PART 2

Since the 1950s, and in

particular after 2000, Europe

has increasingly experienced

heat extremes and heat waves.

adapt to the unavoidable impacts of

past and future climate change. In

summary, the short-term adaptation

challenges are largely independent

of mitigation efforts, whereas the

long‐term climate challenge, and

societies’ ability to adapt to it, are

strongly dependent on the success of

global mitigation efforts.

There can be synergies as well as

trade‐offs between climate change

mitigation and adaptation objectives.

One strategy that often brings about

mitigation as well as adaptation benefits

is ecosystem-based adaptation. This

is a nature-based solution that uses

ecosystem services as part of an overall

strategy to increase the resilience and

reduce the vulnerability of communities

to climate change (Secretariat of the

Convention on Biological Diversity, 2009).

Examples include natural water

retention measures and green

infrastructure (EC, 2013c; NWRM, 2019).

Ecosystem‐based adaptation can

generate many environmental, social,

economic and cultural benefits

(EEA, 2017b; EC, 2018b). For further

information, see the Climate‐ADAPT

platform ( 5 ). Ecosystem‐based adaptation

can also contribute to climate change

mitigation by reducing emissions caused

by ecosystem degradation and/or by

enhancing carbon stocks. An example

of trade-offs between adaptation

and mitigation is energy-intensive

desalinisation or air conditioning based

on fossil fuels.

7.3.4

Climate change and its impacts on

ecosystems

►See Table 7.7

All ecosystems, many economic

activities and human health and

well‐being are sensitive to climate

variability and change. This section

gives an overview of key changes in the

climate system in the past and future,

and of selected impacts on ecosystems.

More detailed information on this topic

is available in the EEA report Climate

change, impacts and vulnerability in

Europe 2016 — an indicator based report

(EEA, 2017c). Specific information about

the European climate in a particular

year is available in the European

state of the climate reports published

annually by the C3S (C3S, 2018a).

Average temperature

Global average annual near-surface

(land and ocean) temperature in

the last decade (2009-2018) was

about 0.91‐0.96 °C warmer than the

pre‐industrial average (1850-1899)

(Figure 7.6). The European land area has

warmed by 1.6-1.7 °C over the same

period, with significant regional and

seasonal differences. Of the 19 warmest

years on record globally, 18 have

occurred since 2000 (EEA, 2019f).

All UNFCCC member countries

have agreed on the long-term goal

of keeping the increase in global

average temperature to well below

2 °C compared with pre-industrial

levels and have agreed to aim to limit

the increase to 1.5 °C. About half of

the maximum admissible warming

under the Paris Agreement has

already been realised. For the three

highest of the four representative

concentration pathways (RCPs,

loosely known as emissions scenarios)

considered by the Intergovernmental

Panel on Climate Change (IPCC), the

global mean temperature increase is

projected to exceed 2 °C compared

with pre‐industrial levels during the

21st century, and most likely in the

2040s (IPCC, 2013; Vautard et al., 2014).

‘Very deep and rapid global emissions

reductions, requiring far-reaching

transitions in all sectors of the economy,

are necessary to keep the chance of

limiting global mean temperature

increase to 1.5 °C (IPCC, 2018).’

Heat extremes

Annually averaged land temperatures

in Europe have increased considerably

faster than global temperatures

(see above), and daily maximum

temperatures in Europe have increased

much faster than annually averaged

temperatures. This means that a given

increase in global mean temperature is

associated with a much larger increase

in heat extremes in Europe.

Heat extremes and heat waves in

Europe have increased considerably

since the 1950s, and in particular

after 2000. Since publication of

the SOER 2015, all-time national

temperature records were broken in

eight EEA member countries (Poland

in 2015, Spain in 2017 and Belgium,

France, Germany, Luxembourg, the

Netherlands and the United Kingdom

in 2019), several of them with a large

margin. In the same period, national

records for the warmest night, which

is particularly relevant from a human

health perspective, were broken in

nine countries (Austria in 2015, France

and Slovenia in 2017, the Netherlands
