Feeling the heat?🔥 Extreme heat is the deadliest extreme weather.
 
An estimated 546,000 people die from heat each year, 63% more than in the 1990s. 

The costs go beyond health. Heat triggers wildfires, strains power grids, disrupts transport and food supplies and pushes up the cost of energy and food. 
 
Heat affects us all. Transitioning away from fossil fuels limits the impact and heat-health warning systems can save lives – up to 100,000 a year according to World Health Organization

Rising temperatures mean rising risks for pregnant women, who are among the most vulnerable groups. Extreme heat is linked to premature birth, low birth weight, stillbirth and maternal complications.
 
A newly released report from Wellcome Trust shows the health risks of extreme heat on maternal, fetal and newborn health.  
 
What the data shows: 
73% of maternal health professionals surveyed across five countries and five continents say heat-linked cases or complications have increased in the past five years 
81% are concerned or very concerned that extreme heat will increasingly put maternal, fetal and newborn health at risk. 
 
Decades of progress on maternal and newborn health are now at risk, as climate change - driven by the burning of fossil fuels - makes extreme heat more frequent and intense.  
 
Speaking in Fiji at , UN Climate Change Executive Secretary Simon Stiell said: “As extreme heat worsens, pregnancy and birth are now a new faultline in the global climate crisis... This faultline must not become another deep chasm of climate-driven suffering, inequality and injustice.”

As momentum for in Türkiye builds, this week all eyes are turned to the Pacific as Tuvalu, Fiji and Australia are partnering for . 
 
Government leaders, country delegates and experts will discuss topics such as access to climate finance, the ocean-climate connection and curbing global heating. 
 
This last major meeting ahead of COP31 in November in Antalya brings Pacific voices to centre stage.

A UN report has confirmed what some coastal communities are already feeling – the ocean is rising faster than any point in recorded history.

Human-caused climate change is making our ocean warmer. It is absorbing about 91% of the heat caused by global warming. When water heats up, it expands and takes up more space. This, and melting glaciers and ice sheets, is causing seas to rise at record pace – 5.9mm in 2024 alone, up from an average 4.7mm between 2014-2023.

Next week, Pre-COP takes place in Tuvalu and Fiji, bringing leaders, country delegations and experts to one of the regions most affected by sea level rise. The Pacific region is at the frontline of the climate crisis, the single largest threat to the lives, livelihoods, culture and security of Pacific communities.

Fiji, Tuvalu and Australia are partnering to host this preparatory meeting ahead of COP31 in November putting Pacific voices and Pacific-led solutions in the spotlight.

The facts are clear: the choices we make now will determine how well we can protect communities and economies around the globe.

Every year food loss and waste costs the global economy roughly US$1 trillion. And the cost of this problem goes beyond finances, it is one of the biggest solvable drivers of climate change.

Every year, food loss and waste contributes to between 8-10% of greenhouse gas emissions.
When food ends up in the bin it rots and releases methane, a powerful greenhouse gas that traps more heat than carbon dioxide.

When we waste food we waste everything it took to make that food; water, energy, land and labour.

The good news is cutting our food waste means
✅Cheaper grocery bills
✅Lower greenhouse gas emissions
✅Less pressure on land and water

Reducing food waste is a climate solution we cannot afford to ignore.

Wild news: protecting tigers helps fight climate change. 🐾

Here’s how it works:
🐅 Tigers hunt deer and other animals which feed on plants
🌱Fewer plant-eaters gives forests the chance to grow thicker
🌳Thicker forests store more carbon – helping fight climate change

Scientists have put a number on it – forests with tigers are linked to 28% more CO2 removal than forests without tigers.

And it's not just tigers – it's whales carrying nutrients, elephants spreading seeds and bison grazing that helps grasslands grow back. Wild animals everywhere are quietly helping regulate to our climate.

Scientists worldwide now agree: protecting wildlife is a critical part of fighting climate change.

Water knows no borders. It is our most valuable shared resource. 💦

And it is threatened by climate change.

Glaciers continue to retreat and rivers are running dry. 2025 was one of the driest years for our rivers in 35 years, as new data by World Meteorological Organization - WMO shows.

Water is our greatest shared resource. In protecting it we protect ourselves.

“The climate crisis is accelerating – but so are the solutions.”

United Nations Secretary-General António Guterres addressed leaders at the UN Climate Summit 2026 in New York with an urgent call to action:

“We have seen how fossil fuel dependence wreaks havoc – driving up costs, draining budgets, squeezing households. And leaving countries at the mercy of conflicts and decisions far beyond their borders.

We must match an accelerating crisis with accelerating action.”

The solutions are clear: transitioning away from planet-heating fossil fuels and strengthening resilience, especially for the most affected and the most vulnerable.

In the Secretary-General’s words: “Renewables are the cheapest, fastest, and most secure source of new electricity almost everywhere. Clean energy has gone from alternative to unstoppable.

Without adaptation, droughts become hunger crises; storms become debt crises; and heatwaves become killers.

We are the first generation with the tools to end the fossil fuel age – and the last who can avert climate catastrophe.”

Ever wondered what difference global collaboration under the United Nations can make?

👉 A huge one.

Take the ozone layer: Nearly 40 years ago, countries united under the Montreal Protocol on Substances that Deplete the Ozone Layer. Since then, ozone-depleting substances, which are also powerful greenhouse gases, have been cut by 98% worldwide.

Joining forces for a common goal is our most powerful tool to tackle the climate crisis.

We have done it before. We can do it again. If we all work together.

in Baku has wrapped up!

The week brought together governments, businesses, cities, Indigenous Peoples, local communities, international organizations and civil society to show how climate action has now entered the era of implementation.

From Climate Week through to and beyond, we must drive the promise of the Paris Agreement further and faster.
