China Is Leading the World in the Clean Energy Transition. The country spends like no one else on renewables and has reshaped the global market. Xi Jinping gives a video address at the United Nations Climate Summit. Speaking by video at the UN Climate Summit in New York last week, China's president Xi Jinping laid out his country's climate ambitions. While the stated goals may not have been aggressive as some environmentalists would like, Xi at least reaffirmed China's green commitment.

Time is running short to limit global warming to 1.5 C (2.7 F) above preindustrial levels, but there are feasible and effective solutions on the table, according to a new UN climate report. Despite decades of warnings from scientists, global greenhouse-gas emissions are still climbing, hitting a record high in 2022. If humanity wants to limit the worst effects of climate change, annual greenhouse-gas emissions will need to be cut by nearly half between now and 2030, according to the report. That will be complicated and expensive. But it is nonetheless doable, and the UN listed a number of specific ways we can achieve it.

Tackling climate change is one of the greatest challenges facing humanity. Over the next decade, the technologies of the Fourth Industrial Revolution (4IR) – particularly 5G, the Internet of Things (IoT) and artificial intelligence (AI) – will provide essential tools for increasing efficiency in the economy and preparing for a post-fossil fuel society. Last year, the Intergovernmental Panel on Climate Change delivered its special report on the effects of global warming of 1.5 C and above. The report clearly lays out the difference between 1.5 C and 2 C warming and emphasizes the urgent need to avoid crossing tipping points in Earth's life support systems. To give us a chance to limit global warming to this level, global greenhouse gas emissions must peak by 2020 and then fall by half every decade, corresponding to 7% annual reductions as a global average.
