But with new commitments getting made by governments all over the world, we hope to see this progress improve soon.
The Little Ice Age brought some bitter extremes.
Pieter Bruegel the Elder, 1565
Globally, the temperature changed by half a degree Celsius, but it dramatically altered the likelihood of extreme local weather.
Evidence connects human-caused climate change to heat waves. Ties to some other extremes aren’t as clear cut.

Not every extreme weather event is caused by climate change, but heat waves that were once ridiculously improbable are showing up more often. Just ask Portland.

Extreme heat warnings can help change our dangerous relationship with hot weather.
The two leaders ignored the most pressing global issue to concentrate on the status quo issues of security and arms control.
Mitigating climate change is more politically popular than adapting to its inevitable effects.
If the G7 is serious about stopping global warming, it could start by acknowledging who and what is causing it.
One cold winter doesn’t negate more than a century of global warming. We need the political leadership to set the world on a safer path. Ill-informed tweets by government senators won’t help.
New research looked at wave conditions over the past 40 years, and found wave power has increased since at least the 1980s, mostly in the Southern Hemisphere.
Climate change literacy is key.
There are significant gaps in what teachers in Ghana know about ozone depletion and climate change, even though these subjects are in the science curriculum.

Climate change has profound, but often overlooked, consequences for human health.
New findings suggest the loss of fertility at high temperatures is a major threat to the survival of some species.
This Warty Pig is part of a panel dated to more than 45,500 years in age.

The ancient cave paintings have only begun to tell us about the lives of the earliest people who lived in Australasia. The art is disappearing just as we are beginning to understand its significance.
A future of heat and strife or humanity’s finest hour – our response to climate change today will define the 21st century.
A holistic view of climate change risk considers climate hazards, exposure, vulnerability and the responses to these. It also takes into account how multiple risks interact.
Humanity can still limit global warming to 1.5°C this century. But political action will determine whether it actually does. Conflating the two questions amounts to dangerous, misplaced punditry.
Our research looked at deaths in Australia between 1968 and 2018. While more people tend to die in winter than summer, this gap is narrowing – and that’s a worry.
For the first time, political will and global public opinion seem focused on profound climate action. This decade will be a decisive one.
