As climate change threatens Australian trees, it’s important to identify which are at risk.
Climate extremes are killing Australian trees, but we don't know where they're dying. Scientists are asking the public to use their phones to help.
Monsoon clouds approach in India.
The Indian summer monsoon rainfall affects the lives of over a billion people. By looking at how prehistoric climate changes affected it, scientists can contribute to its future prediction.

Facing up to the horror of climate change can help us work towards a more sustainable culture. Young people are leading the way.
Many cities have plans in place to adapt to or mitigate the effects of climate change. But are they credible? An ongoing study looks into the question.
In the fight against climate change, cities are now seen as having a major role to play. An ongoing study examines the effectiveness of the adaptation and mitigation plans of 126 coastal cities.
The heat makes the drought even worse, because it makes the plants more thirsty so they have to drink more.

We can't make it rain. But you are already helping if you don't use more water than you need. And you can talk to your parents about the planet getting warmer, because the heat makes drought worse.
Heavy snow in Washington, DC, is an example of “weather” - not “climate”.

Australia is facing an increase in extreme heat, fire danger weather, floods and marine heatwaves, according to the latest biennial snapshot from the Bureau of Meteorology and CSIRO.
The lack of political will to meet emission targets could see more extreme flooding in the future, like what happened the Québec community of Gatineau in 2017.

Achieving climate objectives is economically realistic, but won't be possible without the support of a real transition strategy that is still lacking at all levels of government in Canada.
Coal smokestacks are seen peeking through the clouds in Kentucky. Both Canada and the U.S. need Green New Deals to help create healthy and sustainable economies that are no longer reliant on fossil fuels.
A Green New Deal would confront both climate change and social inequality. Its prospects in the United States are uncertain, but Canada should endeavour to develop one of its own anyway.

The future climate that scientists predict for the middle of the United States is one that will foster more hail events with bigger hailstones.
Climate change also has an impact on public health.
Scientists need to continue working across disciplines to find ways to disrupt disease transmission in the context of climate change.
