Climate change & the Role of Forests to Climate Change What are the signs that climate change is occurring? What causes climate change? What is the role of forests in climate change? REDD+ Brief history of REDD+ reddplusethiopia@gmail.com
What is Climate Change? What are the signs of Climate Change? reddplusethiopia@gmail.com
What is Climate Change? reddplusethiopia@gmail.com • Climate Change = significant change in measures of climate (such as temperature or precipitation) lasting for an extended period of time (typically decades) • United Nations Forum Convention on Climate Change (UNFCCC) defines Climate Change as ‘a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere’
Climate Change is happening Four major independent datasets show: 2013 was among the warmest years on record (2nd to 6th)
Sea level is rising: from ocean expansion and melting glaciers • Since 1993 • Global sea level • has risen 37 mm • (1.46 inches) • 60% from • expansion as ocean temperatures rise, • 40% from melting glaciers • Steve Nerem

Climate Change is happening Greenhouse gases continued to climb: Atmospheric CO2 concentration hit a global average of 395.3 ppm for the year 2013

http://maps.grida.no/go/graphic/trends-in-sea-level-1870-2006http://maps.grida.no/go/graphic/trends-in-sea-level-1870-2006 Rising sea levels + 3.1 mm per year • Sea levels are rising due to thermal expansion and melting glaciers and ice caps • Average global sea levels have risen 17 cm during 20th century and may rise 28-58 cm by 2100 Global mean sea level rise from 1870 - 2006 reddplusethiopia@gmail.com
More extreme weather events Severe droughts and heat waves Stronger storms Heavy rains reddplusethiopia@gmail.com
Examples of potential impacts • Forest fire incidence 2008 There are reports that fire has affected more than 200,000 ha every year in recent decades.
Decreasing snow cover and melting glaciers Kilimanjaro 1993 Decreasing snow cover Kilimanjaro 2000 reddplusethiopia@gmail.com http://www.mounteverest.net/news.php?id=1361
Warming of poles and loss of sea ice Collapse of Wilkins Ice Shelf, Antarctica reddplusethiopia@gmail.com
Evidence for reality of climate change Glaciers melting 1909 Toboggan Glacier Alaska 2000 1858 1974 Grindelwald Glacier Switzerland 1900 2003 Alpine glacier, Austria
Evidence for reality of climate change • Tree line shift both altitudinaly and latitudinally. • Traditional change of local communities in their cropping pattern and livestock rearing.
What causes climate change and where are greenhouse gas emissions occurring? reddplusethiopia@gmail.com
Which sectors produce greenhouse gases? reddplusethiopia@gmail.com
Which Sectors Produce Greenhouse Gasses in Ethiopia? reddplusethiopia@gmail.com
Where are greenhouse gases being emitted? Low emissions High emissions reddplusethiopia@gmail.com
Sources of emissions The sources of emissions differ across developing versus developed countries Land use change (deforestation) is a major source (second only to fossil fuels) Greatest source of GHG = fossil fuels reddplusethiopia@gmail.com
Forests in the global carbon cycle reddplusethiopia@gmail.com
Forests Store and Emit Carbon Deforestation & degradation of forests emit 5.87 gigatons of carbon dioxide equivalent Forests & other terrestrial systems - absorb 9.53 gigatons of carbon dioxide equivalent reddplusethiopia@gmail.com
Extent of forests globally Forest area by biome 30% of earth’s land surface is forest (4 billion hectares) reddplusethiopia@gmail.com
Forest carbon globally Carbon stock by biome 45% of terrestrial carbon is stored in earth’s forests • Forests absorb 2.6 gigatons C (9.5 gT CO2) per year • Emissions from tropical deforestation 1.5 gigatons C per year reddplusethiopia@gmail.com
