What Causes Sea Level Rise?
People have been measuring local sea level at certain locations along the coasts for hundreds of years. And NASA has been measuring the global sea level for almost three decades. Over this time, scientists have observed that the global sea level has been rising. The ocean is about 7 to 8 inches higher now than it was a century ago.
Why? Because Earth is getting warmer.
Comprehension Questions:
1. What causes the level of the water to rise and sink all day long?
2. The average height of the ocean in a particular place is called the _______ _________ ________.
3. NASA measures the average sea level of the whole ocean from space. What is another name for the average sea level of the whole ocean?
4. True or False: As Earth warms, the ocean warms, too.
5. What is the name of the NASA satell...

What Happens If Sea Level Drops by 1 Kilometre? #shorts
A sea level drop of 1 kilometer reveals underwater geological formations. This drastically
changes the world map.
Australia extends north, merging with Indonesia. Tasmania connects to mainland Australia,
gaining 10 to 20% more land.
New Zealand’s islands merge into one, extending eastward.
Southeast Asia connects by land, with Sumatra and Java fusing together. India and Sri Lanka
join with a massive land bridge.
Europe becomes a single landmass. The UK joins Ireland and a new land bridge forms
between North America and Europe.

This is what sea level rise will do to coastal cities
Sea level rise is already redrawing coastlines around the world. What happens when the coast retreats through a major city? We look at how the world map will change in the year 2100, and what coastal cities can do to defend themselves.
Correction: An early version of this video suggested that researchers expect to see four feet of sea level rise by the end of the century. While researchers do expect to see at least that level of sea level rise in the future, the exact timing is difficult to project. We regret the error.

Nothing To Sea Here Folks
In this "Fact Check" video from the Climate Discussion Nexus, Dr. John Robson expands on our Sea Level Check series to rebut claims of dangerous, accelerating, man-made sea level rise by examining the actual history and current state of melting land ice, changes in the land and other complex factors that contribute to this non-crisis.

15 Places We Will Lose to Rising Sea Levels
About 71% of the planet is covered in water. No matter which way you cut it, though, that number seems to be growing at a pretty alarming rate. The ocean is getting bigger and sea levels are rising around the world and it seems like no one is immune to it. Cities can build up to avoid it, but the massive buildings only bog us down further. Beach communities are built for beautiful ocean views only to fall back into the sea. It can be scary, but there are always solutions. So join us for today’s video, as we countdown 15 places we will lose to rising sea levels.

Why is Sea Level Rising? We Asked a NASA Scientist
Why is sea level rising?
Global sea levels are rising as a result of human-caused global warming, with recent rates being unprecedented over the past 2,500-plus years. NASA JPL’s sea level rise expert Ben Hamlington explains how our warming planet is causing sea levels to rise.

GlossBERT: BERT for Word Sense Disambiguation with Gloss Knowledge (Research Paper Walkthrough)
#bert #wsd #wordnet
This research uses BERT for Word Sense Disambiguation use case in NLP by modeling the entire problem as sentence classification task using the Gloss knowledge. They show state-of-art results on benchmark datasets.
⏩ Abstract: Word Sense Disambiguation (WSD) aims to find the exact sense of an ambiguous word in a particular context. Traditional supervised methods rarely take into consideration the lexical resources like WordNet, which are widely utilized in knowledge-based methods. Recent studies have shown the effectiveness of incorporating gloss (sense definition) into neural networks for WSD. However, compared with traditional word expert supervised methods, they have not achieved much improvement. In this paper, we focus on how to better leverage gloss knowledge in a...

Disambiguating Explicit and Implicit Geographic References in Natural Language: When people speak, both they and their utterances are situated in place and time. Our utterances reflect where we are from, where we are right now, and where we are talking about—among many other things, including personality, social status, and the topics under discussion. As hearers, we naturally incorporate locational awareness into our understanding of what we are told. That is to say, we geographically ground the meaning of natural language utterances.

Ocean
Body of salt water covering the majority of Earth
This article is about natural science aspects of Earth's oceans as well as threats from human activities. For more on human experience, history and culture of oceans, see Sea. For other uses, see Ocean (disambiguation).
The ocean (also known as the sea or the world ocean) is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. Distinct names are used to identify five different areas of the ocean: Pacific (the largest), Atlantic, Indian, Southern, and Arctic (the smallest). Seaw...

#bert #wsd #wordnet
This research uses BERT for Word Sense Disambiguation use case in NLP by modeling the entire problem as sentence classification task using the Gloss knowledge. They show state-of-art results on benchmark datasets.
⏩ Abstract: Word Sense Disambiguation (WSD) aims to find the exact sense of an ambiguous word in a particular context. Traditional supervised methods rarely take into consideration the lexical resources like WordNet, which are widely utilized in knowledge-based methods. Recent studies have shown the effectiveness of incorporating gloss (sense definition) into neural networks for WSD. However, compared with traditional word expert supervised methods, they have not achieved much improvement. In this paper, we focus on how to better leverage gloss knowledge in a supervised neural WSD system. We construct context-gloss pairs and propose three BERT-based models for WSD. We fine-tune the pre-trained BERT model on SemCor3.0 training corpus and the experimental results on several English all-words WSD benchmark datasets show that our approach outperforms the state-of-the-art systems.

Disambiguating Explicit and Implicit Geographic References in Natural Language: When people speak, both they and their utterances are situated in place and time. Our utterances reflect where we are from, where we are right now, and where we are talking about—among many other things, including personality, social status, and the topics under discussion. As hearers, we naturally incorporate locational awareness into our understanding of what we are told. That is to say, we geographically ground the meaning of natural language utterances. In this talk, I will discuss both toponym resolution (e.g., identifying which Springfield is intended in a passage) and general text geolocation—deriving geographical gists from free-running text that perhaps has no explicit mentions of places. I’ll cover supervised and semi-supervised methods for solving these tasks. I’ll also briefly discuss how this work might generalize the now commonplace treatment of words-as-vectors into computational models of word meaning that use multi-dimensional representations over words, geography, time, and images.

Ocean
Body of salt water covering the majority of Earth
This article is about natural science aspects of Earth's oceans as well as threats from human activities. For more on human experience, history and culture of oceans, see Sea. For other uses, see Ocean (disambiguation).
The ocean (also known as the sea or the world ocean) is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. Distinct names are used to identify five different areas of the ocean: Pacific (the largest), Atlantic, Indian, Southern, and Arctic (the smallest). Seawater covers approximately 361,000,000 km2 (139,000,000 sq mi) of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.
Oceanographers split the ocean into vertical and horizontal zones based on physical and biological conditions. The pelagic zone is the open ocean's water column from the surface to the ocean floor. The water column is further divided into zones based on depth and the amount of light present. The photic zone starts at the surface and is defined to be "the depth at which light intensity is only 1% of the surface value": 36 (approximately 200 m in the open ocean). This is the zone where photosynthesis can occur. In this process plants and microscopic algae (free floating phytoplankton) use light, water, carbon dioxide, and nutrients to produce organic matter. As a result, the photic zone is the most biodiverse and the source of the food supply which sustains most of the ocean ecosystem. Ocean photosynthesis also produces half of the oxygen in the earth's atmosphere. Light can only penetrate a few hundred more meters; the rest of the deeper ocean is cold and dark (these zones are called mesopelagic and aphotic zones). The continental shelf is where the ocean meets dry land. It is more shallow, with a depth of a few hundred meters or less. Human activity often has negative impacts on the ecosystems within the continental shelf.
Ocean temperatures depend on the amount of solar radiation reaching the ocean surface. In the tropics, surface temperatures can rise to over 30 °C (86 °F). Near the poles where sea ice forms, the temperature in equilibrium is about −2 °C (28 °F). In all parts of the ocean, deep ocean temperatures range between −2 °C (28 °F) and 5 °C (41 °F). Constant circulation of water in the ocean creates ocean currents. These directed movements of seawater are caused by forces operating on the water, such as temperature variations, atmospheric circulation (wind), the Coriolis effect and salinity changes. Tides create tidal currents, while wind and waves cause surface currents. The Gulf Stream, Kuroshio Current, Agulhas Current and Antarctic Circumpolar Current are all major ocean currents. Currents transport massive amounts of water and heat around the world. By transporting these pollutants from the surface into the deep ocean, this circulation impacts global climate and the uptake and redistribution of pollutants such as carbon dioxide.
Ocean water contains a high concentration of dissolved gases, including oxygen, carbon dioxide and nitrogen. This gas exchange occurs at the ocean's surface and solubility depends on the temperature and salinity of the water. Carbon dioxide concentration in the atmosphere rises due to fossil fuel combustion, which causes higher levels in ocean water, resulting in ocean acidification. The ocean provides crucial environmental services to humankind, such as climate regulation. It also provides a means of trade and transport as well as access to food and other resources. It is known to be the habitat of over 230,000 species, but may hold considerably more – perhaps over two million species. However, the ocean faces numerous human-caused environmental threats, such as marine pollution, overfishing, and effects of climate change on oceans such as ocean warming, ocean acidification and sea level rise. The continental shelf and coastal waters that are most affected by human activity are particularly vulnerable.
