Global temperatures have increased 0.6°C over the past 100 years and are continuing to rise rapidly. Both human and animal species are threatened by climate change, as it is causing coastal changes, extreme weather events, droughts, and melting polar ice caps. Small actions like participating in Earth Hour, where hundreds of millions of people turn off lights for one hour, can help reduce carbon emissions and make a difference in addressing global warming.
The Earth’s climate is dynamic and characterised by trends, aberrations and quasi-periodic oscillations varying over a broad range of time-scales [1], which are governed by external (extraterrestrial systems) and/or internal(ocean, atmosphere and land system). Trends are largely controlled by plate tectonics, and thus to change gradually on million year time scale. Aberrations occur when the certain thresholds are passed and are manifested in the geological record as the unusual rapid (less than a few thousands of years) or extreme change in climate. The quasi-periodic oscillations are mostly astronomically paced; they are driven by astronomical perturbations that affect the earth’s orbit around the sun and the orientation of earth’s rotation axis with respect to its orbital plane. These perturbations are described by the three main astronomical cycles: eccentricity, precession and obliquity, which together determine the spatial and seasonal pattern of insolation received by the earth [2], eventually resulting in climatic oscillations of ten to hundreds of thousands of year [3].Sun being the main source of energy for the earth system controls the climate of it. Variation in solar activity and cosmic ray intensity has direct influence over climatic features such as cloudiness, temperature and rainfall [4]. Volcanic eruptions also force all elements of the climatic systems up to a varying degree but producing long term climatic signals in the ocean. The cumulative volcanic cooling effect at present offsets about one third of anthropogenic warming [5].Other than these causes paleoclimatologists also relates the past climate changes with movement of solar system[6], interplanetary dusts and influence of asteroids[7].However the recent variability in climate what earth is experiencing is unlikely due to any of the individual above factors rather it is due to the compound effect of complex interactions of all the natural as well as anthropogenic forcings.

John Holdren on Climate Change Challenge 2018 02-15Vincent Everts
In Nantucket I attended an amazing and scary presentation by John Holdren on Climate Change. John Paul Holdren was the senior advisor to President Barack Obama on science and technology issues through his roles as Assistant to the President for Science and Technology, Director of the White House Office of Science and Technology Policy, and Co-Chair of the President’s Council of Advisors on Science and Technology (PCAST).
Holdren was previously the Teresa and John Heinz Professor of Environmental Policy at the Kennedy School of Government at Harvard University, director of the Science, Technology, and Public Policy Program at the School's Belfer Center for Science and International Affairs, and Director of the Woods Hole Research Center.

Adverse effects of global warming and what can be done to reduce it?

Questions
a: What are some of the barriers to understanding an issue as complex as Climate Change?
b: Are you surprised by how people have ‘used’ the information about a hiatus?
c: Are arguments establishing global warming sufficient to promote action on climate change or
not?
d: Assuming you were to believe in anthropocentric climate change, using the arguments in this
subject, are you in favour of taxes or cap and trade for addressing climate change? Why or why
not? PLANETOZ BYGRAHAMREADFEARN Global warming has not stopped. People should
understand that the planet is a closed system. As we increase our emissions of greenhouse gases,
the fundamental thermal dynamics tells us we have added heat into the system. Once it\'s
trapped, it can go to a myriad of places-land surface, oceans, ice shelves, ice sheets, glaciers for
example HOSTED BY THE GUARDIAN England explained how the winds help the ocean to
absorb heat into the thermocline-that\'s roughly the area between 100 metres and 300 metres
deep. He says once the trade winds drop which is likely to come within years rather than decades
- then the averaged surface temperatures will rise sharply again. The \'pause\' in global warming
is not even a thing Media outlets across the world have extensively covered England\'s paper.
National Geographic told us the study revealed how the heat had been \"hiding\" in the oceans.
All signs point to an acceleration of human-caused climate change. So why all this talk of a
pause? Over at the ABC, we were told the paper gave an explanation for \"a pause in global
warming\" and that \"over the past 15 years the rate of global warming has slowed - and more
recently almost stalled.\" The IPCC in 2013 pointed out that more than 90% of the world?s extra
heat is being soaked up by the oceans, rather than lingering on the surface. Photograph:
Universal History Archive\'Getty Images On The Conversation, we had \"Global warming stalled
by strong winds driving heat into oceans The idea that global warming has \"paused\" or is
currently chillaxing in a comfy chair with the words \"hiatus\" written on it has been getting a
good run in the media of late. Even though these reports spoke in detail about the complexity of
the research (England feels the coverage generally has been very good), they could inadvertently
cement the idea that global warming has in some way stopped, when it hasn\'t. Much of this is
down to a new study analysing why one single measure of climate change- the temperatures on
the surface averaged out across the entire globe - might not have been rising quite so quickly as
some thought they might. But this is almost unavoidable. You can hardly blame journalists and
commentators for repeating the phrase that \"global warming is in a hiatus\" when the offending
word is in the itle of the scientific paper itself (Recent intensification of wind-driven circulation
in the Pacific and the ongoing warming hiatus But here\'s the thing. There never was a \"paus.
Similar to how global warming changed the world we live in (15)

In a May 9, 2024 paper, Juri Opitz from the University of Zurich, along with Shira Wein and Nathan Schneider form Georgetown University, discussed the importance of linguistic expertise in natural language processing (NLP) in an era dominated by large language models (LLMs).
The authors explained that while machine translation (MT) previously relied heavily on linguists, the landscape has shifted. “Linguistics is no longer front and center in the way we build NLP systems,” they said. With the emergence of LLMs, which can generate fluent text without the need for specialized modules to handle grammar or semantic coherence, the need for linguistic expertise in NLP is being questioned.

winters really had gotten milder, and

right… weather men have no doubt that
the world at least for the time being is
