Climate Change will impact the existing risks including new potential ecological systems and humanity risks. Future global warming situation tend to dramatically spread its effects towards human, living species, and ecosystems; irreversibly and unavoidably. Not only biodiversity, ecological services, and business develop will be negatively influenced, but this also leads to human being, food, and security risks as the results of such phenomenon.

Representative key risks14 for each region, including the potential for risk reduction through adaptation and mitigation, as well as limits to adaptation. Each key risk is assessed as very low, low, medium, high or very high. Risk levels are presented for three time frames: present, near term (here, for 2030–2040) and long term (here, for 2080–2100). In the near term, projected levels of global mean temperature increase do not diverge substantially across different emission scenarios. For the long term, risk levels are presented for two possible futures (2°C and 4°C global mean temperature increase above pre-industrial levels). For each timeframe, risk levels are indicated for a continuation of current adaptation and assuming high levels of current or future adaptation. Risk levels are not necessarily comparable, especially across regions.
IPCC identified risk factors in each region according to sectors that are:
- Severe diseases and dangerous surrounding risks that are affected from storm surges, sea level rises, coastal flooding, urban flooding and severe heat wave.
- Systematic risks from severity of climate change that lead to collapse of infrastructure networks and service critics.
- Food and water insecurity risks and loss in rural livelihood and income of poor people.
- Risks of ecosystem and biodiversity losses and ecosystem functions and services.
