17 heat records broken in Japan
Heatwaves are becoming more intense and frequent worldwide because of human-caused climate change, scientists say, and Japan is no exception.
The city of Komatsu, in the central region of Ishikawa, saw a new record of 40.3 degrees Celsius (104 degrees Fahrenheit) on Monday, the Japan Meteorological Agency (JMA) said.
Toyama city in Toyama prefecture, also in the central region, hit 39.8C (103F), the highest temperature since records began, according to the JMA.
Fifteen other locations across cities and towns soared to new highs between 35.7C (96F) and 39.8C, added the JMA, which monitors temperatures at more than 900 points in Japan.
On July 30, Japan experienced its highest recorded temperature, a sizzling 41.2C (106F) in the western region of Hyogo.
The rainy season ended about three weeks earlier than usual in western regions of Japan, another record.
With low levels of rainfall and heat, several dams in the northern region were almost empty, the land ministry said, with farmers worried that a water shortage and extreme heat could result in a poor harvest.
Experts warn Japan's beloved cherry trees are blooming earlier due to the warmer climate, or sometimes not fully blossoming because autumns and winters are not cold enough to trigger flowering.
The famous snowcap of Mount Fuji was absent for the longest recorded period last year, not appearing until early November, compared with the average of early October.
Japan this year had its hottest June and July since data collection began in 1898, with the weather agency warning of further "severe heat" in the months ahead.
The speed of temperature increases across the world is not uniform.
Of the continents, Europe has seen the fastest warming per decade since 1990, followed closely by Asia, according to global data from the US National Oceanic and Atmospheric Administration (NOAA).

Dangerous heat and humidity build from Toronto to St. John's
A long-duration [spell of extreme heat and humidity]( will continue to blanket much of Eastern Canada into this upcoming week. Temperatures in the middle to upper 30s will combine with high humidity to lead to dangerous conditions for the next several days. Excess moisture in the atmosphere will keep nights muggy, preventing any meaningful relief from the heat of the day. Humid heat affects everyone. Sensitive groups are especially vulnerable to heat-related illnesses, but even healthy folks are susceptible to heat exhaustion or worse in extreme heat. DON'T MISS: Temperatures stay hot into this upcoming week Widespread heat warnings are in effect from Ontario through Newfoundland. This includes cities such as Toronto, Ottawa, Montreal, Quebec City, Fredericton, Charlottetown, Gander, and St. John's. A strong ridge of high pressure parking over Eastern Canada will lead to numerous days of high heat combined with excessive humidity, which could lead to feels-like values in the upper 30s to around 40 at times. Multiple cities—including Toronto, Ottawa, and Montreal—are in the midst of a four- to five-day stretch of daytime highs at or above 30°C. Saturday marked the third day this year we've seen a high temperature at or above 30°C in St. John's, making for the highest number of 30-degree days ever recorded in a single year. This Saturday also featured Toronto's nineteenth day at or above 30°C so far this season, pushing the city past its average of 17 such days per year. MUST SEE: The extreme heat and lack of precipitation has allowed conditions to reach 'very high' to 'extreme' fire danger across much of Atlantic Canada. Widespread burn bans are in effect across all four provinces. Why humid heat is dangerous Sweat cools us off by wicking heat away from our skin as it evaporates. Humidity prevents our sweat from evaporating efficiently—the trapped heat causing our body temperature to rise. This can lead to heat-related illnesses such as heat exhaustion and heat stroke. RELATED: Humidity also prevents nighttime lows from cooling off as much as normal, providing little to no relief from extreme daytime temperatures. Day after day of high heat and humidity take a toll on those living without air conditioning, folks who have chronic illnesses, and the elderly. Seek out air conditioning as much as possible, stick to the shade, stay well hydrated, and frequently check in with your vulnerable friends, family, and neighbours.
