Using multichannel singular spectrum analysis (MSSA) we decomposed climatic time series into principal components, and compared them with Earth rotation parameters. The global warming trends were initially subtracted. Similar quasi 60 and 20 year periodic oscillations have been found in the global mean Earth temperature anomaly (HadCRUT4) and global mean sea level (GMSL). Similar cycles were also found in Earth rotation variation. Over the last 160 years multi-decadal change of Earth's rotation velocity is correlated with the 60-year temperature anomaly, and Chandler wobble envelope reproduces the form of the 60-year oscillation noticed in GMSL. The quasi 20-year oscillation observed in GMSL is correlated with the Chandler wobble excitation. So, we assume that Earth's rotation and climate indexes are connected. Despite of all the clues hinting this connection, no sound conclusion can be done as far as ocean circulation modelling is not able to correctly catch angular momentum of the oscillatory modes.

This book is a comprehensive study on how the national security sectors of China, India, Japan, Russia, and the United States have engaged the idea of climate change as an existential threat. Climate Change, National Security and Geopolitics examines the respective ways in which the five states have framed the issue of climate change in ...

Soil respiration (SR) is a main component of the carbon cycle in terrestrial ecosystems,
and being strongly affected by changes in the environment, it is a good indicator of the ecosystem’s
ability to cope with climate change. This research aims to find better empirical SR models using
25-year-long SR monitoring in two forest ecosystems formed on sandy Entic ...

This is a case note of two WTO panel reports in recent Palm Oil disputes. After providing an overview of the panel findings under Article 2.1 of the TBT Agreement, the note discusses what appears to be a modified legal standard for non-discrimination applied by the panel under this provision and the continued use of ...

A set of hydrometeorological models, has been used to assess the likely changes in Terek River runoff in the 21st century, taking into account climate and glaciation changes in the basin. It has been shown that runoff changes will range from –2 to +5% under the RCP 2.6 scenario and from –8 to +14% under ...

In early 2000-s the amplitude of the Chandler wobble (CW) started to decrease and in 2017-2020 reached its historic minima, comparable only with the minima of ~1928 yr. In 2021 the CW appeared again. We demonstrate that the phase of the CW is changing now, as during 1920-1930s. Since 2010 it has changed almost by ...

Earth rotation in recent epoch shows anomalies: its rotation velocity reached decadal maximum in 2024; the Chandler wobble (CW) of the rotation axis disappeared in 2018–2020, then resumed with a phase changed by 180^\circ
◦; the ampli-tude of the Free Core Nutation (FCO) decreased since 2021 as well. We analyzed the CW amplitude modulations since the ...

For the first time, a variability analysis of phenological dates of woody plant development in connection with climate change was conducted for the conditions of Primorsky Krai. The study is based on a continuous (from 1987 to 2022) series of phenological observations for five tree species from the Nature Chronicle of the Sikhote-Alin Reserve. According ...

Since the end of the Little Ice Age, glacier retreat has been recorded globally, with its rates steadily increasing. Glacier forelands serve as convenient areas for studying the patterns of biotic community formation during primary succession. Collembola (hereinafter – springtails) typically play key roles in primary successions, being among the first colonists of territories newly ...

This study analyzes agency and news values across verbal and visual modalities
in Croatian online news on the climate crisis, examining how climate change is
portrayed. We explore newsworthiness, visual framing, and metaphor, linking
agency to broader concerns about responsibility. In addition, the analysis traces
how different types of agency shape news values in both metaphorical and nonmetaphorical
micro-contexts. To ...

One of the major components of the Earth’s polar motion is Chandler wobble with 433-day period. To extract it from observations narrow-band filtering is required. We have developed method which joins Kalman filtering and band-pass filtering in direct time with the phase correction in reversed time. By using Euler-Liouville equation generating resonant CW as a ...

The energy supplies is a traditional problem for the EU due to the lack of its own resources. This issue has become most relevant after the deterioration of relations with Russia, formerly a leading energy partner. The Union began to explore options for diversification because it is not ready to implement a green transition at ...

Although climate change in the Arctic is recognised
as one of the most pressing issues in the region, its
dynamics, irreversibility, and the reasons for its occurrence and
intensification remain a subject of serious debate. The severity
of the impact of global warming on the Arctic ecosystem and
the potential risks of these threats spreading beyond the region
are yet to ...
