A Hot Year In Europe | Earth Wise

January 5, 2023 By EarthWise Leave a Comment

2022 was a hot year, particularly for Europe

This past summer was marked by some devastating heat waves in Europe.  Through November, the UK, Germany, and France have experienced their hottest year on record.

The UK has experienced its warmest year since 1884 and, in fact, all the top ten warmest years on record have occurred since 2002.

In France, the average temperature for the year is a few tenths of a degree higher than the  previous record, which was set in 2020.

In Germany, the first 11 months of the year saw a record for average temperature.  Its previous record was also set in 2020.

All three countries saw a spike in heat-related mortality as result of the summer heatwaves.  England and Wales reported 3,271 excess deaths during the summer.  France reported 2,816 excess deaths during its three heat waves.  In Germany, an estimated 4,500 people died as a result of extreme heat.

There are multiple effects of climate change which include more frequent heat waves in Europe.  A recent study showed that European summers are warming twice as fast as the global average.  In fact, summer temperatures across much of the European continent have already risen by 3.6 degrees Fahrenheit or 2 degrees Celsius, which is the feared level of global climate increase that nations around the world are trying to stave off.

Worldwide, 2022 will rank among the top ten warmest years on record but will most likely not be the warmest.   That being said, the past eight years are on track to be the eight warmest years on record.  The US will also see one of its ten warmest years, although not the warmest.

Declining Flying Insects | Earth Wise

June 30, 2022 By EarthWise Leave a Comment

In recent years, there has been increasing awareness of the global decline in insect abundance.  A recently published survey of the abundance of flying insects in the UK has revealed very troubling results.

The Kent Wildlife Trust and Buglife – two UK-based conservation groups – compared the number of dead insects on vehicles in 2004 and 2021.  In this Bugs Matter Citizen Science Survey, the data was collected by roughly 20,000 ordinary citizens using a smartphone app.

The results were that the number of flying insects in Britain dropped nearly 60% over that time period.  The insects declined most in England and Wales, with drops of 65% and 55%, respectively. 

It is possible that 2004 was a particularly good year for British insects and 2021 an especially bad one, but the findings of this study are consistent with other research around the world showing an alarming decline in insects.  A series of studies in 2019 found that the global mass of insects is shrinking by 2.5% a year and that insects are going extinct eight times faster than reptiles, birds, or mammals.

Insects face multiple overlapping threats including the destruction of wild habitats for farming, urbanization, pesticides, and light pollution.  On top of these things is climate change which is disrupting ecosystems in multiple ways.

Insects play a vital role in pollinating crops, consuming organic waste, killing pests, and as essential parts of multiple ecosystems.  Severe insect declines can potentially have dire global ecological and economic consequences.

Tipping Points

A tipping point is a point in time when a small thing can make a big change happen.  The term was popularized in sociology in recent decades, but really comes from physics where is refers to adding a small amount of weight to a balanced object causing it to topple over.
