Hurricane Katrina

Hurricane Katrina
Many people acted heroically in the aftermath of Hurricane Katrina. The Coast Guard, for instance, rescued some 34,000 people in New Orleans alone, and many ordinary citizens commandeered boats, offered food and shelter, and did whatever else they could to help their neighbors. Yet the government–particularly the federal government–seemed unprepared for the disaster. (For one thing, many had nowhere to go. Katrina pummeled huge parts of Louisiana, Mississippi and Alabama, but the desperation was most concentrated in New Orleans. In all, Hurricane Katrina killed nearly 2,000 people and affected some 90,000 square miles of the United States. Related:  Course 7

City Birds Outsmart Country Birds City dwellers can attest that the animals they share the city with—the pigeons, rats, roaches—can all be pretty brazen when they're prowling for a bite. This is Scientific American’s 60-Second Science, I’m Christopher Intagliata. Got a minute? While visiting Barbados, McGill University neurobiologist Jean-Nicolas Audet noticed that local bullfinches were accomplished thieves as well. [Jean-Nicolas Audet:] “They were always trying to steal our food. And that gave him an idea. [Audet:] Since this bird species [is] able to solve amazing problems in cities, and they're also present in rural areas, we were wondering... ...Are the rural birds also good problem solvers, and they just don't take advantage of their abilities? So Audet and his McGill colleagues captured Barbados bullfinches, both in the island's towns and out in the countryside. And it turns out the city birds really could solve puzzles faster. Thanks for the minute. —Christopher Intagliata Credits

»Sluta skräm eleverna« Let´s leave. fine art print 2013.©Erik Johansson Vägen mellan Uppsala och Gävle är inte världens roligaste ens när trafiken flyter. Asfaltkokare, bilköer och pissigt juliväder gjorde nu inte saken bättre, så jag satte på radion och hamnade mitt i en sändning från Sveriges Radio, i programserien Kossornas planet. Det var inget barnprogram, ändå var språket på förskolenivå. Jag stängde av igen. Immenent. fine Art Print 2016. Endast komplett misslyckade pedagoger tror att något blir bättre av att man prackar på barn en massa dramatiserade halvsanningar som syftar till att framkalla svårhanterliga skuldkänslor och halvreligiösa idiotföreställningar om att människan är ond och naturen god. Förr berättade man inte för barn om Helvetet före konfirmationen; det var en av de få bra sakerna med dåtidens patriarkala religionsförtryck. Själv har jag helt slutat panta flaskor och burkar. Men barnen är ju så miljöintresserade! Reverberate. fine art print 2011. ”Vår planet mår inte bra.

Top dog: Scientists teach border collie to understand sentences and 1,000 words Chaser the dog now able to understand nouns and verbs, researchers sayIn first three years she learned and remembered 1,022 proper nounsThe objects included 800 cloth animals, 116 balls, and 100 plastic toysResearch carried out by Wofford College, in North Carolina By Luke Salkeld for the Daily Mail Published: 16:23 GMT, 22 December 2013 | Updated: 09:53 GMT, 23 December 2013 Researchers believe they have taught a border collie to respond to words in the same way that a human child does Border collies are known for their high level of intelligence. But Chaser has proved herself as the undoubted top dog after learning to understand 1,000 words - plus a smattering of English grammar. Researchers believe the nine-year-old has learned to respond to words in the same way that a human child does. They say Chaser was able to demonstrate understanding of nouns and verbs. In the first three years, she learned and remembered 1,022 proper nouns. She could also respond to novel objects.

Ändrat klimat kan driva miljoner på flykt GARHWAL. Det skedde under fyra junidagar 2013. Medan Sverige pratade om prinsessan Madeleines smekmånad och Edward Snowdens läckor om massövervakning gillrade klimatet en dödsfälla i Himalayabergen. Det som tidigare var bördig jordbruksmark liknar i dag gotländska stenstränder, fast här kantade av sönderslitna hus. Armeringsjärn spretar ur cementblocken som avklippta elkablar. – Det var ingen översvämning, det var en tsunami, säger 49-årige Kelash Bhatt, som bor i närheten. Vädersystemen utlöste ett tvåfrontskrig. Den turkosa forsen dånar förbi nära byn Agastmuni. Bland rasmassorna en bit bort sitter byggarbetaren Sarendra Saha. – Vi gör så att man kan klättra upp till fler hus. Vi utmanar naturen och då tar den revansch på oss. Byborna beskriver de fyra junidagarna 2013 som guds verk. – Vi utmanar naturen och då tar den revansch på oss, säger bybon Sumati Devi, vars två söner dog i skyfallen. Himalayabergen är bara en av klimathotets frontlinjer i Indien. Alla förlorade sina söner.

Mikä ilmastonmuutos? | Open ilmasto-opas Ilmastonmuutos on vakavin ihmiskuntaa koskaan kohdannut ympäristöongelma. Se vaikuttaa ihmistoimintaan ja luonnonympäristöihin jo nyt ja vaikutukset tulevat lisääntymään tulevaisuudessa. Ihmisten toiminnan vaikutus ilmastonmuutoksen etenemisessä on ratkaiseva ja katastrofaalinen ilmastonmuutos voidaan edelleen estää, jos niin halutaan. Ilmastonmuutos on osa moninaista ympäristö- ja kestävyysongelmien vyyhtiä ja toisaalta sen ratkaisut edustavat kestävän kehityksen mukaista elämäntapaa. The Value Web Ilmastonmuutoksen syyt ja seuraukset Louis Vest Ilmastonmuutos on kasvihuoneilmiön voimistumista. Ihmiskunta kuitenkin tuottaa valtavia määriä kasvihuonekaasuja, jotka voimistavat luonnollista kasvihuoneilmiötä. Ilmasto on muuttunut aina, mutta nykyinen, teollisen vallankumouksen puitteissa aiheutunut muutos on poikkeuksellisen nopea. IImastonmuutoksen seurauksena sademäärät, lämpötilat ja ilmakehän kaasukoostumus muuttuvat maapallolla. Ilmastonmuutoksen hillintä ja siihen sopeutuminen .Martin.

Eight months on, is the world's most drastic plastic bag ban working? Waterways are clearer, the food chain is less contaminated with plastic – and there are fewer “flying toilets”. A year after Kenya announced the world’s toughest ban on plastic bags, and eight months after it was introduced, the authorities are claiming victory – so much so that other east African nations Uganda, Tanzania, Burundi and South Sudan are considering following suit. But it is equally clear that there have been significant knock-on effects on businesses, consumers and even jobs as a result of removing a once-ubiquitous feature of Kenyan life. “Our streets are generally cleaner which has brought with it a general ‘feel-good’ factor,” said David Ong’are, the enforcement director of the National Environment Management Authority. “You no longer see carrier bags flying around when its windy. Ong’are said abattoirs used to find plastic in the guts of roughly three out of every 10 animals taken to slaughter. In the Mathare community, this is good news. There has been push-back.
