Tech billionaires and climate data show mixed signals for global progress
Reports from Nature highlight how US tech philanthropists are shifting science funding while UN data indicates global emissions have slowed but remain insufficient to meet Paris Agreement targets.

Philanthropy shifts toward high-risk projects
Ultra-wealthy research investors in the United States increasingly support higher-risk projects that are personally relevant. These private funding sources often attach fewer strings than government agencies but lack strict oversight. Many programs encourage the use of technology that the donors themselves helped develop.
Emissions plateau without major cuts
Global greenhouse-gas emissions might have plateaued last year according to the latest United Nations report. Renewable energy capacity has expanded faster than expected, yet this growth is not enough to prevent temperature rises. Scientists estimate warming could peak between 2.6 °C and 2.8 °C this century under current policies.
