Pushing the needle back on billowing carbon dioxide emissions may be necessary to avoid catastrophic warming
. But for those who are squeamish about drastically engineering the climate by seeding algae blooms or spraying aerosols to form clouds, ...
Each year there are more extreme weather events not only in the US but all over the world. Most scientists agree that, as more carbon dioxide is pumped into the air and the gaseous composition of the atmosphere is changed, extreme weather events ...
In the 19th century, as land-hungry pioneers steered their wagon trains westward across the United States, they encountered a vast landscape of towering grasses that nurtured deep, fertile soils.
Today, just three percent of North ...
Tim Kruger organized a conference on technologies to extract greenhouse gases from the atmosphere.
The world’s leading advocates -- and sceptics -- of sucking carbon dioxide out of the atmosphere to solve global warming
gathered this ...
As you squeegee out your basement, replace your blown-off roof tiles, bury your heat-withered tomato crop and think about moving to a house on higher ground, you will be forgiven if you want to step out onto the street, tilt your head toward ...
A gigantic, steaming-hot mound of compost is not the first place most people would search for a solution to climate change, but the hour is getting very late. "The world experienced unprecedented high-impact climate extremes during the 2001-2010 ...

Climate scientists may have to rethink some of their old assumptions about carbon. US and European researchers have just established that black carbon, soot and biochar
-- the burnt remains from countless forest fires -- doesn't stay in the soil ...
As the realities of global
climate change become ever more alarming, advocates of technological approaches to "geoengineer" the planet's climate are gaining a following.
But the technologies that are promoted -- from spraying sulphate ...
To hear some of its proponents talk, the substance known as biochar
-- a form of charcoal made from logging and agricultural waste -- has properties that verge on the magical. It not only cuts down dramatically on the carbon emissions that cause ...
“About 74,000 years ago,” Lynas began, “a volcanic event nearly wiped out humanity. We were down to just a thousand or so embattled breeding pairs. We’ve made a bit of a comeback since then. We’re over seven billion strong. In half a million ...
Soils store three times as much carbon as plants and the atmosphere. Soil organic matter such as humus plays a key role in the global
carbon cycle as it stores huge amounts of carbon and thus counters global warming
. Consequently, the Kyoto ...

IT'S maddening. We have brilliant renewable energy resources, brilliant innovators and a vast pool of superannuation savings looking for opportunities beyond our overvalued, over-analysed, ticket-clipped top 50 listed companies.
We also ...
It seems modest, as power plants go -- a 29-megawatt facility, situated just north of the Vermont-Massachusetts line, that will burn woody biomass to generate enough power for 25,000 to 30,000 homes. But like many proposed plants in the recently ...
Sadly, as the threat of climate change worsens, U.S. lawmakers move further away from practical solutions.
Last week, NASA reported that 2010 was the second hottest year on record, capping the warmest decade in modern times. Climate ...
THIS is a turbulent time in which a confluence of events has created concern for the very survival of the planet in terms of human habitation as well as other life forms.
This concern may or may not be well-founded and there are deniers ...

Symposium to focus on climate change and the future of western forests
Former Vice President and Nobel laureate Al Gore will join forest scientists and policy makers at a February ...
It has an appealing symmetry to it: If we got ourselves into this climate mess by digging up and burning coal, maybe we can fix it by creating some more coal and putting it back into the ground.
That very idea, involving the ...
The main cause of climate change is the burning of fossil fuels, so why are billions of dollars being invested to find and produce more oil, coal and natural gas?
That is the question posed by Canadian indigenous representatives at the ...
