Climate Change: Carbon<br />
Budget and Relevant Issues<br />
To confront climate change issues and find an optimized<br />
approach for sustainable development in<br />
China, a program has been put in place that aims<br />
to tackle a series <strong>of</strong> S&T issues by bringing together<br />
multiple disciplines at CAS. Issues to be add<strong>res</strong>sed<br />
include quantitative verification <strong>of</strong> the total ter<strong>res</strong>trial<br />
carbon budget <strong>of</strong> China, identification <strong>of</strong> opportunities<br />
for creating/strengthening carbon sinks, developing<br />
the means to create/strengthen these carbon<br />
sinks, and analyzing the relationship between the<br />
increase in greenhouse gases and future global climate<br />
change.<br />
This program is expected to meet the fol<strong>low</strong>ing<br />
goals: (i) to build a system <strong>of</strong> data <strong>res</strong>ources, scientific<br />
knowledge, and supportive technologies for the<br />
creation <strong>of</strong> national policy on reducing greenhouse<br />
gases and strengthening carbon sink potential as<br />
well as implementing strategic decision-making<br />
for sustainable development <strong>of</strong> the nation; (ii) to<br />
significantly improve the quality <strong>of</strong> domestic <strong>res</strong>earch<br />
in fields such as ecological systems and climate change, quantification<br />
and verification <strong>of</strong> territorial carbon budget, technologies and measu<strong>res</strong> to<br />
strengthen carbon sinks in ecological systems, and managerial policies for<br />
regional carbon budgets as well as to achieve a significant improvement in<br />
S&T development as a basis for add<strong>res</strong>sing climate change and increase<br />
China’s role in the international climate change community; and (iii) to<br />
establish a team <strong>of</strong> high-level S&T pr<strong>of</strong>essionals capable <strong>of</strong> dealing with the<br />
current trend <strong>of</strong> integration <strong>of</strong> different disciplines.<br />
This program will set up a total <strong>of</strong> 15 subprojects to pursue its goals,<br />
falling into five task clusters: greenhouse gas emissions, carbon sequestration<br />
<strong>of</strong> ecological systems, sensitivity to climate change, impacts <strong>of</strong> and<br />
<strong>res</strong>ponses to climate change, and green development.<br />

By reforming<br />
the existing way<br />
that IT <strong>res</strong>earch<br />
is conducted,<br />
technology and<br />
scientific <strong>res</strong>earch<br />
can be improved.<br />
Next Generation Sensor<br />
Technology Research in China<br />
A strategic priority <strong>res</strong>earch program in<br />
next generation information technology (IT)<br />
<strong>res</strong>earch has been established in China<br />
that aims to meet growing demands for a<br />
countrywide network <strong>of</strong> sensors, including<br />
information sensing equipment, information<br />
transmission, and information processing<br />
equipment. The overarching challenges<br />
to a widely distributed sensor network are<br />
power dissipation, performance, cost, and<br />
security. This program is based on the innovative<br />
concept <strong>of</strong> fusing humans, computers,<br />
and physical systems into a Human<br />
Computer Physical Network Cloud.<br />
To fully utilize the opportunity <strong>of</strong> this triple<br />
Figure 3. A new generation <strong>of</strong> IT-based on systematic,<br />
transformative innovation.<br />
integration, the concept <strong>of</strong> a so-called Sea-Network-Cloud (a sea <strong>of</strong> sensors<br />
connected to a transmission network, all linked to a processing cloud)<br />
has been proposed and a test platform built. By reforming the existing<br />
way that IT <strong>res</strong>earch is conducted, technology and scientific <strong>res</strong>earch can<br />
be improved, while simultaneously establishing a technical foundation for<br />
bringing together technological, infrastructural, and social <strong>res</strong>ources.<br />
This program promotes the real-world evolution from 2-D to 3-D integration<br />
through the fusion <strong>of</strong> human, computer, and physical systems by<br />
combining Zettabyte (ZB)-level data, Sea-Cloud processing (the collection<br />
and processing <strong>of</strong> data from the sensors and the deposition <strong>of</strong> this<br />
data into a central processing center), end-to-end evolved networks with<br />
quality assurance, and sensors collecting data about the physical world.<br />
The program is designed to provide key technical support for the construction<br />
and development <strong>of</strong> a more intelligent, secure, and serviceoriented<br />
information society. To achieve this goal, a systematic and innovative<br />
new generation IT technology has to be developed, as shown<br />
in Figure 3.<br />
This program will face significant scientific challenges, including: developing<br />
a system architecture for IT technology over the next 20 years<br />
that is designed for efficiency; limitations in the ability to simultaneously<br />
collect and process large amounts <strong>of</strong> data; the evolution, robustness,<br />
adaptability, and manageability <strong>of</strong> the future network; providing<br />
easy access to large amounts <strong>of</strong> complex information from heterogeneous<br />
sources; and developing a secure IT system that balances cost<br />
and efficiency.<br />
CAS has initiated a number <strong>of</strong> international collaborations around the<br />
Sea-Network-Cloud. This program aims to further international collaboration<br />
on the evolution <strong>of</strong> IT infrastructure and the development <strong>of</strong> highperformance<br />
computing as well as high-performance core routers. This will<br />
create a foundation for building out future information and sensor networks,<br />
provide effective access to information, and achieve effective and more<br />
intelligent management <strong>of</strong> natural <strong>res</strong>ources and maintenance <strong>of</strong> information<br />
security.<br />
