Abstract: Global warming and its influences on world society and economic had caused the attention of all the people in different countries. Predicting the future trend of global temperature change had become a extremely serious problem climate research. It is also rather important to develop new climate detecting technologies to adapt the new characteristics of global warming. So, based on five aspects of climate detecting technologies research: (1) abrupt climate change detecting, (2) separating the useful information of observed data, (3) complexity of climate system, (4) discerning of the dynamical characteristics of climate system, (5) definition and detection of extreme events et al., latest advances of these aspects and their research results are briefly introduced. At last, probable difficulties and key problems in climate change detecting technologies are discussed.
