NASA and NOAA jointly reported that 2016 was the warmest year on record. That’s no surprise, as the first six months of the year were all exceptionally warm.
For the Arctic, like the globe as a whole, 2016 has been exceptionally warm. For much of the year, Arctic temperatures have been much higher than normal, and sea ice concentrations have been at record low levels.
By studying evidence of the retreat of glaciers around the globe over a period of a century, scientists believe they have found an irrefutable link to climate change.
For a period about a million years ago Greenland wasn’t covered in ice. Researchers say the discovery suggests it’s possible the ice sheet could go away again.
You probably don’t think clams are the most exciting animals on the planet. But anyone who dismisses these marine bivalve molluscs surely cannot be aware of just how important they actually are. Without knowing it, they have taught us so much about the world we live in – and how it used to be.
2016 is set to be the world’s hottest year on record. According to the World Meteorological Organization’s preliminary statement on the global climate for 2016
The bulk of methane emissions in the United States can be traced to a small number of “super-emitting” natural gas wells.
NOAA’s National Centers for Environmental Information (and several other institutions) reported April 2016 to be the warmest April on record for the planet. All of the previous twelve months now hold the “Warmest [INSERT MONTH HERE] on Record” title. That’s twelve months in a row, and that’s never happened.
2016 continues to be a momentous year for Australia’s climate, on track to be the new hottest year on record.
Senior military figures in the US warn of national and international security threats posed by the impacts of climate change.
New research confirms that increased greenhouse gas levels − rather than solar radiation impacts − are the key factor in global climate change.
Claims that the “the science isn’t settled” with regard to climate change are symptomatic of a large body of ignorance about how science works.
In the early days of the Industrial Revolution, no one would have thought that their burning of fossil fuels would have an almost immediate effect on the climate.
The perennial question of how clouds affect the Earth’s climate takes another twist, with one study expecting cooling and another the opposite.
With the help of satellite data, scientists have shown that low-level cloud cover in the tropics thins out as Earth warms. Because this cloud cover has a cooling effect on the climate, the two-degree warming target set by the Paris Agreement may arrive sooner than predicted.
The United Nations climate change conference held last year in Paris had the aim of tackling future climate change. After the deadlocks and weak measures that arose at previous meetings, such as Copenhagen in 2009, the Paris summit was different.
The State of the Climate in 2015 report, led by the US National Oceanic and Atmospheric Administration, was released. Unfortunately, it paints a grim picture of the world’s climate last year.
After warming for nearly 50 years the Antarctic peninsula has begun cooling, though probably not for long, UK scientists say.
The dip in atmospheric carbon dioxide levels during the Little Ice Age wasn’t caused by New World pioneers cutting a swathe through native American agriculture, as had been previously thought.
New mapping of one of the most remote areas in Antarctica has revealed regions deep within Earth’s largest ice sheet that are particularly prone to rapid melting.
Experts say the results of a study of ancient zooplankton fossils offer a warning about mass extinction events: There’s a tipping point, at which dramatic declines in populations begin.
Think of an Australian landscape and you’re unlikely to picture snow-capped mountains or alpine meadows. But that’s what you’ll find atop the peaks of the country’s southeastern corner.
Reconstruction of climate events long before the Ice Ages shows that failure to reduce greenhouse gas emissions could eventually lead to temperatures rising by up to 10 degrees.
The fossil fuel industry has spent many millions of dollars on confusing the public about climate change. But the role of vested interests in climate science denial is only half the picture.
Following record-high temperatures and melting records that affected northwest Greenland in summer 2015, a new study offers the first evidence linking melting in Greenland to the anticipated effects of a phenomenon known as Arctic amplification.
We’re not even halfway through the year but already you may have heard talk of 2016 being the hottest on record. But how can scientists be so sure we’re going to beat the previous record, set just last year?
New research illustrates that reactions of people, plants and animals to the changing climate are a key factor in unravelling the complexities of global warming.
Antarctica is already feeling the heat of climate change, with rapid melting and retreat of glaciers over recent decades. Ice mass loss from Antarctica and Greenland contributes about 20% to the current rate of global sea level rise.
Global temperatures for February showed a disturbing and unprecedented upward spike. It was 1.35℃ warmer than the average February during the usual baseline period of 1951-1980, according to NASA data.
Much has been written about the challenge of achieving the targets set out in the Paris climate agreement, which calls for global warming to be held well below 2℃ and ideally within 1.5℃ of pre-industrial temperatures.
Global sea level rose faster in the 20th century than in any of the 27 previous centuries, a new analysis shows.
Antarctica and Greenland may be two of the most remote places on Earth but what happens in both these vast landscapes can significantly impact on human activity further afield.
It’s official: 2015 was the warmest year on record. But those global temperature records only date back to 1850 and become increasingly uncertain the further back you go
As recently as 6,000 years ago the Sahara was green and fertile. We’ve found evidence of large rivers crossing the region, lined by flourishing settlements. Then suddenly things changed. Trees died and the land dried up. Soil blew away or turned into sand and those rivers were no more. In just a few centuries, the Sahara was transformed from a region similar to modern South Africa into the desert we know today.
The Paris climate conference will set nations against each other, and kick off huge arguments over economic policies, green regulations and even personal lifestyle choices. But one thing isn’t up for debate: the evidence for climate change is unequivocal.
The idea that global warming has “stopped” is a contrarian talking point that dates back to at least 2006. This framing was first created on blogs, then picked up by segments of the media – and it ultimately found entry into the scientific literature itself.
There are many ongoing signs that the planet is heating up, even “on fire.” In the western region of North America, the prolonged drought has led to high temperatures and many wildfires, from Canada and the Northwest earlier this summer to California more recently.
Wouldn’t it be great if scientists could make their minds up? One minute they’re telling us our planet is warming up due to human activity and we run the risk of potentially devastating environmental change.
National and international studies have shown that the Earth is warming, and with this warming, other changes are occurring, such as an increasing incidence of heat waves, heavy downpours and rising sea levels.
What will the weather be like next week, next season, or by the end of the century? In the absence of a second Earth to use in an experiment, global weather and climate model simulations are the only tools we have to answer these questions.
Antarctica’s glaciers have been making headlines during the past year, and not in a good way. Whether it’s a massive ice shelf facing imminent risk of collapse, glaciers in the West Antarctic past the point of no return, or new threats to East Antarctic ice, it’s all been rather gloomy.
People living across the US have lived through some odd weather in the past year. It’s been unusually warm and dry in the western US, while the East had a very cold and snowy winter. Meanwhile, scientists have been seeing Pacific marine species in places they’re not normally found and a huge spike in hungry, stranded sea lion pups on California shores.
The biggest extinction ever known on Earth resulted from oceans turned acid by CO2, the main gas driving human-caused climate change today.
Fish accustomed to shallow northern waters will search in vain for cooler depths as climate change warms the seas where they thrive.
If you’re younger than 30, you’ve never experienced a month in which the average surface temperature of the Earth was below average. Each month, the US National Climatic Data Center calculates Earth’s average surface temperature using temperature measurements that cover the Earth’s surface.
At first glance, asking whether global warming results in more snow may seem like a silly question because obviously, if it gets warm enough, there is no snow. Consequently, deniers of climate change have used recent snow dumps to cast doubt on a warming climate from human influences. Yet they could not be more wrong.
When you ask yourself what the biggest unanswered scientific questions are, “how did sea levels change over the past 100 years?” is unlikely to appear at the top of your list. After all, haven’t we already figured that out? It turns out that obtaining a complete picture of how our oceans have been changing is not a simple task, yet is vital for making future projections.
The most detailed study yet of the Greenland ice sheet illustrates the complex process that is causing billions of tonnes to melt ever year.
2014 has been confirmed as Australia’s third-hottest year, capping off a record-breaking decade, according to the Bureau of Meteorology’s annual climate statement, released today.
The Japan Meteorological Agency (JMA) has announced that 2014 was the hottest year in more than 120 years of record-keeping — by far. NOAA is expected to make a similar call in a couple of weeks and so is NASA.
In the wake of a Missouri grand jury’s decision not to indict Darren Wilson, the police officer who shot and killed Michael Brown, it can be difficult to imagine a place where law enforcement and a racially diverse population work together productively in the United States.
For several years now climatologists have puzzled over an apparent conundrum: why is Antarctic sea ice continuing to expand, albeit at the relatively slow rate of about one to two percent per decade, while Arctic sea ice has been declining rapidly?
Reduced monsoon rainfall and increased river flow are two extremes that new research has linked to man-made impacts on climate caused by air pollution.
The exotic lionfish, already a long way from the reefs of its Indo-Pacific home, is heading further north up the US coast as global warming causes big changes to ocean habitats.
New scientific research confirms that global warming is melting increasingly larger areas of Arctic sea ice − and reducing its vital function of removing CO2 from the atmosphere.
Here’s an historical tidbit you may not be aware of. Between the years 1860 and 1940, as the number of Methodist ministers living in New England increased, so too did the amount of Cuban rum imported into Boston – and they both increased in an extremely similar way. Thus, Methodist ministers must have bought up lots of rum in that time period!
Scientists simulating changes in mountain glaciers over the last century and a half have established that rates of melting have increased greatly in recent years – and that humans are the main culprits.
Dire warnings of imminent human-induced climate disaster are constantly in the news but predictions of the end of the world have been made throughout history and have never yet come true.
The newly released National Climate Assessment spans 30 chapters with thousands of references on how climate change is impacting the U.S. The report took more than 300 scientists and 4 years to prepare, including addressing more than 4,000 comments from the public. The message of the report is that climate change is already happening across the country.
Parts of ancient Antarctica were as toasty as today’s California coast, say scientists who used a new method to measure past temperatures. The study focused on Antarctica during the Eocene epoch, 40 to 50 million years ago, a period with high concentrations of atmospheric CO2 and consequently a greenhouse climate.
If wealth and income weren’t already so concentrated in the hands of a few, the shameful “McCutcheon” decision by the five Republican appointees to the Supreme Court wouldn’t be as dangerous. But by taking “Citizen’s United” one step further and effectively eviscerating campaign finance laws, the Court has issued an invitation to oligarchy.
It’s being billed as “the biggest story of our time.” This weekend viewers of Showtime, the US cable channel, will be watching the first of an nine-part documentary series on climate change: some of the biggest names in Hollywood are involved.
Can the U.N. Intergovernmental Panel on Climate Change most recent report or a star-studded Showtime mini-series change the way people talk and think about climate change? Katharine Hayhoe urges her fellow climate scientists to ramp up their messaging game.
Warming in the Arctic has now reached the northernmost sections of the Greenland ice sheet. After a long period of stability (more than 25 years), we have found in a new study of the region that the northeast section of the ice sheet is no longer stable. This means global sea levels may rise even faster than was previously anticipated.
Ice in the Arctic continues to retreat. It’s long been established that Arctic ice is on the retreat but it’s the pace of change that’s surprising scientists: latest studies show the region is at its warmest since 40,000 years.
The head of the World Meteorological Organization tells Climate News Network there is no standstill in global warming, which is on course to continue for generations to come.
The United States is currently engaged in secret negotiations on the Trans-Pacific Partnership (TPP), a multinational trade agreement with the goal of liberalizing trade among a dozen or so countries that border on the Pacific Ocean.
First it was Wisconsin. Now it’s North Carolina that is redefining the term “battleground state.” On one side: a right-wing government enacting laws that are changing the face of the state. On the other: citizen protesters who are fighting back against what they fear is a radical takeover.
U.S. carbon dioxide emissions related to energy increased in 2013 for the first time in three years, possibly the first sign that a trend in declining emissions from energy consumption has ended for now. The U.S. Energy Information Administration released a report on Monday showing that 2013 energy-related CO2 emissions in the U.S. are expected to have increased 2 percent over 2012 emissions once all the data for the year are tallied.
For almost forty years Republicans have pursued a divide-and-conquer strategy intended to convince working-class whites that the poor were their enemies. The big news is it’s starting to backfire.
A corner of the USA forever linked with the name of one of America’s foremost naturalists is changing as the temperature rises. Walden Pond’s familiar vegetation is not what it was in Thoreau’s day.
For years political scientists have wondered why so many working class and poor citizens of so-called “red” states vote against their economic self-interest. The usual explanation is that, for these voters, economic issues are trumped by social and cultural issues like guns, abortion, and race.
Far below the surface, the waters of south-east Asia are heating up. A region of the Pacific is now warming at least 15 times faster than at any time in the last 10,000 years. If this finding – so far limited to the depths where the Pacific and Indian Oceans wash into each other – is true for the blue planet as a whole, then the questions of climate change take on a new urgency.
The world may be warming more than twice as fast as thought because some key data has been overlooked, two scientists argue. But others think seasonal changes in the Pacific have led to an over-estimate of the warming.
An end to greenhouse gas emissions is possible by 2050, a report finds. But a decade before that, other researchers say, the world is set to cross a fateful threshold.
An old friend who has been active in politics for more than thirty years tells me he’s giving up. “I can’t stomach what’s going on in Washington anymore,” he says. “The hell with all of them. I have better things to do with my life.” My friend is falling exactly into the trap that the extreme right wants all of us to fall into
Rep. Alan Grayson (D-CA) found himself on Tuesday being added to the list of things that had been shut down because of Republicans in Congress.
In his complaints against the wing of the Republican Party that engineered the present government shutdown, Senate Majority Leader Harry Reid derided his opponents as “Tea Party anarchists.” It’s hard to decide who should be more annoyed — the Tea Party or the anarchists.
As a child I was bullied by bigger boys who threatened to beat me up if I didn’t give them what they wanted. But every time I gave in to their demands their subsequent demands grew larger. First they wanted the change in my pocket. Next it was the dessert in my lunchbox. Then my new Davy Crockett cap. Then the softball and bat I got for my birthday.
This week’s government shutdown has consequences for all of us, costing an estimated $300 million each day that the government is closed for business. Many Americans have voiced their frustrations with the fallout from the shutdown on Facebook, Instagram, and Twitter using the hash tag #DearCongress.
This week on Moyers & Company in a rare television interview, Bill talks to visionary, author and farmer Wendell Berry to discuss a sensible, but no-compromise plan to save the Earth. Wendell Berry, one of America’s most influential writers who has written more than 40 novels, books of poetry, short stories and essays, has become an outspoken advocate for revolution.
Widening inequality thereby ignites what the historian Richard Hofstadter called the “paranoid style in American politics.” It animated the Know-Nothing and Anti-Masonic movements before the Civil War, the populist agitators of the Progressive Era and the John Birch Society
Boehner ushers a bill through the House that continues to fund the government after September 30 but doesn’t fund the Affordable Care Act. Anyone with half a brain knows Senate Democrats and the President won’t accept this — which means, if House Republicans stick to their guns, a government shut-down.
Congress will reconvene shortly. That means more battles over taxes and spending, regulations and safety nets, and how to get the economy out of first gear. Which means more gridlock and continual showdowns over budget resolutions and the debt ceiling.
Climatologists are puzzled that greenhouse gas emissions continue unabated, while the atmosphere is warming more slowly than they expected. Now two scientists in the US think they know why. hey say cooling waters in the tropical Pacific Ocean have played a large part in slowing recent warming, a finding which challenges those who argue that the slowdown means climate change is not as serious a problem as most climate scientists are convinced it is.
Rachel Maddow reports on North Carolina's success in improving voter turnout and ease of voting through the 2008 election and the sudden change in direction (and ruling party) when wealthy Republican backer, Art Pope, turned the tide in 2010 allowing a Republican take-over of the state government and a wave of regressive legislation, including voter suppression.
Bill talks with author and New York Times journalist Mark Leibovich about his latest book, This Town, in which he writes that money rules D.C., and status is determined by who you know and what they can do for you. Mark Leibovich covers Washington, D.C., as chief national correspondent for The New York Times Magazine.
They carried signs that demanded “Voting Rights,” “Jobs for All” and “Decent Housing.” They protested the vigilante killing of an unarmed black teenager in the South and his killer’s acquittal. They denounced racial profiling in the country’s largest city.

British scientists say estimates of the amount of iron dissolving into seawater around some of the world’s coasts may be drastically wrong. They say there is no standard, one-size-fits-all way to measure how much iron enters the water in different parts of the globe. Instead, they say, the amounts may vary by up to ten thousand times between one area and another, with profound implications for the impact of the iron on the oceanic carbon cycle.
Greenland’s icesheet is melting, at the surface and at its base. Don’t worry: it isn’t global warming that is thawing the base of the Greenland ice cap. It is just the normal warmth of an active rocky planet.
Marine species are leaving waters near the Equator and heading for cooler seas nearer the poles ten times faster than creatures which live on land, scientists have found.
Melting permafrost is one of those "wild cards" that might define a runaway climate tipping point. Permafrost is mainly frozen "old" vegetation from a time when the world was much warmer.
The melting of the Arctic icecap has become so fast and so certain that researchers can now confidently predict when the ocean will become ice-free, to within four years.
New research shows that glaciologists still cannot say for certain whether the Earth’s north and south polar ice is melting faster as the years pass.
The forensic search for the mysterious agent that almost melted Greenland goes on. The latest suspect to be rounded up for questioning is the jet stream, according to scientists in Sheffield, in the UK.
On both sides of the Atlantic scientists studying lakes have discovered they are warming – and this is bad news both for water quality and the fish. The Alpine lakes of Austria are warming up. By 2050, their surface waters could be up to 3°C warmer, according to new research in the journal Hydrobiologia.
New study predicts a big jump in foliage growth in arid regions as carbon dioxide levels increase.Australian scientists have solved one piece of the climate puzzle. They have confirmed the long-debated fertilization effect.
Indications the rate of warming in oceans is greater than previously thought. Now scientists are using data collected during the Challenger’s four year expedition to try to understand the heat content of the oceans.
