Journal ArticleDOI
Observed fingerprint of a weakening Atlantic Ocean overturning circulation
Levke Caesar,Levke Caesar,Stefan Rahmstorf,Stefan Rahmstorf,Alexander Robinson,Georg Feulner,Vincent S. Saba +6 more
TL;DR: A characteristic ‘fingerprint’ of sea-surface temperatures suggests that the Atlantic overturning circulation has slowed substantially since the mid-twentieth century, as predicted by climate models in response to increasing carbon dioxide emissions.
Journal ArticleDOI
Network-based identification and characterization of teleconnections on different scales
Ankit Agarwal,Ankit Agarwal,Levke Caesar,Levke Caesar,Norbert Marwan,R. Maheswaran,R. Maheswaran,Bruno Merz,Jürgen Kurths,Jürgen Kurths,Jürgen Kurths +10 more
TL;DR: This study characterizes the interactions between the cells of a global SST data set at different temporal and spatial scales using climate networks that investigate the correlation between the SST time series at a range of scales allowing instantaneously deeper insights into the correlation patterns compared to traditional methods like empirical orthogonal functions or classical correlation analysis.
Journal ArticleDOI
Unravelling the spatial diversity of Indian precipitation teleconnections via a non-linear multi-scale approach
Jürgen Kurths,Ankit Agarwal,Roopam Shukla,Norbert Marwan,Maheswaran Rathinasamy,Levke Caesar,Levke Caesar,Raghavan Krishnan,Bruno Merz +8 more
TL;DR: In this paper, a non-linear, multiscale approach based on wavelets and event synchronization is proposed for unravelling teleconnection influences on rainfall in the Indian subcontinent.
Journal ArticleDOI
Current Atlantic Meridional Overturning Circulation weakest in last millennium
Levke Caesar,Levke Caesar,Gerard McCarthy,David Thornalley,Niamh Cahill,Stefan Rahmstorf,Stefan Rahmstorf +6 more
TL;DR: The Atlantic Meridional Overturning Circulation (AMOC) is one of Earth's major ocean circulation systems and has a major impact on climate and has been observed to be weaker than it has been for the last millennium.
Journal ArticleDOI
An Overview of Ocean Climate Change Indicators: Sea Surface Temperature, Ocean Heat Content, Ocean pH, Dissolved Oxygen Concentration, Arctic Sea Ice Extent, Thickness and Volume, Sea Level and Strength of the AMOC (Atlantic Meridional Overturning Circulation)

TL;DR: In this paper, the global ocean physical and chemical trends are reviewed using seven key ocean climate change indicators: (i) Sea Surface Temperature, (ii) Ocean Heat Content, (iii) Ocean pH, (iv) Dissolved Oxygen concentration, (v) Arctic Sea Ice extent, thickness and volume (vi) Sea Level and (vii) the strength of the Atlantic Meridional Overturning Circulation (AMOC).
