The US president has announced executive actions to tackle climate change, but stopped short of declaring a formal emergency. The move coincides with heat waves battering the US and Europe.

Earlier this month, India's northwest sweltered under a heatwave that came unusually early. Every year, hundreds of people die during heatwaves in India and the country usually also suffers severe water shortages. There are fears that because of climate change, heatwaves are coming earlier and may be more severe. Nagraj Adve, a climate activist and author of "Global Warming in the Indian Context", tells us more.

As climate change continues to take effect, we are all going to have to change the way we behave in order to survive. That's the conclusion of Eric Klinenberg, a professor of social science at New York University who's written a book focusing on the extreme 1995 heatwave in Chicago. Temperatures there hit over 41°C, killing hundreds of people. Klinenberg says it's not just infrastructure that will have to change, but the whole way we interact with our families and those living around us.

Spain is on alert for wildfires as a heatwave that has enveloped southeastern Europe in recent days shifts west. Temperatures are forecast to reach highs of around 40 degrees Celsius (104 degrees Fahrenheit) in much of the Iberian peninsula in the coming days. As firefighters try to extinguish a fire in Tarragona, forestry agents try to prevent a new fire from breaking out near Barcelona amid the worst heat wave in nearly 20 years.

Residents of the southern Portuguese city of Evora seek shade and other ways to cool down as temperatures hit 40 degrees.

As the southern European nation battles hundreds of wildfires, Prime Minister Mitsotakis has warned that the country is facing its worst heat wave for 30 years. Extreme weather in 1987 claimed more than 1,500 lives.

Tourist attractions close in Athens as temperatures soar during one of the worst heatwaves the country has seen in decades. The intense heat has led to deadly wildfires in the region, with nearby Turkey suffering its worst fires in at least a decade.

The US National Weather Service has said the heat wave "will likely be one of the most extreme in recorded history" for parts of the region, as people are warned to take precautions against "life threatening" heat.

Hundreds seek shelter at a cooling center in Portland, Oregon's biggest city, to escape one of the state's hottest heat waves on record. Portland hit 45°C (114°F) on Monday according to the US National Weather Service (NWS), breaking back-to-back records set over the weekend.

Over 90% of the small town town in British Columbia was destroyed, prompting the evacuation of over 1,000 people. Prior to the fire, Lytton had seen three consecutive days of record high temperatures.

Coroners are investigating a surge in sudden deaths in British Colombia. Around 100 more people than usual have died over a four-day period as temperatures reached nearly 50 Celsius.

Humans have destroyed about two-thirds of the world's original tropical rainforest and in the process destroying the natural buffer against climate change. This is affecting human livability and maybe pushing it beyond its limit.
