Global average sea level has risen by about 17 cm between 1900 and 2005. This is a much faster rate than in the previous 3,000 years. The sea level changes for several reasons, including rising temperatures as fossil fuel
Every time you flush your toilet or drain the bath, you’re losing something surprisingly valuable: heat. It takes a lot of energy to warm up the water in the first place, and vast amounts of this energy simply disappear down and is lost in the environment.
Many regions of the United States are struggling with water shortages. Large areas of the West are contending with moderate to severe drought, while California is now in the fifth year of one of the most extreme droughts in its history. Even non-arid regions, such as the Southeast, are not exempt from water shortages.
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.
Much of the U.S. was built around the automobile, with greater distances to be covered than in places like Europe, making Americans' daily lifestyles higher in energy than elsewhere.
The National Renewable Energy Laboratory this week said that rooftop solar panels have the potential to generate nearly 40 percent of electricity in the U.S. But what about the cost of going solar?
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.

By many accounts, the spread of solar power is unstoppable. Costs continue to fall at a blistering pace, solutions to give consumers a solar-powered home without needing to connect to the grid for back-up power are emerging, and even the
When you cut and burn a tropical forest, you’re left with a barren plain of cracked red mud, incapable of supporting life – the opposite of the teeming, hyperdiverse array of life that was destroyed. Once the trees are gone, the nutrients wash away and the soil degrades into a dense, brick-like layer so hardened that plant roots can’t get through it.
The international community has been negotiating on climate change since 1989, but the Paris Agreement marks a real step forward. It aims to accelerate a move away from fossil fuels to mitigate global warming and to help vulnerable countries adapt to the effects of climate change, and reflects a clear recognition of the urgency of the task.
Despite robust global economic growth over the past two years, worldwide carbon emissions from fossil fuels grew very little in 2014, and might even fall this year.
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

A slowing economy and falling energy demand, plus concerns over air pollution, spur Beijing to halt new coal mines and close hundreds of existing operations.
How did we get to where we are now? “Free range” capitalism could be the explanation for climate change, and needs taming, says one writer.
The Paris agreement was a diplomatic triumph. The nations of the world spoke with one voice of their desire to limit the damage of climate change. But there is a distinct disconnect between the ambition and the action required to achieve that goal.
Southern Africa has been experiencing high temperatures in recent months. In October, Zimbabwe experienced a heatwave with temperatures in Kariba reaching 45°C.
Despite what the doubters say, a low-carbon economy is not only possible, it makes economic sense.
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 UN climate talks in Paris have ended with an agreement between 195 countries to tackle global warming. The climate deal is at once both historic, important – and inadequate. From whether it is enough to avoid dangerous climate change to unexpected wins for vulnerable nations, here are five things to help understand what was just agreed at COP21.
At the Paris climate summit, delegates have struck an agreement that calls for the world to “hold the increase in the global average temperature to well below 2℃ above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5℃”.
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.
Climate science has been instrumental in developing the ambitious carbon emission reduction targets negotiated at the recent climate talks in Paris. At the same time, the kinds of actions needed to avert the worst effects of climate change demand new ways of engaging that go far beyond science and formal diplomacy.
Discussions at the Paris climate talks took place within incredibly narrow parameters. In fact, it would not be too great an exaggeration to say that the summit’s main purpose is to send the private sector a message about which way it should steer its future investments.
The world’s soils could be a key ally in the fight to limit global warming to 2℃, thanks to their ability to store carbon and keep greenhouse gases out of the atmosphere.
Coal, oil and gas sectors warned that trillions of dollars of assets could be stranded if a global agreement on limiting climate change is reached at the UN summit in Paris.
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.

French wine lovers have always taken their soil very seriously. But now the country’s government has introduced fresh reasons for the rest of the world to pay attention to their terroir.
The world is watching as refugees flood into a Europe unprepared for the new arrivals. Conflict and social unrest due in part to climate stress – including induced food shortages and social conflict – have prompted migrants to search for new homes and new opportunities. To ecologists, however, this comes as no surprise.
Ask people what they know about Antarctica and they usually mention cold, snow and ice. In fact, there’s so much ice on Antarctica that if it all melted into the ocean, average sea level around the entire world would rise about 200 feet, roughly the height of a 20-story building.
This week, scientists registered their concern that super-warm conditions are building to a point where corals are severely threatened across the tropical Indian, Pacific and Atlantic oceans. They did so after seeing corals lose colour across the three major ocean basins – a sign of a truly momentous global change.
If we can convince people that climate change is real and important, then surely they will act: this intuitive idea underlies many efforts to communicate climate change to the public.
Scientists report that the great oceanic “lung” is again breathing in vast amounts of carbon dioxide from the atmosphere – but can’t say why or whether it will last.
There are two extremes in the debate over capitalism’s role in our present climate change problem. On the one hand, some people see climate change as the outcome of a consumerist market system run rampant. In the end, the result will be a call to replace capitalism with a new system that will correct our present ills with regulations to curb market excesses.
Ethiopia and Morocco praised for pledges on reducing greenhouse gases that are far more ambitious than those of China and Canada.

Democrats (myself included) enjoy ridiculing Republicans who deny the scientific consensus behind climate change. But we then deny the inconvenient truth behind our own preferred climate policies: they will have regressive impacts on the poor and middle class.
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.
You may have read recent reports about huge changes in sea level, inspired by new research from James Hansen, NASA’s former Chief Climate Scientist, at Columbia University. Sea level rise represents one of the most worrying aspects of global warming, potentially displacing millions of people along coasts, low river valleys, deltas and islands.
People cannot engage in something they cannot see or feel. We need concrete reasons to care and act. In this way, climate change presents a threefold intangible challenge:
