Timelaspse is a global zoomable video that lets you see how the Earth has changend over the past 30 years. It is made from 35 cloud-free annual mosaics, one for each year from 1984 to 2018, wich are made interactively explorable by Carnegie Mellon University CREATE Labs Time Machine Library, a technology for creating and viewing zooming and pannable timelapses over space and time.

The carbon 14 dating carried out on these woody elements dated them to 6000 years B.C. The plants were identified as oaks by a xylological study. To date, only two other examples of drowned forests are known in the world. In Mobile, off the coast of Alabama (United States), revealed by Hurricane Katrina (in 2005) and dated 50,000 years ago; and in Wales, exposed by a storm, in 2014. These exceptional discoveries are direct indicators of the position of the palaeo-littoral as it was before the rise in sea level, during the Holocene, the geological period of the last 10,000 years. They constitute a proven marking of the localization of the coastline of the time.

Over the past few decades there has been an increasing interest in building micro-dams across the whole of the Cordillera Negra, North-Central Andes, Peru. Given the difficulties in maintaining a regular flow of water, especially during the dry season, it is a logical response to a pressing need. Indigenous skill and landscape knowhow informed the selection of sites for damming. Modern engineers have followed their lead, such that present-day micro-dams often occupy the same space as the prehispanic ones. Aside from the obvious destruction of cultural heritage – usually without a proper archaeological survey – there is one other problem with this policy: not all the old dams which are now being reconstructed were built for retaining just water.

It’s used as measurements of gravity, i.e. gravimetry, to find out about the distribution of water on Earth. With the help of data from the satellite missions GRACE (2002 to 2017) and GRACE-Follow On (since mid-2018) we calculate maps of the Earth’s gravitational field every month. These maps not only depict continents and ocean basins with crusts of varying densities, but also the density and mass shifts in the Earth’s mantle as well as short-term changes in mass on and below the Earth’s surface.

The proposed NEED aims to construct two dams of a combined length of 637 km. The first between northern Scotland and western Norway (476 km) and the second between France and southwestern England (161 km). The project intends to separate the North and Baltic Seas from the Atlantic Ocean to protect Northern Europe against SLR. The project classifies the solutions to SLR into three categories namely, taking no action, protection, and managed retreat — and categorises NEED into the second category. NEED is expected to have the least direct impact on people’s daily lives and can be built at a reasonable cost. It can be implemented in other regions in the world including the Persian Gulf, the Mediterranean Sea, the Baltic Sea, the Irish Sea, and the Red Sea.

The Grand Ethiopian Renaissance Dam project, currently under construction in Ethiopia, is located approximately 40 km downstream of the confluence with the River Beles at a narrow point about 15 km upstream of the Ethiopian border with Sudan. The main dam is a roller compacted concrete (RCC) gravity dam with a maximum height of 175 m and a length of about 2 km at crest elevation, reaching a total volume of about 10 million m³.

Nicholas Bennett, a first year BA Design student at Goldsmiths, is the winner of the #CreateCOP25 competition launched by artist management agency Art Partner. The contest invited young creatives to submit artistic proposals that engage with contemporary issues around climate change.

Wallace “J.” Nichols is a scientist, wild water advocate, movement-maker, and author of the New York Times best seller book – Blue Mind: The Surprising Science That Shows How Being Near, In, On, or Under Water Can Make You Happier, Healthier, More Connected, and Better at What You Do. He takes a slow, collaborative approach with leaders in businesses, government, non-profits, and academia to inspire a deeper connection with nature and inventive solutions to pressing issues. His research and expeditions have taken him to coasts and waterways across North, Central and South America, to Asia, Africa, Australia, and Europe where he continually finds that the emotional connection to waters of all kinds–rather than force of financial gain–is what keeps his colleagues and collaborators working hard to understand and restore our blue planet.

To find out water, the researchers carried out a parallel crater study, similar to the one they had conducted for Mercury. In this case, they studied 12,000 craters on the moon using data from the LRO. They report that they found “a similar morphological trend” in craters on the south side of the Moon, near the pole. They suggest this indicates that such craters likely harbor thick ice deposits along with other materials similar to those that are believed to exist on Mercury. The researchers suggest that if this is indeed the case, then there could be up to 100 million metric tons of ice in such craters, which they note is double the amount of previous estimates based on data from the LCROSS impact study. The researchers conclude by suggesting that future Moon missions include the use of probes that can be used to study the shaded craters to confirm their suspicions.
