The US and Mexico share a common history in many areas, including language and culture. They face ecological changes due to the increased frequency and severity of droughts and rising energy demands; trends that entail economic costs for both nations and major implications for human wellbeing. We describe an ongoing effort by the Environment Working Group (EWG), created by The University of California’s UC-Mexico initiative in 2015, to promote binational research, teaching, and outreach collaborations on the implications of climate change for Mexico and California. We synthesize current knowledge about the most pressing issues related to climate change in the US-Mexico border region and provide examples of cross-border discoveries and research initiatives, highlighting the need to move forward in six broad rubrics. This and similar binational cooperation efforts can lead to improved living standards, generate a collaborative mindset among participating universities, and create an international network to address urgent sustainability challenges affecting both countries.

美国和墨西哥在许多地区都有共同的历史，包括语言和文化。由于干旱的频率和严重性以及能源需求的增加，它们面临着生态变化。趋势给两国带来经济损失，并给人类福祉带来重大影响。我们描述了由加利福尼亚大学UC-Mexico计划于2015年创建的环境工作组（EWG）正在进行的一项工作，旨在促进两国间在气候变化对墨西哥和加利福尼亚州的影响方面的研究，教学和外展合作。我们综合了有关美墨边境地区与气候变化相关的最紧迫问题的最新知识，并提供了跨境发现和研究计划的示例，强调了在六大主题上前进的必要性。
