Climate Change & Biodiversity

Some species may benefit from climate change (including, from a human perspective, an increases in diseases and pests) but the rapid nature of the change suggests that most species will not find it as beneficial as most will not be able to adapt.

What is Climate Change? 

People make lots of CO2

→ So much CO2 cover the air like blanket

→ The blanket of CO2 can make air too hot

→ This is called CLIMATE CHANGE 

  

 
 

What is biodiversity and why it is important?

 

Biodiversity is the variety of animals and plants found on this planet including the geogrphic locations they are found in.

It is impotant for sustaining life on earth because it prevents any one species from throwing the balance of nature out of order.

there are so many articles about CLIMATE CHANGE and it's

Climate Change Affects Biodiversity

         by Anup Shah, This Page Last Updated Sunday, March 04, 2012

         The link between climate change and biodiversity has long been established. Although throughout Earth’s history the climate has always changed with ecosystems and species coming and going, rapid climate change affects ecosystems and species ability to adapt and so biodiversity loss increases.
From a human perspective, the rapid climate change and accelerating biodiversity loss risks human security (e.g. a major change in the food chain upon which we depend, water sources may change, recede or disappear, medicines and other resources we rely on may be harder to obtain as the plants and forna they are derived from may reduce or disappear, etc.).
The UN’s Global Biodiversity Outlook 3, in May 2010, summarized some concerns that climate change will have on ecosystems:

 "Climate change is already having an impact on biodiversity, and is projected to become a progressively more significant threat in the coming decades. Loss of Arctic sea ice threatens biodiversity across an entire biome and beyond. The related pressure of ocean acidification, resulting from higher concentrations of carbon dioxide in the atmosphere, is also already being observed.
Ecosystems are already showing negative impacts under current levels of climate change … which is modest compared to future projected changes…. In addition to warming temperatures, more frequent extreme weather events and changing patterns of rainfall and drought can be expected to have significant impacts on biodiversity."

— Secretariat of the Convention on Biological Diversity (2010), Global Biodiversity Outlook 3, May, 2010, p.56
