活在极易受到气候变化影响的地区。在过去十年中，这些地区洪水、干旱和风暴造成的死亡人数增加了15倍。
Accelerated action on adaptation will be required to close the gap between the measures we currently have and what is needed.
3. UN Secretary-General uses Oscar-winning film to make his point
The UN Secretary-General told the press conference at the launch of the report that the world needs climate action on all fronts. He referenced a recent Oscar-winning film calling for "everything everywhere all at once".
Guterres has proposed that the G20 come together for something called the Climate Solidarity Pact. This agreement would see all big emitters make an extra effort to cut emissions. Wealthy countries are called upon to give funds to help emerging economies keep the 1.5C target alive.
He said that countries need to hit the "fast forward button" on their net zero deadlines.
"Specifically, leaders of developed countries must commit to reaching net zero as close as possible to 2040, the limit they should all aim to respect," Guterres said.
"This can be done. Some have already set a target as early as 2035."
Guterres' Acceleration Agenda also includes actions like:
Phasing out coal by 2040 at the latest Net zero electricity generation by 2035 for developed countries No more oil and gas licenses
"Every country must be part of the solution," he said.
"Demanding others move first only ensures that humanity comes last."
4. There is a clear way forward for climate resilience
The IPCC says that the solution lies in resilient development - finding ways to adapt to climate change or reduce greenhouse gas emissions that provide wider benefits.
"The greatest gains in wellbeing could come from prioritising climate risk reduction for low-income and marginalised communities, including people living in informal settlements," says Christopher Trisos, one of the report's authors.
"Accelerated climate action will only come about if there is a many-fold increase in finance. Insufficient and misaligned finance is holding back progress."
To be effective, the scientists say, these choices need to be rooted in our diverse values, world views and knowledge around the globe - including Indigenous knowledge. It would mean that these solutions are locally appropriate and socially acceptable.
5. The money is there but it needs to be spent on the right solutions
We have the money we need to invest in rapidly reducing greenhouse gas emissions - if current barriers are removed, the IPCC says.
These barriers include information sharing, making finance available to those who need it and general international cooperation.
Governments are essential in bringing down these barriers as they can encourage investors and hand out public funding.
"Transformational changes are more likely to succeed where there is trust, where everyone works together to prioritise risk reduction, and where benefits and burdens are shared equitably," Lee said.
Tried and tested policies which deliver deep emissions cuts and climate resilience need to be scaled up, according to the report. We need to share technology and know-how while making funding readily available.
"We live in a diverse world in which everyone has different responsibilities and different opportunities to bring about change," Lee adds.
"Some can do a lot while others will need support to help them manage the change."
