What 500-year-old Clams Can Tell Us About Climate Change

What 500-year-old Clams Can Tell Us About Climate ChangeYou 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.

Why Global Warming Started Earlier Than We Thought

Why Global Warming Started Earlier Than We ThoughtIn 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.

How We Predict When Antarctica's Melting Ice Sheets Will Flood The Seas

The Totten Glacier calving front. Esmee van Wijk/CSIROAntarctica 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.

What Are Climate Tipping Points And How They Could Suddenly Change Our Planet

What Are Climate Tipping Points And How They Could Suddenly Change Our PlanetAs 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.

Why The Global Warming Pause Was A Myth All Along

Why The Global Warming Pause Was A Myth All AlongThe 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.

Global Warming Hiatus Appears To Be A Myth

Global Warming Hiatus Appears To Be A MythNational 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 Is That Warm Blob In The Pacific Ocean?

What Is The Warm Blob In The Pacific Ocean?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.

Does Global Warming Mean More Or Less Snow?

snow stormAt 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.

How Have Sea Levels Changed Over The Past 100 Years?

How Have Sea Levels Change Over The Past 100 Years?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.

Clearing Up Confusion Between Correlation And Causation

Clearing Up Confusion Between Correlation And Causation

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!

Climate Change In The U.S. In 8 Compelling Charts

climate charts

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.

Antarctica Was Once As Warm As California

Antarctica Was Once As Warm As California

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.

Greenland Ice Sheet Is Melting At An Accelerating Rate

Greenland Ice Sheet Is Melting At An Accelerating Rate

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.

North Carolina Is The Newest Battleground State

North Carolina Is The Newest Battleground State

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.

After Declining From Slumping Economy, U.S. Energy Related CO2 Emissions Increased in 2013

 After Declining From Slumping Economy, U.S. Energy Related CO2 Emissions Increased in 2013

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.

Deep Oceans May Be Storing More Heat And Giving Us Time To Act But Time Is Short

Indian Ocean Warming

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.

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

Cooler Pacific Has Slowed Global Surface Temperature Rise

Cooler Pacific Has Slowed Global Surface Temperature Rise

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.

Ocean Iron Differs Substantially Between Locations

Ocean Iron Study Means Climate Rethink

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.
