How the climate crisis is heating up Austria

Humanity, through the burning of coal, oil, and natural gas, introduces an additional amount of greenhouse gases into the atmosphere, which act in addition to the natural greenhouse effect.
Due to the additional greenhouse gases, the global average temperature of the Earth has risen by +1.1 °C compared to the pre-industrial period (1850-1900) (IPCC AR6 report). Land masses, like Austria or Europe, have heated up significantly more (+1.59 °C) than water masses like oceans (+0.88 °C).
As soon as we emit no more CO2 than is simultaneously bound (net zero), the Earth's heating would stop. That's initially good news. However, ice sheets and glaciers will still melt and raise the sea level, and the effects of a hotter climate will continue to occur.

An increase in hot days and tropical nights poses a health risk, as they put more strain on the cardiovascular system. Especially older people and people with chronic pre-existing conditions are particularly affected by symptoms. During extreme heat, there is an increase in rescue operations. In addition, people die from the effects of heat stress during hot summers. For Austria, AGES reports a heat-related excess mortality in 2018 of 550 people. In addition, hot days have an impact on agriculture, forestry, infrastructure. Here, the Climate Change Center Austria provides a good overview.

The weather occurs on an hourly and daily basis: Is it currently raining? Is it beach weather on the weekend? In contrast, the climate describes long periods of time, such as several decades or even millennia. Climate changes influence the weather, as the climate crisis increases the frequency, duration, and intensity of weather events, such as droughts or heavy rainfall.

All these days are meteorological terms for days with certain temperature characteristics:

Hot days are days when the maximum daily temperature has been at least 30°C.

Summer days are days when the maximum daily temperature has been at least 25°C.

Tropical nights are days when the minimum daily temperature has not fallen below 20°C. Nights are cooler than the period during the day, between sunrise and sunset. This means, if the minimum daily temperature does not fall below 20°C, the night was a tropical night.

Ice days are days when the maximum daily temperature did not exceed 0°C.

All these days can be determined via the Datahub of the Geosphere for all Austrian weather stations.
