I am a child of Sputnik, the satellite launched by the Soviet Union in 1957. That event created opportunities for me to escape the horrors of apartheid by emigrating from South Africa to the United States. There, fortuitously, I was given excellent opportunities to explore how an interplay between the waves and currents influences climate variability, from interannual El Niño events to millennial ice ages. During my career, I also witnessed intriguing facets of the interactions between the profoundly different worlds of science and of human affairs. Up to 1957, El Niño was welcomed as a blessing, but by 1982 it had become a curse—not because it changed, but because our human activities are making us vulnerable to natural climate variability. We have learned to cope admirably with the occasional failures of the Indian monsoons; the resultant famines are not as calamitous as they once were. What guidance does that limited success provide for a response to global warming, a climate change we humans are inducing? This article briefly summarizes how my career as a geoscientist brought me to the conclusion that a strategy to promote responsible stewardship of planet Earth should be based on love rather than fear. We can only love what we know, so warnings of imminent gloom and doom should be complemented with efforts to make everyone aware of the wonders of our amazing planet—the only one in the universe known to be habitable.

我是 1957 年苏联发射的卫星 Sputnik 的孩子。那次事件为我创造了机会，让我从南非移民到美国，逃离种族隔离的恐怖。在那里，我很幸运地获得了绝佳的机会来探索波浪和洋流之间的相互作用如何影响气候变异，从一年一度的厄尔尼诺事件到千年冰河时代。在我的职业生涯中，我还目睹了科学和人类事务截然不同的世界之间互动的有趣方面。直到 1957 年，厄尔尼诺现象一直被视为一种祝福，但到 1982 年，它已经成为一种诅咒——不是因为它发生了变化，而是因为我们的人类活动使我们容易受到自然气候变化的影响。我们已经学会了令人钦佩地应对印度季风偶尔的失败;由此产生的饥荒不像以前那样灾难性。这种有限的成功为应对全球变暖（我们人类正在引发的气候变化）提供了什么指导？本文简要总结了我作为地球科学家的职业生涯如何使我得出结论，即促进负责任地管理地球的战略应该基于爱而不是恐惧。我们只能热爱我们所知道的，因此，在发出即将到来的阴霾和厄运的警告时，应该努力让每个人都意识到我们这个神奇星球的奇迹——宇宙中唯一已知的宜居星球。
