Over the past five million years, global mean temperatures have cooled by 3-4 degrees C. Yet, present reconstructions of sea surface temperatures indicate that temperature in the warm pools has remained stable during this time. This stability has been used to suggest that tropical sea surface ...

over the past few decades. The surface waters of the California Current warmed 1.2–1.6°C between 1951 and 1993; this warming was accompanied by a 70% decline in zooplankton abundance29, possibly because of increased surface temperatures reducing the upwelling of cold, nutrient-rich waters to ...
Modelled atmospheric temperatures and global sea levels over the past million years Climate ups and downs The climate has passed through a series of glacials and interglacials over the past million years, but the nature of this cyclicity (in terms of temperature, ice volume and sea level), and...
AntarcticaNASA image showing locations on Antarctica where temperatures had increased between 1959 and 2009. Red represents areas where temperatures had increased the most over the period, particularly in West Antarctica, while dark blue represents areas with a lesser degree of warming. Temperature change...
The early Eocene hothouse experienced highly elevated atmospheric CO2 levels and multiple transient global warming events, so-called hyperthermals. The deep ocean constitutes an assumed setting to estimate past global mean temperatures. However, availabl
(3)D.标题归纳题.根据文章第一段,In the last 50 years, sea surface temperatures around Antarctica have risen by 1-2℃, which is more than twice the global average.在过去的50年里,南极洲周围的海面温度上升了1-2℃,是全球平均温度的两倍多.后文就对南极洲温度上升所产生的生态问题进行了说明,温度...
The relationship between Indian summer (June-September) monsoon rainfall and sea surface temperatures around northern Australia-Indonesia has been explored using data from 1949 to 1991. Warm sea surface temperatures are generally associated with a good monsoon; a poor monsoon is usually accompanied and...
Based on a recent study published in the journal Science, sea surface temperatures today are comparable with sea surface temperatures around 129,000 to 116,000 years ago. That period is known as the last interglacial period (one of the warmest periods in
Increasing ENSO variability18,19,20 would intensify primarily wind-driven fluctuations of the tropical Pacific thermocline, upper-ocean temperatures, and sea level12,13,29. Yet, the future sea level is projected to become more variable interannually in many regions that are not directly affected by...
