Forests are thought to be crucial in the fight against climate change – and with good reason. We’ve known for a long time that the extra CO? humans are putting in the atmosphere makes ...
I am wondering about the climate impact of vegan meat versus beef. How does a highly processed patty compare to butchered beef? How does agriculture of soy (if this is the ingredient) compare to grazing of beef?
The Intergovernmental Panel on Climate Change says negative emissions technologies will be needed to meet the Paris Agreement goal of limiting warming to well below 2?. In other words, just cutting emissions is not enough – we must also take existing greenhouse gases from the air.
What is the impact of temperature increases in the tropics? How likely is it that regions along the Equator will be uninhabitable due to high wet bulb temperatures such as 35? and more in places like Singapore? Do we have models that suggest how likely this is and at what time frames?
Summer and fall are wildfire season across the western U.S. In recent years, wildfires have destroyed thousands of homes, forced hundreds of thousands of people to evacuate and exposed tens of millions to harmful smoke.
As Hurricane Sally headed for the northern Gulf Coast on Tuesday, September 15, 2020, forecasters warned of a potentially life-threatening storm surge, with water levels that could rise as high as 7 feet in some areas.
What is driving the wildfires that are ravaging California, Oregon and Washington? President Trump and state officials have offered sharply different views.
Methane is a shorter-lived greenhouse gas - why do we average it out over 100 years? By doing so, do we risk emitting so much in the upcoming decades that we reach climate tipping points?
It was a grim record. On June 20 2020, the mercury reached 38°C in Verkhoyansk, Siberia – the hottest it’s ever been in the Arctic in recorded history.

Our approach to climate change for the past 30 years is simply not working. Greenhouse gas emissions in Canada in the year 2018 (the last year for which we have statistics) were almost exactly where they were in the year 2000.
As the world warms and the atmosphere becomes increasingly fertilised with carbon dioxide, trees are growing ever faster.
Seven millennia since its invention, leather remains one of the most durable and versatile natural materials. However, some consumers question the ethical ramifications and environmental sustainability of wearing products sourced from animals.
Extreme weather and climate events causing extensive damage are a fact of the Canadian climate, and this year is no exception.
Ice cores are columns of ice drilled through glaciers that are highly versatile and detailed recorders of Earth’s climate and environment that cover hundreds to many thousands of years.

Anyone who’s tending a garden right now knows what extreme heat can do to plants. Heat is also a concern for an important form of underwater gardening: growing corals and “outplanting,” or transplanting them to restore damaged reefs.
Are we headed for a period with lower Solar activity, i.e. sunspots? How long will it last? What happens to our world when global warming and the end of this period converge?

The demand for cheaper, greener electricity means that the energy landscape is changing faster than at any other point in history.

How often do you strike up a conversation with an older relative about the past? You might switch off when someone begins a sentence with “back in my day…”,

Thirty years ago, in a small Swedish city called Sundsvall, the Intergovernmental Panel on Climate Change (IPCC) released its first major report.

Hurricane Laura blew up quickly as it headed for the Louisiana coast, intensifying from a tropical storm to a major hurricane in less than 24 hours.
Thunderstorms are common across North America, especially in warm weather months. About 10% of them become severe, meaning they produce hail 1 inch or greater in diameter, winds gusting in excess of 50 knots (57.5 miles per hour), or a tornado.
Massive ice-sheets covered northern Europe and northern Asia, and about half of North America, and global sea-levels were as much as 130 meters lower than today.
