Amazon forests failing to keep up with climate change

A team of more than 100 scientists has assessed the impact of global warming on thousands of tree species across the Amazon to discover the winners and losers from 30 years of climate change. Their analysis found the effects of climate change are altering the rainforest's composition of tree species but not quickly enough to […]

Climate Change and the Elections: Five Takeaways

The results of Tuesday’s elections could have a significant influence on how the United States deals with global warming in several ways.In the Trump era, much of the action to fight climate change has been happening in the state level. On that front, the results were mixed: Several key climate policies on the ballot, including […]

6 ways ordinary people can prevent climate change, according to researchers and advocates

In October, the Intergovernmental Panel on Climate Change, a leading international body on climate change researchers, released an alarming report. The study found that countries around the world have just 12 years to reduce global warming before it reaches catastrophic levels.Now that we know time may be running out, the question is: What can we do […]

Ozone layer finally healing after damage caused by aerosols, UN says

Upper layer above northern hemisphere should be completely repaired in 2030s The ozone layer is showing signs of continuing recovery from man-made damage and is likely to heal fully by 2060, new evidence shows. The measures taken to repair the damage will also have an important beneficial effect on climate change, as some of the […]

What is climate change?

What is climate change? The planet's climate has constantly been changing over geological time. The global average temperature today is about 15C, though geological evidence suggests it has been much higher and lower in the past. However, the current period of warming is occurring more rapidly than many past events. Scientists are concerned that the […]

Climate change: Five cheap ways to remove CO2 from the atmosphere

As well as rapidly reducing the carbon dioxide that we humans are pumping into the atmosphere in huge amounts, recent scientific assessments of climate change have all suggested that cutting emissions alone will not be enough to keep global temperatures from rising more than 1.5 or 2 degrees C. The Intergovernmental Panel on Climate Change […]

Global warming may become unstoppable even if we stick to Paris target

We could be on the verge of triggering a series of cascading tipping points that result in the planet warming 4 or 5°C hotter than the pre-industrial benchmark. That, at least, is the view of a group of 16 climate scientists, who have spelled out a scenario in which sea levels would be 10 to 60 metres higher […]

Climate change: Oceans ‘soaking up more heat than estimated’

The world has seriously underestimated the amount of heat soaked up by our oceans over the past 25 years, researchers say. Their study suggests that the seas have absorbed 60% more than previously thought. They say it means the Earth is more sensitive to fossil fuel emissions than estimated. This could make it much more […]

How plants and animals are teaching scientists to fight climate change

The immensity of a program to reforest large swaths of the Amazon is hard to conceive — it aims to plant millions of trees over a remote area of Brazil roughly the size of Pennsylvania. If that wasn’t a big enough challenge, there’s also the threat seedlings face from dry spells, non-native plants and the […]

Canada passed a carbon tax that will give most Canadians more money

Last week, Prime Minister Justin Trudeau announced that under the Greenhouse Gas Pollution Pricing Act, Canada will implement a revenue-neutral carbon tax starting in 2019, fulfilling a campaign pledge he made in 2015. The federal carbon pollution price will start low at $20 per ton in 2019, rising at $10 per ton per year until […]
