TL;DR: The impact of this El Nino Southern Oscillation (ENSO) event can be gauged by the number of popular articles in international magazines and journals dealing with the agricultural, social and economic implications of the phenomenon as discussed by the authors.

TL;DR: In this article, the authors found that recent changes in the means and variability of the North Atlantic Oscillation (NAO) index are related to an increasing trend in the Greenland Blocking Index (GBI, high pressure over Greenland) in summer and a more variable GBI in December.

TL;DR: In this article, the Southern Oscillation Index (SOI) was extended by using an index of Jakarta rainday counts back to 1829, with a gap between 1861 and 1865.

TL;DR: In 2017, the dominant greenhouse gases released into Earth's atmosphere-carbon dioxide, methane, and nitrous oxide-reached new record highs. as mentioned in this paper The annual global average carbon dioxide concentration at Earth's surface for 2017 was 405.0 ± 0.1 ppm, 2.2 ppm greater than for 2016 and the highest in the modern atmospheric measurement record and in ice core records dating back as far as 800 000 years.

TL;DR: The International Surface Pressure Databank (ISPD) as mentioned in this paper is the largest collection of global surface and sea-level pressure observations and has been used for various general climate and weather studies.
