New Zealand can expect more days above 25℃, the threshold for heat stress in livestock, and fewer frost days, which will affect crops like kiwifruit that need winter chilling.
Such a dramatic rise in extreme heat days is not inevitable. If global warming is limited to 1.5℃ this century, Western Sydney will have fewer than 17 days of 35℃ per year.

Dogs can only sweat on their paw pads, which is not a lot of use when it comes to shedding body heat.

The way we build our cities is adversely affecting our health, and, in particular, our hearts. Thinking of urban planners as health professionals could change that
As the climate changes and heatwaves become more frequent and severe, it’s vital we do more to understand who is most vulnerable and how we can reduce their risk.
Cities occupy just 3% of the Earth’s surface, yet more than half the world’s population live in urban environments. We need nation-wide plans to keep our cities cool so no one gets left behind.
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.

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.
