In Madrid, the organisation showed a great sense of purpose. But beware a divided Europe and a US still tired of paying for the continent’s security
As Earth’s climate warms, incidences of extreme heat and humidity are rising, with significant consequences for human health. Climate scientists are tracking a key measure of heat stress that can warn us of harmful conditions.
It is vital Moscow understands that escalation will not be risk-free, and expects a proportionate response
Water vapor is Earth’s most abundant greenhouse gas. It’s responsible for about half of Earth’s greenhouse effect — the process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. Greenhouse gases keep our planet livable. Without them, Earth’s surface temperature would be about 59 degrees Fahrenheit (33 degrees Celsius) colder. Water vapor is also a key part of Earth’s water cycle: the path that all water follows as it moves around Earth’s atmosphere, land, and ocean as liquid water, solid ice, and gaseous water vapor.
Over the weekend, physical climate scientist David Holland made it to his research base on the Thwaites Glacier — a vast, unstable and vital ice formation in Southern Antarctica that researchers have scrambled to understand.
Vital United Nations climate talks, billed as one of the last chances to stave off climate breakdown, will not produce the breakthrough needed to fulfil the aspiration of the Paris agreement, key players in the talks have conceded.
When we hike through the woods, drive by a cornfield, or mow our lawns, we tend to focus on the plants: the blooming flowers, the tassel-topped stalks, and the green grass borders. But what about the dirt? It seems soil is one of the planet’s most underappreciated natural resources. Yet healthy soil is the foundation for agriculture; it also plays a vital role in protecting the air we breathe, the water we drink, the food we eat—and even our climate.
An ecological deficit occurs when the Ecological Footprint of a population exceeds the biocapacity of the area available to that population. A national ecological deficit means that the nation is importing biocapacity through trade, liquidating national ecological assets or emitting carbon dioxide waste into the atmosphere. An ecological reserve exists when the biocapacity of a region exceeds its population's Ecological Footprint.
phosphorus is biologically vital. Supplies of phosphate rock – the only major phosphorus ore – are limited. So much so that phosphorus has been listed among the “endangered elements” where there is a risk to future supply. The problem is that the phosphorus used as fertiliser ends up dissolved in rivers and oceans as soluble phosphate, eventually becoming sediment. Currently there is no economically viable way of recovering it,
