Absolute temperatures are expected to rise more slowly in the tropics than in higher latitudes and polar regions, but the combination of heat and rising humidity will make life more challenging.
The "winners" evolved in the warm, subtropical regions. Those that evolved in cooler temperate ecosystems – the "losers" – risk becoming extinct.
A school of convict tang (
Acanthurus triostegus) swim on Kiritimati’s dead reefs after the 2015–16 marine heatwave.
Reef fish vanish during marine heat waves, but may bounce back quickly on reefs that have few other environmental stressors.
If coffee and wine are things you love, then you need to pay attention to climate change.
People tend to pay attention when things get personal, so you need to know how climate change is damaging things in your life.

Heatwaves can cause a large number of deaths, especially when vulnerable groups are unprepared and are not acclimatised to hot temperatures.
Despite the prevalence of Fairtrade sugar in UK society, the sugarcane industry remains deeply troubled.
Koalas are stressed out by a range of pressures, from habitat loss to dog attacks.
Ever feel so stressed you can't carry on? You're not alone - koalas have a similar problem, and hundreds are being rescued by veterinarians each year.
A global temperature rise of 1.5℃ above pre-industrial levels could have devastating consequences for city dwellers.
Some materials and surfaces radiate much more heat (red areas) than others, as can be seen in this thermal image of Arncliffe Street in Wolli Creek, Sydney.
Hot spots occur at the scale of where people live – the building, the street, the block – which means urban design and building materials have profound implications for our health and well-being.
Health issues from extreme heat are a reality for many in Africa.
Africa must find ways of dealing with extreme heatwaves or suffer a range of health problems, including fatalities.
For every death there’ll be many more hospital admissions for things such as strokes and heart attacks.
Most people are acutely aware of the toll the heat can take on human life. So it may come as a surprise that more Australians die from the cold than the heat.
