This location is not only associated with numerous majestic waterfalls, karst topography and multiple natural caves and speleothems with global scientific value, but is also of great significance to local people. These features have made this place an important area for geoscience research, as well as an important area for the development of geotourism. Cherrapunji is also the source of the ‘Meghalayan Age’, the most recent age in the geological timescale, defined by the International Commission on Stratigraphy (ICS) in 2018, for the past 4200 years of the Holocene. This article calls on researchers, government officials as well as the local people to take all the necessary steps to make Cherrapunji a UNESCO Global Geopark.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"40 6","pages":"243-247"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142724185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preparing for an uncertain future climate represents one of the biggest challenges humans have ever faced. Here, I take you back 62 million years ago (Ma) to a poorly studied short-lived global warming event known as the Latest Danian Event (LDE), which may represent a good analogue for current human-induced climate change. I discuss evidence for changes in temperature and pH of the oceans during the LDE, using novel geochemical proxies on the calcite shells of zooplankton to prove that the LDE was the first global ‘hyperthermal’ event of the Cenozoic. I also delve into the potential forcing mechanisms behind the event, outlining the critical outstanding questions which palaeoclimatologists are yet to answer. Most importantly, I highlight the lessons we can learn from the LDE about our future climate, allowing us to better plan, prepare and adapt.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"40 6","pages":"228-235"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gto.12495","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737406","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Information boards and leaflets are often used by scientists and environmental managers in these environments to communicate geoscience issues to the general public along hiking and trekking trails. Rock climbing sites are also prime locations where rock surfaces are exposed and where specific user groups interact with the physical landscape. Here, we describe the relationship between rock climbing and the nature of rock outcrops and the opportunity that this affords for more innovative ways of communicating geoscience information to a physically active and engaged public. As such, rock climbing sites can be considered geoheritage sites, where they represent sites of importance for people and communities (cultural heritage) as well as for their geological and educational value (geological heritage). The characteristics of rock climbing sites as geoheritage sites are discussed in this feature, as are the potential threats to the integrity of these sites.</p>","PeriodicalId":100581,"journal":{"name":"Geology Today","volume":"40 6","pages":"223-227"},"PeriodicalIF":0.0,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/gto.12494","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These are usually dark-coloured rocks rich in magnesium, poor in silica and lacking feldspars. Earth's mantle, which makes up 83 percent by volume and 67 percent by weight of the planet, consists largely of peridotite, which, although relatively sparse at the surface, therefore, is Earth's most abundant rock type. Unfortunately, the mantle, which lies on average at &gt;7 km under the oceans and &gt;35 km under the continents, is not directly accessible for observation and our information comes largely from seismic studies, inclusions in volcanic rocks and sections of the ocean floor which have been tectonically emplaced into the crust: the <i>ophiolite complexes</i> and <i>abyssal peridotites</i> of the oceans. Such rocks also occur when mafic minerals, such as olivine, pyroxene and spinel, accumulate in magma chambers.
