Climate change is making waves stronger and putting coastlines at risk

As the upper ocean has warmed, wind patterns have been affected globally, resulting in stronger ocean waves. The researchers behind the Nature Communications study say they found a long-term trend of wave power increasing globally in direct association with historical warming of the ocean surface.The researchers say their results show that global wave power could be used as an indicator of global warming similar to how atmospheric carbon dioxide concentration levels, global sea level rise, or global surface atmospheric temperatures are used now. Global climate change is impacting Earth’s oceans in a number of ways, from higher water temperatures and rising sea levels to acidification and oxygen depletion.Now, scientists have reported another change to oceans  wrought by global warming: According to research published in the journal Nature Communications this month, the energy of ocean waves has grown over the past seven decades, which could have significant implications for coastal communities and ecosystems.The energy in ocean waves is transmitted from the wind. As the upper ocean has warmed, wind patterns have been affected globally, resulting in stronger ocean waves. The researchers behind the Nature Communications study say they found a long-term trend of wave power increasing globally in direct association with historical warming of the ocean surface.“For the first time, we have identified a global signal of the effect of global warming in wave climate,” Borja G. Reguero, a researcher in the Institute of Marine Sciences at the University of California, Santa Cruz in the United States and the study’s lead author, said in a statement. “In fact, wave power has increased globally by 0.4 percent per year since 1948, and this increase is correlated with the increasing sea-surface temperatures, both globally and by ocean regions.”Previous analyses of the global wave climate, or how wave characteristics change over time, have tended to focus on historical trends in mean and extreme values for parameters such as wave height, Reguero and co-authors note. Wave heights have increased in recent decades, especially at higher latitudes in both hemispheres.“Satellite-based altimeter measurements from 1985 to 2008 reveal increases of 0.25% per year for the 90th wave height percentile and 0.50% per year for the 99th percentile, in both hemispheres,” the researchers write in the study. “[D]ata also show significant increases in extreme wave heights at the high latitudes of the southern hemisphere, 0.25–0.9% per year for the 90th percentile in the north Atlantic and the north Pacific, and decreases in the mid-latitudes.” In addition to changes in wave heights, wave periods have also increased, and the direction of waves has shifted in some cases, such as in the southern ocean and in the north Atlantic.Changes in global wave energy have received less attention, the researchers say, “particularly in the context of climate change.” They add that wave power has not been studied as a climate change indicator yet, but they found that “it can potentially characterize the long-term behavior of the global wave conditions better than wave heights.”Study co-author Inigo J. Losada, director of research at the Environmental Hydraulics Institute at Spain’s University of Cantabria, said that the study results show that global wave power could be used as an indicator of global warming similar to how atmospheric carbon dioxide concentration levels, global sea level rise, or global surface atmospheric temperatures are used now.Understanding how global wave power responds to oceanic warming also has important implications for adapting coastlines to the impacts of climate change on infrastructure, coastal cities, and small islands. Wave power is a “key driver of coastal change and flooding,” the authors of the study write, and as wave energy increases, the effects will become more profound.For instance, as sea levels rise, more wave energy will reach shore, exacerbating impacts to shorelines. But regional differences in upper-ocean warming will mean that wave power changes are different in each ocean basin. This variability in wave energy across regions and at different times of the year are most apparent in the heightened flooding and erosion risks to Pacific coastlines during El Niño events, “which are explained by our [wave power] patterns,” according to the authors. “Regionally, changes in the extratropical generation areas of the Southern Ocean and North Pacific, where the [wave power] is more severe, should receive special attention.“Our results indicate that risk analysis neglecting the changes in wave power and having sea level rise as the only driver may underestimate the consequences of climate change and result in insufficient or maladaptation,” co-author Fernando J. Méndez, associate professor at Universidad de Cantabria, said in a statement.CITATION• Borja G. Reguero, Iñigo J. Losada, & Fernando J. Méndez. (2019).

It is mentioned that planting trees in village common lands will have negative affects socially and ecologically. There is no need to even have to agree or disagree with it, because, you also mentioned the fact that Cauvery Calling aims to plant trees only in the private lands of the farmers. So, plantation in the common lands doesn’t come into the picture.2.I don’t see that the ecologists are totally against this project, but just they they have some concerns, mainly in terms of what species of trees will be planted. And because there was no direct communication between the ecologists and Isha Foundation, it was not possible for them to address the concerns. As you seem to have spoken with an Isha spokesperson, if you could connect the concerned parties, it would be great, because I see that the ecologists are genuinely interested in making sure things are done the right way.May we all come together and make things happen.Rare Amazon bush dogs caught on camera in BoliviaCarrot1 Feba very good iniciative to be fallowed by the ranchers all overSponsoredlast_img read more

Semantic Web Wish List 2009

first_imgA Web Developer’s New Best Friend is the AI Wai… At the end of last year we presented our list of the top 10 Semantic Web Apps of 2008. ReadWriteWeb reader Zoltán Andrejkovics wrote in to us afterwards, suggesting that we do a post looking at what Semantic Web apps we’d like to see emerge in 2009. Zoltán gave us 5 apps he wants to see this year, and we also asked our Twitter friends for their views (you can follow ReadWriteWeb on Twitter here). We at ReadWriteWeb are tracking the Semantic Web space closely – so far we’ve identified 20 products (see our first 10, then 10 more) that we’re paying particular close attention to. But we know there is a lot of opportunity yet for commercializing the Semantic Web, so we encourage you to add your wish list in the comments.At ReadWriteWeb, we look for more commercial Web apps – whether they be consumer or enterprise. So here are 5 of those we’d like to see emerge and/or grow during 2009:Microsoft makes a very bold play with Powerset technology and starts to challenge Google in search (despite Google’s attempts to use semantic web technology, we’d love Microsoft to ramp it up in search – competition is good for consumers!).Semantic Web advertising apps for publishers – we have our eye on Dapper MashupAds in this sector, but we’d like to see others take up this challenge too.Semantic apps for managing your finances – makes connections between transactions, things that you wouldn’t normally pick up.Semantic apps for health industry – there are many opportunities here, but in general there is much the Semantic Web could do to organize the maze of data in the health indsutry.A Personalized Memetracker – Techmeme founder Gabe Rivera would be astonished if this happens, but we’d love to see a product that can give a Techmeme-like organization and layout to one’s RSS feeds. So at a glance, you can see which stories in your own set of RSS feeds are hot and who’s linking to them. Whether Semantic Web technology can achieve that, we don’t know 😉Zoltán Andrejkovics, who suggested this topic, is a PhD student at Corvinus University of Budapest and his 5 wishes as a researcher are:Smart notes; easy to find/browse notes, using NLP search. Smart RSS; automatic article-collecting app based on my own interests. Mind writing; using not only words, but “thought” objects, that the NLP engine puts into words.Assistant; “my mirror”, learns from my words, behavior on the net, and supports my work, handles calendar, etc. Smart bookmarks; works like smart notes. Here are some reactions from RWW readers on Twitter (it was very short notice before this post was published, so if we missed you please add your wish list to the comments):superphoebe: “I’d love to see more semantic blogging tools like Zemanta, but with more sources, really great search and a super simple dashboard.”Marcelo Sánchez: “Zigtag for bringing real semantic tagging and Freebase as the next Wikipedia”garlin: “I’d like an app that uses semantic tech to identify/analyze the political bias in a particular article/piece of writing.”kevin grandia: “would love to see a better way of submitting content to conversion services like Calais.”Rama Mamuaya: “language based search engines like Hakia or Powerset should be rising fast. Should evolve from search engine, to answer engine.” Jean-Jacques Halans: “mobile safari reading microformats, for adding to calendar, contacts, lookup address on map”Stephen Edgar: “More on the Semantic Wiki app’s and API’s such as“Chris Saad: “my hope is to see APML import AND export from more apps ;)”Tell us your Semantic Web App Wish List for 2009.

Do VCs Like Games? Gaming Startups and Investors

first_imgRelated Posts Tags:#start#startups audrey watters 8 Best WordPress Hosting Solutions on the Market A Web Developer’s New Best Friend is the AI Wai…center_img Why Tech Companies Need Simpler Terms of Servic… The gaming industry continues to see phenomenal growth – from console systems to social games. The 12 million subscribers of Blizzard’s World of Warcraft – once the giant of gaming – now seems small compared to the 80 million Farmville players. Farmville’s maker, Zynga was recently estimated to be worth $5 billion – a valuation that appears to bode well for investors and for startups. But are games good buys? Can gaming startups attract the investment they need?Gaming industry consultant Nicholas Lovell recently wrote a post on the blog Gamasutra where he suggested “Four Reasons Why VCs Won’t Fund Game Companies.” Lovell’s arguments are as follows1. VCs don’t invest in projectsLovell contends that game developers are good at creating (and even at pitching) projects, but that VCs don’t necessarily care what makes a good project – in other words, what makes a good game. “Investors care about businesses; developers show them projects.”2. Investors want to see a running business, not an idea3. VCs want sustainable businessesLowell writes, “Traditional games developers are really difficult for any investor to fund. They look like quite late-stage businesses: they may have hundreds of staff, millions in turnover and a proven track record. But fundamentally, they are always just one deal away from bankruptcy. They look like startups from a risk perspective but are like late stage investments from a reward perspective.”4. History sucksThe history of the gaming industry is full of failed businesses, and as such VCs find the investment there to be risky.Arguably, investors’ opinions might be changing, particularly given the rapidly increasing popularity of social games. While traditional console games and MMORPGs require significant investment and substantial development time before a game is “live,” social games are, arguably, “lighter.” With the growth in virtual goods and virtual currency, even “free” social games, as Farmville and the like have demonstrated, can become vastly popular and very profitable.

In four matches that he played, the Baroda left-arm medium pacer went wicketless and his economy touched 7.62.Irfan has not played for India since August 2012 and not considered express pacer or a big hitter in Indian cricket fraternity.He even failed to show off his skills with the bat last seaon. In three innings, the left-handed batsman hit just 11 runs.Both Ishant and Irfan were once India’s most sought after players but the saying ‘perform or perish’ fits best in this case.last_img read more
