Climate change is exposing millions of workers to excessive heat, risking their health and income and threatening to erase more than $2.0 trillion in annual productivity by 2030, a UN report warned Thursday.More than one billion workers in countries hard-hit by global warming are already grappling with increasing severe heat, according to the report: "Climate Change and Labour: Impacts of Heat in the Workplace.""Already in the current situation, several percent of working hours can be lost in highly exposed regions," said the report, a collaboration between several UN agencies and international unions.The global productivity loss is expected to top $2.0 trillion annually by 2030, as sweltering temperatures force outdoor workers and manual labourers to slow down, take longer breaks or even move to find work in a cooler climate."When workers are put under these hot-house conditions, their capacity to work is dramatically impacted," Philip Jennings, head of UNI Global Union, told AFP.Working in temperatures over 35 degrees Celsius (95 degrees Fahrenheit) is considered health hazardous.Some labourers exposed to such conditions have no choice but to continue working, sometimes without access to drinking water or shade to cool off in. "Those who work in the fields may ruin their health just by trying to put a meal on the table," Saleemul Huq, head of the International Centre for Climate Change and Development, warned in a statement.An estimated four billion people live in the areas most exposed to climate change.Those regions include much of southern Asia, the southern United States, Central America and the Caribbean, northern South America and north and west Africa.In West Africa, the number of very hot days each year has already doubled since the 1960s, with an increase of around 10 additional hot days each decade, the report said.And in Kolkata, India, each decade brings an additional 12 days where the mercury soars above 29 C, it said.India has already lost around three percent of available daylight working hours annually due to extreme heat, and without dramatic action to rein in global warming could be looking at eight percent respectively by 2085, the report showed.The report comes after 160 nations last week signed a historic agreement reached in Paris aimed at keeping a rise in global temperatures below 1.5 degrees Celsius.But experts warn that capping the global temperature rise at that level will be difficult, with many expecting at least a 2 C rise. And if the world does not act to rein in greenhouse gas emissions, scientists say the world is heading for a 4 C warmer world.Thursday's report warned that even if global leaders manage to limit warming to 1.5 C, some of the hardest-hit areas will see an entire month of added extreme heat in 2030 compared to 2010.

This year, Google is celebrating Earth Day, April 22, with five different Google Doodles illustrating some of the planet's major biomes: tundra, forest, grasslands, desert, and coral reefs. They're neat and definitely worth checking out. Personally, I like spending Earth Day looking through some of the best new discoveries we've made about this breathing, seething, blue-green planet of ours â€” the only place in the universe where life is known to exist. After all, a lot has changed since the very first Earth Day in 1970. Back then, America's most urgent environmental problems were air and water pollution. In the years since, we've made major progress mopping that up, only to confront fresh challenges like global warming and ocean acidification. Even today, our knowledge of the Earth keeps evolving with each passing year. We've uncovered brand-new geological features. We've brought endangered species back from the brink of extinction. We've transformed the atmosphere, for better and worse. So here's a list of some of the most surprising, hopeful, and worrisome things we've learned about Earth since the last Earth Day: 1) Scientists found an entirely new, 600-mile-long coral reef at the mouth of the Amazon (Wikimedia/NASA) Satellite image of mouths of Amazon River in Brazil, with Marajó Island in the center, and the cities (in red) of Macapá (left) and Belém (right). You'd think that, by now, we'd have mapped every last nook and cranny on this planet. Not so! We're still discovering new surprises all the time. This week, a team of Brazilian and American scientists told the Atlantic they'd discovered an entirely new coral reef spanning 3,600 square miles of ocean floor at the mouth of the Amazon River. Robinson Meyer recounts the backstory. Ever since the 1970s, people had suspected there might be a coral reef lurking on the ocean floor there, beneath the turbid waters. But no one knew for sure. Then, recently, a team of researchers journeyed to the region to study carbon dioxide absorption by the Amazon's freshwater plume. One of the scientists, Rodrigo Moura, brought along a dredge to check to see what was down beneath the surface. And jackpot: He pulled up coral, sponges, stars, and fish. Mind you, not all the coral reef news this year has been quite so wondrous. In Australia, scientists recently announced that 93 percent of the Great Barrier Reef has succumbed to coral bleaching, a destructive phenomenon that occurs when ocean temperatures rise sharply. The coral expel their symbiotic algae, turning a ghastly white and becoming more vulnerable to disease. It's a real problem as global warming keeps boosting temperatures. Coral reefs are often thought of as the rain forests of the ocean, home to 25 percent of marine species. So conservationists are racing desperately to save them before they vanish altogether. In the New Yorker, Elizabeth Kolbert recently wrote about scientists trying to breed hardier coral that can survive this new era of frequent bleaching. 2) We've discovered dozens of additional species â€” as well as a few thought to be extinct (Lieven Devreese) Photograph of the Bouvierâ€™s red colobus (Piliocolobus bouvieri), long thought to be extinct. At this point, scientists have described about 1.5 million different species on the Earth. That sounds like a lot, but estimates suggest there are another 4 million species still waiting to be discovered. Researchers managed to chip away at that number over the past year. New discoveries include a cartwheeling spider in Morocco, a giant walking stick insect 9 inches long in Vietnam, and a new species of pufferfish off the coast of Japan that create intricate geometric spawning nests in the sand on the ocean floor. You can see more photos of some recent discoveries here. But one of the neatest discoveries last year wasn't even a new species. The Bouvier's red colobus monkey, which lives in the Republic of Congo, was thought to have gone extinct back in the 1970s â€” a victim of heavy logging and hunting. Then, in 2015, primatologists Lieven Devreese and Gaël Elie Gnondo Gobolo stumbled upon a mother and infant Bouvier's red colobus monkey while exploring the swamp forests along the Bokiba River and took a photo. It was the first confirmed sighting in decades of a species once believed gone forever. 3) Earth has 3 trillion trees â€” far more than we thought (David McNew/Getty Images) Just a few of our 3.04 trillion trees. In September 2015, in a groundbreaking study in Nature, a team of scientists combined both satellite imagery and ground-based surveys to estimate that the planet has 3.04 trillion trees â€” way, way, way more than the previous estimate of 400 billion. The researchers estimated that forest cover was most pervasive in the tropics and subtropics, which have some 1.39 trillion trees. Temperate forests have 610 billion trees and boreal forests in the far north have another 740 billion. Russia has by far the most trees â€” some 641 billion, much of them in Siberia. The United States has another 228 billion trees. Oh, except here's the not-so-good news: The researchers also estimated that Earth now has 46 percent fewer trees than existed before humans first started cutting them down thousands and thousands of years ago. What's more, they estimated that deforestation has accelerated in recent years: Logging, agriculture, wildfires, and pests contribute to the loss of about 15.3 billion trees each year, while about 5 billion end up growing back. (On the flip side, there have been a few notable forest conservationsuccesses lately, so the story isn't entirely bleak.) 4) We unearthed homo naledi, a new species of ancient human that once roamed the Earth This one was a major revelation: In September 2015, an international team of researchers announced that they'd discovered fossils of a new species of ancient human that, they believe, lived some 2 to 3 million years ago. It's name? Homo naledi. The story actually started years ago, when researchers discovered mysterious bone fragments â€” hundreds of them â€” in a cave in South Africa. Eventually, they realized this was a brand-new hominin, similar to Homo erectus, albeit with smaller brains. There's also some evidence that H. naledi may have buried its dead. My colleague Joseph Stromberg wrote about the discovery here: "When it comes to the study of human evolution, all this is a really big deal. To date, we know of only a handful of other species similar enough to us to fit in to our genus: Homo. Scientists will debate this designation for H. naledi â€” as they do for all newly discovered species â€” but the bottom line is that these fossils, detailed in a pair of newpapers in the journal eLIFE, give us a fascinating glimpse into a new part of our ancient history." 5) We learned unicorns and humans once coexisted. (Alas, really ugly unicorns.) Painting of the Elasmotherium sibiricum or "Siberian unicorn" by Heinrich Harder. The Elasmotherium sibiricumis a creature often described as the "Siberian unicorn." For a long time, scientists thought it went extinct some 350,000 years ago â€” well before humans ever came to the Siberian plains. Until recently, that is. In March 2016, a study in the American Journal of Applied Science described a skull discovered in Kazakhstan that suggests that a subpopulation of, uh, "unicorns" still roamed the Earth just 29,000 years ago. They may have even co-existed with humans. Scientists are now trying to figure out just how the animals in this particular region survived for so much longer than the rest of their brethren. That said, "unicorn" seems like a bit of a misnomer. Here's how Ellen Brait describes it in the Guardian: "It was about 6 feet tall, 15 feet long, and weighed about 9,000 pounds, making it more comparable to a woolly mammoth than a horse." 6) West Antarctica's ice sheet could melt faster than anyone realized Icebergs, Paradise Harbour, Antarctic Peninsula, Antarctica. Not all of the discoveries about our planet over the last year have been inspiring. Some have been downright unnerving. In March 2016, climate scientists took a fresh look at the West Antarctic Ice Sheet, which has been melting in dribs and drabs for decades as humans have been burning fossil fuels and increasing global warming. If this ice sheet were to slide entirely into the ocean, it would raise sea levels worldwide by 12 feet on average. Most experts had, however, long assumed this wouldn't happen for hundreds or maybe even thousands of years. Now this new study, published in Nature, has thrown that complacency into question. The researchers used sophisticated computer models to look at a variety of plausible processes by which the ice sheet could disintegrate as temperatures keep rising â€” including some that had not been incorporated into previous models, such as "hydrofractures" and "cliff collapses." This new model was much better able to explain the Antarctic ice sheet's behavior in Earth's distant past, during periods when it has also been much warmer. But here's where things got hairy: This model also spit out worrisome results for the future. The researchers found that the West Antarctic Ice Sheet could start destabilizing rapidly within decades, not centuries, if greenhouse gas emissions kept soaring. When added to projections for melting ice elsewhere, that could push global sea levels up 5 to 6 feet by 2100 â€” nearly double past projections. That worst-case scenario could force a retreat from many coastal cities. "We are not saying this is definitely going to happen," David Pollard, a co-author of the new paper, told the New York Times. "But I think we are pointing out that there's a danger, and it should receive a lot more attention." 7) We also learned that humans are capable of cooperation on climate changeâ€¦ Yann Cardec/Flickr)" src="https://cdn1.vox-cdn.com/thumbor/SGFYeP7XbPFa3bmqwosad2gFSOQ=/400x0/filters:no_upscale()/cdn0.vox-cdn.com/uploads/chorus_asset/file/4618323/23464393442_974de124c7_k.0.jpg" /> (Yann Cardec/Flickr) I'm going to end this list on a somewhat hopeful note. I do think we learned something quite new about the planet â€” and the people living on it â€” in December 2015, when the world's nations gathered in Paris and struck a landmark new deal to tackle global warming. This is not to take a starry-eyed view of the deal itself. The Paris climate agreement didn't save the planet, and it hasn't solved global warming. Not by a long shot. The deal mainly adds structure and momentum to efforts already underway to reduce greenhouse gas emissions. That's a worthwhile goal in itself, but there's no guarantee it will succeed in averting drastic temperature increases. So why is it mentioned here? Because the deal marked the first time since global climate talks began 20 years ago that world leaders were able to craft a treaty committing every single country to climate action. Rather than the bitter divisions and endless backfighting that marked past conferences, cooperation ruled. It was, as I've written, a radically new approach to the problem. We'll have to see how everyone follows through. But if countries do manage to ratchet up their efforts to curtail global emissions in the decades ahead, then 2015 may mark the year we learned that humans are capable of coming together and addressing one of the most fiendishly difficult environmental problems we've ever faced.

Classmates watch in horror
<p>April 22 is Earth Day, a world holiday celebrating our home planet â€” and so far, the only one we've got. Yet we're changing the face of Earth drastically via climate change. At times, it can seem like a massive, invisible process. But it isn't invisible. In this collection of images (from NASA, unless otherwise noted) you can see the unmistakable mark that human-induced climate change is making on the planet.</p>
<p>Every year on April 22, trees are planted, litter is cleaned up, and awareness for the issues plaguing the planet are raised. In honor of the holiday, now in its 46th year, weâ€™ve gathered together 10 fascinating facts about Earth Day.</p>
It's nice to set aside a day out of the year to remember that, despite all of the imaginary borders we set up to define ourselvesâ€”our offices, neighborhoods, cities and, most importantly to many, countriesâ€”we're all spinning through space on the same blue sphere. After all, that's what will unite us when the aliens inevitably show up on the White House lawn one day. With all that in mind, for this year's Earth Day, let's check out some of the best images of our planet from space because there's nothing more sobering than the realization that all of human history is contained, as Carl Sagan would say, on a pale blue dot. NASA The EPIC Earth Named after the Earth Polychromatic Imaging Camera (EPIC), this image of our home world was snapped from NASA's Deep Space Climate Observatory satellite from about one million miles away on July 6, 2015. It showcases a fully sunlit globe that is actually a combination of different photos stitched together. NASA/Goddard/Arizona State University Earthrise Dubbed 'Earthrise,' this image was captured in October 2015 when NASA's Lunar Reconnaissance Orbiter (LRO) was 80 miles above the Moon's surface traveling 3,580 miles per hour. Despite the name of the picture, when viewed from the moon, the Earth doesn't actually rise because the moon is tidally locked, which means one side of it is always facing us. NASA/JPL-Caltech Pale Blue Dot The famous 'Pale Blue Dot' image is the first ever portrait of the Solar System. The Voyager 1 snapped this image on February 14, 1990 from 4 billion miles away. It's a great way to make yourself feel really, really small. The image is actually 60 different frames stitched together. NASA/NOAA/GSFC/Suomi NPP/VIIRS/Norman Kuring The Blue Marble NASA's Suomi NPP satellite took this image, dubbed the 'Blue Marble', on January 4, 2012. According to its researchers, the satellite was launched to "observe many facets of our changing Earth." ESA/NASA ISS Flies Over the Mediterranean ESA flight engineer Tim Peake captured this image of Earth while flying over the Mediterranean Sea on January 25, 2016. NASA Scott Kelly's Good Morning Picture During his year-long mission aboard the ISS, famed astronaut Scott Kelly took a plethora of images of Earth below. This one, which was captured on August 10, 2015, shows the Western United States. According to NASA, astronauts aboard the ISS experience 16 sunrises and sunsets every 'day.' NASA HD Sky View This image of Earth, taken by the Suomi NPP satellite after orbiting the globe six times, captures the sky above the Indian Ocean as Tropical Cyclone Joalane takes center stage. It was taken on April 9, 2015 by the Suomi NPP satellite after orbiting the globe six times. NASA/Barry Wilmore A View Of The Great Lakes From The ISS Taken by Expedition 42 Commander Barry Wilmore on board the ISS, this image shows a remarkable nighttime view of the Great Lakes on December 7, 2014. NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington False-Color Image of Earth's Plant Growth Captured by NASAâ€™s Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft sometime in 2005, this image shows Earth's plant life through infrared light. Though it's not a true colorized image like many others, this unique image captures more detail because it substitutes blue light, which our atmosphere scatters, for infrared light. It also shows something about the health of plants, since the healthiest plants reflect the most infrared light. NASA Morning Aurora Another image taken by astronaut Scott Kelly on board the ISS during his year in space captures Earth's aurora in the early hours of October 7, 2015. Kelly posted the image on Twitter saying: "The daily morning dose of #aurora to help wake you up."
