The increase in large-scale tornado outbreaks in the US doesn’t appear to be clearly linked to climate change, a new study suggests.
What, quantitatively, is the social cost of carbon dioxide—the economic damage caused by a 1-ton increase in emissions or the benefits of a 1-ton decrease?
After lying largely forgotten in a museum for decades, a set of fossilised footprints have revealed a new glimpse of the world when reptiles began taking over from amphibians as the dominant land animals.

President-elect Donald Trump has been unclear so far on how many of his campaign pledges he actually intends to see through. Hopeful Democrats and moderates have clung to this uncertainty as reason to hope that a Trump presidency wouldn’t be as bad as they feared.
The consequences of climate change are already being felt all over the globe. But some regions are particularly affected. These so-called “hotspots” are areas where strong physical and ecological effects of climate change come together with large numbers of vulnerable and poor people and communities.
The high ambition of the Paris Agreement, to limit global warming to “well below 2°C”, was driven by concern over long-term sea level rise. A warmer climate inevitably means melting ice – you don’t need a computer model to predict this, it is simple common sense.
More than a dozen authors from different universities and nongovernmental organizations around the world have concluded, based on an analysis of hundreds of studies, that almost every aspect of life on Earth has been affected by climate change.
Climate-related catastrophes are expensive, whether they come on suddenly, like the thousand-year flood in Louisiana in August 2016, or move slowly and inexorably, like desertification in Turkey.
A report based on fossilised evidence reveals that plant biodiversity in Europe and North America is changing profoundly as the world heats up.

Scientists now agree: warmer weather in the Arctic and a wavy jet stream are influencing winter weather in the UK and US.
Bolivia’s glaciers have shrunk by more than 40% in the past few decades. This puts further pressure on an already stressed water supply, while the meltwater lakes left behind risk collapsing in sudden and catastrophic outburst floods.
The destructive nature of Hurricane Matthew—which resulted in hundreds of deaths in Haiti, dozens more in the US, and extensive damage still being assessed—was a test of strength in communications systems, infrastructure, and ultimately the resilience of communities.

Southern Africa is noted for its wealth of biological diversity and for its high proportion of endemic species. These are species that are unique to a specific location and are found nowhere else in the world. Many of the region’s endemic species can be found in South Africa’s fynbos and succulent Karoo biomes.
Serious tree loss and stunted growth caused by repeated droughts in the Amazon Basin have damaged the rainforest’s vital ability to store atmospheric carbon.

If political leaders around the world are serious about gender equality, they must also get serious about climate change.
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.

An international scientific report commissioned by the UK government says the risks of climate change are comparable to those posed by nuclear conflict.
One of the most dramatic features of recent climate change is the decline of summer Arctic sea ice. The impacts of this summer ice loss on northern society, on Arctic ecosystems, and the climate both locally and further afield, are already being felt.
The goal of international climate negotiations is “to avoid dangerous atmospheric concentrations of greenhouse gases”. In 2010, Parties to the United Nations Framework Convention on Climate Change formally recognised the “long term goal” of the convention was to hold the increase in global average warming to below 2C above pre-industrial levels.
California is undergoing a record-setting drought that began in 2012, the worst in at least 1,200 years. It can be seen in many ways: most of the freshwater reservoirs are drying up, crops are wilting in the fields and groundwater is rapidly depleting.
Climate change is affecting all regions of the globe. But some places, such as Africa, are more vulnerable to climate change’s devastating effects than others. This is particularly true because of the continent’s very high dependency on agriculture.
Senior Chinese official warns that climate-related temperature rises could seriously affect the country’s harvests and major infrastructure projects.
You never forget the first time you see an iceberg. But, in truth, the first iceberg you see is likely to be small. Most icebergs that make it far enough north from Antarctica to where they are danger to shipping are sometimes many years old and at the end of their lives. They are small fragments of what once left the continent.
One of our closest animal relatives is at risk of being wiped out as changing rainfall patterns threaten to destroy its Central African habitat. Central Africa in particular, and the continent in general, is likely to be severely affected by climate change.

Those who question the seriousness of the threat which climate change presents have a very strange idea of the risks they think are acceptable.
Two new atlases provide clear visual evidence of the effect climate change and extreme weather can have on people and property.
Failure to factor immediate action on climate change into American policies and business plans aimed at economic prosperity will lead to havoc, warns former US Treasury Secretary.
If you’ve ever wondered how much little things really matter, consider the mountain pine beetle. Roughly the size of a grain of rice, the glossy black insect lives only about a year. A throng of beetles can ravage a pine as tall as an eight-story building, as the tree first oozes sap, then its needles turn rusty red...
Spring and summer have come early – and observations from some parts of the country even suggest that typical autumn events, such as the development of beech nuts and hawthorn berries, are already in evidence. But, to understand effects on our wildlife, a longer view is needed...
